500 kW solar power plant cost in Gujarat
A complete, independent cost, land, generation and return breakdown for a 500 kW ground-mount solar plant in Gujarat.
A 500 kW plant fits a mid-sized industrial unit on captive use, or a small investor entering ground-mount solar.
Works as captive solar or a small PM-KUSUM Component-A plant.

The economics of a 500 kW plant, in plain words
Over its 25-year life a 500 kW plant in Gujarat generates about 8.3 lakh units a year. Under a DREBP PPA at ₹2.76/unit that is roughly ₹0.23 crore of revenue a year; on open access nearer ₹0.33 crore. After ₹0.04 crore of annual O&M, net income runs ₹0.19–0.29 crore a year, so the ₹2.3 crore build pays back in about 7.9–12.1 years and then earns largely profit. Claiming 40% accelerated depreciation shields roughly ₹0.23 crore of tax in year one, and undiscounted 25-year PPA revenue is around ₹5.75 crore.

Key considerations for a plant this size
A 500 kW ground-mount plant needs roughly 1.5–2 acres near a viable substation and is usually funded with 25–30% equity and the rest as project debt. Most owners at this size go the DREBP route for a fixed 25-year PPA, or run captive to offset an industrial load. A bankable DPR and a clean land title are what decide financing.
