| ede397 | 1 | -- The medium voltage solar array is an assembly of low voltage arrays. |
| K | 2 | -- The assembly can deliver medium voltage levels and is a 10% less efficient |
| 3 | -- compared to 5 individual low voltage arrays due to losses in the transformer. | |
| 4 | -- However medium voltage is supplied. | |
| 5 | -- Solar arrays are not able to store large amounts of energy. | |
| 6 | -- The MV arrays are used to make high voltage arrays. | |
