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