To facilitate the installation of photovoltaic systems on the roofs of buildings serving activities subject to fire prevention controls, given the high number of requests for the ongoing energy emergency, the legislator with the Legislative Decree 144/2022 (GU no. 223 of 23 September 2022), in art. 16 established that in the event that, following the installation of these types of systems, the evaluation of the fire prevention project is necessary, the terms for the binding opinion of the Fire Brigade. are reduced, until 31 December 2024, from sixty to thirty days, in order to streamline the bureaucratic process.

 

Changes to subject activities

 

Photovoltaic systems are not included among the activities subject to fire prevention control as they are not included in the list in Annex 1 of the Presidential Decree. 151/2011.

However, the installation of a photovoltaic system serving an activity subject to fire prevention controls undoubtedly involves a change to the fire risk assessment drawn up by the qualified technician, whose management is regulated by the Ministerial Decree. 7 August 2012, which provides for differentiated obligations depending on whether the changes are:

- « Not substantial » (it is sufficient to declare them when certifying periodic renewal).

- «Without worsening» the pre-existing fire safety conditions (a new certified notification of commencement of activity must be submitted).

- With worsening of the pre-existing fire safety conditions (a new project examination must be submitted).

 

Evaluation of changes

 

The evaluation of the type of modification is carried out by the designer through a risk assessment aimed at identifying the most suitable solutions to achieve the fire safety objectives.

The professional will be able to take into account the technical solutions contained in the DCPREV prot notes. n. 1324 of 7 February 2012 and n. 6334 of 4 May 2012, although they must not be considered as prescriptive indications.

"Photovoltaic system serving an activity subject to fire prevention controls" means a system incorporated into the subject activity, independently of the end user, or a system whose modules fall, even partially, within the volume delimited by the cylindrical surface. vertical having as its generator the plan projection of the building, including overhangs and eaves.

 

 

Fire prevention requirements

 

If the fire risk assessment reveals a worsening of the pre-existing fire safety conditions, examination of the project must be requested (for category B and C activities) from the Provincial Fire Brigade Headquarters and, once the works are completed, it must be presented the certified Report of commencement of activity before the start of the activity.

However, if no worsening of the pre-existing fire safety conditions emerges, the application must be updated with the presentation of the Scia.

In case of presentation of the Scia without prior approval of the project, the documentation must be integrated with the risk assessment.

 

Case of «increased risk»

 

The installation of a photovoltaic system can lead to an increase in the pre-existing level of fire risk for the business served, depending on the electrical and construction characteristics and methods of installation.

In evaluating this possible "increased risk" for the legislator, the following aspects must be taken into consideration to allow the identification of the obligations set out in the art. 4, paragraph 6, of the Presidential Decree. n. 151/2011:

> Interference with the combustion product ventilation system such as, for example, partial/total obstruction of translucent elements, impediments to the opening of the vents.

> Obstacle to cooling or extinguishing operations on combustible roofs.

> How the fire spreads in a building of the flames outside or towards the inside of the building (presence of pipes on the roof of a building divided into several compartments, modification      of the speed of spread of a fire in a single compartment building) .

> Safety of maintenance operators.

> Safety of rescue operations workers.

 

Technical requirements

 

From a safety point of view, it must be taken into account that it is impossible to de-energize the system in the presence of sunlight.

This constitutes an element of attention not only during the construction and maintenance phase of the photovoltaic generator, but also in the event of an emergency intervention.

For the purposes of fire prevention, PV systems must be designed, built and maintained in a workmanlike manner.

Where the systems are carried out according to the technical documents issued by the CEI (standards and guides) and/or by the international standardization bodies, they are considered to have been carried out in a workmanlike manner.

All components must comply with applicable community or national provisions.

The installation must be carried out in such a way as to avoid the spread of a fire from the photovoltaic generator to the building in which it is incorporated.

 

This condition is considered respected if the photovoltaic system is installed on non-combustible structures and roofing elements (Class 0 according to the Ministerial Decree 06/26/1984 or Class A1 according to the Ministerial Decree 03/10/2005).

 

The interposition between the photovoltaic modules and the support surface of a layer of fire-resistant material of at least EI 30 and non-combustible is also equivalent.

Alternatively, a specific assessment of the risk of fire spread may be carried out.

