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.” Homeowners and businesses can also compare a best solar panel company in Tamil Nadu when choosing an experienced installation partner.
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.
How to Choose a Solar Company in Coimbatore
Pick an installer that is MNRE-empanelled on the PM Surya Ghar portal, has a local office and service team in Coimbatore, handles TANGEDCO net metering paperwork for you, and gives a written warranty and service commitment. Those four checks decide whether you get your subsidy on time and whether anyone answers the phone in year five.

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. For textile businesses specifically, solar for textile mills in Tamil Nadu can help address the high electricity consumption associated with industrial operations.
Top Rooftop Solar Companies in Coimbatore (Expert-Curated)
Below are 7 established and reliable rooftop solar installers in Coimbatore, selected based on execution history, approvals, service capability, and after-installation support not just marketing presence.

Kondaas has executed hundreds of rooftop installations in Coimbatore, including large textile mills and commercial factories, making us one of the most experienced players in the region.
2. MAS Solar
Known locally for residential and small commercial installations. Best suited for standard home rooftops, though large industrial execution capacity is limited.
3. EcoSoch Solar
Focuses on sustainability-driven projects and CSR-aligned commercial buildings. Works well for institutions and eco-conscious clients.
4. Sunlit Solar
A regional EPC player handling residential and SME-scale rooftop projects, particularly in newer residential zones.
5. Waaree Solar (Local Channel Partners)
Waaree panels are widely used, but execution quality depends heavily on the local partner. Customers should verify who handles engineering and service.
6. Goldi Solar (Authorized Affiliates)
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:
- MNRE empanelment
- TANGEDCO net-metering experience
- Long-term service commitment
If any installer avoids these questions, consider it a red flag.
How Long Does Rooftop Solar Take in Coimbatore?
| Stage | Typical time |
|---|---|
| Site survey and quote | 1–2 days |
| TANGEDCO feasibility approval | About 15 days (official) |
| Installation on your roof | 1–3 days for a typical home system |
| Inspection, net meter, commissioning | 10–20 days |
| Total, application to switch-on | Officially 15–30 days; 30–50 days is common in practice |
The panels go up in 1–3 days. Most of the waiting is TANGEDCO paperwork, so the installer’s experience with approvals matters more than how fast they install.
Common Mistakes Coimbatore Customers Make
- Choosing the cheapest quote and losing 10–15% efficiency due to poor design. Comparing prices for similar system sizes can also help set realistic expectations, such as the 5kW solar system price in Chennai after subsidy.
- 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. For industrial buyers, it is equally important to assess the long-term financial returns, including the industrial rooftop solar ROI in Tamil Nadu, before selecting a system and installer.
Rooftop Solar Cost in Coimbatore: How Much Subsidy You Get (2026)
Two subsidies can apply to a home in Coimbatore. The central PM Surya Ghar subsidy is a fixed amount per kW, not a percentage. Tamil Nadu’s new state top-up (G.O. (Ms) No. 102, dated 19.09.2026) adds to it.
| System size | Central subsidy (PM Surya Ghar) | Tamil Nadu top-up (G.O. 102) | Your cost after both |
|---|---|---|---|
| 1 kW | ₹30,000 | ₹5,000 | our cost = installer’s quote − central subsidy − Tamil Nadu top-up. |
| 2 kW | ₹60,000 | ₹10,000 | our cost = installer’s quote − central subsidy − Tamil Nadu top-up. |
| 3 kW | ₹78,000 | ₹22,000 | our cost = installer’s quote − central subsidy − Tamil Nadu top-up. |
| 5 kW | ₹78,000 (capped) | ₹22,000 | our cost = installer’s quote − central subsidy − Tamil Nadu top-up. |
A 3 kW home system in Coimbatore can get up to ₹1,00,000 in combined subsidy (₹78,000 central + ₹22,000 state). Systems above 3 kW don’t get more, because both subsidies stop rising at 3 kW.
Conditions for the Tamil Nadu top-up: your PM Surya Ghar portal registration must be dated on or after 5 August 2026. The money is paid to your bank account by Direct Benefit Transfer through TEDA. The total budget is ₹50 crore on a first-come basis, so the top-up can run out.
Before finalizing your installation budget, it is also useful to understand the solar cost in Tamil Nadu after subsidy, as the final investment depends on system size and applicable incentives. At Kondaas, we maintain a ~90% first-pass approval success rate, saving customers months of back-and-forth.
