A step-by-step 2026 guide for founders starting a solar or renewable energy company in India — structure, licenses, SPV setup, documents, costs, and incentives.
How to Start a Solar & Renewable Energy Company in India (2026 Step-by-Step Guide)
India's push toward clean energy has created a genuine gold-rush moment for entrepreneurs — from rooftop solar installers to utility-scale developers to companies supplying EPC (engineering, procurement, construction) services. But the renewable energy sector is not like a typical startup: it involves land, long-term power purchase agreements, project financing, and multiple regulatory approvals that founders coming from a pure-business background often underestimate.
If you are planning to set up a solar or renewable energy company in India, getting the legal structure right from day one is not optional — it directly affects your ability to raise project debt, sign PPAs (power purchase agreements), and bid for government tenders. This guide breaks down the entire process so you can move from idea to an incorporated, compliant, bankable entity.
Why Solar & Renewable Energy Is a Massive Opportunity Right Now
- National renewable energy targets continue to drive strong policy support, tenders, and incentives for solar, wind, and hybrid projects across central and state governments.
- Falling module and battery storage costs have made solar increasingly competitive against conventional power, opening up commercial and industrial (C&I) rooftop and open-access markets.
- Rooftop and distributed solar demand is growing fast among housing societies, factories, and commercial establishments looking to cut electricity bills and meet ESG commitments.
- PM Surya Ghar and similar rooftop solar schemes are expanding the addressable residential market for installers and EPC companies.
- Corporate ESG and RE100 commitments are pushing large corporates to sign long-term PPAs with renewable energy developers, creating steady project pipelines.
- Green financing availability — banks, NBFCs, and green bonds are increasingly channelling capital toward renewable energy projects, making it easier for well-structured companies to raise debt.
Whether you want to be a rooftop solar installer, an EPC contractor, a project developer building solar/wind farms, or a company supplying equipment and O&M (operations & maintenance) services, the sector rewards founders who set up the right legal and financial structure early.
Best Business Structure for a Solar/Renewable Energy Company
Private Limited Company (Pvt Ltd) — This is the standard and recommended structure for almost all renewable energy businesses, whether you are doing EPC/installation work or developing your own projects. Reasons:
- Banks and NBFCs prefer lending to Pvt Ltd companies for project finance and equipment loans
- Limited liability protects founders from project-related risks (a real concern given the scale of capital involved)
- Easier to bring in investors, private equity, or infrastructure funds later
- Required structure for signing PPAs with discoms, corporates, or government agencies in most tenders
Project SPV (Special Purpose Vehicle) — For renewable energy developers, it is standard industry practice to set up a separate Pvt Ltd company (an SPV) for each individual project or project cluster, rather than running all projects under one parent company. This is done because:
- Lenders financing a specific solar/wind project want that project's cash flows and assets ring-fenced from your other projects
- It isolates risk — if one project underperforms or faces litigation, your other projects and parent company are protected
- It simplifies eventual sale or refinancing of a single project to another investor or fund
- Most PPAs and tenders are structured around a single SPV holding a single project
LLP — Occasionally used for smaller O&M, consulting, or trading businesses within the renewable space where funding and project financing are not central, but LLPs are rarely used for actual project development because lenders and PPA counterparties generally require a company structure.
Our recommendation: Set up a parent Pvt Ltd company to run your core business (EPC, sales, O&M, corporate functions), and create individual project SPVs (also Pvt Ltd) under it for each solar/wind/hybrid project you develop. If you are only doing rooftop installation or EPC contracting work without owning projects yourself, a single Pvt Ltd company is usually sufficient.
Registrations, Licenses & NIC Code You Need
- Company/SPV incorporation with MCA via SPICe+
- NIC Code: Renewable energy businesses generally fall under codes relating to "electric power generation using renewable sources," "solar power generation," or "installation of electrical equipment," depending on whether you generate power, install systems, or provide EPC/consulting services — confirm the precise applicable code with your CS at the time of filing.
- GST Registration — mandatory for supply of goods (solar panels, inverters, batteries) and services (installation, EPC, O&M); note that GST rates for solar equipment and related services have specific classifications, so get this checked carefully.
