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.
Before installing solar panels on your roof, check with your home owners association. Some associations have restrictions on what you are allowed to do to the outside of the property, and this might mean solar panels are not an option for you. It is better to have this information up front than to purchase the panels and be forced to remove them at a later time.

Do not clean your solar panels with abrasive chemicals. You should use some lukewarm water, a soft cloth and some biodegradable soap if needed. Clean your panels at least once a month or more frequently if you notice your green energy system is not producing as much power as it should.
