The Truth About 3kW Solar System Cost

Currently the standard 3kw solar system price in india with subsidy drops down significantly. A good quality standard On Grid system will cost you about ₹1,44,000 to ₹1,50,000 total market price.

But here is the best part. Under the new PM Surya Ghar Muft Bijli Yojana a 3kW system gets the maximum capped subsidy of ₹78,000. This means your net out of pocket cost is roughly ₹66,000 to ₹72,000.

Premium Brands and Tata Solar 3kW Price

If you opt for premium brands the tata solar 3kw price or Waaree systems will cost about 15 percent to 20 percent more than standard local assemblers. Expect the gross quote from a Tata authorized dealer to be around ₹1,70,000 to ₹1,80,000 before subsidy. They use highly efficient Mono PERC or Bifacial panels and offer excellent after sales service.

Expert Pro Tip

If you live in a city with rare power cuts stick to On Grid. If you want a 3kw solar system with battery price be prepared to add at least ₹50,000 to ₹60,000 for a decent Lithium ion or tall tubular battery bank. Also remember that Off Grid systems are not eligible for the government subsidy.

In India a well installed 3kW system generates around 12 to 15 units of electricity per day on average. This translates to roughly 360 to 450 units a month which is enough to run a standard 2 to 3 BHK home including one AC running during the day fridge TV and fans.

How much area required for 3kw solar panel installation?

If you are using modern high efficiency panels such as 540W or 550W Half cut Mono PERC you will only need about 5 to 6 panels to build a 3 kilowatt array. If you use older 330W panels you might need up to 9 panels.
