STC, PTC, NOCT: What do they mean and how to use them?

STC is used by solar panel manufacturers to test and rate their panels. The value that interests us is the maximum power (P max) or rated power (P r), which is the nominal power of a solar panel when you look to buy one. It could also be called peak power. In a specification sheet, it''s always indicated in a section with STC nominated nearby.
