Everything you need to know about subsidies, net-metering, high-efficiency modules, warranties, and commercial solar returns.

1 How much subsidy do I get under PM Surya Ghar Muft Bijli Yojana in Karnataka?

Under the national PM Surya Ghar Muft Bijli Yojana, residential rooftop systems receive direct DBT subsidies into their bank accounts:

1 kW System: ₹ 30,000 subsidy

Sneha Renewables manages the complete national portal registration, DISCOM inspection, and meter replacement.

2 What is the difference between Reliance HJT and standard Mono PERC panels?

Reliance RNE Pro-L Heterojunction (HJT) panels combine crystalline silicon with amorphous thin-film silicon:

Higher Temperature Coefficient (-0.24%/°C): Generates up to 10-15% more power on hot summer days in Karnataka vs Mono PERC.
85%–90% Bifaciality: Produces significant additional power from rear-reflected light.
30-Year Performance Retention (90.3%): Extremely low annual degradation (0.3%/yr) compared to 0.55%/yr on older technology.

3 How does Net Metering work with HESCOM, BESCOM, and GESCOM?

With a bidirectional Net Meter installed by your Karnataka DISCOM (HESCOM / BESCOM), power generated during daylight hours runs your premises first. Any excess electricity is exported back to the state power grid, rolling your meter backward. At the end of the billing cycle, you are only billed for the net units consumed.

4 What is the typical financial payback period for Commercial & Industrial Solar?

Commercial enterprises in Karnataka paying ₹7.50 to ₹9.00 per unit typically achieve complete CAPEX payback in 3.2 to 3.8 years. Combined with 40% Accelerated Depreciation tax benefits in Year 1, the internal rate of return (IRR) typically exceeds 28% per annum.

5 Are all solar panels ALMM and BIS approved by MNRE?

Yes! Every single module supplied by Sneha Renewables — including Reliance New Energy RNE Pro-L and Avaada Electro TOPCon series — is 100% listed on the Ministry of New & Renewable Energy (MNRE) Approved List of Models and Manufacturers (ALMM) and certified under Bureau of Indian Standards (BIS).