In addition to the risk assessment, other assessments aimed at demonstrating the achievement of the objectives of the guide are eligible.

In the DCPREV note n.6334 of 04/05/2012 the different methods for satisfying the safety requirement relating to the risk of fire spread were summarized.

If it is intended to take into account the external fire resistance class of roofs and roof coverings and the reaction to fire class of the photovoltaic module (case 3/a of Annex B), the following can generally be considered acceptable pairings:

> Roofs classified Froof and PV panel class 1 or equivalent reaction to fire.

> Roofs classified as Broof (T2, T3, T4) and PV panel class 2 or equivalent reaction to fire.

> Final roofing layers (waterproofing and/and insulation packages) classified Froof or F installed on EI 30 roofs and class 2 PV panels or equivalent reaction to fire.

 

 

 

The location of the modules and electrical conduits must also always allow the correct functioning and maintenance of any smoke and heat evacuators (EFC) present, as well as taking into account, based on the fire risk analysis, the existence of possible fire transmission routes (skylights, chimneys, etc.).

In any case, the modules, ducts, inverters, panels and any other equipment must not be installed within a radius of 1 m from the EFCs.

Furthermore, in the presence of vertical fire compartmentation elements, placed inside the activity underneath the support surface of the photovoltaic system, the same must be at least 1 m away from the projection of these elements.

The PV system must also have the following characteristics:

> Be equipped with an emergency control device, located in a marked and accessible position which determines the isolation of the electrical system, inside the compartment in relation to the power sources, including the photovoltaic system.

> In the event of the presence of gases, vapours, flammable mists or combustible dusts, in order to avoid the dangers caused by electrical ignition, it is necessary to install the direct current part of the system, including the inverter, outside the classified areas pursuant to Legislative Decree 81/2008 - annex XLIX.

> In places with danger of explosion due to the presence of explosive material, the photovoltaic generator and all other direct current components constituting potential ignition sources must be installed at the safety distances established by the applicable technical standards.

> The components of the system must not be installed in places defined as "safe places" pursuant to Ministerial Decree 30/11/1983, nor be an obstacle to escape routes.

 

In-depth analysis by the eng. Matteo Pierotti

The full-blown climate changes, the still indispensable use of fossil fuels, such as:

> Oil;

> Natural gases.

They have transformed the priorities of investment-related risks.

ESG (Environment, Social & Governance) sustainability factors have now become an essential factor for every manufacturing and non-manufacturing company.

In recent years, the governments of countries around the world have signed unprecedented global agreements, which will be able to radically change investment policies, pushing the transformation towards a sustainable and environmentally compatible economy, promoting and supporting a "global energy transition", through economic support of various types, in the various industrial sectors.

The European Union, in addition to launching an important Multi-Year Financial Plan in support of the "green deal", has taken the field considerably and has decided to accelerate the energy transition processes, bringing forward important targets to 2035.

Financial markets are also moving in this direction, establishing real regulatory authorities, linking climate risk into the global financial system.

 

 

As? By changing the ratings of financial companies, should they not declare a "green" sustainability and investment policy.

Finally, in this historical and economic period, "sustainability" fortunately goes hand in hand with "ethics", pushing many companies to undertake management and therefore investment paths, focusing on ESG factors, coupled with corporate ETHICAL VALUES and governance.

It is therefore not a question of promoting cheap "green washing" actions; on the contrary, companies are betting heavily on the opportunity for deeper and more rooted growth, a cultural evolution capable of generating true corporate values, which are necessarily reflected both in management and in short/medium and long-term investments.

 

How does this epochal cultural change in governance happen within a company, focusing on ESG factors?

Many companies, especially public ones and those listed on stock exchanges around the world, have extended ESG policies to social and ethical policies, certifying and publishing short/medium and long-term ESG strategies and defining the targets to be achieved therein.

At the same time, together with the half-yearly reporting on company performance, they have the obligation to publish a specific reporting file on the development of ESG factors.

Generally, large companies lead the way in the markets and therefore this trend must necessarily be read from a "button down" perspective.

It is no coincidence that many small companies have certified themselves and have already published their first sustainability reports, declaring their short/medium and long-term investments.

