| 8e03d7 | 1 | -- The solar array is an assembly of panels into a powerful array |
| R | 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. | |
