Sizing Solar PV for Farm, Cold Room and Polyhouse Loads
Size for daily energy demand (kWh/day) not peak load. Use 4.5–5.0 kWh per kW per day in most of India as the generation benchmark.
1-acre NVPH with fertigation: 3–5 kW rooftop or ground-mount, ~15–20 kWh/day. The pump can be covered under PM-KUSUM — Component B for a standalone off-grid solar pump, Component C for solarising an existing grid-connected pump.
100 MT cold storage: 25–40 kW depending on insulation quality. Net-metering connected on industrial tariff slashes the power bill 50–80% with 3–5 year payback.
5 TPD food processing unit: 75–150 kW depending on motor mix. Best designed with synchronous-grid net-metering plus diesel-backup; standalone hybrid only for genuinely off-grid sites.
