P/M = polycrystalline or moncrystalline

Area = area of solar module on a square foot basis. Usually corresponds with weight.
STC = standard testing conditions. Manufacturers internally test their own solar modules. STC specifies a temperature of 25°C (77 F), solar irradiance of 1000 W/m2 and an air mass 1.5 (AM1.5) spectrums.

PTC = PV USA Test Conditions.The PTC rating is an independent measure of a module's efficiency. PTC ratings are 1,000 watts/m2, 20 degrees ºC (68ºF), and wind speeds of 1 meter per second at 10 meters above ground level.

PTC/STC = this value represents the approximate energy output comparing the STC (name plated output) to the PTC tested conditions. In general, the higher the percentage the total energy output will be higher

Pwr Tol = power tolerance of solar modules, modules will perform based on tolerance value ± STC value
