Know Solar
Everything you need to understand solar energy in India — from how panels work to government subsidies, ROI calculations, and maintenance.
Solar Fundamentals
Core concepts every solar buyer should understand before making a decision.
How Solar Works
Understand the science behind solar panels and how sunlight becomes usable electricity in your home or business.
- Photovoltaic cells convert sunlight to DC electricity
- Inverter converts DC to AC (usable power)
- Excess energy exported to the grid via net metering
- Battery storage captures surplus for night use
Subsidies & Schemes
India's PM Surya Ghar Muft Bijli Yojana offers up to ₹78,000 subsidy for residential rooftop solar installations.
- Up to 3 kW: ₹18,000/kW subsidy
- 3–10 kW: ₹9,000/kW for additional capacity
- Apply via pmsuryaghar.gov.in portal
- Benefits available to all residential consumers
Types of Solar Systems
Choose the right system based on your electricity usage, budget, and whether grid power is reliable in your area.
- On-grid: Connected to DISCOM grid, earns credits
- Off-grid: Fully independent with battery bank
- Hybrid: Best of both — battery backup + grid export
- Community solar: Shared rooftop for societies
Environmental Impact
A typical 5 kW rooftop solar system prevents over 6 tonnes of CO₂ emissions every year — equal to planting 300+ trees.
- Zero carbon emissions during generation
- 25–30 year panel lifespan with minimal waste
- Reduces strain on coal-fired power plants
- India's solar capacity crossed 80 GW in 2025
Installation Process
From site survey to commissioning — a typical residential installation takes 3–7 days after approvals are received.
- Site survey & shadow analysis
- DISCOM application & net-metering agreement
- Panel mounting & wiring (1–3 days)
- Commissioning & subsidy paperwork
ROI & Savings
Most solar systems pay back their cost in 4–6 years, then generate free electricity for another 20+ years.
- Average payback period: 4–6 years
- IRR typically 18–25% for residential systems
- Zero fuel cost — sunshine is free
- Property value increases by 3–5% post-installation
