Solar panels use daylight energy to generate electricity, so panels do not need direct sunlight to work. It is photons in natural daylight which is converted by solar panel cells to produce electricity. Heat has no effect on the production of electricity. The materials in the panels, usually silicon, create an electric current when met with natural daylight and this current is then used as standard electricity within properties. However, still many questions arise how effective solar panels are in cloudy climates when there is no direct sunlight.
Well, it is the daylight and not sunlight. It is true that direct sunlight does provide the best conditions for the panels. However, modern solar panels include concentrators which use a system of lenses and mirrors to maximise any light that does reach the cells. As a result it is estimated that solar panels will be 40% as effective in cloudy weather. That means you will still get significant benefits from solar electricity even if your property doesn’t offer the perfect environment. A recent study by the U.S. Department of Energy has shown that production of electricity by large solar panels on cloudy days fluctuated less than in small panels, so the size of the panels used for your installation is something to keep in mind.
Last but not least, the sun is our most powerful and abundant light source. More sunlight exposure your solar panel gets more charge the battery on your solar lights will receive. As photovoltaic solar panels have become better at converting energy from the sun into electricity and their costs are going down, they are becoming a more common investment for businesses and individuals. Not only it is green energy, but at the same it reduces energy. So if you are looking to install solar panels in your house then please do contact us. We would be happy to help you.
