Tata Power Solar, Roofsol, and Mahindra Solarize Lead India's Rooftop Solar Market in 2024

India's rooftop solar market continues to surge, empowering homeowners, industries, and institutions to take control of their energy needs while supporting the nation's clean energy transition. According to Mercom India's Solar Market Leaderboard 2025, the year 2024 marked a major leap in the rooftop solar segment, with Tata Power Solar, Roofsol Energy, and Mahindra Solarize leading the pack among India's top solar companies.

India's Rooftop Solar Growth in 2024
India added an impressive 3.2 gigawatts (GW) of rooftop solar capacity in 2024 - an 86% increase from 1.7 GW in 2023. This rapid growth was fueled largely by the residential solar segment, supported by government programs such as the PM Surya Ghar: Muft Bijli Yojana, which provides subsidies and financing options to encourage homeowners to adopt solar panels.

However, the sector also faced some challenges, including delays linked to the Domestic Content Requirement (DCR) policy and issues within the DCR verification portal. Despite these hurdles, India's cumulative rooftop solar capacity reached 13.7 GW by the end of 2024, reaffirming its position as one of the fastest-growing solar markets in the world.

Top Solar Companies Driving the Rooftop Revolution
The top five companies - Tata Power Solar, Roofsol Energy, Mahindra Solarize, Gentari (formerly Amplus Solar), and Kalpa Power - together accounted for nearly 30% of India's rooftop solar installations in 2024. Let's take a closer look at how each company shaped the market:

1. Tata Power Solar: The Market Leader
Tata Power Solar retained its leadership position with a 19.4% market share in 2024. The company's continued focus on residential and commercial rooftop projects, alongside its nationwide installation network, has made it a trusted name in the solar industry.
With a 37.9% year-over-year growth, Tata Power Solar strengthened its presence through quality service, reliable solar panels, and customer-centric financing models. Their projects under the Surya Urja Rooftop Yojana have contributed significantly to solar adoption across major Indian cities.

2. Roofsol Energy: The Fast-Rising Contender
Roofsol Energy climbed to the second position with a 4% market share, achieving an impressive 82.3% increase in installed capacity compared to the previous year. The company's growth has been driven by its expertise in the industrial solar sector, serving clients in automotive, textiles, pharmaceuticals, and food processing industries.
Roofsol's focus on custom engineering solutions and high-efficiency solar panel systems has earned it a strong reputation for reliability and innovation in the commercial and industrial segment.

3. Mahindra Solarize: Strengthening C&I Leadership
Mahindra Solarize, part of the Mahindra Group, secured the third spot with a 2.4% market share. The company witnessed strong demand from commercial and industrial (C&I) clients, delivering reliable rooftop installations that help businesses reduce operational costs and meet sustainability goals.
In 2024, Mahindra Solarize expanded its portfolio of on-grid and hybrid solar systems, supporting customers with end-to-end project management, from design and engineering to post-installation maintenance. The company's commitment to quality and long-term value has made it one of India's most trusted solar partners.

4. Gentari (formerly Amplus Solar): Transitioning with Strategy
Gentari, previously known as Amplus Solar, dropped to the fourth position following a 51.4% decline in installations. However, the company remains a significant player in the market, focusing on renewable energy integration, EV charging, and clean energy transition strategies for businesses.
Gentari's rebranding and diversified portfolio reflect its broader vision to lead in sustainability and net-zero energy solutions across Asia.

5. Kalpa Power: A Strong New Entrant
Kalpa Power made its debut among the top five rooftop solar installers in India, achieving a 1.8% market share. The company's projects span the manufacturing, chemicals, infrastructure, and education sectors, reflecting its strong execution capability and customer-focused approach.

Government Incentives: Subsidies under the PM Surya Ghar scheme have made rooftop solar systems more affordable for homeowners.

Declining Costs: The cost of solar panels has dropped by over 80% in the past decade, making solar a smart long-term investment.
