A 4 kW solar system needs 300–350 sq. ft. and costs ₹2,90,000–₹3,10,000 before subsidy. With a ₹78,000 subsidy and ₹22,000 Freyr Energy discount, you save ₹1,00,000 upfront. It generates about 480 units per month, cuts electricity bills by up to 90%, and delivers a 3–4 year ROI.
Solar energy has been in the talks for decades, yet only a handful of businesses and households have shifted their dependency towards it. Despite offering clean, green, and efficient power, solar energy was often overlooked due to the hefty upfront installation costs. However, recent government initiatives and growing interest in adopting solar power have changed this scenario drastically.
The government’s subsidy for installing solar panels has gained positive attention and encouraged more people to go solar. These subsidies help reduce initial costs and make net metering more accessible. With all this in place, a 4kW solar panel system works exceptionally well in meeting household power requirements.
