Commercial Solar Calculator — Delhi NCR
Production and savings estimate for a commercial/C&I solar plant in Delhi NCR — 10 kW to 2 MW, local irradiance and tariffs.
Commercial rooftops in Delhi NCR pay commercial tariffs — usually higher than residential — which is why C&I solar is often the fastest-payback segment. Delhi rooftops fight dust and winter smog — soiling losses run higher than the Indian average, so monthly cleaning is worth real money; DERC net-metering remains generous. Defaults below reflect a typical 100 kW commercial array; scale to your roof and check the monthly table against your facility's load profile.
With your numbers: 100 kW × 5 kWh/m²/day × 365 × 1.10 (plane-of-array) × 82% PR = 163,805 kWh/year. First-year figure — subtract ~0.5%/yr panel degradation for later years.
Indicative estimates only, not financial or investment advice. Tariffs, subsidies and net-metering rules change — verify with your DISCOM, utility or installer before committing.

Frequently asked questions
How accurate is the Commercial Solar Calculator — Delhi NCR?+
It uses the same physics as NREL's PVWatts: irradiance × plane-of-array factor × performance ratio. With honest inputs, expect results within ±10% of a professional simulation — good enough for sizing and payback decisions. For bankable projects, follow up with site-measured data and a full TMY simulation.
What is specific yield and what's a good value?+
Specific yield is annual kWh produced per kW of panels. It removes system size from the comparison: 1,400–1,700 kWh/kWp is typical across sunny India, 950–1,100 in Germany or the UK. If a quote promises far above the regional norm, question the assumptions.
Why is my real output lower than the calculator says?+
The usual suspects in order: more shading than assumed, dust (soiling can cost 5–15% where cleaning is irregular), inverter undersizing/clipping, and higher cell temperatures than the default loss stack assumes. Compare measured monthly output against the table here to localize the gap.
Does panel direction matter as much as size?+
Orientation typically moves output 5–25%. Equator-facing at near-latitude tilt is ideal; east/west roofs lose roughly 10–20% but spread generation across the day, which can be worth more under time-of-use tariffs or self-consumption rules.
