Kolkata, the City of Joy, is rapidly adopting solar energy as a reliable, cost-effective, and eco-friendly alternative to traditional power sources. With rising electricity bills, frequent load fluctuations, and increasing environmental awareness, both households and businesses across the city are shifting towards solar solutions. As a result, the demand for a trusted and experienced solar company in Kolkata has grown significantly.
But with so many companies in the market, how do you choose the right one? What should you look for? And how can a solar installation actually benefit you in the long run?
This guide covers everything.
Why Kolkata is Switching to Solar Energy
Kolkata receives a good amount of sunlight throughout the year, making it ideal for solar power generation. Here’s why solar adoption in the city is growing fast:
1. High Electricity Costs
Electricity bills in Kolkata have surged over the past few years. A rooftop solar panel system can reduce monthly bills by 70–90%, depending on usage.
2. Government Subsidies
Under the PM Surya Ghar Yojana and West Bengal Renewable Energy Development Agency (WBREDA), homeowners can receive significant subsidies for rooftop solar installations.
3. Eco-Friendly Choice
Switching to solar reduces carbon emissions and supports Kolkata’s mission to become greener and more sustainable.
4. Low Maintenance & Long Life
A good solar panel lasts 25–30 years, requires minimal maintenance, and offers maximum savings in the long term.
What Makes a Solar Company in Kolkata Truly Reliable?
Choosing the right solar partner is the most important step. A good company ensures proper system design, installation, maintenance, and after-sales support. Here’s what to look for:
1. Certifications & Expertise
Always choose a company that is:
- MNRE-approved
- Specialised in grid-tied, off-grid, and hybrid solar projects

2. Quality of Solar Panels & Inverters
Top solar companies use:
- Tier-1 solar panels
- Premium inverters (SMA, Growatt, Luminous, Microtek, etc.)
- Durable mounting structures
This ensures higher efficiency and long-term performance.
3. Customised Design & Site Survey
A reliable company won’t offer “one-size-fits-all” solutions. They will:
- Visit your site

No hidden charges. A genuine solar company in Kolkata will offer:
