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.
I explain how much this system cost and I go over the site plan and electrical diagram in this link https://youtube.com/watch?v=TFwdY0wiBGA Keep in mind …
Keep in mind that purchasing a solar power system often enables you to receive tax credits from the government. You may find that you get back as much as 30 percent of the total cost of your system. So, if you look into a system and think that it costs too much, investigate whether or not you will get credit back to determine how affordable it actually is.
The amount of electricity you generate from solar panels is dependent on how many panels you install and the efficiency of these panels. You will need to do a little math to calculate the number of panels you will need. Higher-efficiency panels are often your best bet cost-wise.
