With rising electricity costs and frequent power consumption, installing a rooftop solar system has become a smart decision for homeowners. A 4kW solar system is ideal for medium to large households and helps significantly reduce electricity bills. Under the Government of India’s rooftop solar scheme, homeowners can also get up to ₹78,000 subsidy, making solar power more affordable and accessible.

What Is a 4kW Solar System?

A 4kW solar system is a rooftop solar setup that generates around 16 to 20 units of electricity per day, depending on sunlight conditions. It is suitable for homes that use multiple appliances such as air conditioners, refrigerators, washing machines, water pumps, televisions, and other electrical devices.

Benefits of Installing a 4kW Solar System

  • Reduces electricity bills by up to 90%

  • Produces clean and renewable energy

  • Requires very low maintenance

  • Solar panels come with up to 25 years of warranty

  • Government subsidy lowers initial investment

  • Increases the value of your property

Cost of a 4kW Solar System

The average installation cost of a 4kW solar system in India ranges between ₹2,40,000 to ₹2,80,000, depending on panel quality, inverter type, and installation structure. This cost generally includes solar panels, inverter, mounting structure, wiring, net metering, and installation services.

Government Subsidy up to ₹78,000

Under the PM Surya Ghar Rooftop Solar Scheme, residential consumers can receive subsidy benefits. The subsidy is capped at ₹78,000, even if the system capacity exceeds 3kW. This means a 4kW solar system is also eligible for the maximum subsidy of ₹78,000.

The subsidy amount is transferred directly to the consumer’s bank account after installation and approval.

Step-by-Step Process to Install a 4kW Solar System

Step 1: Rooftop Evaluation

Ensure your rooftop has:

  • Around 400–450 sq. ft. of shadow-free space

  • Strong structure to support solar panels

  • Direct sunlight for most of the day

Step 2: Online Application

Register on the official government rooftop solar portal. Select your state and electricity distribution company (DISCOM), then submit your electricity consumer details.

Step 3: Choose an MNRE-Approved Vendor

Select a government-approved solar vendor. Approved vendors manage installation, net metering, inspection, and subsidy documentation.

Step 4: Installation of Solar System

The vendor installs:

  • High-efficiency solar panels

  • Solar inverter and protection devices

  • Complete wiring and safety equipment
    They also apply for the net meter installation.

Step 5: Inspection and Net Meter Approval

DISCOM officials inspect the installed system and approve the net meter connection.

Step 6: Subsidy Disbursement

Once inspection is completed and documents are verified, the ₹78,000 subsidy is credited directly to your bank account.

Savings with a 4kW Solar System

A 4kW solar system can reduce monthly electricity bills from ₹4,000–₹6,000 to just ₹300–₹600. The investment typically recovers within 4 to 5 years, while the system continues to generate free electricity for over 25 years.
