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.
A solar cooker is a device which is used to cook food directly under sun light without using Gas, LPG or electricity. It’s a clean process of outdoor cooking.
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.
