Photovoltaic (PV) solar panels may generate electricity from both direct and indirect sunlight. This implies they can continue to work even if the sun is unavailable. Solar panels, on the other hand, are most efficient and productive when exposed to direct sunlight on bright days.
Solar panels will continue to perform even if light is reflected or partially obscured by clouds, but their energy production capacity will be reduced. On days when there is a lot of cloud cover, solar panels will yield up to 25% of their regular power production.
Rain is normally associated with clouds, and here’s something you might not know: rain actually aids the efficiency of solar panels. Rain wipes away any debris or dust that has accumulated on your panels, allowing them to absorb sunlight more efficiently.

How efficient are solar panels on cloudy days?
On overcast days, you may anticipate your solar panels to perform at 10 to 25% efficiency, depending on the panels.
How do solar panels work when there is no sun?
Solar panels will not operate if there is no sunshine (for example, at night). This is due to the fact that the photovoltaic effect, which is the mechanism by which solar panels turn sunlight into electricity, requires some light to convert.
However, solar panels may work with indirect light, which means they can work even if the sun is blocked by clouds. You also may be able to use solar electricity that has been saved in a solar battery system.
Do solar panels work on snowy days?
On snowy days, solar panels will not perform at their greatest efficiency because of cloud cover and less sunshine. The snow, on the other hand, is typically not an issue, especially since a sprinkling of snow is readily blown away by the wind.
Snow will only obstruct your solar panels if the snowfall is so heavy that the panels are totally covered, or if the weight of the snow threatens the structural integrity of your solar panels.
Even if the effectiveness of your solar panels is reduced on cloudy days, you’ll still be able to generate some power.
