Commercial Solar Payback — Maharashtra
Payback and 25-year ROI for a C&I solar investment in Maharashtra, with self-consumption share and export rates.
For a business in Maharashtra, solar competes with the commercial grid tariff — and usually wins. Commercial plants self-consume 80–95% of production (daytime load), so the retail rate, not the export rate, drives the result. Maharashtra's high commercial and residential tariffs (among India's steepest) mean every solar kWh offsets expensive grid power — payback beats sunnier but cheaper-tariff states. Indian C&I buyers should also weigh accelerated depreciation (40%) which this simple-payback view doesn't include.
Payback = net cost ₹4,125,000 ÷ yearly savings ₹1,509,293 = 2.7 years. Tariff inflation shortens it; loan interest lengthens it.

Frequently asked questions
What payback period is realistic for solar?+
With current equipment prices: 3–6 years for most Indian homes (faster with subsidies and high tariffs), 3–5 years for commercial systems with high self-consumption, 6–12 years in low-tariff or low-sun markets. Anything under 8 years implies a 12%+ tax-free return — far better than most fixed-income options.
Why does self-consumption share matter so much?+
Energy you use directly offsets the full retail tariff; energy you export usually earns much less (feed-in or APPC rates). A system self-consuming 80% can pay back twice as fast as the identical system exporting 80%. Size to your daytime load, not to your roof area.
Does the Commercial Solar Payback — Maharashtra include maintenance costs?+
Yes — it reserves 1% of system cost per year, covering cleaning, an inverter replacement around year 10–12, and minor repairs. It also derates lifetime ROI for 0.5%/yr panel degradation, which most simple calculators ignore.
Should I wait for panel prices to fall further?+
Waiting costs the savings you'd have earned meanwhile. If payback is under 6 years, each year of waiting forfeits roughly 15–20% of system cost in unrealized savings — almost always more than any further price decline. The math favors installing once the roof and paperwork are ready.