- MNRE/State Nodal Agency registration — most states have a designated renewable energy nodal agency (for example, state renewable energy development agencies) where developers and installers often need to register or empanel to participate in subsidy schemes and net-metering programs.
- Net Metering/Grid Connectivity approval — required from the local discom for rooftop and distributed solar projects before commissioning.
- Power Purchase Agreement (PPA) — for larger projects selling power to discoms, corporates, or through open access, a PPA is the core commercial document, often tied to tender conditions.
- Environmental clearances — larger ground-mounted solar/wind projects may need environmental and land-use clearances depending on project size and location; smaller rooftop projects typically do not.
- Electrical Safety/Contractor License — installation and EPC companies often need an electrical contractor license or certified electrical supervisor on their team as per state electricity rules.
- Empanelment with MNRE/state agencies — useful for participating in subsidy-linked rooftop solar schemes like PM Surya Ghar.
- Import Export Code (IEC) — needed if you import solar panels, inverters, or components, or plan to export equipment/services.
Documents Required
- PAN and Aadhaar of all directors/partners and shareholders
- Address proof and photographs of directors
- Registered office address proof and NOC from the property owner
- Land documents or lease/PPA-linked site agreements (for project SPVs — ownership or long-term lease of the project site)
- DSC (Digital Signature Certificate) for all directors
- MOA/AOA drafts covering power generation, EPC, trading, and O&M activities
- Technical qualifications/certifications of key personnel (especially for electrical contractor licensing)
- Financial projections and project reports (needed later for project financing and lender due diligence)
- Board resolutions and shareholding agreements (particularly important when setting up multiple project SPVs)
Step-by-Step: From Idea to Incorporated & Compliant
- Decide your business model — EPC/installation services, rooftop solar sales, or independent project development (which requires the SPV structure).
- Choose your structure: a parent Pvt Ltd for the core business, plus project-specific SPVs (also Pvt Ltd) if you are developing your own solar/wind assets.
- Reserve your company name(s) through the MCA portal, keeping naming consistent if you plan multiple SPVs (e.g., "ABC Solar Project 1 Pvt Ltd," "ABC Solar Project 2 Pvt Ltd").
- Obtain DSC and file SPICe+ for incorporation, PAN, and TAN.
- Register for GST, ensuring correct classification of solar goods versus services for accurate tax treatment.
- Register with your state's renewable energy nodal agency and check empanelment requirements for subsidy schemes if doing rooftop/residential work.
- Secure land or site agreements for project SPVs — ownership, lease, or usage rights must be clearly documented before you can apply for grid connectivity or bid for tenders.
- Apply for grid connectivity/net metering approval with the local discom for the specific project.
- Sign the PPA with the relevant counterparty (discom, corporate buyer, or through an open-access arrangement), following tender or bilateral negotiation processes.
- Arrange project financing — approach banks, NBFCs, or green financing institutions; having a clean SPV structure and complete documentation significantly speeds up loan approval.
- Complete installation, commissioning, and safety certifications, then begin operations and revenue generation.
- Set up ongoing compliance — ROC annual filings for each entity, GST returns, TDS, and O&M/asset-tracking records, since multiple SPVs mean multiple sets of annual compliance.
Cost & Fees 2026
Costs depend heavily on project scale, state, and whether you are forming a single company or multiple SPVs. As a general guide (always verify the current rate before paying, since fees and subsidy rates are revised periodically):
- Incorporation cost per Pvt Ltd/SPV: Government fees vary by state and authorised capital; professional fees vary by service provider and package.
- DSC per director: A modest per-director cost, usually valid for 1-2 years.
- GST registration: No government fee, but professional assistance is commonly charged.
- Nodal agency registration/empanelment fees: Vary by state and scheme.
- Electrical contractor license: State-specific fees and renewal costs.
- Land/lease documentation and stamp duty: Highly variable depending on state and land size — a major cost component for utility-scale projects.
- Project financing processing fees: Charged by banks/NBFCs as a percentage of loan amount, varying by lender.
