2025 is a decisive year for the growth and spread of solar energy in Italy, with new opportunities and incentives increasingly pushing families and businesses towards this sustainable choice.
With the rising cost of energy and increasing focus on the ecological transition, photovoltaic systems e solar thermal represent increasingly sought-after solutions.
According to the GSE Statistical Report 2023, in Italy over 21.7% of thermal energy demand is already covered by renewable sources, confirming a steady growth trend that attests to the increasingly central role of clean energy in the national energy strategy.

How a photovoltaic system works and why it's worthwhile
A photovoltaic system transform directly the sunlight at electricity. The photovoltaic modules, installed on the roof or on dedicated structures, capture sunlight and convert it into direct current, which is then transformed into alternating current by the inverter, making it available for domestic or business use.
Today, thanks to the integration of storage systems (battery), is it possible to store the energy produced during sunny hours to use it in the evening or during times of low solar radiation, further increasing the’energy autonomy and the saving.
A residential photovoltaic system is paid back on average in 5-7 years thanks to Savings on your bill and to tax incentives active. On average, a home with an installation of 3 kilowatts can save about 500-700 euros per year on electricity costs, with a further increase of saving if paired with a storage system.
How a solar thermal system works and its advantages
The solar thermal, instead, exploits the’solar energy to produce domestic hot water and, in some cases, even support the domestic heating system. Solar thermal panels, also known as solar collectors, capture the heat radiated by the sun and transfer it to a heat transfer fluid, which then heats the water for domestic use.
There are mainly two types of solar thermal systems:
- Natural circulation systems: simpler and less expensive, they operate on the physical principle of the density difference between hot and cold water. They are ideal for homes located in mild climate zones and for uses that do not require large volumes of hot water.
- Forced circulation systems: more complex and efficient, they use a pump to circulate the heat transfer fluid. They are also suitable for cold climates, large homes, or when there are particularly high hot water demands.
A well-sized solar thermal system can cover up to 70% of a family's annual hot water needs, significantly reducing energy consumption related to water heating and ensuring significant long-term economic savings.
Photovoltaic and solar thermal incentives 2025: what they are and how they work
2025 brings with it the confirmation of significant benefits for those who choose to invest in solar energy, making it the ideal time to make a sustainable and advantageous choice.
Among the main opportunities available are:
- Tax deduction of 50% for the installation of domestic photovoltaic systems, through the Home Bonus.
- Conto Termico 3.0 for solar thermal, which offers contributions up to 65% of the expenses incurred for the installation of domestic hot water production systems from renewable sources.
These measures, combined with the energy savings guaranteed by the systems, make 2025 a unique opportunity to invest in renewable sources and improve the efficiency of your home.

Italian Solar Market Trends: Updated Data
According to the data GSE 2023, the number of photovoltaic installations in Italy has grown by 17% compared with the previous year, with a strong boost from the residential segment under 20 kW, which represents a full 94% of the total. This is a fact that confirms the growing attention of Italian families toward self-production of energy from renewable sources. Solar thermal also continues to record constant growth, albeit with smaller numbers, supported by available incentives and the need to reduce domestic gas consumption.
Additionally, according to the SolarPower Europe 2024 Report, Italy confirms itself among the top five European markets for new photovoltaic installations, a sign of increasing interest in solar energy.

How much can you save with a photovoltaic or solar thermal system?
Choosing a photovoltaic or solar thermal system isn't just a sustainable choice, but also a way to achieve concrete savings on your bills.
With a residential photovoltaic system you can reduce your electricity bill by up to 60%, while with a solar thermal system can gas consumption for domestic hot water be reduced by a value between 30% and 70%.
A practical example?
A typical home in Umbria with a photovoltaic system of 4.5 kW can achieve an average annual saving of approximately 900 €.
But the benefits don't stop there: investing in solar also means increase real estate value of their home (with estimated increases between 5% and 10%), reduce CO₂ emissions. a medium-sized photovoltaic system avoids approximately 1.200 kg of CO₂ the year) and improve energy independence, while protecting themselves from gas and electricity price fluctuations.
