Technology & Performance Notes
Poly is a low-cost legacy technology best suited to budget-constrained ground mounts. At 19.3% module efficiency the JA Solar JAP60S09-345/PR converts 19.3% of incident solar irradiance into DC electricity, putting it in the mainstream efficiency tier for its class. The 177.8 W/m² power density determines how many watts fit on a given roof or field area.
String Sizing & System Notes
When wiring the JA Solar JAP60S09-345/PR into a string:
- Keep the string Voc (temperature-corrected to the coldest expected cell temperature) below the inverter’s maximum DC input voltage.
- Keep the string operating Vmp within the inverter’s MPPT window across the expected temperature range.
- Size fusing and conductors against Isc (10.9 A) with the standard 1.25x safety factor.
