solar panels don't like being hot Indeed, and this touches on the 'Regular cleaning of PV panels is important for ensuring maximum energy production' statement

solar panels don't like being hot Indeed, and this touches on the 'Regular cleaning of PV panels is important for ensuring maximum energy production' statement in a funny way. First of all, while the statement is accurate, I'd say is not too important practically depending on where you live. As our isntallation guys also told us. Our panels seem to do just fine with occasional heavy rainfall to clean them and the loss when they're covered in a thin layer of dust is not worth spending time on. On the other hand, the PV cleaning companies will say that it's super important to clean them. So when my mum got her panels cleaned it went like this: sunny day, panels get hot, efficiency drops. Panels were cleaned with water, temperature drops, cleaners told her 'look how much better it is now'. But after they were gone temperature rose again and efficiency was essentially back to where it was before.
