It is no longer a race to see who installs the most kilowatts. After the era of enthusiasm and incentives, Italian photovoltaics is entering a phase of maturity: today, what makes the difference is not how much is installed, but how systems are designed, managed, and maintained. This is the season of expertise, quality, and an integrated supply chain — the same logic that is transforming the entire plant engineering sector. According to Terna, as of September 30, 2025, more than two million photovoltaic systems are connected in Italy, with a cumulative capacity of 41.1 gigawatts. Compared to the end of 2024, this represents a 9% increase in the number of installations and an 11% increase in capacity. These are solid figures, but they also indicate a slowdown compared to the previous two years: in the first six months of 2025, new installations decreased by 15.9% compared to the same period in 2024. The sector, however, is not stopping — it is simply changing direction. The new phase of photovoltaics is measured by the quality of installations, their integration with the grid, and their ability to operate for years with stable and predictable performance. This marks a shift from an economy of quantity to an economy of expertise. Skilled designers are needed to assess exposure and shading, technicians specialized in inverters and storage systems, and maintenance professionals who understand long-term performance dynamics. Photovoltaics is no longer an improvised trade: it is an industrial sector with rules, responsibilities, and profit margins that are moving from installation toward long-term management. Read more

A chase for the sun, that of Massimo Alfredo Lauria, which led him to leave his career as a surveyor to first become the general director of a security institute and then co-founder and CEO of the Tresun group, an Italian excellence in the utility-scale photovoltaic sector founded in 2014, which today has almost 200 employees, with a turnover of several million euros.

Lauria, how was Tresun's growth journey?
Mystical and glorious, as it all started from the economic hardship of three former colleagues, now partners, who had not received their salary for eight months. We were in great financial difficulty and had families, but we also had an immense drive and a project to follow. This was crucial. That’s why I always say, especially to young people: take a pen and paper, write, and plan your future. It wasn’t easy, but I must say it was, has been, and will be our destiny. I had and still have a clear and determined mission, Read more...
