How many solar cells are required to produce a power of about 6-7kw(kilo watts)?.?
Question:
-thank you
Answer:
It depends on the amount of solar flux your panel has falling on it and the efficiency of your panel.
I'm assuming that you mean photovoltaic panels
At high noon, you may get a flux 1100 W/m^2 on your panel, other times of the day, may be significantly less. You can design a tracking mount, whic will help keep the sunlight incidence angle normal to your panel.
The panel itself, depending on design will have an efficiency of 12-25%., so, for best case (high noon on a sunny day, 25% efficient panels), peak output, you're looking at a cell area of about 24 m^2 to get 6.5kW
How many cells it takes to cover that area depends on the dimensions of the individual cells. The panels themselves may be larger since the space between the cells and subpanels will likely not be zero.
Your cell efficiency will also vary with temerature, humidity, cleanliness of the panels and other factors.
each solor panel is rated different , this question has no answer, i have some cheap solar panels 15watts , 1amp per hour for about $145 , anyway 6kw would take a hell of alot of panels
Try here, last paragraph. They claim 1Kw for 100 Sq feet of their sunslates.
