The electricity bill is the obvious reason people go solar, but it's rarely the only benefit once a system is actually running.

• Lower, more predictable bills. Net metering offsets daytime consumption directly, and a correctly sized system can cut a monthly bill substantially.
• Subsidy support. Central and Tamil Nadu state subsidies of ₹30,000 to ₹1,00,000 are available for eligible domestic rooftop systems under current schemes.
• Protection from tariff hikes. Once installed, your generation cost is effectively fixed - you're insulated from future per-unit tariff increases on the portion you generate yourself.
• Long service life. Quality modules carry 25-year performance warranties, so the investment keeps paying back well past its break-even point.
• Lower carbon footprint. A typical 3 Kilo Watt peak residential system avoids several tonnes of CO₂ emissions a year compared with grid power.

The right system size depends on your roof area, shading and actual consumption pattern - Dev Solar's site survey covers all three before we quote.
