Solar Panel Installation Cost in Kolkata & Howrah (2026 Guide)
With rising electricity bills and government subsidies making solar more affordable, many homeowners and businesses in Kolkata and Howrah are switching to solar power. Here's a practical breakdown of solar panel installation costs, system sizes, and what to expect from start to finish.
Why Consider Solar for Your Home or Business
- Reduces monthly electricity bills significantly over time
- Government subsidy available for residential rooftop solar
- Backup power option when combined with a solar battery/inverter
- Low maintenance once installed, with 20-25 year panel life
- Increases property value with a modern power setup
Types of Solar Systems
On-Grid (Grid-Tied) System
Connected directly to the state electricity grid — excess power generated is exported back to the grid, reducing your bill through net metering. No battery backup during power cuts.
Off-Grid System
Uses batteries to store solar power, providing full independence from the grid — ideal for areas with frequent power cuts, but higher upfront cost due to batteries.
Hybrid System
Combines grid connection with battery backup, giving you both bill savings and power cut protection.

Government Subsidy on Rooftop Solar
Central and state subsidy schemes are available for residential rooftop solar installations, which can significantly reduce your upfront cost. Subsidy amounts and eligibility change periodically, so we recommend confirming the latest applicable scheme at the time of installation.
How Much Can You Save on Electricity Bills?
Actual savings depend on your system size, roof sunlight exposure, and current consumption pattern. As a general guide, a correctly sized system can offset a large portion of a household's monthly electricity usage — our team calculates this precisely during your site survey based on your last few months' bills.

Frequently Asked Questions
How long does solar installation take?
For a standard residential rooftop system, installation typically takes a few days once the site survey and material are ready, excluding subsidy/net metering approval time.
Do I need a battery with a solar system?
Not necessarily. An on-grid system works without a battery and is more affordable, but won't provide backup during grid power cuts — a hybrid system is needed for that.
How much roof space do I need for a 3kW system?
A 3kW system typically requires around 300 sq ft of shadow-free roof area, though this can vary based on panel type and layout.
