Solar Panels and Dirt
How do you know your panels are giving you the best return? Are you getting the full, rated output – and the cash benefits?
Overseas studies have shown that without regular heavy rain, you can be losing typically 30% of nominal output - as little as 5 weeks from new.
You shouldn't be surprised: how often do you wash your car windscreen?
Loss of output means buying replacement power off the grid. If you're off-grid, or have storage batteries, you are even more reliant on maintaining the efficiency of your investment.
So: get the dirt off it, and keep the solar profit.
