Energy & Sustainability FAQs
How much does a solar panel system cost in India?
Solar system costs ₹1,00,000-₹15,00,000 for residential use (1-10 kW). With government subsidies and tax credits, net cost can be 40-50% lower. Average payback period is 5-7 years, after which electricity is free for 20+ years.
Is an electric vehicle worth buying in India?
EVs have lower running costs (electricity costs 1/4 of petrol) but higher upfront cost. If you drive 10,000+ km/year, an EV breaks even in 5-7 years. Plus, no road tax and lower maintenance costs.
What is carbon footprint and how to reduce it?
Carbon footprint is the total greenhouse gases your activities produce (measured in CO2 equivalent). Reduce it by using renewable energy, EVs, public transport, reducing air travel, eating less meat, and being energy-efficient at home.
How much electricity can solar panels generate?
A 1 kW solar system generates ~4-5 kWh per day in India (varies by location and season). A typical 5 kW system generates 20-25 kWh per day, enough for an average household's daily needs in most seasons.
What government incentives exist for solar panels in India?
India offers various subsidies (up to 40% for residential), tax benefits under Section 80A, accelerated depreciation for businesses, and net metering (sell excess to grid). Check your state's specific schemes for maximum benefits.
