Quick answer: Home solar in Chennai typically means a 3kW to 10kW rooftop system. A 3kW system costs roughly ₹1.12–₹1.45 lakh after the PM Surya Ghar subsidy (up to ₹78,000), cuts your EB bill by up to 90%, and pays for itself in about 5–6 years. Sri Saran Solar handles the design, installation, subsidy application and net-metering paperwork from start to finish.

Why Chennai homes are going solar
- Lower EB bills: Chennai households pay roughly ₹6.50–₹9 per unit depending on slab. A rooftop system replaces most of that with free daytime generation.
- Strong sunshine: Chennai gets reliable sun for most of the year, so output is predictable.
- Subsidy support: PM Surya Ghar Muft Bijli Yojana gives ₹30,000 per kW up to 2kW, capped at ₹78,000 for 3kW and above.
- Protection from tariff hikes: Your cost of power is fixed from day one.
- Long life: Tier-1 panels carry a 25-year performance guarantee.
