How to Choose the Best Solar Company for Your Home
- Check MNRE empanelment: Only empanelled companies can process subsidy. Verify at mnre.gov.in.
- Read Google reviews: Look for 4+ stars with 50+ reviews. Ignore companies with no reviews.
- Get 3 quotes minimum: Prices vary by 15–25% for the same system — always compare.
- Check warranty terms: Minimum 5 years installation warranty, 10 years inverter, 25 years panel.
- Ask for previous project references: A good company will show you nearby installations.
- Verify GST registration: Unregistered companies = no GST invoice = no subsidy eligibility.
Red Flags — Companies to Avoid
- Promises "100% free solar" — misleading
- No physical office address
- Asks for 100% advance payment
- Cannot provide MNRE empanelment certificate
- No GST invoice offered
- Google rating below 3.5 or very few reviews
