Solar power plants use two main types of technology: Photovoltaic (PV) systems use solar panels. These panels can be on rooftops or in large solar farms on the ground. They change sunlight directly into electric power.
You may wonder how hot solar panels get on a summer day. In many places, the surface temperature can reach 60°C (140°F) or even higher. When this happens, you will notice your system makes less electricity.
Most solar panels operate most efficiently around 77°F (25°C), but on hot summer days, surface temperatures can exceed 150°F (65°C). While your system still generates energy, extreme heat can slightly reduce efficiency during peak afternoon hours.
During peak summer months (July to August), your solar panels will typically produce the most energy. As we move into the colder seasons, production can decrease by 40-60%, especially in areas that see more cloudy days.
Ideal temperatures range from 50°F to 85°F (10°C to 30°C). If batteries become too hot, consider using insulation to buffer against temperature spikes.
More solar power is produced in the summer than any other time - regardless of how hot it gets. That is why peak power output generally occurs at midday in April or May.
