Solar System Sizes and Prices — 1 kW to 100 kW

Work from your annual consumption, which is printed on your electricity bill, not from your roof area. In Jaipur each installed kilowatt generates roughly 1,600 units a year, so divide your annual consumption by 1,600 to get the capacity that would fully offset it. A home using 5,000 units a year needs about 3 kW; one using 8,000 needs about 5 kW. Your sanctioned load and available shade-free roof then confirm whether that capacity is achievable.

Indicatively ₹55,000 to ₹85,000 per kW for small residential systems, falling to roughly ₹40,000 to ₹53,000 per kW at 50 kW and above. Larger systems cost less per kilowatt because design, mobilisation and DISCOM process costs spread across more capacity. These are planning bands — a firm price follows a site survey.

For a home, 3 kW is usually the best value point because the PM Surya Ghar subsidy reaches its ₹78,000 ceiling there — beyond it, capacity is bought at full price. For a business, the best return comes from whichever size most closely matches your daytime consumption, because a self-consumed unit avoids the full retail tariff while an exported unit is credited at less.

No. Capacity beyond your consumption exports surplus at a lower credited value than the retail tariff you avoid by self-consuming, so returns fall as the system outgrows the load. Permitted capacity is also tied to your sanctioned load, so an oversized application can simply be refused. The right system matches your consumption — which is why we size from twelve months of bills.

Yes. The bands quoted across these pages are installed costs covering modules, inverter, mounting structure, cabling, protection, earthing, installation, testing and commissioning, plus the net-metering application and the PM Surya Ghar subsidy filing where applicable. What they cannot include is anything a survey has not yet revealed — structural reinforcement, a load enhancement or an unusually long cable run.

Any capacity in between. The pages list the sizes people most commonly search for, but panels come in roughly half-kilowatt steps, so a 4kW, 6kW, 7kW, 8kW or 12kW system is perfectly normal — we size to your consumption and roof, not to a menu. For a quick estimate on an in-between size, read the two nearest pages and interpolate — the same logic covers a 40 kW or 60 kW commercial plant between the 25, 50 and 100 kW pages; the per-kW price falls gently as capacity rises, so the midpoint is a safe planning figure until a survey firms it up.

Roughly speaking: modules are the largest share, then the inverter, then the mounting structure, cabling, protection and earthing — with installation labour, transport, net-metering liaison and documentation making up the balance. This is why two quotes for the same capacity can differ honestly: a heavier structure for wind loading, DCR modules for subsidy eligibility, or a better inverter each move the per-kW figure for reasons that show up over the next 25 years, not in the first week.
