Breaking Down the Real Math Behind a 3kW Solar System in Indore

A plain-English FAQ guide — 2026 pricing & subsidy data

Indore gets roughly 5.2–5.5 hours of strong, usable sunlight every single day — one of the best solar resources

of any major Indian city. Pair that with rising MPPKVVCL electricity tariffs and the PM Surya Ghar central

subsidy, and a 3kW rooftop system genuinely can pay for itself in about 4 to 5 years — then keep saving you

money for the next 20+.

Item Amount

Gross system cost (panels + inverter + structure + wiring + install) ₹1,80,000 – ₹2,20,000

PM Surya Ghar subsidy (fixed for 3kW) − ₹78,000

Net cost you pay ≈ ₹1,10,000 – ₹1,40,000

Why exactly 3kW?

The subsidy is tiered — ₹30,000/kW for the 1st kW, ₹30,000/kW for the 2nd kW,

and ₹18,000 for the 3rd kW — capping at ₹78,000.

Go bigger and you pay more without extra subsidy, so 3kW is the sweet spot for most Indore homes with monthly bills around ₹2,500–₹4,000.

With Indore's 5.2–5.5 peak sun hours/day, a well-installed 3kW system typically produces:

12–15 units (kWh) generated per day
