Solar panels do not generate power at night. The Photovoltaic (PV) effect relies on sunlight to make power. Once the sun goes down, your home or business will start to draw power from the main grid as usual. This process is seamless – your energy supply is never interrupted.
What are the best weather conditions for solar power?
Solar panels still work on a cloudy day; however they will not generate as much electricity as when the weather is clear and sunny. The best weather conditions for solar panels to run effectively are when it’s very sunny, but also cool. Heat does not help solar panels at all! Typically the best temperature for a solar panel to be is around 25 degrees. But in Australia, especially in the summer months, solar panels can get up to 65 degrees. This has a noticeable impact on the solar panel performance.
