Solar energy potential in Valls

As we well know, the same amount of photovoltaic energy is not produced in the north of Europe as in the south of the continent, and Valls in Tarragona is a privileged city and municipality thanks to the number of hours of sunshine (2,620) and the high solar irradiation of the province of approximately 5.59 kWh/m2 of Peak Solar Hour. This results in a high production of photovoltaic energy from homes and companies and therefore their solar energy potential.
