India is stepping into a new era of clean energy, and the PM Surya Ghar: Muft Bijli Yojana is a shining example of that commitment. Launched to make solar power accessible and affordable, this scheme aims to empower 1 crore households by providing up to 300 units of free electricity every month through rooftop solar installations.

With a financial outlay of over ₹75,000 crores, the mission is clear, reduce energy costs, promote renewable energy adoption, and contribute to a greener planet.

Why a 3kW Solar Rooftop System is the Perfect Fit

For many households, especially in urban areas like Mumbai, a 3kW solar rooftop system is the sweet spot. It can drastically cut electricity bills, sometimes bringing them down to zero, while providing energy independence for years to come. On average, such a system can generate 12–15 units of electricity per day, enough to meet the energy needs of a medium-sized home.

Eligibility & Application Made Easy

To be part of the scheme, you must:

• Be an Indian citizen.
• Own a residential property with suitable rooftop space.
• Have an active electricity connection.
• Not have availed any prior government solar subsidy.

How to Apply:

1. Register at pmsuryaghar.gov.in.
2. Fill in your property details.
3. Get DISCOM approval.
4. Choose an empanelled vendor.
5. Complete installation with net metering.
6. After inspection & certification, the subsidy (up to ₹78,000 for a 3kW system) is credited directly to your bank account.

The Components of a 3kW Solar System

A standard setup includes:

• High Quality Solar Cables – UV- and weather-resistant solar cables with copper strands and XLPE insulation for lasting performance.
• ACDB & DCDB Boxes– Flame-retardant ACDB & DCDB boxes with premium breakers, SPDs, and fuses for safe power handling.
• Chamber Cover – Weatherproof, impact-resistant cover for protected wiring.
• Lightning Arrester – Zinc oxide arrester to divert voltage spikes.
• Earthing Kit – Galvanized rods and copper wires for durable grounding.

Savings & Sustainability Go Hand in Hand

With a 3kW system in Mumbai, you could save between ₹30,000–₹38,000 annually on electricity bills. Additionally, each installation offsets 3–4 tons of CO₂ emissions per year, helping fight climate change while improving air quality.

Government Support through Subsidy

The PM Surya Ghar Yojana offers:

• 1 kW system → ₹30,000 subsidy
• 2 kW system → ₹60,000 subsidy
• 3 kW system (or higher) → ₹78,000 subsidy (maximum)

Alternative Calculation Method

For the first 2 kW → ₹30,000 per kW

• So, 1 kW = ₹30,000
• 2 kW = ₹30,000 × 2 = ₹60,000

For capacity above 2 kW and up to 3 kW → ₹18,000 per additional kW

• Example: A 3 kW system = ₹60,000 (first 2 kW) + ₹18,000 (extra 1 kW) = ₹78,000

No extra subsidy beyond 3 kW, even if your system is larger.

In short: You get ₹30,000 per kW for the first 2 kW, then ₹18,000 per kW for the next 1 kW, with a maximum subsidy of ₹78,000.
