It is possible to produce energy from mW to MW using solar photovoltaic cells.

Explanation

Solar panels can be constructed by connecting solar photovoltaic cells in either series or in parallels. The combination are done in such a way that it can give the desired potential difference and the current. Siakr strings are then made by joining solar panels in a series. When solar strings are joined in parallel, they form solar array. Therefore, by proper combinations, it becomes possible to produce energy from mW to MW using solar photovoltaic cells.