We are mostly talking about highly energy-intensive manufacturing companies that have implemented their range of products with the use and/or addition of "bio-materials", but also production companies that by strategic choice have opted for a policy of investments aimed at increasing energy efficiency and improving the working environment, adapting production sites and building envelopes, such as: installing systems that generate electricity from renewable sources, general revamping of consumer equipment, changing fixtures, coats thermal, boiler replacement with heat pumps, disposal of asbestos cement and other preparatory activities.

 

But let's go into specifics, what are ESG certifications?

They are a series of operational standards that a company's strategies must comply with.

These certifications evaluate the sustainability of organizations, in particular their ability to align with a series of fundamental requirements for sustainable development from the economic, environmental, social and governance points of view of the company.

 

 

Sustainability has three dimensions.

ESG is an acronym (Environmental, Social & Governance).

> Environmental Area (E), includes environmental factors, i.e. the way in which an organization contributes to the protection and management of the environment.

> Social (S) scope includes services, i.e. the impact in which an organization interacts with the territory and with people, be they employees, suppliers and customers.

> Governance Area (G), includes strategies, i.e. the way in which an organization intends to apply the first two factors within the company.

 

How to obtain ESG certification?

ESG sustainability is becoming a central theme in the corporate world at all levels and dimensions.

Companies that demonstrate a strong commitment to these principles can obtain ESG certification, which is a certificate that certifies and qualifies them for their commitment to sustainability.

Before undertaking the ESG certification process, it is crucial to have a thorough understanding of ESG criteria and key existing standards, such as the Global Reporting Initiative (GRI), the United Nations Global Compact (UNGC) and the Sustainability Accounting Standards Board (SASB). ).

These standards provide guidance on key areas of sustainability and how to measure corporate performance in those areas.

Once you understand ESG criteria, it is important to “conduct an internal assessment” to understand the current state of the company's ESG performance.

 

How? Analyzing financial data, identifying environmental and social risks and planning improvement strategies.

“Strategies play a key role in the certification process”: the strategic definition is necessary to establish the objectives and the investments to be made to achieve them.

Once the strategy has been defined, it is necessary to implement the measures for monitoring the results over time.

This may involve collecting specific data and integrating sustainable processes and procedures within daily business activities.

 

ESG certification

After conducting the internal assessment and measuring the company's ESG performance, the certification process can be started.

There are several organizations offering ESG certification, each with their own requirements and evaluation criteria.

It is important to select a recognized and trusted certification that aligns with industry standards and expectations.

Once ESG certification has been obtained, there is an obligation to communicate the results transparently to the outside world, for example to shareholders, employees, suppliers and customers.

This can be done through the publication of periodic sustainability reports.

By following the steps described above and demonstrating a solid commitment to sustainability and ESG factors, companies can not only contribute to a more sustainable future, but also achieve tangible business benefits recognized by the market.

 

 

ESG Auditors and Certifiers?

ESG certifications are issued by various independent organizations specialized in the sector.

Some of the most internationally recognized are:

> Global Reporting Initiative (GRI)

The GRI is a non-profit organization that promotes the dissemination of information on the environmental, social and governance impact of companies. The GRI provides guidelines and standards for preparing sustainability reports and does not issue certifications, but it helps companies develop and improve their ESG performance.

> Carbon Disclosure Project (CDP)

The CDP is an international organization that requires companies to disclose their greenhouse gas emissions and strategies for dealing with climate change.
Companies participating in the CDP receive a transparency and climate action score, but not a specific certification.

> Rating agencies.

Some independent rating agencies, such as Moody's, S&P Global and MSCI, also evaluate companies' ESG performance.
These agencies use specific metrics to score or rate companies based on their ESG engagement and performance.

 

Costs of ESG certification?

The costs for obtaining an ESG certification can vary according to the organization issuing it and above all according to the company size.

Logically, the greater the commitment to sustainability, the higher the costs will be.

It is advisable to contact your chosen ESG certification organization directly to obtain accurate cost information.

 

Long-term benefits and vision.

The corporate world rationally tends to compare COSTS vs BENEFITS.

What benefits could a company have that opts to invest in sustainability by certifying ESG factors?

