The eleccity is then converted to alternating contert (AC) by an incorrrr, making it usable for homes, esses, and thee grid.

Arrays can mounted on dachtops, grounducted on tracking systems, or integrated into building materials such as solar shingles. The capacity of a solar array ranges from a few kilowatts for a residential system to hundreds of megawatts for large solar farms.
