How to Choose the Best Solar Company in India

Before selecting a solar company, ask the following questions.

1. Does the Company Have Relevant Project Experience?

A company experienced in residential rooftop solar may not necessarily be the right choice for a multi-megawatt industrial project.

Check whether the company has completed projects similar to yours.

2. What Technology Does It Use?

Ask about:

• Solar module technology
• Inverter technology
• Battery chemistry
• Monitoring system
• Energy management system

For modern solar projects, N-type technologies such as TOPCon and HJT are increasingly important in the module market.

A product supplier and an EPC company provide different services.

An EPC provider may manage:

Engineering → Procurement → Construction → Commissioning

This can simplify project execution, especially for commercial and industrial customers.

4. What Warranty Is Provided?

Check both:

• Product warranty
• Performance warranty

The warranty should clearly mention the product, duration, terms and claim process.

5. What Happens After Installation?

Ask about:
