1. Solar Panels and Clouds: Solar panels can generate electricity even on cloudy days. They still absorb sunlight, albeit less intensely than on sunny days. 2. Effect on Energy Production: Cloud cover reduces direct sunlight, affecting energy output.
The key factor is the amount of direct sunlight that the solar panels receive. On cloudy days, this amount is reduced, leading to lower efficiency. Various weather elements, including cloud cover, significantly influence solar panel electricity generation.
Despite the reduction in efficiency, solar panels can still contribute to reducing household energy bills, even on the cloudiest of days. Solar panels can produce up to 67% less electricity on heavily overcast days compared to sunny conditions.
The Edge-of-Cloud Effect can temporarily enhance solar panel output on partially cloudy days, while rain can improve efficiency by cleaning the panels. Choosing high-efficiency monocrystalline solar panels is advisable for optimal performance in cloudy climates, as they outclass polycrystalline panels under these conditions.
High efficiency panels make more energy than conventional panels on a cloudy day, making them an excellent fit for cloudy climates or if trees partially shade your roof during certain times of day. But don’t forget about the cells themselves.
Storing solar energy for use on cloudy days maximises the benefits of solar power. Solar batteries and net metering are two effective methods for storing surplus solar energy produced during sunny conditions. These storage solutions ensure a steady supply of energy, even when direct sunlight is scarce.
