As high-power-consuming industries look to cut electricity costs and meet ESG goals without heavy upfront capital, this model is becoming central to how corporate India sources power.
India’s policy environment is turning increasingly favourable for this segment. The Ministry of New and Renewable Energy (MNRE) reports that India added a record 44.5 GW of renewable energy capacity in 2025, while Green Open Access Rules, banking provisions, and renewable purchase obligation (RPO) compliance are simplifying procedures and expanding the addressable market. Rising participation from independent power producers, green energy developers, and digital energy platforms is creating a more competitive and efficient ecosystem, making India a strategically sound base for this kind of production.
This investment combines regulatory tailwinds, growing renewable purchase obligations, and rising corporate sustainability commitments with healthy gross margins of 14-22% and net margins of 5-10%. With demand concentrated across manufacturing, data centers, infrastructure, and telecom, and with capacities scalable from 500 MW to 2 GW, the segment offers a financially sound and policy-supported entry point for investors evaluating break-even viability.
What is Solar Open Access?
Solar open access is a regulatory mechanism that allows large electricity consumers, usually industries, to buy power directly from offsite solar developers rather than local utility monopolies. Instead of installing panels on their own premises, businesses sign a Power Purchase Agreement (PPA) to source clean energy wheeled through the existing state grid, paying the developer the agreed tariff plus regulated grid charges. This model offers major cost savings and helps consumers meet ESG goals without upfront capital investments.
The solar open access manufacturing process centers on solar power generation, electricity transmission through dedicated connectivity, power scheduling, metering, and grid integration. The end-use base for this production is broad, spanning manufacturing, commercial and industrial facilities, data centers, infrastructure, telecommunications, and other high-power-consuming industries.
Cost of Setting Up a Solar Open Access Manufacturing Plant in India
The cost of setting up a solar open access manufacturing plant depends on capacity, technology, location, automation, and regulatory compliance.
1. Capital Expenditure (CapEx)

2. Operational Expenditure (OpEx)
Raw material cost is the single largest component of OpEx, accounting for approximately 65-75% of total operating expenses. Key raw materials include high-purity silicon, silver paste, copper ribbon/busbars, low-iron tempered glass, EVA/POE encapsulant film, polymer backsheet, aluminium frame, and junction box. Given this weight in the cost structure, securing long-term contracts with reliable suppliers is essential to mitigate price volatility and ensure a consistent supply of materials for the solar open access manufacturing plant.
Utility cost, covering electricity, water, and steam, accounts for approximately 8-12% of OpEx. Other operating costs for the plant include transportation, packaging, salaries and wages, depreciation, taxes, and repairs and maintenance, all of which factor into the first-year operating cost base. By the fifth year of operations, total operational cost is expected to increase substantially due to inflation, market fluctuations, potential rises in the cost of key materials, supply chain disruptions, and rising consumer demand.
3. Plant Capacity
The proposed solar open access manufacturing facility is designed with an annual capacity ranging between 500 MW and 2 GW, enabling economies of scale while maintaining operational flexibility. Plant capacity can be customized based on investor requirements, and profitability of the unit improves with higher capacity utilisation.
4. Profit Margins and Financial Projections
Financial projections for a solar open access manufacturing plant are built on capital investment, operating costs, capacity utilisation, pricing trends, and demand outlook, and cover liquidity analysis, profitability, payback period, net present value (NPV), and internal rate of return (IRR). Under normal operating conditions, the project demonstrates healthy profitability, with gross profit margins typically ranging between 14-22% and net profit margins between 5-10%.
