Approved List of Models and Manufacturers for Solar PV Modules & Inverters in India
ALMM (Approved List of Models and Manufacturers) is a mandatory list published by the Ministry of New and Renewable Energy (MNRE), Government of India, under the provisions of the Solar Photovoltaics, Systems, Devices, and Components Goods (Requirements for Compulsory Registration) Order, 2017.
The ALMM includes all models and manufacturers of solar photovoltaic (PV) modules, inverters, and other solar components that are eligible for use in government-sponsored solar projects, subsidy schemes, and net-metering installations in India.
Ensures only high-quality, reliable solar modules are deployed in India's solar projects, preventing premature degradation and performance issues.
Encourages domestic solar manufacturing by mandating local production for government projects.
Protects consumers and project developers from substandard imported solar products.
Enables tracking of module performance and facilitates warranty enforcement.
January 2019 - MNRE issued the Solar Photovoltaics, Systems, Devices, and Components Goods (Requirements for Compulsory Registration) Order, 2017, establishing ALMM.
April 2021 - ALMM became mandatory for all government-sponsored solar projects, including those under CPSU scheme, PM-KUSUM, and rooftop solar installations availing subsidies.
Crystalline Silicon (Mono/Poly), Thin-Film modules of all capacities
For domestic content requirement (DCR) projects
String inverters, central inverters, micro-inverters
Solar batteries and energy storage systems
Manufacturers wanting to sell modules for government projects must get ALMM registration
Must use only ALMM-listed modules for government-sponsored solar projects
Contractors executing government solar projects must procure ALMM-listed modules
While foreign manufacturers can get ALMM enlistment, only modules manufactured in India are eligible for Domestic Content Requirement (DCR) projects. Imported modules may only be used in Open Category projects.
Submit module samples to MNRE-approved laboratory (NISE, TERI, CPRI, etc.) for testing as per IEC/BIS standards.
Prepare and compile all required documents including manufacturing details, quality management system certificates, and technical specifications.
Submit online application to NISE along with test reports and required documents. Pay applicable fees.
NISE officials review application, verify documents, and conduct factory inspection/audit.
Upon approval, manufacturer and module models are added to ALMM. Total timeline: 4-6 months.
