How to Verify and Choose the Right Solar Vendor in India

Choosing the right solar vendor can make or break your solar investment. From fake promises to hidden costs, many first-time buyers fall into traps because they didn’t verify their installer properly. This guide from SolSetu walks you through simple yet essential steps to ensure you’re working with a reliable solar partner.

1. Check for MNRE Registration & Certifications

Always verify if the vendor is registered under the MNRE (Ministry of New and Renewable Energy) or with your state’s renewable agency. Certified vendors ensure compliance with subsidy norms and safety standards. Ask for proof of MNRE empanelment or relevant BIS certification.

2. Review Their Past Installations

Authentic vendors will proudly share details of their previous projects. Request photos, case studies, or customer testimonials. On SolSetu Vendor Profiles, you can view verified installation galleries and client reviews — a clear indicator of credibility.

3. Compare Quotations and Components

Don’t choose the cheapest quote blindly. A professional vendor provides transparent pricing with brand names of panels, inverters, and mounting structures. Compare technical specifications, warranties, and energy yield — not just the price tag.

4. Verify Warranty and After-Sales Service

Every solar system should come with two warranties: product and performance. Ensure your vendor provides local service support, quick replacement policies, and written warranty documentation for both panels and inverters.

5. Ask for Site Survey and Energy Audit

A trustworthy vendor will conduct a site survey before giving a final quote. This includes analyzing rooftop space, orientation, shadow analysis, and load patterns. Avoid vendors who quote instantly without visiting your site — it’s a red flag.

6. Look for Verified Online Presence

Check whether the vendor has an official website, verified business listing, and customer reviews on trusted platforms like SolSetu.com. Vendors verified by SolSetu undergo document and background checks to ensure reliability.

7. Sign a Transparent Agreement

Before payment, insist on a written agreement specifying the project scope, warranty terms, timeline, and payment schedule. Avoid cash-only transactions and demand proper GST invoices for your purchase.
