Solar panels on vineyards are revolutionizing wine production, improving quality and protecting the environment!
A agrivoltaic was already consolidating itself as a great promise both for agriculture and the renewable energy sector. What was not yet known was that this technology could also bring benefits to wine production.
The winery Turn, located in the Puglia region of Italy, has discovered that integrating agrivoltaic energy systems into vineyards not only helps mitigate the effects of climate change, but also delays grape ripening, resulting in a significant improvement in wine quality.
Furthermore, technology has made it possible to grow grape varieties that are not typical of the region, while providing economic and environmental advantages, such as saving water and generating solar energy on the same land where the vines are grown.

An impressive agrivoltaic energy installation
The project is called Vigna Agrivoltaica di Comunità and features 7.770 double-bonded thin-film solar panels. Together, they have an output power of 970 kW.
The solar panels are oriented south at an angle of 28 degrees. They rest on a concrete structure inspired by the pergola typical of Italian vineyards. The vines grow below, protected from the wind and heat waves.
The secret is in the shade. The shade cast by the solar panels delayed Svolta’s harvest by three to four weeks compared to surrounding vineyards, for both white and red grapes.
This year, Vigna Agrivoltaica di Comunità harvested at the end of August, while in other areas it occurred weeks earlier.
How does this affect the quality of wine?
Reduced exposure to sunlight slows down the accumulation of sugars in grapes, which improves the balance between alcohol content and acidity during fermentation. According to Svolta, this allows high-quality wines to be produced without the need for corrective interventions.
The agrivoltaic energy system has improved the plants’ water stress, protected the grapes from extreme weather conditions and reduced wind speed by half compared to open fields. The winery has carried out technical studies that show a reduction in irrigation water consumption of up to 20% and an increase in land yields of between 20% and 60%.
New grape varieties under study
Svolta has grown more than 30 grape varieties, mostly native to Puglia, and expects to discover new surprises in the coming year. The winery plans to produce sparkling wines from white grapes, for which it believes the agrivoltaic power system will be particularly beneficial.
Very interesting in all aspects...wineries are always large areas and suitable for the installation of this level...new times...
The result is an energetic wine lol
Interesting what I just read here, there are many articles on your blog related to this one I just read I liked your blog. Watch movies
