Be prepared to keep your solar panels clean. The dirtier they get, the less efficient they are at generating power. While it is true that rain and wind can often take care of a lot of this for you, you do need to get up there sometimes and dust them off yourself.
There is really no reason to even consider getting a solar energy system if you live in an area that rarely sees the sun. This does not mean that a less than reputable company will not try to sell you a solar system though. If your roof does not receive at least 6 hours of full sunlight per day, you should not consider solar power.
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 …
Solar cells can cost more than other alternatives. Get a professional to perform an energy audit on your home. This can help you find the ways you waste energy so you can change them. By making these changes, you may not need to install as many panels.
Maximize the output of your solar panels by adjusting them seasonally. Adjusting your panels twice a year, once in the summer and once in the winter, will ensure that your panels are producing the maximum amount of energy by taking into account the earth's changing position relative to the sun.