From our point of view we could consider three types of benefits and economic returns:

> The first is a SHORT-TERM BENEFIT, commercial recognition of customers on individual products. The ESG certified customer recognizes the ESG supplier an extra plus (either economic or in terms of product volumes) compared to the non-ESG certified supplier;

> The second is a MEDIUM/LONG-TERM BENEFIT, economic return on sustainable investments, in terms of economic savings over time.
These investments have an average payback time of 4/5 years and will allow companies to see the first tangible benefits only after this period of time.

> The third is a LONG-TERM BENEFIT, based on the classic hierarchy of the supply chain in the corporate world (Producer OEM, Tier1 supplier and Tier2 supplier), in the long run there will be an increasing tendency to qualify only ESG certified suppliers.
ESG certification is a process that is starting now, and which in fact is mainly involving (OEM producers) and some first-level suppliers (Tier1).
Therefore this selectivity mechanism must necessarily be seen in the long term.

The companies that decide today to invest by certifying ESG factors are mainly those players who have a long-term vision, who do so because they create tangible value for the entire company system and not for an immediate improvement of their economic account.

 

 

The Inveco Group's interest in ESG factors

In recent years, our renewable energy business unit has grown significantly, both in organizational terms and in terms of business volume.

This success was certainly made possible thanks to our experience as a general contractor in the industrial world and careful planning and commercial strategy.

Above all this, however, there was the presence of a strong MARKET DEMAND.

It is precisely the specific analysis of the question that presents us with a more appropriate and in-depth reflection: "the demand encountered in recent years to make industrial building envelopes more efficient, the strong development of renewable energy, primarily the installation of rooftop photovoltaic systems, have they already reached the end of the line”?

“Will the investments of industrial players continue at the current volumes or will they have contractions in the coming months that will send companies like ours into crisis?” – “Has the fear effect of a company that saw the cost of kWh skyrocket in 2022, then return to pre-shock levels, more or less market-level, already over?”

The answer to these simple and obvious questions that many entrepreneurs are certainly asking themselves today is, in our humble opinion: NO.

The ESG certifications are proof of this, because if the corporate world, strongly stimulated by international institutions, has taken this route and undertaken strategic decisions based on instrumental investments, the answer can only be a firm "NO".

It is here that we glimpse our growth opportunity, first of all a "cultural growth" that can conceive and understand the true strengths behind sustainability, factors that are apparently intangible but which create value in the company.

Again from our modest point of view, ESG certifications are an example of how the corporate world is evolving and will not do so in 30 years, it is already doing so and will continue to do so.

 

(plant built in March 2023 for ICSS Group, an ESG certified company)

 

The Inveco Group's commitment will be to implement ISO 9001 with ISO 14000 by 2024, at the same time conducting "an internal assessment" to understand the current state of the company's ESG performance and begin strategically planning business objectives. 'investment.

The Inveco Group is sensitive to issues related to sustainability and sees long-term opportunities in the energy transition supported by corporate cultural growth.

Upon returning from summer holidays, the entire Inveco Group team made use of their time by starting a process aimed at improving "internal communication".

The first session of the course was held on Tuesday 5 September together with the Business Coach, Stefano Orazi.

In this first session, the program of the course was illustrated, the methods of involvement of each resource and the objectives were defined.

In the next month, a new operational organization chart will be developed divided by Business Unit (Renewable Energy - Industrial Construction - Real Estate), the operational job description of both individual resources and departments will be completely revised.

Finally, new "internal communication" procedures will be created which will allow the team to work with greater precision and responsibility, maximizing working time and performance.

 

 

Filippo Barbetti - CEO

“We are questioning ourselves!

This aspect is fundamental within the company, we are people and we all have a great need to communicate. I saw a lot of enthusiasm and this leads me to think in the long term, there is a desire to grow and improve, there is a desire to think big.

When you are at the top of a company, of your company, and you perceive these stimuli from your team, you must know how to seize the opportunity and present a project to your collaborators that can improve their lives on a professional and everyday level."

 

 

Andrea Girelli - OPERATION MANAGER

“The Inveco Group staff had the opportunity to discuss the topic of internal communication: being able to share a strategic plan of objectives with all the people who work and transmitting the company culture are two aspects on which it was decided to invest time and resources .

Specialized consultants have shown us how better communication within the company contributes to increasing people's engagement and reaching business goals faster.

The Inveco Energy business unit is evolving very quickly and the set goals cannot ignore an improvement in information flows between the various company functions.

