Installed Cost Benchmarks by Segment
Indicative turnkey installed costs per kW across market segments, before subsidy. Published so buyers can tell a competitive quote from an outlier in either direction — quotes far below these bands usually indicate specification cuts rather than efficiency.

| Residential 1–3 kW | ₹55,000–75,000 | Yes | 3–5 yr | Smallest systems carry the highest per-kW cost. Subsidy materially reduces net outlay. |
| Residential 3–10 kW | ₹50,000–65,000 | Yes | 3–5 yr | Subsidy capped at ₹78,000 regardless of size above 3 kW. |
| Housing society 10–100 kW | ₹42,000–55,000 | Yes | 3.5–5 yr | Common-area CFA of ₹18,000/kW may apply up to 500 kW. |
| Commercial 100 kW–1 MW | ₹38,000–48,000 | n/a | 3–4.5 yr | No capital subsidy; accelerated depreciation improves post-tax returns. |
| Ground mount above 1 MW | ₹32,000–42,000 | n/a | 4–6 yr | Land, evacuation, and civil works shift the economics versus rooftop. |

How to Read This Data
- These are indicative market ranges, not surveyed statistics — treat them as a sanity band, not a benchmark price.
- Costs vary with module technology, structure specification, roof complexity, site access, and order size.
- A quote 30–40% below the applicable band usually reflects thinner structure steel, undersized cable, or missing protection equipment. Compare bills of materials line by line.
- Payback ranges assume prevailing commercial and residential tariffs and are before financing costs.
