Attempt to avoid a panel with high STC or factory-rating, however a reduced NOCT or everyday score, family member to an additional panel. as listed by the supplier, e.g. 250 watt solar panel is qualified of producing maximum 250 watt continuously under optimal Common Test Problems.


STC irradiance at 1000 W per square meter, cell temperature at 77F (25C), air mass AM 1.5. according to PVUSA examination conditions, e.g. a 250 watt STC component may produce optimal 225 watts in PTC real-world problems. PTC Peak Watts are the REAL-WORLD rated MAXIMUM DC power created under PVUSA Examination Conditions for sunlight and temperature.

according to day-to-day conditions, e.g (Jackery Solar Kits). a 250 watt STC module might create 195 watts in NOCT problems. Nominal Watts are the AVERAGE constant DC power generated in daily problems for sunlight and temperature. NOCT irradiance at 800 W per square meter, ambient temperature level at 68F (20C), solar cell temperature level at 113F (45C), wind rate 2 mph


A greater % is much better, however be certain to balance that with the price of the panel. Many basic photovoltaic panels have performance from 14% to 20%.
