When the sun shines on a solar panel, solar energy is absorbed by individual PV cells. These cells are made from layers of semi-conducting material, most commonly silicon. The PV cells produce an electrical charge as they become energised by the sunlight.

How to Calculate the Surface Area Required by Solar Panels

1 m2 horizontal surface receives peak radiation of 1000 Watts. A 1 m2 solar panel with an efficiency of 18% produces 180 Watts. 190 m2 of solar panels would ideally produce 190 x 180 = 34,200 Watts = 34.2 KW. But inclined solar panels also need some spacing between them so practically you would be generating about half the power or 17.1 KW
