The solar industry in India has evolved from a niche market into one of the fastest-growing renewable sectors globally. With climate change awareness rising and the Indian government’s clear push towards clean energy, the demand for solar panel installation businesses in India is soaring in 2025.
Now more than ever, both urban households and rural enterprises are adopting solar systems to reduce energy costs and carbon footprint. That creates a massive opportunity for entrepreneurs to tap into this growth. And the best part? India’s policy framework now strongly supports renewable startups.
So, if you’re thinking about how to start a solar company in India, you’re already on the right path. This guide will walk you through every step, from planning to scaling your business.
Understanding the Indian Solar Market in 2025
India’s installed solar capacity is expected to reach 280 GW by 2030. The solar boom in 2025 is driven by rising electricity costs, falling solar prices, and favorable policies like PM Surya Ghar Yojana and PLI scheme.
The MNRE offers subsidies up to 40% for residential rooftop systems. Plus, net metering allows homeowners to sell excess power back to the grid. These incentives boost demand for solar installers.
Target markets include:
- Individual homes in urban areas
- Schools and hospitals
- SMEs and warehouses
- Agricultural pumps and rural businesses
Before you jump in, research your competitors—local EPC companies, online solar marketplaces, and franchise chains.
Choosing Your Solar Business Model
Picking the right business model can make or break your startup. There are four main models in India’s solar space:
- Residential Rooftop Solar: Good for volume, recurring income.
- Commercial Solar Projects: High-ticket but low frequency.
- EPC Contractor: Offers end-to-end design, procurement, and installation.
- Franchise Partner: Less risk but lower control.
Decide whether you want to serve homes, factories, or both. Also, determine if you’ll sell installations only or offer full solutions (design to maintenance).

Legal Formalities and Business Registration
To run legally, you must:
- Register your company (Proprietorship/LLP/Private Limited)
- Get a GST number for invoicing and taxes
- Register with MNRE as an authorized vendor (important for subsidy eligibility)
- Apply for state DISCOM empanelment
- Obtain local licenses and certifications (like electrical contractor license)
Following all legal steps boosts credibility and allows you to take government projects.
Investment & Funding Options
You’ll need ₹8–₹15 lakhs initially to cover:
- Tools and solar kits
- Transport
- Technician salaries
- Office setup
You can apply for startup loans via Mudra Yojana, or approach green investors. Also explore MNRE capital subsidies and state-specific schemes. Banks like SBI and PNB offer solar business loans with lower interest rates.
Building Your Team and Skill Requirements
Solar installation is skill-intensive. You need:
- Certified solar technicians
- Site surveyors
- Sales executives
- Admin support
Train your staff via NISE or other MNRE-approved institutions. Poor workmanship can hurt your brand, so never compromise on training.
Choosing Reliable Equipment and Suppliers
The quality of your installations depends on your components. Stick with Tier-1 brands like:
- Vikram Solar
- Tata Power Solar
- Waaree
- RenewSys
Also choose compatible inverters (Sungrow, Delta, Growatt) and ensure your mounting structures meet IS standards.
Form partnerships with manufacturers for better pricing and after-sales service.
Installation Process and Quality Control
Always begin with a detailed site survey. Then:
- Design the system using tools like PVsyst or Helioscope
- Use standard safety protocols
- Ensure grounding and lightning arresters are used
- Post-installation testing (voltage, current, inverter sync)
Document each step. This builds customer trust and avoids future issues.
Marketing Your Solar Business in India
Local visibility is key. Use:
- Google My Business listing
- SEO-optimized website with testimonials
- Facebook ads targeting your city
- Partner with realtors and builders
- Distribute leaflets at RWAs
Offer referral incentives. Word of mouth still works wonders in India.
After-Sales Service and Maintenance
Solar isn’t install-and-forget. Provide:
- AMC packages
- Prompt tech support via WhatsApp
- Remote monitoring for clients
- Educate users on cleaning panels, inverter faults, etc.
Happy customers = 5-star reviews = more leads.
Profit Margins and Growth Potential
Margins on residential installations range from 15–25%. ROI typically takes 12–18 months.
Once stable, expand to:
- Battery storage systems
- Solar water pumps
- EV charging setups
The solar field is ever-expanding—so grow with it!
Challenges in Starting a Solar Business
It’s not all sunshine. Challenges include:
- Delayed subsidies
- Inconsistent net metering rules across states
- Untrained labor
- High competition from legacy brands
But if you offer quality, educate customers, and build relationships, you’ll overcome these.
Tools and Software You Should Use
Use tech to work smart:
- Solar design: PVsyst, Aurora Solar
- CRM tools: Zoho, Hubspot
- Lead capture: Facebook Forms, Justdial
- Invoicing: Vyapar, QuickBooks India
Automation saves time and boosts professionalism.