The objective is to increase productivity (operations) on the one hand and at the same time spread a continuous critical comparison that leads to continuous innovation of the services provided to customers."

 

 

Matteo Pierotti - PROJECT MANAGER

“Communication is a daily, natural action that puts you in relationship with other people, but this is not always rapid, precise and above all effective as is required in a work context, where everyone must speak 'the same language'.

Correct internal communication contributes to the functioning and development of the company, involving all people more, motivating them and at the same time allowing us to improve the climate and the working environment, making it even more 'ecological'.

So, without a doubt, applause for this initiative!”

 

 

Stefano Orazi BUSINESS COACH.

“The work done on Tuesday 5 in the company was the starting point for a series of meetings that will lead us to improve company tasks and activities.

This is because the company has been experiencing a desire for improvement and constant growth for almost 2 years now.

I was very impressed by the participation of all the members of the company both physically and mentally during the work done in Team Coaching.

Working together has led them to look at the company and their department from many points of view and this is useful in improving internal communication between departments.

It's the beginning of a journey.”

The recent company growth in recent years, both in terms of staff and volume of business, obliges us to improve both the working environment and the operating procedures and therefore internal communication will have to evolve accordingly.

Over the years, the Inveco Group has always been attentive to growth processes, valuing the team and people first and foremost.

The process undertaken in recent days is testimony to this.

From January until the end of August, various photovoltaic plants were carried out, a total of 6, plus another 3 which are being installed, another 2 new orders will be started at the beginning of October with connection forecast by 31.12.2023.

The last project that will start this autumn is a Greenfield Project in the Municipality of Foggia, and will have a two-step installation deadline (1MW+2MW) and will be completed by 2024.

Below we want to leave you a glimpse of what was the work of our Project Managers and how the future of our customers, after the installation of the systems, will be decidedly greener, in line with the declared industrial investment policies according to the ESG (Environmental Social Governance) sustainability principles.

On May 12, 2023 we published a news in which 5 photovoltaic plants were declared concluded, click here to read it.

Castello Italia S.p.a - Casalmorano (CR)

 

 

It is the sixth plant that entered into operation in 2023, precisely on 2 February.

The 602 kW photovoltaic system was built on the industrial roof of the Casalmorano (CR) plant of our customer Castello Italia S.p.a.

1,116 Jinko Solar Tiger neo 540 Watt photovoltaic modules, a very large and powerful module that goes very well with the current industrial coverage, to which 5 SOFAR-100KTL-M1 inverters and 1,116 TIGO optimizers are connected which have the dual function of optimizing the system in the event of shading and to instantly cut off the direct current on the roof in the event of a fire.

The estimates of average annual producibility amounted to 670,000 kWh on average per year, of which 96% will be self-consumed and the remaining 4% fed into the grid.

Thanks to the self-produced solar energy, Castello Italia S.p.a will save about 30% in terms of energy costs every year.

The three plants currently being installed are for customers Rustichella D'Abruzzo SpA (Moscufo plant), Modulo Tools Srl and Anodall Extrusion S.p.A.

 

Rustichella Spa (plant of Moscufo) - EU Tender “Parco Agrisolare".

 

 

This project was part of the EU tender "Parco Agrisolare" - Investment 2.2 of the PNRR Mission 2 "Green revolution and ecological transition", Component 1 "Circular economy and sustainable agriculture".

The intervention is aimed at the self-production of electricity through 367 Jinko Solar modules and 2 inverters.

The power of the photovoltaic system is equal to 208 kWp with an energy production of approximately 364,000 kWh, capable of almost totally satisfying the energy needs of the industrial pasta factory in Moscufo.

Modulo Tools S.r.l – Regione Umbria Tender “Solar Attack”.

 

 

Modulo Tools is an engineering company in the automotive sector, located in Umbertide (Perugia) and founded in 1995.

The new photovoltaic project intended to cover the production site involves the installation of 133.92 kWp, for an annual production of approximately 150,000 kWh, making it possible to achieve almost 50% energy independence.

The plant will be financed in part through the funds of the "Solar Attack" tender, the project in fact placed first in the ranking for the allocation of funds.

Anodall Extrusion S.p.A.

 

 

On 5 June 2023, the managing director Dr. Filippo Barbetti signed an order with Marco Pedrocchi (CEO Anodall) for the future installation and construction of a 3 mW photovoltaic system.

