India's solar manufacturing base has scaled up sharply over the last two years, driven by the Production Linked Incentive (PLI) scheme, the Approved List of Models and Manufacturers (ALMM), and rising domestic demand for rooftop and utility-scale solar. For buyers in Kerala, the choice of manufacturer usually comes down to one key question: do you need a DCR panel to claim a subsidy, or can you install a Non-DCR panel for a private, subsidy-free system? This guide breaks down both categories and ranks the manufacturers worth shortlisting in 2026.
DCR vs Non-DCR — What's the Real Difference?
DCR stands for Domestic Content Requirement. A panel earns DCR status only when both the solar cells and the finished module are manufactured in India, following Ministry of New and Renewable Energy (MNRE) norms. Non-DCR panels, by contrast, are typically assembled using imported cells — often sourced from China or Southeast Asia — even if final assembly happens on Indian soil.
✔ DCR Panels
- Solar cells and modules made entirely in India
- Mandatory for subsidy-linked schemes: PM Surya Ghar, PM-KUSUM (Components B & C), CPSU Phase-II
- Required for most state rooftop subsidy programs, including Kerala's ANERT-routed schemes
- Slightly higher upfront cost, offset by the subsidy
✔ Non-DCR Panels
- Use imported cells; assembly may or may not be in India
- No restriction on subsidy-free private, commercial, or industrial installations
- Often competitively priced due to large-scale global manufacturing
- Not eligible for central or most state subsidy payouts
In short: if you're applying for the central rooftop subsidy in Kerala, your installer must quote DCR-listed modules. If you're funding the system privately with no subsidy claim, Non-DCR panels remain a valid and sometimes more cost-effective option.
