Do Solar Panels Work During Rain?

It’s quite obvious that if you’re planning to invest in a solar system, one of your first questions will be; do solar panels work during rain? 

With the incredible growth of the solar industry in Cape Town specifically, it’s natural to want to know what will happen with your investment when the winter rains head in.

One of the most important things to take into account is the quality of the PV (Photovoltaic) solar panels you choose to invest in, since this is one of the main contributors in making sure you have a fantastic ROI when you invest in a PV solar system.

If there’s one team of solar experts you can rely on to be absolutely honest with you about anything to do with solar energy, it’s the Renaissance Solar team in Cape Town!

But, back to the original question and a few basic answers to it, without getting too technical! 

Do solar panels work during rain?

According to, “Photovoltaic panels can use direct or indirect sunlight to generate power, though they are most effective in direct sunlight. Solar panels will still work even when the light is reflected or partially blocked by clouds. Rain actually helps to keep your panels operating efficiently by washing away any dust or dirt.”

Granted, Solar Energy Industries Association (SEIA) is an American association, but isn’t this just great news anyway, especially when it comes to living in the higher winter rainfall areas in Cape Town?

It would be best to chat to the team at Renaissance Solar about exact data and percentages when it comes to how well solar panels work during rain, but on average, PV solar panels are able to produce anything from between 10 to 25% of their optimal capacity to generate electricity.

Although solar panels perform best with direct sunlight, they can still operate through indirect sunlight, otherwise known as radiation. In any event, a really good storm keeps your PV solar panels operating beautifully, because of the sheer cleaning power of the storm!

Once you own a PV solar system or a solar hot water system, you’ll wonder why it took you so long to make the change! Nothing can stop the effect that load shedding has on every life in South Africa, except for our beautiful sun!

Consider that Europe and other far colder climates are way ahead of us in terms of relying on solar energy, and you’ll have the answer to the question of whether or not solar panels work during the rain.