The contract will see us active in the Veneto precisely in the Municipality of Trevenzuolo (VR).

Thanks to the collaboration of the Project Manager Arch. Alberto Minozzi, Anodall came to the conclusion that to obtain the desired powers, the project had to be framed as a whole with the renovation of 15,000 square meters of the roof of the main plant.

This intervention would have allowed us to increase the system from 900 kW to 2 mW on that single portion of the roof.

Anodall's strategic choice has become decisive by involving ISCOM S.p.A. in the project, a leading company in the industrial roofing sector, which with its "riverclack" patent can develop large-surface roofing projects, guaranteeing 100% watertightness.

Finally, the last mW was designed on the remaining roofs of the Trevenzuolo plant, thus arriving at the desired power since the origin of Ing Pedrocchi.

The photovoltaic modules that will be used are the JINKO SOLAR Tiger Neo N-type JKM564-585N-72HL4 (570 watt model), combined with GROWATT 125KTL 3-XLV multi-string inverters.

The plant will be divided into 4 distinct portions by type of roof.

> Portion 1 (riverclack) 2,042.31 kWp, number of modules 3,583.

> Portion 2 (shed) 287.28 kWp, number of modules 504.

> Portion 3 (offices) 63.84 kWp, number of modules 112.

> Portion 4 (2nd plant) 610.47 kWp, number of modules 1,071.

Thanks to this plant capable of generating 3,295,000 kWh annually, Anodall will be 25% autonomous with respect to its own consumption.

In fact, 95% of the annual producibility will be aimed at self-consumption, considerably reducing the operating costs of electricity, allowing the customer an economic return on the investment (Payback Time <5 years).

The remaining energy will be fed into the national grid, mainly in the month of August.

The two plants that will start in October are for customers Rustichella D'abruzzo SpA (Pianella plant), Poliforce Srl.

 

Rustichella D’abruzzo S.p.A. (plant of Pianella) - EU Tender “Parco Agrisolare.

 

This project was also included in the EU tender "Parco Agrisolare" - Investment 2.2 of the PNRR Mission 2 "Green revolution and ecological transition", Component 1 "Circular economy and sustainable agriculture".

The intervention is aimed at the self-production of electricity through 614 Jinko Solar modules and 3 inverters.

The power of the photovoltaic system to be installed will be equal to 350 kWp with an energy production of approximately 455,000 kWh, capable of almost totally satisfying the energy needs of the two Pianella plants.

In the first plant, in Pianella in 2022, 150 kWp had already been installed for the same customer.

 

Poliforce S.r.l.

 

 

On July 10, we signed a new contract with the company POLIFORCE S.r.l. and this remains yet another testimony that in the spring we worked well in Gropello Cairoli, the headquarters of the ICSS Group.

Poliforce S.r.l. is a company belonging to the ICSS group, which deals with the design, production and wholesale of packaging and products in plastic, paper, synthetic and wooden materials.

At the time, we installed 384 kW allowing the plant to have 20% energy autonomy.

Instead, this new contract provides for the installation of 424 kW, 744 Jinko Solar modules of 570 watts and 3 Growatt inverters of 125 TL.

According to the plans, the customer will start the renovation work on the industrial roof in September and the plant will be built later in the Autumn.

On a forecast basis, it will be able to produce 474,000 kWh of clean energy annually, 80% of which is for self-consumption, i.e. around 380,000 kWh on an annual basis.

With this system, the Sermide (MN) plant will be 56% autonomous.

Finally, the mega project on the ground in the Municipality of Foggia where the works will begin in the coming months with completion expected by 31.12.2024.

 

Greenfield Project

The photovoltaic plant in question will be on the ground of approximately 3 MW and foresees the construction in two steps.

> First step 1 MW.
> Second step 2 MW.

 

 

The plant obtained the PAS (simplified authorization procedure) from the Municipality of Foggia, and the TICA of Enel Distribuzione S.p.A., of the first step, was accepted.

The TICA (integrated text of active connections) establishes the methods and technical-economic conditions for connecting electricity production plants to the national grid.

The construction site for the first step will begin in October and from a technical point of view our operational mission will be that of coordination and project management, until the photovoltaic plant is put into operation.

