Documents Required
Aadhaar, electricity bill (consumer no.), bank passbook, property proof, cancelled cheque. Apply through your DISCOM's online portal.
Processing Timeline
Net meter installation: 30–90 days after DISCOM approval. Subsidy disbursed directly to bank account after commissioning inspection.
⚡ How Net Metering Works
Net metering is the billing mechanism that makes on-grid solar financially powerful. Your bi-directional meter records both import and export:
Excess generation credits carry forward monthly (or annually in some states), effectively making the grid a free battery for your solar system.
Daytime Generation
Panels generate electricity. Excess (beyond home usage) is exported to grid — your meter runs backward, earning credits.
Nighttime Consumption
Draw power from grid as usual. At month end: Net Bill = imports minus export credits.
Zero Bill Possible
If annual solar generation ≥ annual consumption, bill can be zero. Surplus credits may carry forward per state DISCOM policy.
State Policy Varies
Settlement periods: monthly, quarterly or annually. AP & Telangana offer annual settlement — better for maximizing summer solar credits.

☀️ Why Go Solar in India 2026?
Electricity prices are rising 4–6% annually. A rooftop solar system pays for itself in 3–5 years, then generates free electricity for 20+ more years.
Slash Electricity Bills
A 3kW system can eliminate 60–100% of your monthly electricity bill. After payback, savings compound as tariffs rise — your panels become your best investment.
Subsidy Up to ₹78,000
PM Surya Ghar Muft Bijli Yojana: ₹30k/kW for first 2kW + ₹18k/kW for 2–3kW, capped at ₹78,000. Many states offer additional subsidies on top.
10× Better Than FD
A 3kW solar system with 4-year payback gives ~25% annualised returns over 25 years as tariffs rise. Far superior to FD (6–7%) or MF (12%) on a risk-adjusted basis.
Green & Resale Value
A 3kW system avoids ~2.5 tonnes of CO₂/year — equal to planting 115 trees annually. Solar also increases urban property resale value by 3–5%.
💡 Pro Tips to Maximize Solar Savings
Right-Size Your System
Size to cover 70–100% of your bill. Over-sized systems have lower ROI where net-meter export rates are low. Use 100 sq.ft per kW as a thumb rule.
Choose Mono PERC / Bifacial
Mono PERC and bifacial panels deliver 20–22% efficiency vs 15% for poly. Over 25 years, this means 30–40% more energy from the same roof space.
Shift Loads to Daytime
Run washing machines, EV charging, geysers and ACs during peak solar hours (10am–3pm). Maximise self-consumption and reduce night-time grid dependence.
Apply for Subsidy First
Register on pm-suryaghar.gov.in before ordering panels. Choose a DISCOM-empanelled installer and DCR (Made-in-India) panels to qualify for ₹78,000 subsidy.
Annual O&M Contract
A cleaning + inspection contract (₹2,000–4,000/year) keeps panels at peak efficiency. Dusty panels lose 15–25% output in Indian conditions — clean monthly in summer.
Smart Monitoring App
Install a Wi-Fi inverter with a monitoring app. Track daily generation, spot underperformance early, and validate actual vs projected savings in real time.
Compare 3+ Installers
Solar installation costs vary 20–40% between vendors. Get at least 3 quotes. Insist on ALMM-listed panels, Tier-1 inverters, 25-year panel + 10-year inverter warranty.
Plan for Future EV
If you plan to buy an EV in 5 years, add 1–2 extra kW now. Charging your EV during peak solar hours saves ₹1,500–₹3,000/month vs petrol — dramatically boosting ROI.
📐 How to Calculate Solar Savings
The key formulas used in this calculator:
Example: 3kW On-Grid, Tamil Nadu (5.2 sun hrs, ₹6.5/unit):
Monthly Gen = 3 × 5.2 × 30 × 0.80 = 374 kWh · Monthly Savings = ₹2,431
Net Cost = ₹1,73,000 − ₹78,000 = ₹95,000 · Payback = ~3.3 years
