Can anybody tell me the power supply of the home solar cell?
Hard to say, because you didn't mention how many electrical home appliances you are going to run in one time at home. Nobody would be able to give you a right answer.
Since the power supply of two solar cells panel would be below
500 watts, so if you are not using too much euipment at home at one time, you won't be needing more than 250WATTS
l can give you an example as following: 40W * 4H=160Wh=0.16 degree power
In accordance with the summer sunny weather one day 5 standard sun, consider 70% system efficiency
160 / 5 / 70%=45.7W, so 50 Watt Solar cell is enough.
You should first look at your situation, and see how much equipment you are running. Then you can decide the power supply of the solar cells at home.
In my old place, all I was using was the 50WAT solar cells, which is definitely good and useful for all my daily use.
