Coimbatore has always been an industrial and entrepreneurial powerhouse from textile mills and spinning units to modern IT offices and residential communities. With rising electricity costs and Tamil Nadu’s strong push toward renewable energy, rooftop solar installations in Coimbatore have moved from “optional” to “essential.”
As someone who has personally overseen rooftop power solutions in Coimbatore for over three decades, I’ve seen this evolution first-hand.
I’m Sanjay Kondaas, Founder & Managing Director of Kondaas Automation, and since starting Kondaas in 1995, I’ve worked across UPS systems, power backup, and now large-scale on-grid rooftop solar systems for homes, businesses, and industries across South India.
This article answers a common question honestly and practically:
Which companies in Coimbatore offer reliable rooftop solar panel installations and how do you choose the right one?
Why Rooftop Solar Is Booming in Coimbatore
Coimbatore is uniquely suited for rooftop solar because of:
- High year-round solar irradiation
- Power-intensive industries (textiles, spinning mills, manufacturing)
- Frequent demand charges and peak-hour tariffs
- Strong residential adoption in areas like RS Puram, Peelamedu, Saravanampatti, Ganapathy, and Singanallur
In many of these locations, we’ve installed systems on independent homes, apartments, factories, and mills each with very different load profiles and challenges.

Goldi manufactures panels; installations are carried out by affiliates. Suitable for cost-sensitive projects if service agreements are clearly defined.
7. Other MNRE-Approved Local EPCs
Several smaller installers operate in Coimbatore. While some do good work, customers must carefully verify:

- Long-term service commitment
How to Evaluate a Rooftop Solar Company (Expert Checklist)
From decades in this industry, these are non-negotiable filters:
- MNRE / TANGEDCO approval experience
- In-house engineers (minimum 10+ for large projects)
- End-to-end net metering support
- 25-year post-installation service clarity
- Fast warranty resolution (<7 days)
- Financing or zero-upfront options
- Local execution history in Coimbatore
If any installer avoids these questions, consider it a red flag.
Common Mistakes Coimbatore Customers Make
- Choosing the cheapest quote and losing 10–15% efficiency due to poor design
- Ignoring maintenance, causing long-term output loss
- Hiring non-MNRE vendors and missing subsidies
- Underestimating TANGEDCO paperwork and timelines
Solar is a 25-year asset. Installation quality matters more than initial price.
Subsidies & Regulatory Reality in Tamil Nadu (2025–2026)
- PM Surya Ghar subsidy: ₹14,588 per kW (up to 3 kW)
- Net metering timeline: Typically 4–6 weeks
- Approvals: Fully online via TANGEDCO portal
At Kondaas, we maintain a ~90% first-pass approval success rate, saving customers months of back-and-forth.
Final Thoughts from 30+ Years in Power & Solar
Rooftop solar in Coimbatore is no longer about “going green” it’s about energy independence, predictable costs, and long-term returns.
The right installer doesn’t just mount panels they:
- design for your load profile
- navigate regulations
- stand by the system for decades
If you’re evaluating rooftop solar whether for a home, office, or industrial unit, choose experience over promises.
