More and more people and companies are deciding to equip themselves with roof-mounted photovoltaic systems to save on their utility bills and participate in the decarbonisation. There is a lot of enthusiasm for this green technology, but enthusiasm is sometimes dampened when one learns about the Italian regulations on the installation of photovoltaic panels.

The installation of photovoltaic systems has seen increasing regulatory attention in recent years, reflecting the importance of environmental sustainability and renewable energy. However, regulations can seem complex and varied, and knowing the up-to-date requirements is crucial for anyone considering the installation of a photovoltaic system.

In Italy, The installation of solar panels generally falls under the free building regime, exempting many interventions from specific building authorisations. However, there are some significant exceptions that deserve special attention.

Therefore, we decided to produce this article, a short guide to the Italian regulations on the installation of roof-mounted photovoltaic panels.

Reference Standards for Photovoltaic Installation

As we have mentioned, in most cases, no building permits need to be obtained or the commencement of works notified. However, there are specific limitations when it comes to areas of special historical and environmental value. The installation of photovoltaic systems is regulated by a series of regulations governing its approval and execution. The main regulations include the Free Building Glossary of 2018, Law Decree 17/2022, and Legislative Decree 42/2004.

The Free Building Glossary states that photovoltaic systems fall under free building works, which means that in many cases, a specific building permit is not required for the installation of photovoltaic panels on existing buildings. However, this simplification only applies if the panels do not substantially change the appearance of the building.

Decree Law 17/2022, known as the Bills Decree, further simplified the procedure, considering it ordinary maintenance and therefore exempt from administrative permits for most installations. This decree introduced Article 9, which allows the installation of photovoltaic systems without the need for specific permits, with exceptions for cultural heritage and landscapes of special value.

Simplifications and Single Installation Model

The simplification decree introduced the Simplified Single Form for the installation of photovoltaic systems. This model is intended to facilitate the start of work and reduce bureaucracy, especially for installations with a capacity of 200 kW or less.

To use this template, the applicant must fill in the form and send it by email to the relevant grid operator. Once the application has been verified, the permit is automatically granted if the requirements are met, making the installation of new panels more accessible and less bureaucratic.

Regulations for Landscaped Areas

Not all areas are equal when it comes to the installation of photovoltaic systems. In particular, areas subject to landscape or historical constraints have more stringent regulations. Legislative Decree 42/2004, known as the Cultural Heritage and Landscape Code, stipulates that specific permits must be obtained for systems installed in such areas. The Ministerial Decree of 2 April 1968 also imposes additional restrictions for the installation of photovoltaic systems within urban agglomerations of historical, artistic and environmentally valuable character, such as historic centres.

Installations in historic or particularly valuable areas may be subject to additional restrictions. In these cases, the compatibility of the panels with the landscape must be carefully assessed, and the installation can only be authorised if the panels are integrated in such a way that they are as unobtrusive as possible. The regulations require a Certified Declaration of Start of Activity (SCIA) to ensure compliance with landscape regulations.

CEI Standards and Plant Safety

CEI standards provide detailed guidelines to ensure the safety and efficiency of photovoltaic installations. Among the main CEI standards are CEI EN 61215 and CEI EN 61730, which deal with the certification of photovoltaic modules and safety standards for installation, respectively.

• CEI EN 61215 is essential to ensure that photovoltaic modules comply with performance and reliability standards
• CEI EN 61730 sets out safety requirements to prevent electrical and mechanical hazards when using the system
• CEI EN 62108 regulates the qualification and authorisation of concentrating photovoltaic module and system designs, ensuring that these technologies are safe and perform well.

Challenges and Alternatives: When Photovoltaics is Not Possible

Not everyone can afford to install photovoltaic systems due to regulatory, economic or structural constraints. Stringent regulations, especially in areas of landscape or historical value, can make the installation of solar panels difficult or impossible.

For those faced with these limitations, an interesting alternative is the Heiwit. One HEIWIT token is equivalent to 100 watts of installed power of a large industrial photovoltaic system. Each token is a share of the energy produced by a plant that is connected to the grid and has a duration of 30 years. During this period, token holders share in the economic benefits generated by the system in proportion to their share.

For example, a single HEIWIT token produces around 120 kWh of energy annually, contributing to a significant reduction in CO2 emissions of 63 kg per year. Buying a HEIWIT token means having a small part of a large solar plant, benefiting from both the energy production and the profits derived from it.

Conclusions

Although photovoltaic installation regulations may seem complex, a good knowledge of the laws and procedures can greatly facilitate the process. It is important to stay up-to-date on the latest regulations and Evaluate innovative alternatives such as our Heiwit tokens when regulatory or structural conditions do not allow the traditional installation of photovoltaic panels.

By purchasing HEIWIT tokens, you not only contribute to environmental sustainability, you also get a financial return. Each token, once purchased and placed in your HEIWIT energy wallet, starts producing energy immediately. The proceeds from energy production are used to lower your household bill. If every Italian bought 9 HEIWIT tokens, we would cover 100% of national consumption with renewables. This goal, although ambitious, shows how much we can contribute significantly to the energy transition.

The transition to renewable energy sources is a challenge of our time and you too can contribute significantly. Find out more on our website.
