Are you tired of soaring KSEB bills?
If you’ve traveled across Kerala recently, you’ve likely seen blue and black panels gleaming on rooftops from Kasaragod to Trivandrum. With electricity tariffs rising in 2026 and the PM Surya Ghar subsidy offering up to ₹78,000 for a 3kW system, switching to solar is a financial necessity.
At Kondaas Automation, we believe the transition to clean energy should be transparent. Choosing a solar partner is a 25-year commitment. In this guide, we provide a step-by-step roadmap to choosing your installer and a dedicated directory to navigate solar solutions across every major city in Kerala.
5 Steps to Choose the Right Solar Company in Kerala
Don’t just sign with the first vendor you meet. Follow this expert-level checklist to ensure your investment is protected.
1. Verify ANERT & KSEB Empanelment
The most critical step is ensuring the company is an ANERT-accredited installer. Only empanelled vendors like Kondaas Automation can process your government subsidy and handle the KSEB Net Metering application. If they aren’t on the official list, you will miss out on the ₹78,000 grant.

2. Demand a Physical Site Survey
Never accept a quote based only on your bill. A real expert must visit your roof to check for:
- Shadow Analysis: Checking for coconut trees or neighboring buildings that block the sun.
- Roof Integrity: Assessing if your concrete slab or tiles can handle mounting frames.
- Tilt Angle: Calculating the optimal angle (latitude ±5°) for maximum generation.
3. Check for Tier-1 Components
Ensure your provider uses high-quality panels from established manufacturers like Tata Power or Waaree. These components are built to withstand Kerala’s heavy monsoons and come with 25-year performance warranties ensuring 80% output after two decades.
4. Compare “Value,” Not Just “Price”
The cheapest quote often involves non-galvanized structures that rust in Kerala’s humidity or low-grade DC cables that pose fire hazards.
- Galvanized Iron (GI): Essential for preventing rust.
- IP67 Rating: Ensures junction boxes are waterproof during heavy rains.
5. Evaluate Local After-Sales Support
Your solar journey begins after installation. Ensure your chosen company has a robust local service network to handle maintenance within 24 – 48 hours. Kondaas Automation prioritizes localized support to ensure your system never stays offline.
