The Government of India’s PM Surya Ghar Muft Bijli Yojana has created one of the largest demand spikes in the residential solar market in recent history. With a target of electrifying 1 crore households with free solar power by 2027 and subsidies of up to ₹78,000 per household, solar distributors, sellers, and installers operating in this scheme are under immense pressure to source panels that meet strict technical and regulatory requirements.

This guide breaks down every critical technical criterion that solar panels must satisfy to be eligible under the scheme — and how to partner with the right solar cell and module manufacturer in India to stay consistently compliant.

Understanding PM Surya Ghar Muft Bijli Yojana at a Glance

Launched in February 2024, the PM Surya Ghar Muft Bijli Yojana is designed to enable Indian households to install rooftop solar systems of 1 kW to 3 kW capacity and above. The subsidy structure is as follows: ₹30,000 per kW for systems up to 2 kW, ₹18,000 per kW for the third kW, capping at ₹78,000 for 3 kW and above. Beneficiaries can apply through the National Portal for Rooftop Solar at pmsuryaghar.gov.in.

For installers and distributors, compliance with the Ministry of New and Renewable Energy (MNRE) norms — particularly the Approved List of Models and Manufacturers (ALMM) — is not optional. Panels sourced from non-ALMM manufacturers are ineligible for subsidy disbursement, making manufacturer selection a business-critical decision.

The ALMM Compliance Requirement: What Distributors Must Know

The Approved List of Models and Manufacturers (ALMM) is maintained by MNRE and lists solar PV modules certified for use in government-funded solar projects including PM Surya Ghar. To appear on this list, a manufacturer must pass Bureau of Indian Standards (BIS) certification and meet performance benchmarks under IEC 61215 and IEC 61730 standards.

Distributors and installers must always verify that the solar panels they procure appear on the current ALMM list, available at mnre.gov.in. The list is updated quarterly, and any module delisted between order and installation can jeopardise subsidy disbursement.

Key Technical Benchmarks for Panel Eligibility

1. Module Efficiency Standards

MNRE mandates minimum module efficiency levels for subsidised installations. For crystalline silicon (c-Si) modules — which form the backbone of most residential solar installations — the minimum efficiency threshold is typically 19.5% and above for Mono PERC and higher-tier technologies. As a distributor, sourcing panels from a manufacturer using M10 wafer-based Mono-PERC or bifacial cells ensures you are well above the minimum bar.

Understanding the technical differences between cell technologies helps you make informed procurement decisions. Explore our detailed breakdown of MonoPERC, N-Type, and M10 cell technologies at our MonoPERC vs N-Type vs M10 guide to choose the right technology for residential rooftop applications.

2. Temperature Coefficient and Performance in Indian Climates

India’s diverse climate — from humid coastal belts to scorching plains — demands panels with a low temperature coefficient of power (Pmax). A coefficient better than -0.35%/°C is preferred. M10 Mono-PERC bifacial cells perform exceptionally well in high-irradiance, high-temperature conditions typical across India’s solar belt, offering consistent output even as ambient temperatures exceed 40°C.

3. Durability and Warranty Requirements

MNRE-backed scheme installations require modules with at least a 25-year linear power output warranty and a minimum 10-year product warranty. Installers should request manufacturer warranty certificates during procurement and maintain these for audit purposes, as DISCOMs may verify these documents during subsidy processing.

Choosing the Right Manufacturer: Compliance + Capacity

Sourcing panels from a verified domestic solar cell and module manufacturer in India not only ensures ALMM compliance but also supports the government’s Atmanirbhar Bharat manufacturing push. Under the Domestic Content Requirement (DCR) provisions in certain government tenders, domestically manufactured modules are mandatory.

At Websol Energy System, as a leading solar cell manufacturer in India, we manufacture M10 Bifacial Mono-PERC solar cells certified to international quality standards — a technology ideal for the residential and small commercial segments targeted under PM Surya Ghar.

Our solar module manufacturer in India capabilities ensure end-to-end traceability from cell to finished module, with documentation ready for ALMM audit requirements.

Installation Best Practices for Subsidy Disbursement

Even compliant panels can result in subsidy delays if installation standards are not followed. MNRE requires that all PM Surya Ghar installations are connected to the grid through a net-metering arrangement with the local DISCOM. Installers must use approved grid-tie inverters, properly size the system based on the sanctioned load, and submit all documents — including module specifications, ALMM certificates, and installation photographs — through the national portal.
