On-grid · net-billing
Cheapest solar. Also the one that goes dark with WAPDA.
Huawei SUN2000, Growatt MIN, Solis. No battery. Anti-islanding is a safety law, not a defect. After 9 Feb 2026 you sell leftover kWh at ~Rs 11.
RIGHT FOR
Day factories + genset
Motors already have diesel. PV cuts daytime units. Export is a bonus. Industry.
RIGHT FOR
Offices with reliable feeders

WRONG FOR
Houses with night shed
Fans at 2 a.m. need hybrid + LFP. On-grid plus a UPS is two boxes doing a worse job than one hybrid.
