Why can the performance of a solar PV installation drop in summer?

💬There’s a widespread myth that the hotter it is, the better a solar panel performs. That’s not true ❌. Excessive heat can reduce a solar panel’s performance. However, this negative effect is offset by the extra sunlight in summer🕣☀️ . Below we explain why solar panel performance can drop in summer👇

• Although panels generate energy from sunlight, high temperatures can work against them. As the ambient temperature rises, solar panel efficiency tends to fall. Excessive heat can adversely affect the electrical conductivity of the materials in solar panels.
• In summer the days are longer and the sun is higher in the sky, which means more hours of solar generation. However, in some regions, too much solar radiation can cause the panels to overheat and reduce their efficiency.
• In summer, dust and dirt often build up on the surface of solar panels. This can reduce the amount of sunlight reaching the panels and lower energy production. That’s why good maintenance of your solar PV installation is so important.
