Solar energy is a reliable and popular type of energy that is used and needed globally. India has followed a positive move in its transition to solar power, and the objective of 20 GW was achieved four years earlier. Therefore, people always get worried when solar panels are not very effective on cloudy days. This blog discusses the performability of solar panels on a cloudy day and includes solar panel producers in India who are improving their technology.
Cloudy Day Performance of Solar Panels
Technically, solar panels produce electricity and are constructed to include photovoltaic cells, which are simply referred to as PVs. Regarding energy generation, it gets weaker on days when the sun is hidden, and fewer rays fall into the panels. However, good-quality panels from eminent solar panel manufacturers are still able to harvest diffused and reflected light. The efficiencies may drop to between 10-25% on clear days, but they can generate between 70-90% of their usual power.
Elements Affecting the Efficiency of Solar Panels
The effectiveness of panels depends on several factors on a cloudy day. The density of the cloud affects the amount of energy that can reach the earth’s surface to generate power. Also, some geographical conditions can promote efficiency. The “cloud edge effect” is the moment when the sun's rays passing through the edge of clouds get concentrated, making more power generation.
Solutions to Mitigate Ways That Lower Efficiency
Good-quality panels from reputed solar panel manufacturers are powerful solutions because of modern energy storage and control. Battery systems consist of over generated solar energy during the daytime and hold the power supply when the days are not so sunny. The other working solution in solar power is net metering; thus, solar panels can feed energy back to the grid and draw power. These solutions ensure that solar power is a constant and assured energy source.
