Installation quality, net metering support and after-sales service — we ranked India's top solar energy companies based on homeowner reviews.
Residential solar adoption in India has grown 340% since 2021, driven by falling panel costs and rising electricity tariffs. But the market is fragmented and quality varies enormously. We analysed 8,000 homeowner reviews to help you choose an installer you can trust with a 25-year investment.
The post-installation gap
The most common complaint in solar reviews — appearing in 41% of negative feedback — is not installation quality but post-installation support: companies that are unresponsive once payment is complete, net metering applications that stall because the installer does not follow up with the DISCOM, and inverter issues that take weeks to address under warranty. Top-rated installers provide a named service contact and a documented escalation process before installation begins.
"The installation was perfect, but getting net metering approval took 4 months because they didn't follow up with the electricity board. Factor that timeline into your ROI calculation." — Verified WhoIsAtTop Review
Subsidy processing: where good installers earn their fee
PM Surya Ghar Muft Bijli Yojana provides subsidies of up to ₹78,000 for residential solar. Reviews show a clear bifurcation: installers who handle the entire subsidy application process end-to-end receive dramatically higher ratings than those who leave homeowners to navigate the portal alone. This single service differentiator now appears in nearly a third of all positive solar installation reviews.
Panel brand vs. installer quality
Homeowners frequently ask whether the panel brand (Waaree, Adani Solar, Tata Solar) or the installer matters more. Reviews suggest installer quality dominates: the same panel brand installed by a highly-rated company versus a poorly-rated one produces dramatically different long-term outcomes. Prioritise installer reputation over brand preference.
