When considering the purchase of a photovoltaic system, it is essential to inform yourself not only on the technical aspectsbut also on incentives and the Tax breaks available. Renewable energy regulations change frequently, so you should consult official state sources for up-to-date information.
Let’s see in detail what they are technical aspects, cheap And bureaucratic to be evaluated before purchasing a photovoltaic system.
Buying a photovoltaic system: incentives available in 2024
The 110% Superbonus, which included the installation of photovoltaic systems, is no longer in force. Starting in 2024, the incentive was reduced to 70% and is applicable only to condominiums. This means that those who live in a condominium can still benefit from a tax deduction for installing solar panels.
The Restructuring Bonus, which provides a 50% tax deduction, is also available for single residential units. This incentive is distributed in annual installments spread over 10 years. Furthermore, it is possible to take advantage of aVAT reduced at 10% for existing homes And 4% for new buildings which involve energy saving works. This applies not only to a photovoltaic system, but also to storage batteries.
The Net Metering (SSP) is progressively leaving room for Dedicated Withdrawal (RID) starting from 2024. The RID, managed by the Energy Services Manager (GSE), allows the producer to sell the energy fed into the grid. This regime is an alternative to selling on the free market, which is more complex and less convenient for small producers.
The RID provides two remuneration mechanisms: i Guaranteed Minimum Prices (PMG) and the Hourly Zonal Price (PO). The PO is variable and not established a priori, however the PMG is usually established every year.
Guarantees on the components of the photovoltaic system
THE photovoltaic modules I am guaranteed both for factory defects (generally 10 years) both for the production (often 25 years or more), with a warranty covering a annual power loss (usually 0.7% per year).
It is important to read the warranty conditions carefully and consider all variables, such as resistance to wind and snow.
The inverter, crucial for the operation of the system, have guarantees ranging from 3 to 5 years, often extendable to 10 years. Some companies offer extended warranties at the time of purchase, so it’s a good idea to explore these options.
The optimizerswhich improve the efficiency of the system, usually have guarantees of around 25 years.
The batterieswhich store energy, are guaranteed for 5-10 years, but their life can be extended with correct maintenance.
Other electrical componentsunless otherwise specified, has a 2 year warranty.
Insurance policies
Given the exposure to atmospheric agents, it is advisable to take out a insurance policy that covers the entire photovoltaic system against damage from hail, wind and other natural events.
Many home policies can be extended to include the photovoltaic system. It is essential to carefully read the terms of the insurance, including the deductibles and the exclusions.
Bureaucracy and administrative practices: simplified, ordinary process and additional practices
The bureaucratic procedure for installing a photovoltaic system can vary. In many cases, it falls into thesimplified process which involves filling out two forms on the local distributor’s portal. The first module it’s very quick, you enter your personal data and some data on the system and the start date of the work. Once the system is finished, complete with self-test and tested, the form can be filled out and forwarded.attachment twowhich includes the operating regulations with all attachments and the completion date of the works.
In some cases, a ordinary process more complex than involves a connection question and further procedures at the Terna portal (GAUDÌ) for the census of the plant. Next, you will need one practice at the GSE for on-site exchange or dedicated collection, in addition to ENEA practice to obtain energy incentives.
