Electricity bills in Delhi don’t seem to slow down—they just keep increasing. For many households, this has become a major monthly expense. That’s exactly why more homeowners are now looking at solar energy as a practical and long-term solution.

If your home falls in the small to medium category, a 3kW solar system is often the perfect fit. It balances cost, savings, and energy generation quite well.

In this guide, we’ll walk you through everything you need to know—from the 3kW Solar System price in Delhi with subsidy to savings and whether it’s the right choice for your home.

3kW Solar System Price in Delhi

Let’s start with the most important question—cost.

The price of a 3kW solar system can vary depending on the type of system, panel quality, and installation setup.

Average Pricing:

• Without subsidy: ₹1,80,000 – ₹2,20,000

• With subsidy: ₹90,000 – ₹1,20,000

This typically includes:
Solar panels
Inverter
Mounting structure
Complete installation

With subsidies in place, the overall cost becomes much more affordable than most people expect.

Subsidy on 3kW Solar System in Delhi

The government is actively promoting solar adoption through schemes like PM Surya Ghar Muft Bijli Yojana.

Subsidy Breakdown:

• Central subsidy: Up to ₹78,000

• Additional capital subsidy: ₹30,000

That’s a total benefit of around ₹1,08,000, which significantly reduces your upfront investment.

Extra Income Through GBI (Generation-Based Incentive)

Delhi offers an additional benefit that many people don’t even know about—the Generation-Based Incentive (GBI).

Here’s how it works:

• Monthly generation: ~300 units

• Incentive: ₹3 per unit

• Monthly earning: ₹900

So, apart from saving on electricity bills, you actually earn money from your solar system.
