We have measurement scales for every element. For example, if we have to buy milk, we have measuring scale called liter, if we want to buy sugar, we have measuring scale kilogram. But the question arises that what will be an appropriate measure of a solar panel?

Now we are interested in the amount of electricity a panel produces. However, panels output depends upon the amount of light strike it. Through this method a panel is classified according to the electricity produced under these condition. The measurement is expressed as watts peak (Wp).

In order to get cost per watts peak, we have to divide cost of the panel by its power output. So the cost per watt peak is only one factor in determining the total cost of a photovoltaic system.
