100 kW solar power plant cost in Gujarat
A complete, independent cost, land, generation and return breakdown for a 100 kW ground-mount solar plant in Gujarat.
A 100 kW system suits a factory rooftop, a school, a hospital or a small commercial building looking to cut its electricity bill rather than sell power.
Best as a rooftop captive system under net metering / the Gujarat Solar Policy.

The economics of a 100 kW plant, in plain words
Over its 25-year life a 100 kW plant in Gujarat generates about 1.7 lakh units a year. Under a DREBP PPA at ₹2.76/unit that is roughly ₹0.05 crore of revenue a year; on open access nearer ₹0.07 crore. After ₹0.01 crore of annual O&M, net income runs ₹0.04–0.06 crore a year, so the ₹0.46 crore build pays back in about 7.7–11.5 years and then earns largely profit. Claiming 40% accelerated depreciation shields roughly ₹0.05 crore of tax in year one, and undiscounted 25-year PPA revenue is around ₹1.25 crore.

Key considerations for a rooftop system this size
At 100 kW the goal is self-consumption, not selling power. It sits on your own roof, needs no land, and offsets the most expensive slab of your electricity bill. Sizing follows your sanctioned load and daytime usage, and the connection runs through DISCOM net metering.
