Kerala’s increasing focus on sustainable energy has made solar power an attractive option for homeowners and businesses alike. With year-round sunlight and rising electricity costs, investing in a solar system is a smart move. However, the real challenge lies not just in choosing the right solar technology—but also in selecting the right installer.
The success of your solar installation largely depends on the quality, experience, and service standards of the installer you choose. This blog will walk you through what to look for when comparing solar system installers in Kerala, and how to avoid common pitfalls during the selection process.
Why Choosing the Right Installer Matters
Installing a solar system is not just about fixing panels on a roof. It involves technical knowledge, safety protocols, accurate system sizing, electrical work, grid permissions, and after-sales support.
A poor installation can lead to:
- Reduced system efficiency
- Roof damage or water leakage
- Safety risks like electrical faults
- Lack of support during system breakdowns
- Problems with net metering or approvals
Hence, comparing installers carefully is crucial for long-term value and performance.

1. Experience and Track Record
When evaluating solar installers, experience is key. Companies that have been in the industry longer are more likely to have refined their processes and handled a variety of installation scenarios.
What to Check:
- Number of years in business
- Total installations completed
- Familiarity with Kerala’s climate and rooftops
- Projects completed in residential vs commercial sectors
Installers with a proven track record are often more reliable and better equipped to handle technical challenges.
2. Licensing and Certification
In Kerala, proper licensing is essential to carry out grid-connected solar installations. Certified professionals ensure installations are up to code and meet all safety standards.
Key Points:
- Ensure the installer is authorized to apply for net metering with KSEB.
- Ask if their staff includes certified electricians or engineers.
- Check if they follow MNRE (Ministry of New and Renewable Energy) guidelines.
A licensed installer can also help you access government subsidies and approvals without delays.
3. System Design and Customization
No two homes or buildings are the same. A good solar installer should design a custom system based on your roof size, orientation, energy usage, and budget.
Signs of a Good Design Approach:
- Offers a site visit and inspection before quoting
- Uses solar path simulation tools to assess shading
- Considers your monthly power consumption and future needs
- Suggests optimal panel placement and inverter type
Avoid installers who offer a “one-size-fits-all” approach without evaluating your specific needs.
4. Quality of Components Used
Even if you’re not brand-conscious, the quality of solar components—like panels, inverters, mounting structures, and wiring—matters significantly.
Ask About:
- Panel type (monocrystalline vs polycrystalline)
- Inverter technology (string vs microinverter)
- Warranties on components (typically 10–25 years)
- Structural integrity of the mounting system
Make sure the installer sources Tier-1 quality components and clearly explains what’s being used and why.
5. Understanding Pricing and Transparency
When comparing quotes, don’t just look at the bottom line. The cheapest option isn’t always the best—and may result in compromises on service, safety, or component quality.
What to Look For:
- Detailed breakdown of costs (equipment, labor, permits, etc.)
- Transparent terms for warranties and servicing
- Clarity on what’s included (like net metering application, monitoring systems, etc.)
Be cautious of vague quotes or hidden costs that surface after installation begins.
6. Warranty and After-Sales Support
A solar system is a long-term investment. Problems may not arise immediately, but you’ll want the assurance of solid after-sales support when they do.
Compare Installers On:
- System warranty (typically 5–10 years from the installer)
- Panel and inverter warranties (manufacturer-based)
- Response time for service requests
- Availability of local technicians for on-site support
Avoid companies that outsource support entirely or disappear after installation.
7. Installation Timelines and Project Management
Some installers overpromise and underdeliver. Delays in permits, equipment delivery, or installation can be frustrating.
Ask These Questions:
- What is the expected installation timeline?
- Who handles the documentation with KSEB or local authorities?
- Will a project manager be assigned?
- How is the system performance tracked post-installation?
Professional companies offer a clear plan and stick to it.
8. Knowledge of Local Rules and Grid Integration
Installing a grid-tied solar system in Kerala involves paperwork and approval from the Kerala State Electricity Board (KSEB).
Your Installer Should:
- Handle KSEB approvals and net metering setup
- Understand your local DISCOM’s policies
- Be familiar with safety and electrical standards in Kerala
- Help you apply for relevant subsidies, if available
An installer unfamiliar with local rules can delay your project or cause compliance issues.
9. Monitoring and Support Tools
Modern solar systems often come with apps or dashboards to monitor performance in real time.
Good Installers Will:
- Set up a performance monitoring system for you
- Train you to understand your system’s data
- Provide alerts or remote assistance in case of performance dips
This helps you stay in control and ensures your investment continues to perform optimally.

- Feedback on post-installation support
- Any red flags about delays, unresponsiveness, or equipment issues
You can also ask neighbors or local community groups for recommendations.
