-- The solar array is an assembly of panels into a powerful array |
K |
2 |
-- The assembly can deliver more energy than the individual panel because |
|
3 |
-- of the transformer unit which converts the panel output variations into |
|
4 |
-- a stable supply. |
|
5 |
-- Solar arrays are not able to store large amounts of energy. |
|
6 |
-- The LV arrays are used to make medium voltage arrays. |
