The most common question we hear on site surveys in Kushinagar is simple: kitna bada system lagega? The answer depends on three things, your monthly electricity bill, your roof space, and your budget after subsidy. Here is the honest comparison.
The quick comparison table
| Factor | 1 kW | 2 kW | 3 kW |
|---|---|---|---|
| Approx. system cost | ₹60,000 | ₹1,20,000 | ₹1,80,000 |
| Total subsidy in UP | ₹45,000 | ₹90,000 | ₹1,08,000 |
| Your effective price | ≈ ₹15,000 | ≈ ₹30,000 | ≈ ₹72,000 |
| Units per month (approx.) | 120 | 240 | 360 |
| Covers a monthly bill of | up to ₹800 | up to ₹1,600 | up to ₹2,400 |
| Shadow-free roof needed | ~100 sq ft | ~200 sq ft | ~300 sq ft |
Prices are indicative for standard on-grid systems and vary with panel brand and structure height. Generation of roughly 120 units per kW per month is a realistic yearly average for eastern UP, higher in summer, lower in monsoon.
When 1 kW makes sense
A 1 kW system suits a small home running lights, fans, TV and a fridge, with a bill under ₹800. The effective price of around ₹15,000 after subsidy makes it the cheapest entry into solar. Its limitation is headroom: add a cooler or a new fridge and you will outgrow it.
When 2 kW makes sense
Two kW fits a typical village or small-town home with a bill between ₹800 and ₹1,600. At roughly ₹30,000 effective cost it is excellent value, because the subsidy covers 75% of the price.
Why 3 kW is the sweet spot for most families
The subsidy structure is designed to make 3 kW the best deal: the central subsidy maxes out at ₹78,000 and the UP state subsidy at ₹30,000, together ₹1,08,000. Around 360 units a month covers almost every normal household, including a cooler, washing machine, and even a small AC used sensibly. The payback is typically under 3 years, and after that the electricity is effectively free for the remaining 20+ years of panel life.
One more advantage: with net metering, extra units in winter get credited against your summer usage, so the bigger system rarely goes to waste.
Should you go even bigger than 3 kW?
Above 3 kW the subsidy stays capped at ₹1,08,000, so every extra kW is at full price, around ₹55,000 to ₹60,000. It still makes sense for large homes, shops and anyone planning an AC or electric vehicle, but the economics are strongest up to 3 kW.
