Each model requires a different level of investment, technical expertise, equipment, staff, and supplier support . For example, installation services need trained technicians and electrical expertise, while distribution requires inventory and storage facilities.

Choose a model that matches your available capital and technical capabilities. You can also begin with a focused service and expand into additional solar offerings as your customer base grows.

India’s solar market offers several business models, but each requires different skills, investment, equipment, and operational capabilities:

1. Solar EPC (Engineering, Procurement, and Construction) Firm

A solar EPC firm manages the complete solar project, from system design and equipment procurement to installation and commissioning. You can serve residential, commercial, industrial, or institutional customers and earn revenue from project execution. EPC businesses typically operate with margins of around 10%–20%.

2. Solar Installation, Servicing & AMC Provider

A solar installation business focuses on installing rooftop and ground-mounted solar systems for customers. You can also provide system inspections, troubleshooting, repairs, cleaning, and Annual Maintenance Contracts (AMCs) to generate recurring service revenue. Installation services can typically generate margins of around 15%–25%.

3. Solar Dealership, Retail & Product Distribution

You can sell solar panels and related equipment through a dealership, retail outlet, or distribution network. Your product range can include solar modules, inverters, batteries, mounting structures, cables , and other accessories. This model suits businesses that want to focus on sales and distribution rather than installation, with typical margins of around 5%–15%.

4. Energy Storage Solutions (ESS) Integration

An ESS business supplies and integrates battery storage systems with solar installations . You can design storage solutions that store excess solar electricity and supply power when solar generation falls or during power interruptions. This model typically offers margins of around 10%–20%, depending on system size and project requirements.

5. Solar PV Manufacturing & Module Assembly

A solar manufacturing business produces or assembles solar photovoltaic (PV) modules for sale to distributors, EPC companies, installers, or other buyers. This model requires substantially higher investment because you need suitable production facilities, machinery, raw materials, skilled workers, quality controls, and supply-chain arrangements. Manufacturers operating at scale can typically target margins of around 10%–20%.

Starting a solar panel business involves choosing a suitable market, completing required registrations, and building reliable supply chains. Follow these steps to establish your solar panel business, meet requirements, and start attracting customers:

Step 1: Conduct Market Research and Define Your Target Audience

Start by understanding the solar demand in your target area. Study local competitors, their pricing, popular system sizes, and the services they offer.

Identify your primary customers:

• Residential property owners
• Commercial establishments
• Industrial units
• Agricultural customers

Then choose the segment that matches your investment, technical capability, and expected demand.

Step 2: Complete Legal Business Registration and Tax Compliance

Choose a suitable business structure before starting commercial operations. You can register the business as a Sole Proprietorship , Partnership, LLP , or Private Limited Company .

Complete the registrations that apply to your business, including:

• PAN and business-related registrations
• GST registration , where applicable
• Business bank account
• Accounting and tax compliance setup

The 56th GST Council reduced the GST rate on specified renewable energy devices and parts from 12% to 5% , effective 22 September 2025 . Check the applicable HSN Code before invoicing because the 5% rate applies only to specified goods covered by the relevant entry.

Maintain proper invoices, purchase records, sales records, and tax documents from the beginning.

For quick verification of a business’s GSTIN, you can use the GST Number Search tool to check GST registration details.

Step 3: Secure Electrical Contractor Licensing and Mandatory Certificates

If your business installs solar systems, obtain the Electrical Contractor License required by your state before undertaking electrical installation work. Check the applicable state electricity department rules because licensing requirements differ across states. You should also:

• Hire licensed electricians to handle electrical connections and related work.
• Employ trained solar technicians who can install modules, inverters, mounting structures, and wiring correctly.
• Obtain the certifications or product approvals applicable to the solar equipment you sell or install.
• Keep licenses, certificates, and technical documents ready when applying for vendor empanelment or project approvals.

Do not assume that one license covers every solar activity. Confirm the exact requirements for your state and the type of solar projects you plan to undertake.

Step 4: Get Empaneled with DISCOMs and MNRE Portals

If you want to undertake eligible rooftop solar projects under government-supported programs, check the applicable vendor empanelment requirements. The process may involve:

• Registering with the concerned DISCOM
• Completing applicable vendor registration
• Submitting business and technical documents
• Meeting financial or technical eligibility conditions
• Following project and installation requirements

Check the requirements applicable to your state and the specific solar program before applying.

Step 5: Establish Supply Chain Partnerships with Certified Manufacturers

Build partnerships with reliable solar manufacturers and authorized distributors before accepting regular customer orders. Source essential components such as:

• Solar modules
• Inverters
• Mounting structures
• Cables
• Batteries, where required
• Other electrical components

Compare suppliers based on product quality, pricing, warranty coverage, delivery timelines, and replacement support . Do not choose a supplier solely on purchase price.

Step 6: Build Your Technical Workforce and Procure Equipment

Hire electricians, solar technicians, and installers according to your expected project volume. Your team should understand site assessment, system sizing, mounting, wiring, inverter installation, testing, and safety procedures. Purchase the tools required for your projects, including:

• Electrical testing instruments
• Installation tools
• Safety equipment
• Ladders and access equipment
• Protective gear

Keep your equipment aligned with the type and scale of installations you undertake.