Because renewable energy project costs, subsidy amounts (like under PM Surya Ghar), and state-specific fees change frequently, always confirm current figures with your consultant or the relevant nodal agency before committing capital.
Tax & Incentives
- Accelerated depreciation — Renewable energy assets have historically been eligible for accelerated depreciation benefits under the Income Tax Act, which significantly improves early-year cash flows for project owners; confirm the current applicable rate with your CA as depreciation schedules are periodically revised.
- Concessional customs duty on specified renewable energy equipment — Certain solar/wind components may attract concessional import duties depending on current government notifications; verify applicability for your specific equipment.
- PM Surya Ghar and rooftop subsidy schemes — Residential and certain commercial rooftop solar installations may be eligible for central/state subsidies, which installers can help customers access, indirectly boosting sales.
- DPIIT Startup India recognition and Section 80-IAC — If your renewable energy company qualifies as an innovative startup (for example, a cleantech or energy-tech company solving genuine technical problems, not just a standard EPC business), you may be eligible for startup tax benefits — this is more relevant for renewable-energy technology/software startups than pure project SPVs.
- State solar/renewable energy policies — Many states offer additional incentives such as electricity duty exemption, banking of power, and easier land allotment for renewable energy projects — check your state's current policy document.
- GST input tax credit — Careful structuring of goods and services procurement can help optimise GST input credit for large capex projects.
Common Mistakes
- Running multiple projects under one company instead of separate SPVs, which complicates lender due diligence and increases risk exposure across your entire portfolio.
- Starting land acquisition or PPA negotiations before incorporating the SPV, causing delays and legal complications in transferring agreements to the company.
- Underestimating the licensing timeline for grid connectivity, net metering, and nodal agency approvals — these often take longer than the incorporation itself.
- Ignoring GST classification nuances between goods (panels, inverters) and services (installation, EPC), leading to incorrect invoicing and input credit issues.
- Not verifying land title and clearances thoroughly before committing capital — land disputes are one of the most common causes of project delays in this sector.
- Missing state-specific subsidy application deadlines for rooftop solar schemes, resulting in lost customer incentives and reduced competitiveness.
- Neglecting O&M and safety compliance post-installation, which can lead to penalties or safety incidents affecting your company's reputation and licenses.
FAQ
Do I need a separate company for every solar project I develop?
It is standard industry practice to set up a separate SPV (Special Purpose Vehicle), usually a Pvt Ltd company, for each individual project or project cluster. This isolates project-specific risk and is generally required by lenders financing the project.
What is the best business structure for a rooftop solar installation company?
A single Private Limited Company is usually sufficient if you are only doing installation, EPC, and O&M services without owning large-scale generation assets yourself. The SPV structure becomes important mainly for independent project developers.
Do I need MNRE approval to start a solar company?
Direct MNRE approval is not typically required to incorporate a company, but registration or empanelment with your state's renewable energy nodal agency is often necessary to participate in subsidy schemes, tenders, and net-metering programs.
What licenses are needed for rooftop solar installation?
Common requirements include GST registration, net metering/grid connectivity approval from the local discom, and often an electrical contractor license or a certified electrical supervisor associated with your company, depending on state electricity rules.
Can a startup in renewable energy get Section 80-IAC tax benefits?
It depends on whether your business qualifies as an eligible "startup" under DPIIT norms — generally more applicable to renewable energy technology or innovation-driven businesses rather than standard EPC or project development companies. Check eligibility criteria carefully with your CA.
How is GST applied to solar power projects?
GST treatment differs for solar equipment supply versus installation/EPC services, and specific solar-sector GST rates and valuation rules apply. Given the complexity and periodic rate revisions, it is best to get project-specific GST advice before quoting or invoicing clients.
How long does it take to get grid connectivity for a rooftop solar project?
Timelines vary significantly by state and discom, often ranging from a few weeks to a couple of months depending on documentation completeness and local processing capacity — always check current discom-specific timelines.
Is land ownership required to develop a solar project, or can I lease it?
Both models are common — some developers purchase land outright, while many use long-term lease agreements for the project site. Either way, clear title and proper documentation are essential before applying for approvals or financing.
