The Ministry of New and Renewable Energy (MNRE) released a Gazette notification on January 27, 2025, titled “Solar Systems, Devices and Components Goods Order, 2025“, updating the standards for existing products. While no new products have been introduced, this update applies to all five existing products and will come into effect 180 days (26 July 2025) from the date of publication.
Changes in India Standard:
The existing product will validity remains unaffected while the new application and renewal of the application have to comply with the new Indian standards as below:

Condition of grant of licence: To grant of licence under this Order, a condition is introduced to set minimum efficiency (@ Standard Test Conditions i.e., STC) criteria.
- Mono Crystalline Silicon Terrestrial Photovoltaic (PV) modules (Si wafer-based) technology & Thin-Film Terrestrial Photovoltaic (PV) Modules [Cd Te, a-Si, Cu(In, Ga)(S, Se)2] technology: Minimum efficiency 18%
- Poly Crystalline Silicon Terrestrial Photovoltaic (PV) modules (Si wafer-based) technology: 17%
Efficiency Calculation Formula:
The formula for calculating the efficiency (@ STC in %) of a Solar PV module is:
efficiency(@STC%) = (1000×A (in m²) Pmax (in Watts) ×100
Where:
- Pₘₐₓ = Maximum power output of the module (in Watts)
- A = Area of the front surface of the module (in m²)
- 1000 = Solar irradiance at Standard Test Conditions (STC) in W/m²
This formula ensures that the module’s power efficiency is evaluated under standardized conditions as per IS 14286.
