For better savings on your utility bill, keep your solar panels clean. Solar panels are practically silent and since you don't touch them, you can easily forget them. The cleaner their glass panels are, the more clear surface area the sun has to "work with." There's no set amount of time that you should clean them. If you live in an area with lots of wind, dust or construction, they may need cleaned frequently. Some ares may require weekly cleanings.
Don't assume that you have to live in the desert to use solar panels on your roof. If your roof expanse gets a minimum of five hours of direct sunlight on an average day, there is likely a solar panel installation that can generate electricity for your home or building.
