Delhi homeowners and businesses have more help than ever to go solar. The central PM Surya Ghar: Muft Bijli Yojana offers a direct cash subsidy for home systems, while Delhi’s Solar Energy Policy adds its own capital rebate, generation-based incentive (GBI) and waived net-metering fees. Stack these with accelerated-depreciation tax breaks for companies and the case for rooftop solar in FY 2025–26 is hard to beat.
Solar panels are lighting up the world as a go-to choice for homes and businesses. But what makes them so special? This 2025 update shows exactly how panels conserve trees, cut carbon and boost your wallet.
Are high electricity bills pushing you toward renewable energy?
Solar power lets homeowners lock in decades of clean, low-cost energy—and 2025 incentives make the switch easier than ever. This guide walks you through panel types (including the newest TOPCon and HJT n-type technologies), roof checks, system sizing and financing so you can pick the best solar for home with confidence.
Delhi now lets multiple consumers share a single solar plant via Group Net Metering (GNM) or Virtual Net Metering (VNM). These frameworks overcome rooftop limits, slash bills and make solar one of the best investments for homes, societies and businesses.

Imagine a world where every appliance, factory and vehicle runs on an abundant, affordable and renewable fuel. Solar power is making that reality—today. This 2025 update explains how solar works, why its efficiency keeps rising and what it means for our wallets, our climate and the global economy.
Going solar isn’t just about being green—it’s an investment that pays steady, tax-free returns. This article shows the solar ROI Delhi homeowners can expect in 2025, using a real customer case study and updated price data.
India keeps promoting rooftop solar through a mix of central and state incentives. This guide lists every major 2025 rooftop solar subsidy for homes and businesses, with official sources so you can claim the right benefit.
| System size | Subsidy rate | Maximum payout |
|---|---|---|
| Up to 2 kW | ₹30,000 per kW | – |
| Third kW | ₹18,000 | – |
| 3 kW and above | Subsidy capped | ₹78 000 |
Subsidy is credited to the homeowner’s bank account after installation approval via the national MNRE portal.
Central CFA works with net-metering in most states, letting you earn bill credits for extra solar units.
| State | Capital subsidy | Generation-based incentive | Source |
|---|---|---|---|
| Delhi | ₹10,000 / kW (max ₹30,000) | ₹3 / kWh for ≤3 kW, ₹2 / kWh for 3–10 kW | Delhi Solar Portal |
| Maharashtra | none (CFA only) | none | MSEDCL i-SMART |
| Tamil Nadu | ₹20,000 / kW | optional GBI in select phases | TEDA |
| Assam | about 40 % of cost | – | AEDA |
| Goa | 40 – 50 % of cost | – | GEDA |
| Gujarat | ₹10,000–₹20,000 / kW* | – | GEDA |
| Uttar Pradesh | ₹15,000 / kW (max ₹30 000) | – | UPNEDA |
*Awaiting new 2025 policy. Check GEDA circulars for updates.

Businesses do not get CFA. Instead they save through tax and policy levers:
| Incentive | Details | Benefit |
|---|---|---|
| Accelerated depreciation | 40 % in year 1 under Income-Tax Section 32 | Cuts taxable income, shortens pay-back |
| Net / gross metering | Allowed in most states, export credits carry 12 months | Reduces power bills, adds revenue |
| GST input credit | Solar supply attracts blended 13.8% GST | ITC recoverable for businesses |
State policies can add GBIs, banking, or wheeling charge waivers. Example: Delhi pays ₹1 / kWh GBI for early C&I adopters up to 200 MW.
For state top-ups, apply on the respective DISCOM or energy-department portal.
Can I get both central and state subsidies?
Yes. Central CFA plus any state capital subsidy or GBI, subject to that state’s rules.
Does subsidy apply to batteries?
No. CFA covers solar panels, inverter, mounting, and wiring only.
Do I pay tax on the subsidy?
Current Income-Tax rules treat residential CFA as a price discount, not taxable income.

Thinking of harnessing India’s abundant sunshine? This guide explains the rooftop solar installation process from booking and site survey to net-metering approvals. Updated with 2025 subsidy figures and typical costs, it also covers solar site-survey checklists and mounting-structure types so you can make informed decisions.
Delhi NCR’s scorching summers, winter haze and heavy dust mean solar performance can vary a lot by season. Delhi sees average highs near 38–40 °C in summer (even above 45 °C in heatwaves), and frequent fog or smog in winter. Studies show Delhi’s pollution cuts panel output ~12–17% in haze. NASA-based data (Delhi: lat 28.7° N) finds typical rooftop PV yields ~5.7 kWh/kW-day in summer, ~3.7 in winter, with an ideal fixed tilt around 26°. Dust storms and monsoon rains also block sun. These local factors make equipment choice critical: high heat or dirt can throttle cheap systems, so ignore brand hype and focus on the actual numbers.
For people with families living in independent houses or top-floor residences in Delhi, electricity bills often account for a major part of monthly household expenses. In 2025, understanding how your electricity bill is structured and how to reduce it is crucial if you're managing a home.
Let’s break down the key components of your electricity bill and explore smart ways to reduce it, especially through solar energy and subsidy optimization.
