Solar Panel Ratings Explained
On the other hand, the Short Circuit Current rating (Isc) on a solar panel, as the name suggests, indicates the amount of current produced by the solar panel when it''s short-circuited. The Isc rating represents the maximum amount of current the solar panel could potentially generate under the Standard Testing Conditions.
