How much does the efficiency change when a solar panel is wet?

John,
I haven't seen anything that suggests any significant decrease in efficiency from water droplets, since the panels are coated with glass. The light may refract when passing through the droplets, but they may also act as a lens as well. I could see a decrease in efficiency from snow though, because its high reflectivity index would cause more light to reflect back into space (as is the case at the poles) and make it more difficult
for light to penetrate into the panel.
Hope this helps.

I'll also add on that solar panels are rated for maximum efficiency on a clear sunny day. If they are wet, it might mean there is cloud cover which will have an effect on the efficiency anyhow. If they're wet and it's sunny, they would probably dry up quickly enough so there would not be any significant effect.

We are considering an off grid solar system for our home. We live in Liberia west Africa and we have 6 months of Rainy Season (April -Oct) and 6 months of Dry season (Nov-April). We are looking at 12-120watts panels or 10-130 watts panels. We want to use 24 volt batteries but don't know how many we would need to run our system. I am very new to solar power (Novice) and could use all the advise and info I can get my hands on. Most of what I know about solar power I have read on the net or spoken to a few friends who also live in Liberia and uses solar power. There is no Gov't power here due to the 15 yr Civil unrest in the Country. All advise .
