Frequently Asked Questions — 3kW Solar in Kerala

What is the exact price of a 3kW solar system in Kerala in 2026?

A complete 3kW on-grid solar plant costs between ₹1,95,000 and ₹2,05,000 before subsidy. With the ₹78,000 central subsidy under PM Surya Ghar Muft Bijli Yojana, your net investment is just ₹1,17,000 to ₹1,27,000 including all approvals, net-metering, and 5-year AMC.

How much electricity does a 3kW solar plant produce every month in Kerala?

A 3kW system produces an average of 12 to 15 kWh (units) daily, which equals 360 to 450 units per month. For a home that currently receives bi-monthly KSEB bills between ₹4,000 and ₹9,000, it brings electricity bills down to near ₹0.

How do I claim the ₹78,000 PM Surya Ghar subsidy?

Solis Green registers your application on the National Portal for Rooftop Solar (pmsuryaghar.gov.in) and coordinates KSEB technical feasibility approval. After installation and bi-directional meter testing, the ₹78,000 subsidy is deposited directly into your bank account within 30 days.

Can a 3kW solar system run my air conditioner and refrigerator?

Yes. A 3kW system generates ample power to easily run 1 or 2 energy-efficient inverter air conditioners along with a double-door refrigerator, water motor, washing machine, LED lights, and television.

What are the KSEB application and net meter fees?

The standard KSEB solar registration and feasibility fee is ₹1,180 (including 18% GST). Net meter testing fees range between ₹500 and ₹1,000 depending on the electrical section. Solis Green handles all paperwork and meter testing logistics.

What is the payback period for a 3kW solar system?

With monthly savings averaging ₹3,500 to ₹4,500, the payback period is 2.5 to 3.5 years. Since solar panels carry a 25-to-30-year performance warranty, you enjoy over two decades of free electricity after recouping your investment.
