Everything you need to know before commissioning a commercial solar plant in India.
What is the cost of commercial solar installation in India?
Commercial solar installations in India typically cost between ₹30–₹45 per watt depending on system size, location and equipment quality. A 100 kW system costs approximately ₹35–₹45 lakhs before incentives. Accelerated depreciation (40% in Year 1) can reduce your net cost by 10–15%.
How much electricity bill savings can a business expect?
Most commercial solar customers see 70–90% reduction in electricity bills within the first year. Exact savings depend on sanctioned load, consumption patterns, and local DISCOM tariff rates. Businesses with grid tariffs above ₹8/unit see fastest paybacks.
What government incentives are available for commercial solar in India?
Commercial and industrial installations benefit from: (1) Accelerated Depreciation of 40% in Year 1 under Section 32 of the Income Tax Act, (2) Priority sector lending from NABARD and SIDBI, (3) State-specific DISCOM incentives and wheeling charges waivers, (4) Net metering benefits allowing export of surplus power to the grid.
How long does a commercial solar plant installation take?
A typical 50–500 kW commercial installation takes 15–45 days from site survey to commissioning. This includes design (5–7 days), DISCOM approval (7–15 days), procurement (7–10 days), civil and electrical installation (7–15 days) and final inspection and grid connection.
What is the ROI and payback period on commercial solar?
Commercial solar in India typically delivers payback in 4–6 years with an IRR of 18–28%. After the payback period, the plant generates free electricity for 20+ years. Total 25-year savings are typically 5–8x the initial investment cost.
What happens when there is no sunlight — nights, cloudy days?
Grid-tied commercial solar systems switch seamlessly to DISCOM grid power at night and on cloudy days. With net metering, excess daytime generation is exported to the grid and credited against your nighttime consumption, ensuring continuous operations at all times.
Does my roof structure support the weight of solar panels?
Most industrial and commercial roof structures comfortably support solar panels, which add approximately 12–15 kg/m² of distributed load. Our engineers conduct a free structural assessment during the site survey. If reinforcement is needed, we design accordingly with minimal cost impact.
