Top 10 Solar Power Companies in Kerala – 2026

Kerala is one of India's fastest-growing solar states. As of early 2025, the state's installed solar capacity crossed 1,723 MW, with rooftop systems accounting for 72% of that total. In 2024, Kerala ranked among the top 3 states in India for rooftop solar installations. With rising KSEB electricity bills, generous subsidies under the PM Surya Ghar Yojana (up to ₹78,000 for a 3 kW system), and the state's own KSEB Soura Scheme, more homeowners and businesses are going solar in 2026 than ever before.

But picking the right solar company in Kerala is where most people get stuck. This guide lists the top 10 solar power companies in Kerala for 2026 — based on installation experience, subsidy expertise, customer trust, and service quality.

Top 10 Solar Companies in Kerala – 2026

1. EL SOL Power Solutions Pvt Ltd 

Location: Kottayam & Changanacherry | Founded: 2017 | Website: elsol.co.in

When it comes to the best solar company in Kerala in 2026, EL SOL Power Solutions Pvt Ltd is the clear frontrunner. Founded in Kottayam in 2017, this company has built an unmatched track record in just under a decade.

Here's what makes EL SOL stand out:

• 5,000+ satisfied customers across all districts of Kerala
• Kerala's first solar vendor to complete 1,500+ projects under the MNRE DBT Subsidy Scheme

EL SOL is managed by qualified electrical engineers, supported by MS&J Associates — a 20-year-veteran A-grade electrical contractor. Their full-service model covers site survey, system design, KSEB net metering registration, subsidy paperwork, and long-term maintenance — all under one roof.

They are an MNRE-approved channel partner, ANERT empanelled agency, and KSEB-registered Soura developer. This means customers get maximum subsidy benefit with zero paperwork hassle. Residential customers typically recover their investment in as little as 3.5 years. Commercial clients unlock up to 40% accelerated depreciation in year one.

No other solar company in Kerala combines local reach, subsidy expertise, and verified installation volume at this scale. EL SOL is the clear #1 for solar in Kerala in 2026.

2. Tata Power Solar

Tata Power Solar has a serious Kerala presence. When ANERT ran the state's distributed rooftop programme, over 7,700 Kerala households chose Tata Power Solar — the single largest vendor order in that scheme. They are the top choice for large institutional and commercial projects, and for floating solar installations on Kerala's reservoirs.

3. Sunsenz Solar (Moopens Energy)

Type: Kerala-based EPC | Coverage: All 14 districts

Backed by the Moopens Group, Sunsenz has installed over 30 MWp of solar capacity across Kerala, with repeat orders alone accounting for more than 10 MWp.

Their network of 120+ authorised solar dealers across all 14 districts ensures fast local support. They specialise in monsoon-rated, waterproof mounting structures — critical in a state that receives over 3,000 mm of rainfall annually.

5. V-Guard Solar

Type: Kerala-origin brand | Founded: 1977

V-Guard is a household name in Kerala for electrical products. Their solar division leverages decades of distribution and service infrastructure.

Waaree is one of India's largest solar panel manufacturers with active commercial and industrial project execution in Kerala. If you're planning a large installation above 50 kW — factory, warehouse, or commercial building — Waaree brings manufacturing quality and supply chain scale that smaller companies can't match.

Renewsys brings a manufacturer-backed quality advantage. The same company that made your panels also backs the installation warranty — ideal for schools, hospitals, and government buildings where long-term accountability matters.

10. Roze Solar Solutions

Type: Kerala-based EPC

Roze Solar Solutions specialises in customised solar systems designed around each client's specific energy needs. They serve residential and commercial customers with an end-to-end model from energy audit to maintenance — a good fit for non-standard rooftops or complex energy requirements.

Kerala Solar Subsidy 2026 – What You Must Know

• PM Surya Ghar Yojana: Up to ₹78,000 subsidy for a 3 kW residential on-grid system via MNRE-empanelled installers.
• KSEB Soura Scheme: State-level subsidy — up to 40% for eligible homeowners through KSEB e-Kiran developers.
• Net Metering: Export surplus power to the KSEB grid and earn monthly bill credits.
• Business Tax Benefit: 40% accelerated depreciation on commercial solar installations in Year 1.

Subsidies are not permanent. Installing in 2026 still puts you in the window for maximum benefit — waiting may cost you.

EL SOL Power Solutions Pvt Ltd ticks every box — 5,000+ customers, 18+ branches, Kerala's first 1,500-project MNRE subsidy milestone, and CII certification make them the most complete solar company in Kerala in 2026.
