How to Start a Solar EPC Business in India: Step-by-Step Guide

Starting a solar epc business in India requires company registration, MNRE empanelment, compliant solar panel sourcing, mounting structure planning, and net metering coordination. Businesses entering this sector should establish documented processes for procurement, project execution, technical compliance, and financial management before undertaking client projects.

What Is a Solar EPC Business and What Services Does It Cover?

A solar epc business manages the engineering, procurement, and construction activities involved in setting up solar power systems. EPC firms generally oversee project planning, equipment sourcing, installation, testing, and commissioning.

Unlike operations and maintenance vendors, EPC contractors are responsible for complete project execution from design through grid connectivity.

The scope of solar project management commonly includes the following activities:

A solar rooftop business may work on residential, commercial, industrial, or institutional projects. Many new EPC firms begin with rooftop installations because they generally require lower operational scale than utility-grade projects.

Legal Registration and MNRE Empanelment: The First Steps

Setting up a solar epc business in India involves registration, taxation, and electricity‑related compliance requirements, depending on project type and scale.

The process may include:

1. Business Incorporation – Registration as a Private Limited Company or LLP through the MCA portal.

1. MSME Udyam Registration – Eligible entities may apply to access applicable MSME schemes.

1. GST Registration – GST registration may apply where EPC activities involve taxable supply of goods or services, subject to prevailing tax regulations.

1. Electrical Contractor Licence – Electrical installation activities are typically required to be supervised by licensed personnel under applicable state rules.

1. MNRE / DISCOM Empanelment – Participation in government‑supported or DISCOM‑linked programmes may require empanelment or approval, depending on the scheme.

Documents Required for MNRE Empanelment

The following documents are commonly required during the empanelment process:

• Certificate of Incorporation or LLP registration

• PAN card of the company

• GST registration certificate

• Audited balance sheets for the previous two financial years

• Electrical Contractor Licence

• Experience certificates for completed solar projects, if available

• Bank solvency certificate or banker reference letter

• Technical manpower details

• Address proof and authorised signatory documents

State DISCOMs may request additional documents depending on local regulations and rooftop solar programme requirements.

Solar Panel Sourcing: How to Find ALMM-Listed Suppliers

Solar module sourcing is an important operational activity for any solar panel dealership or EPC contractor.

The Ministry of New and Renewable Energy (MNRE) maintains the Approved List of Models and Manufacturers (ALMM), which contains approved domestic solar module manufacturers for specified government-linked projects.

ALMM-listed modules are commonly required for:

• Government rooftop solar programmes

• Public sector solar tenders

• DISCOM-linked projects

• Certain subsidy-linked installations

For private commercial and industrial projects, procurement requirements may differ depending on client specifications and applicable regulations.

ALMM vs Non-ALMM Modules

Note: ALMM applicability depends on project type, commissioning date, and MNRE notifications in force at the time of installation. EPC firms should verify the latest ALMM requirements prior to procurement.

Before procurement, EPC firms should review:

• BIS certification validity

• Warranty documentation

• Technical specifications

• Supply timelines

• Distributor pricing terms

Indicative module pricing may vary based on technology type, order volume, and market conditions. Businesses operating a solar epc business should verify current pricing directly with authorised suppliers before procurement decisions.

Structure Fabrication: Mounting Systems and Civil Work

Mounting structures form the physical foundation of a solar installation.

Common structure categories include:

• Fixed-tilt GI structures for flat rooftops

• Elevated structures for industrial rooftops

• Aluminium mounting systems for lightweight applications

• Tracker-based systems for utility-scale projects

New solar rooftop business operators often begin with vendor‑supplied prefabricated structures, which may reduce in‑house fabrication requirements and inventory handling complexity, depending on project scale and procurement arrangements.

Larger EPC firms may establish in-house fabrication capability after project volume increases.

Key Civil and Electrical Components

All mounting structures should comply with applicable IS standards and wind-load requirements. Structural suitability becomes especially important in coastal and high-wind regions.

Net Metering Liaison: Getting Grid Connection Approved

Net metering is a billing mechanism that allows eligible consumers to export surplus solar electricity to the grid through a bidirectional meter, subject to applicable state regulations.

As part of solar project management, EPC contractors may coordinate the application process on behalf of clients.

The process generally includes:

1. Submission of the net metering application to the relevant DISCOM

1. Payment of the prescribed application fee

1. Technical inspection by the DISCOM

1. Installation of a bidirectional meter

1. Grid synchronisation and commissioning approval

Application fees and approval timelines vary across states, DISCOMs, and project categories.

Indicative State-Level Net Metering Comparison

For compliance and accuracy, avoid implying fixed fees, timelines, or approval processes because these vary by utility, capacity, policy updates, and application completeness. A cleaner table would be:

Note: Application fees, approval timelines, and procedures are indicative and subject to change based on DISCOM and State Electricity Regulatory Commission (SERC) updates.

State-level procedures may change periodically based on electricity regulatory updates. Businesses operating a solar rooftop business should review the latest DISCOM and SERC guidelines before submission.
