Who Is It For?
Someone with an interest in electrical systems, project management and sales. You do not need to be an engineer — most installation work is done by certified electricians you hire. What you need is the ability to generate leads, manage projects and maintain customer relationships.
Target customers: Homeowners (₹50L+ property values), housing societies, schools, small factories and SMEs with high electricity bills.
What Works in This & Why?
Government subsidies (PM Surya Ghar scheme) cover up to 40% of installation costs for homes — this dramatically lowers the buyer's hesitation. Once installed, panels require annual maintenance contracts (AMC) which are pure recurring revenue at 60–70% margins.
Rising electricity prices mean the financial case for solar improves every year without any selling effort on your part.

Scope in India
States like Rajasthan, Gujarat, Maharashtra, UP and Karnataka receive the highest solar irradiance and have the most proactive state DISCOM policies. But even in lower-irradiance states, the economics work given subsidies and rising grid tariffs.
The government's target of 1 crore rooftop solar installations under PM Surya Ghar means there is a decade of demand baked into policy.
Things to Be Mindful Of
- MNRE and DISCOM empanelment is required for subsidy-eligible installations — a must-have.
- Project cash flows can be lumpy; ensure you collect advance payments before procurement.
- Quality of panels varies enormously — a bad installation will haunt you through complaints and repairs.
- Competition from large national players (Tata Power Solar, Adani) is increasing in metros — differentiate on local service and speed.
Current Landscape in India
India installed over 15 GW of rooftop solar in 2023, and growth is accelerating under the PM Surya Ghar scheme which aims to cover 1 crore homes. Tata Power Solar, Adani Solar and dozens of regional players are active — but Tier-2 cities and residential colonies remain largely underserved by quality installers.

Real Founder Story
Vikram Shetty
Surya Power Solutions · Ahmedabad · 2022
Month 6
₹8 lakh/month
Month 12
₹28 lakh/month
Team size: 11 (4 installers, 2 electricians, 2 sales, 1 operations, founder + 1 admin)
What Worked
Winning PM Surya Ghar subsidy paperwork on behalf of customers became the biggest differentiator. Competitors just did installation — Vikram's team handled the full subsidy filing, netting customers ₹30,000–78,000 back. This drove 60% of new business through referrals alone.
Biggest Mistake
Scaling installation teams before cash cleared. Solar projects often have 45–90 day payment cycles (especially DISCOM approvals). He hit a ₹18L cash flow crunch at month 8 and had to pause 3 projects. Now takes 30% advance, 40% on installation start, 30% on commissioning.
Pros & Cons
Pros
- Massive policy tailwind and government subsidies reduce buyer friction
- Recurring revenue from annual maintenance contracts (AMC)
- Strong referral dynamics in residential colonies
- Growing market with a very long runway
Cons
- Working capital intensive — buy panels before receiving full payment
- Regulatory empanelment with MNRE and DISCOM required
- Technical quality issues can permanently damage reputation
- Large national players entering smaller cities and compressing margins
Real-World Proof
— Crossed ₹300 crore revenue from residential solar within ~3 years; 20,000+ home installations across 16 cities; raised $40M Series B (Lightspeed, Dec 2024)
"We wanted to create the safest solar solutions for homes and introduced cyclone-proof installations with performance guarantees."
— Bootstrapped and profitable at ₹100 crore B2B before pivoting to residential; crossed ₹200 Cr then ₹300 Cr revenue; raised $4M seed (2022)
"Families weren't aware of the benefits of solar and there were a lot of myths that needed to be addressed."
— Cumulative grid-connected rooftop solar reached 11.8 GW in FY24, a 33.86% jump year-on-year (MNRE data via IBEF)
