How to Choose the Right Solar Company in Kerala
Choosing the right solar company is a crucial decision as it can directly affect system performance, safety, and your long-term savings.
Since a solar installation is a long-term investment, you must evaluate companies carefully, rather than just selecting a provider based only on price. The points mentioned below will help you make a practical and better-informed choice.
- The first step you need to take forward is to check MNRE approval, as this confirms the company follows respective government standards and can support subsidy-related installations without compliance issues.
- Understand the type of solar systems offered by the solar company, because some homes are suitable for installing on-grid solar, which works best in areas that have a stable electricity supply.
- Inquire if the company can install a backup-based system, since off-grid solar is widely used in locations where power cuts are frequent or grid access remains limited.
- Check whether the solar company has flexible system options like hybrid solar systems that combine grid power and batteries, offering better reliability for your solar power usage.
- Review the company’s experience in Kerala, including their knowledge of monsoon conditions, local rooftop structures, and state electricity board procedures. This can be done by glancing through their recently completed solar projects.
- Confirm with the solar company if they can provide a warranty and timely service support, covering inverters, panels, installation workmanship, and resolving any kind of technical issues.
- Always look for transparency in pricing, ensuring costs for net metering, wiring, and approvals are clearly explained by their in-house team upfront.
By following all these points, as a homeowner, you can confidently choose the best solar company that delivers reliable installation, offers long-term support, and handles proper documentation for net-metering and subsidy approvals in Kerala.

Frequently Asked Questions (FAQ)
High-quality solar panels in Kerala last 25 to 30 years in Kerala’s climate. Most top-tier Solar Companies in Kerala brands offer a 25-year performance warranty guaranteeing at least 80% output at end-of-life. Kerala’s monsoon humidity is a factor, so panels with IP68-rated junction boxes and anti-corrosion aluminium frames are strongly recommended. Inverters typically need replacement after 10–15 years, adding a one-time mid-life cost to factor into your ROI calculation.
Yes. Net metering is mandatory and regulated for all grid-connected rooftop solar systems in Kerala under KSEB (Kerala State Electricity Board). Homeowners export excess solar energy to the grid and receive bill credits at the applicable KSEB rate. Applications are submitted through KSEB’s online portal. Your solar installer should handle all KSEB documentation — if a company cannot assist with this, it’s a red flag. The approval process typically takes 30–60 days from application submission.
Yes, Solar panels in Kerala generate electricity even during overcast monsoon days, using diffused sunlight. On a heavily cloudy day, panels typically produce 10–25% of their peak rated capacity. Annual production calculations for Kerala systems already account for this seasonal variation. For uninterrupted energy security during extended low-sunlight periods (like the June–August peak monsoon), a hybrid solar system with lithium battery backup is the recommended solution for Kerala homes.
In 2026, Kerala homeowners can avail of the Central Government’s PM Surya Ghar Yojana subsidy: ₹30,000 for systems up to 2 kW, ₹60,000 for 2–3 kW systems, and a maximum of ₹78,000 for systems above 3 kW. The state of Kerala does not provide an additional state-level subsidy. Applications are submitted via the national portal. Only ALMM-listed, Made-in-India panels qualify — confirm this with your installer before purchase.
No, routine solar maintenance in Kerala is affordable. Most MNRE-approved companies offer Annual Maintenance Contracts (AMC) ranging from ₹2,000 to ₹6,000 per year, depending on system size. AMC typically covers quarterly panel cleaning (especially important during Kerala’s post-monsoon dust season), bi-annual inverter health checks, cable and earthing inspections, and remote performance monitoring. A well-maintained system produces 10–20% more energy annually than a neglected one.
In 2026, Kerala homeowners can avail of the Central Government’s PM Surya Ghar Yojana subsidy: ₹30,000 for systems up to 2 kW, ₹60,000 for 2–3 kW systems, and a maximum of ₹78,000 for systems above 3 kW. The state of Kerala does not provide an additional state-level subsidy. Applications are submitted via the national portal. Only ALMM-listed, Made-in-India panels qualify. Confirm this with your installer before purchase.
Solar installation costs in Kerala in 2026 typically range from ₹45,000 to ₹65,000 per kWp for on-grid residential systems before subsidy. A standard 3 kW system (sufficient for a 4-member home with moderate usage) costs approximately ₹1.35–1.95 lakh before the PM Surya Ghar subsidy of ₹60,000–₹78,000. After subsidy, the effective cost drops to ₹0.57–1.17 lakh. Hybrid systems with lithium battery backup cost 40–70% more. Always compare at least 3 itemised quotes from MNRE-approved solar companies in kerala.
Conclusion
Switching to solar power in Kerala is a sound long-term investment, with rising KSEB tariffs, strong central subsidies, and improving solar technology, most Kerala homeowners achieve payback within 4–6 years and enjoy 20+ years of near-free electricity thereafter.
