Frequently Asked Questions

Solar ROI & Subsidy Insights

Everything you need to know about rooftop solar economics in India.

How is the PM Surya Ghar: Muft Bijli Yojana subsidy disbursed?

Under the national PM Surya Ghar scheme, residential rooftop solar installations receive direct subsidy into the customer's bank account: ₹30,000 for 1 kW, ₹60,000 for 2 kW, and a maximum of ₹78,000 for 3 kW and higher. PV Power Tech assists with end-to-end portal registration and DISCOM net-metering commissioning to ensure swift subsidy disbursement.

How does 40% Accelerated Depreciation (AD) benefit commercial and industrial clients?

Commercial enterprises, LLPs, and private limited companies can claim 40% tax depreciation on the solar capital asset value in the very first fiscal year. For a corporate entity in the 25% to 30% income tax bracket, this delivers an immediate cash tax savings of 10%–12% of the total project cost, drastically shortening the ROI payback period to under 2.8 years.

What is the difference between On-Grid and Hybrid Solar Systems?

An On-Grid system synchronizes directly with the state DISCOM grid, exporting surplus daytime solar power via bidirectional net-metering. A Hybrid system integrates an advanced LiFePO4 battery pack, allowing the facility to store daytime solar energy for night usage and seamless backup during grid power outages.

How long do solar panels last and what is the degradation rate?

PV Power Tech installs Tier-1 Monocrystalline PERC & TopCon Bifacial modules with a 25 to 30-year linear performance warranty. TopCon cells exhibit ultra-low annual degradation (< 0.4% per year), ensuring your installation still generates over 87% of its rated capacity even after 25 years of continuous operation.
