India’s rooftop solar industry is undergoing a major transformation in 2026. If you are planning a commercial rooftop solar installation, industrial rooftop solar project, factory solar plant, or large-scale C&I rooftop solar system, understanding the latest DCR vs Non-DCR solar panel regulations is now essential.
Compare Solar EPC ContractorsFrom June 1, 2026, the Government of India has significantly tightened regulations around rooftop solar installations by restricting the use of Non-DCR solar panels for most commercial, industrial, and government-supported projects.
This policy aims to strengthen domestic solar manufacturing, reduce import dependency, and support the Make in India initiative. However, for project owners, EPC contractors, builders, factories, and industries, this also means:
In this complete guide, we explain everything businesses need to know about DCR vs Non-DCR solar panels in 2026, including policy updates, cost impact, subsidy rules, ALMM compliance, and how SQFTZ helps businesses compare rooftop solar quotations.
Understanding the difference between DCR and Non-DCR solar panels is the first step before planning any commercial rooftop solar or industrial rooftop solar project.
DCR (Domestic Content Requirement) solar panels are manufactured using:
These panels comply with government-backed domestic manufacturing policies and qualify for many subsidy-linked solar projects.
Non-DCR solar panels use imported solar cells or imported modules. Historically, these panels were cheaper and widely used for commercial rooftop solar projects because of their affordability and availability.
| Feature | DCR Solar Panels | Non-DCR Solar Panels |
|---|---|---|
| Cell Manufacturing | India | Imported |
| Government Compliance | Yes | Limited |
| Subsidy Eligibility | Eligible | Mostly Ineligible |
| ALMM Requirement | Mandatory | Restricted |
| Price | Higher | Lower |
| Usage After June 2026 | Allowed | Mostly Restricted |
| Best For | Future-ready projects | Projects registered earlier |
India’s solar market has relied heavily on imported solar components for years. To strengthen domestic manufacturing and reduce import dependency, the Ministry of New and Renewable Energy (MNRE) has enforced stricter DCR and ALMM requirements.
After June 1, 2026:
Official Government Resources:
The government has established strict timelines for projects using Non-DCR solar panels.
| Timeline | Date |
|---|---|
| Registration Deadline | March 31, 2026 |
| Commissioning Deadline | May 31, 2026 |
Projects that fail to meet these timelines must shift to DCR-only panels for compliance.
From June 1, 2026 onward, new commercial and industrial rooftop solar projects using Non-DCR modules may not qualify under updated government rules.
One of the biggest concerns for industries and commercial building owners is the increase in solar installation costs due to DCR compliance.
DCR panels may increase rooftop solar project costs by ₹8,000–₹10,000 per kW.
Limited domestic manufacturing capacity and increased demand are pushing DCR panel pricing upward.
Businesses may also face longer procurement timelines and EPC scheduling delays.
| System Size | Additional Estimated Cost |
|---|---|
| 10 kW | ₹80,000 – ₹1,00,000 |
| 50 kW | ₹4 – ₹5 Lakhs |
| 100 kW | ₹8 – ₹10 Lakhs |
ALMM stands for Approved List of Models and Manufacturers.
The Government of India now requires many commercial and industrial rooftop solar projects to use modules listed under ALMM compliance standards.
ALMM ensures:
Projects using non-compliant modules may face:
Under the PM Surya Ghar: Muft Bijli Yojana, DCR compliance is now highly important.
DCR solar panel prices are expected to rise further as demand increases.
Domestic manufacturers may experience temporary supply shortages.
Experienced rooftop solar EPC contractors may become fully booked.
Wrong module selection can create approval and commissioning problems.
In 2026, EPC expertise matters more than ever. A reliable solar EPC company helps businesses with:
Poor planning can cost significantly more than the difference between DCR and Non-DCR panel pricing.

India’s rooftop solar industry is rapidly moving toward:
The 2026 DCR policy is expected to accelerate India’s local solar manufacturing ecosystem and create a more reliable rooftop solar industry for the future.
The 2026 DCR policy update is one of the most important regulatory changes for India’s rooftop solar market in recent years.
Businesses planning commercial rooftop solar or industrial rooftop solar projects can no longer ignore:
Companies that plan early will gain the biggest advantage in terms of pricing, compliance, and execution certainty.
If your rooftop solar project is still in the planning stage, now is the right time to:
DCR solar panels use India-manufactured cells and modules, while Non-DCR panels use imported components.
Non-DCR panels are heavily restricted for many commercial, industrial, and government-supported rooftop solar projects after June 1, 2026.
Yes. Industry estimates suggest DCR panels may increase rooftop solar project costs by ₹8,000–₹10,000 per kW.
Yes. Many rooftop solar projects now require ALMM-approved modules for compliance and approvals.
In some cases yes, but they may need to give up subsidy benefits under PM Surya Ghar schemes.
The government aims to strengthen domestic solar manufacturing and reduce import dependency.
Businesses should work with experienced EPC contractors, verify ALMM-approved modules, and plan projects early.
Yes. For most new commercial, industrial, and government-supported rooftop solar projects in India, Non-DCR solar panels are effectively discontinued after May 31, 2026. Projects commissioned after this deadline are generally required to use DCR-compliant solar panels under updated MNRE and ALMM regulations.
In most commercial and industrial rooftop solar projects, Non-DCR panels will no longer be permitted after May 31, 2026. However, certain residential or non-subsidy projects may still have limited flexibility depending on government rules and project category. Businesses should always verify the latest MNRE and ALMM compliance requirements before procurement and installation.