Step 7: Execute Local Sales and Lead Generation Strategies

Start marketing within the customer segment you selected during your market research. Build a local presence through a professional website, Google Business Profile, referrals, customer reviews, and direct outreach. Your sales process should clearly explain:

• Recommended system capacity
• Estimated electricity generation
• Installation cost
• Warranty terms
• Expected savings
• Applicable subsidy or net-metering process

Track inquiries, quotations, follow-ups, and conversions so you can identify which sales channels generate actual customers.

The cost to start a solar panel business in India typically ranges from ₹2 lakh to ₹50 lakh or more, depending on your business model and scale. An installation-focused business needs less capital than distribution, while manufacturing requires significantly higher investment.

For businesses that install rooftop systems, the installed solar system cost also affects your working capital requirement. In 2026, a typical on-grid rooftop system can cost around ₹55,000–₹85,000 per kW before subsidy , although larger commercial systems can cost less per kW because of economies of scale. Actual project costs vary with equipment quality, site conditions, system size, and installation scope.

Your initial investment can broadly include:

• Small-scale (e.g., Solar Dealer/Installer): You might start with ₹2-5 lakhs. This would cover basic office setup, initial stock or demo units, tools, basic marketing, and working capital.
• Medium-scale (e.g., Distributor or Larger Installation Firm): This could range from ₹10-50 lakhs. It would involve warehousing, a larger team, more sophisticated equipment, and a bigger marketing budget.
• Large-scale (e.g., Manufacturing): Starting a solar panel manufacturing business requires substantial capital, easily running into crores of rupees (₹1 crore) for machinery, land, and extensive operations.

Key cost factors include office/warehouse rent, inventory (panels, inverters, and batteries), tools and equipment, staff salaries, marketing, licenses, and working capital.

India’s rooftop solar market continues to expand, and the IMARC Group expects the India rooftop solar panel market to reach USD 4.5 billion by 2034. Government schemes also create opportunities for installers, manufacturers, and other businesses across the solar value chain:

• PM Surya Ghar Muft Bijli Yojana: This scheme provides Central Financial Assistance (CFA) to eligible residential consumers installing rooftop solar systems. The current CFA provides ₹30,000 per kW for the first 2 kW and ₹18,000 for the additional 1 kW , with the maximum central subsidy capped at ₹78,000 . This subsidy goes to the consumer rather than the vendor, so installers should account for the working-capital gap between installation and subsidy disbursement.
• PM-KUSUM Scheme: This scheme creates opportunities in agricultural solar projects by supporting the installation of solar pumps and the solarisation of existing grid-connected agricultural pumps. Solar businesses can explore eligible opportunities under its different components, subject to the applicable state-level implementation rules.
• Production Linked Incentive (PLI) Scheme: The government uses the PLI scheme to support domestic manufacturing of high-efficiency solar PV modules. Manufacturers that meet the applicable eligibility and performance conditions can access incentives under the scheme.
• State-specific Policies: State governments and DISCOMs may provide additional incentives, procedures, or support for rooftop solar projects. Check the applicable state policy before quoting a customer because these provisions can affect project costs and timelines.

Check ALMM Requirements Before Choosing Solar Modules

The Approved List of Models and Manufacturers (ALMM) plays an important role in government-supported solar projects. MNRE requires eligible solar PV modules to come from models and manufacturers included in ALMM List-I for government projects, government-assisted projects, and projects under government schemes and programs.

For an installer participating in PM Surya Ghar , module eligibility can directly affect the customer's subsidy. You should therefore verify the manufacturer's current ALMM listing before purchasing modules for eligible projects. Using a module that does not meet the applicable requirements can prevent the project from receiving the associated government financial assistance.

Starting a solar business can offer strong opportunities, but you must prepare for several practical challenges:

• High Initial Investment: Inventory, tools, vehicles, staff, and equipment can require substantial capital. Start with a business model that matches your available budget and expand as sales increase.
• Strong Market Competition: Established solar companies can make customer acquisition difficult. Compete through reliable products, skilled installation, transparent pricing, and responsive service instead of focusing only on lower prices.
• Shortage of Skilled Technicians: Solar installations require proper electrical and technical knowledge. Hire qualified electricians and train technicians in installation, testing, and safety procedures.
• Changing Policies and Regulations: Government programs, subsidy rules, and DISCOM procedures can change over time. Check official requirements regularly before accepting projects or promising customers specific benefits.
• Supply Chain Problems: Delays or poor-quality panels, inverters, and other components can affect installation. Choose a dependable supplier and verify warranty terms before placing orders.

Establishing a solar panel business can be a practical opportunity if you choose the right business model and understand your local market. Start with the services you can manage well, complete the required registrations, and choose suppliers who provide reliable products and warranty support. As you gain customers, focus on proper installation and timely service. These basics can help you build a trusted solar business and expand it over time.
