The one-line difference
DCR = the cells inside were made in India. Non-DCR = the cells were imported (the module may still be assembled in India).
When you must use DCR
| Project type | DCR required? |
|---|---|
| Home system with PM Surya Ghar subsidy | Yes |
| Housing society / RWA with subsidy | Yes |
| Home system without subsidy | No |
| Commercial or industrial rooftop | No |
Price and value
DCR modules carry a price premium per watt because domestic cell capacity is still growing. For a home, the subsidy (₹30,000 per kW for the first 2 kW, ₹18,000 for the third) outweighs the premium many times over, so DCR is the obvious choice. For a factory without subsidy, non-DCR modules usually give a lower cost per kWh.
Does DCR perform differently?
Performance depends on the cell technology (PERC, TOPCon, bifacial), not the country of manufacture. Compare datasheets: efficiency, temperature coefficient, degradation and warranty. See solar panel types.
How to verify DCR modules
- The module should be listed by the manufacturer as DCR and on the ALMM list.
- Your invoice and the subsidy documentation will show module serial numbers.
- We share serial numbers and DCR certificates with every subsidised installation.
