Time-of-Day (ToD) tariffs charge more for electricity in peak hours and less during solar hours. India's 2023 rules set peak rates about 20% higher and solar-hour rates about 20% lower; a March 2026 draft amendment revises the peak multipliers, pushes rollout deadlines to 2027-28 and links ToD to demand response and mandatory storage for large solar prosumers. This explainer decodes both and their effect on rooftop-solar and battery economics.
India has roughly 70 GW of offshore wind potential off Gujarat and Tamil Nadu but zero megawatts installed. A ₹7,453 crore viability gap funding scheme approved in September 2024 aims to build a first 1 GW — 500 MW off each state — with SECI running the auction and the first tender expected off Tamil Nadu in 2026. This analysis explains the scheme, the economics and why India is a decade behind.
Residential rooftop solar in India pays back in roughly 3.5–6 years after the PM Surya Ghar subsidy (₹78,000 max), and commercial systems in 3–5 years with 40% accelerated depreciation — an effective 15–25% return over 25 years. Real 2026 payback by system size, state and financing.

Firm and Dispatchable Renewable Energy (FDRE) bundles solar, wind and batteries into one contract that supplies power on a fixed schedule. Since India's June 2023 guidelines, nodal agencies have auctioned roughly 14 GW of FDRE and round-the-clock capacity, with tariffs from ₹4.69 to ₹6.74/kWh and the first project commissioning in 2026.
India is moving to one market-clearing price across all power exchanges. CERC's July 2025 order proposes day-ahead coupling from January 2026, run round-robin by IEX, PXIL and HPX. A Grid-India pilot found just a 0.3% welfare gain, yet it reshapes renewable price discovery and IEX's dominance.
In 2026 the best solar panels in India come from Waaree, Adani, Tata Power Solar, Vikram Solar, Premier Energies or RenewSys — all ALMM List I approved for the PM Surya Ghar subsidy. Budget ₹25–₹40 per watt, and prefer TOPCon over mono PERC.
On-grid solar is the cheapest for most Indian homes (~₹50,000/kW, ₹78,000 PM Surya Ghar subsidy, no battery) but goes dark in a power cut. Off-grid runs without the grid but costs 2–3x more and gets no subsidy. Hybrid adds battery backup and keeps the solar subsidy. This guide shows how to choose.
India cut the ₹1.4 lakh crore legacy dues that once choked renewable developers to ₹4,109 crore by February 2026. But ₹25,287 crore of current dues, ₹6.47 lakh crore of accumulated DISCOM losses and a 40 GW PSA backlog keep off-taker risk — and the solar cost of capital — high.
A home solar battery in India in 2026 costs roughly ₹35,000–45,000 per usable kWh for lithium (LiFePO4) and ₹8,000–10,000 per kWh for tubular lead-acid — a 5 kWh lithium pack runs ₹1.8–2.5 lakh installed. PM Surya Ghar does not subsidise the battery itself.
Net metering in India lets rooftop solar owners export surplus power to the grid and offset future bills. Under the Electricity (Rights of Consumers) Rules, net metering is allowed up to 500 kW or sanctioned load, whichever is lower; larger systems use net billing or gross metering. A draft 2026 amendment proposes mandatory storage above 500 kW, while PM Surya Ghar has stripped out fees and separate agreements for small homes.
India's renewable build-out is outpacing its grid. Transmission caused ~two-thirds of the 470 GWh of clean power curtailed on the ISTS in Q1 2026, and line additions are running at ~80% of target. The Green Energy Corridor and a ₹2.44 lakh crore CEA plan must close the gap to hit 500 GW by 2030.
