Always use non abrasive cleansers on your solar panels. An abrasive cleaner can scratch the surface of the panel and cause permanent damage and affect how well the solar panel works. There are commercial cleaning solutions to use or you can use a pool skimmer with a very soft cloth on it.
Use winter sunshine hours instead of summer hours whenever you are calculating how many solar panels you will need. This is because winter sunshine hours only add up to about half that of summer. It is better to overestimate how many panels you will need rather than underestimate. If you underestimate, you will end up losing power when you need it.
I show you how to make eclipse glasses protectors out of paper plates and elastic, so the little ones are fully protected from the eclipse rays!
Do the math prior to investing in solar power. Not every location is a good bet to deliver energy savings. The best option is to look into the costs and the potential earnings (based off your sun conditions) to see what the costs will really be like. Sometimes, it'll be way more costly to use solar.