Conclusion

A total of 12 projects developed in just over 12 months, which make the work of our team proud and which make the renewable energy "Business Unit" the flagship of the Inveco Group, enriching our international experience as General Contractor.

We are talking about a volume of business that is close to 10 million euros, a total of 9 MW of industrial plants aimed mainly at the self-consumption of the production plants.

Apart from the Foggia onshore project, in fact, the above-retired energy will go under the SSP regime (on-the-spot metering) avoiding additional dispatching and transport costs for the national grid infrastructure.

When fully operational, these plants will generate totally green energy for 10.8 GW per year, significantly contributing to EU directives for a decarbonised Italian electricity system by 2035.

If you are interested in learning directly about the services that we can provide as a General Contractor, from energy audits to factory energy diagnostics, turnkey installation of rooftop photovoltaic systems, zero-cost operating leases in the first years of operation, and industrial storage systems, combined with photovoltaic systems, CONTACT US.

Our technical team is operational in the national territory to respond to all your needs.

Technical area and plant design.

When we talk about building a photovoltaic system, we refer to the technical area, and everything generally starts with the customer's request for sizing according to his consumption.

We usually carry out an inspection at the customer's premises and, if possible, also on the roof, to understand how it is set up, studying any critical issues, locating the premises with the electrical panels and the delivery cabin.

When you carry out an inspection on a roof, you already have an idea of what the photovoltaic system will be like and the problems that you will have to face.

When, on the other hand, it is not possible to go to the roof at first, we proceed with a request to the customer for technical documents on the building and photographs of the roof.

 

 

 

 

 

 

Sometimes it can also happen that the customer does not have the DWG drawings of the building or photographs of the roof, so in a preliminary phase the technical team relies on the Google earth software.

Google earth doesn't have absolute accuracy, but it provides a good starting point for creating a floor plan with a certain degree of accuracy compared to reality.

 

Project phases and types of roofing.

In a more advanced phase of the study, after the due site inspections, we are going to render the executive planimetry.

In a photovoltaic design on industrial companies we find different types of roofing.

The most common are:

> Double pitched roofs.

> Cup-shaped roofs.

> Shed roofs.

> The barrel roofs.

> Flat roofs.

 

Each of these types has a different arrangement of the photovoltaic modules and the substructure for fixing.

Currently, for the fastening of the photovoltaic modules, we at Inveco use certified aluminum bars that are riveted to the roof (corrugated sheet, sandwich panel) on which the clamps that form the anchorage of the photovoltaic module to the bars are screwed.

 

 

 

 

 

If the roof does not allow the use of fastening with riveted bars, such as for example a flat slab roof, the fastening of the photovoltaic modules takes place through the use of heavy concrete elements (photovoltaic ballasts) resting on the roof which, with their weight , stabilize and contrast the action of atmospheric agents on the photovoltaic modules.

The design of photovoltaic systems must take into account all those problems that can interfere with the correct functioning of the photovoltaic modules and with the possible use of the roof by third parties, such as the fire brigade.

Industrial roofing often comes with various elements that can limit the correct functioning of the photovoltaic system such as:

> Smoke and heat evacuators (EFC).

> Fireplaces.

> Piping.

> Elements for air recirculation and conditioning.

The shadows produced by these elements during the time of day and the change they have during the year are then studied, especially in the winter months, which are more problematic due to the lower height of the sun on the horizon and consequently for the lower production of energy .

Regulations in the study of the photovoltaic system.

Of no less importance are the minimum distances that the photovoltaic system and all the related devices must respect according to the legislation from the elements that can come into contact with flames deriving from fires (Fire Brigade legislation).

In the study of the photovoltaic system, the technical area takes care, already from the stage of arranging the layout of the modules, of the subdivision of the strings or of the modules connected in series to each other.

 

Each inverter, in fact, is divided into a part of the system based on the power of the inverter itself, and is equipped with a certain number of inputs through which all the photovoltaic modules that will belong to that specific inverter are divided.

By doing so, the fitter and the electrician will have a layout with the physical and electrical subdivision of the system.

Also, no less important, is the design of the electrical lines of the system with the paths of the cable trays on the roof, the descent from the roof and the electrical connection works.

In conclusion, designing a photovoltaic system means responding to customer needs by respecting the reference standards, thus creating the best possible technical solution.
