OPEN REFERENCE DATA
The India Solar Databook
The reference numbers the Indian solar sector keeps re-deriving — solar resource by state, the standards that govern equipment, subsidy rates, technology benchmarks, and cost bands. 5 datasets, 63 rows, every table dated, sourced, and downloadable as CSV.
State-Wise Solar Resource & Expected YieldSolar resource and expected generation for every Indian state and union territory. Specific yield is computed from average peak sun hours at a 78% performance ratio — the realistic figure for a well-built Indian rooftop, not a datasheet maximum.36 rows · Updated July 2026Indian & IEC Standards for SolarThe standards that actually get cited in Indian solar specifications, tenders, and quality disputes — each explained in one plain sentence, with what it governs. Use it to read a technical specification, or to check what a vendor is claiming compliance with.12 rows · Updated July 2026Rooftop Solar Subsidy & Incentive RatesCentral financial assistance rates for rooftop solar in India, by consumer segment and capacity slab. Rates are national and fixed per kW — an inflated quotation does not increase the subsidy you receive.5 rows · Updated July 2026Module Technology BenchmarksTechnical benchmarks for each mainstream module technology available in India. Use these ranges to sanity-check a datasheet or a vendor claim — figures materially outside these bands warrant questions.5 rows · Updated July 2026Installed Cost Benchmarks by SegmentIndicative 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.5 rows · Updated July 2026
Using This Data
These datasets are published free for researchers, engineers, journalists, and students. You are welcome to cite, reproduce, and build on them — an attribution link to hariturjamission.com is appreciated. Where a figure is an indicative market range rather than a measured statistic, the dataset says so explicitly.
