How to Choose the Right Solar Power Companies in Kerala
Kerala, blessed with abundant sunlight and a growing awareness of clean energy, is rapidly becoming a hotspot for solar power adoption. From individual homes to large-scale institutions, the shift towards solar is more than just a trend — it’s a long-term solution for rising energy costs and environmental concerns.
However, deciding to go solar is only half the battle. Choosing the right solar power company is equally important. A reliable company will ensure quality components, proper installation, government compliance, and long-term support. A poor choice, on the other hand, can lead to inefficiency, low returns, and high maintenance costs.
This blog will walk you through all the essential factors to consider before choosing the right solar power companies in Kerala — helping you make an informed, confident, and cost-effective decision.
1. Understand Your Energy Needs
Before contacting a company, assess your current and future energy requirements. Consider the following:
- Monthly electricity consumption (in kWh)
- Number of appliances and their usage patterns
- Future energy needs, like electric vehicles or home expansions
- Available rooftop or land space
Having a clear understanding of your energy profile will help companies design a system tailored to your needs and prevent oversizing or undersizing.
2. Choose the Right Type of Solar System
Kerala offers three common types of solar systems:
- On-Grid Systems: Connected to the Kerala State Electricity Board (KSEB) grid. You can export excess energy and benefit from net metering.
- Off-Grid Systems: Independent of the grid and require battery storage. Ideal for remote areas.
- Hybrid Systems: Combine on-grid and off-grid features, with battery backup for critical appliances.
Ensure the solar company specializes in the system that best fits your lifestyle and locality.
3. Look for Certification and Licensing
Legitimate solar power companies in Kerala should have:
- MNRE (Ministry of New and Renewable Energy) approval
- Agency registration with ANERT (Agency for Non-conventional Energy and Rural Technology)
- Electrical contractor licenses
- Certified solar engineers and trained technicians
These certifications ensure that the company adheres to government standards, which is crucial if you’re planning to apply for subsidies or net metering.
4. Review Company Experience and Track Record
Experience matters. Look for companies with a proven track record of:
- Successful installations across Kerala
- Technical knowledge of grid integration and battery systems
- Experience in residential, commercial, and industrial projects
Ask questions like:
- How many systems have you installed?
- What is your average project completion time?
- Do you have references or testimonials?
Companies with a longer presence in the market are more likely to offer stable support in the future.
5. Evaluate Product Quality and Technology
Not all solar panels or inverters are created equal. Choose companies that offer high-efficiency, durable, and certified components. Some key factors to consider include:
- Panel Efficiency: Look for panels with efficiency rates above 18%.
- Inverter Quality: Ensure compatibility with your power requirements and solar setup.
- Warranty: Ideally, solar panels should come with a 25-year performance warranty and inverters with at least 5–10 years.
Avoid companies that use unknown or low-quality brands with limited support.
6. Check for After-Sales Support
A solar installation is a long-term investment. You need a company that offers:
- Routine maintenance services
- System performance monitoring
- Quick support for inverter or battery issues
- Annual inspections and cleaning
Make sure after-sales services are clearly included in your contract, and ask about the cost of extended service plans if needed.
7. Compare Quotations Wisely
When collecting quotations from solar power companies in Kerala, compare:
- Total system cost (including installation, materials, labor, and taxes)
- Breakdown of equipment used (panel brand, inverter specs, etc.)
- Government subsidy calculation
- Estimated ROI and payback period
Remember, the cheapest quote isn’t always the best. Focus on value, reliability, and long-term performance over price alone.
8. Ensure Net Metering and Subsidy Assistance
Kerala’s government offers financial support through the MNRE subsidy scheme. This includes:
- Up to 40% subsidy for systems up to 3 kW
- 20% subsidy for systems between 3–10 kW
Ensure the solar power company:
- Helps you with the subsidy application
- Handles net metering approvals
- Provides proper documentation and system compliance
Proper guidance on government procedures saves you time, money, and hassle.
9. Check Customer Reviews and Ratings
Customer feedback provides real-world insights into:
- Company reliability
- Installation quality
- After-sales service
- System performance
Look for customer reviews on forums, social media, or local community groups. Ask the company for case studies or direct references from past clients in your region.
10. Visit an Existing Installation (If Possible)
Before making your final decision, try visiting an existing installation nearby. It gives you:
- A look at real-world performance
- Insight into installation quality
- A chance to speak to the system owner
Most reliable companies will gladly arrange a site visit to help you build confidence.
11. Understand the Payment and Financing Options
Many solar companies now offer flexible payment options:
- EMI-based finance plans
- Zero down payment schemes
- Lease-to-own programs
Ask the company to explain payment stages, warranties, and penalties clearly in writing.
12. Transparency in Documentation
A professional company should provide clear documentation for:
- System design and specifications
- Warranty certificates
- Operation manuals
- Post-installation reports
- Government subsidy forms
Never proceed with a company that hesitates to put things in writing.
Conclusion
Choosing the right solar power companies in Kerala is a decision that affects not just your wallet, but your long-term energy security and environmental impact. By taking time to evaluate your needs and understanding the important factors — such as system type, product quality, service reputation, and government compliance — you can avoid costly mistakes and enjoy the true benefits of solar energy.
The right company will act not just as a vendor, but as a long-term energy partner. They will offer clarity, quality, and support every step of the way — from design to installation to after-sales service. Take your time, ask questions, and always choose a solar partner who values transparency and performance.
