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.
Rebates and incentives from the government are a great way to help your solar panels more affordable. The initial cost of getting a solar power system set up can be overwhelming, but you can frequently find financial help. Do your research and you may find great programs that offer rebates, grants or other incentives to help you get the solar power equipment to get you started. They can help lower costs considerably. It may be possible to get tax deductions for your costs.
