Largest Solar Panel Manufacturers in India by Capacity
Manufacturing capacity is one of the most commonly used measures when comparing solar companies. However, the largest manufacturer is not automatically the best choice for every installation.
India’s solar manufacturing industry has expanded rapidly. According to Mercom India’s State of Solar PV Manufacturing in India 2026 report, released in 2026, the country added approximately 119 GW of solar module manufacturing capacity and more than 9 GW of solar cell capacity during 2025. Cumulative module manufacturing capacity reached around 210 GW by December 2025, compared with approximately 27 GW of cell capacity.
When comparing the largest solar panel manufacturers in India, check:
- Installed module capacity: The annual volume that module production facilities are designed to manufacture.
- Operational capacity: Production facilities that are running, rather than only planned or under construction.
- Solar cell capacity: The ability to manufacture cells used in solar modules.
- Actual production: The volume produced over a particular reporting period.
- Technology: Whether the company manufactures PERC, TOPCon, HJT, or other module types.
- Certifications and eligibility: Whether the specific product meets the requirements of the intended project.
Always compare figures for the same reporting period. A company may announce a large expansion, but the announced capacity should not be treated as operational until the facility is commissioned and production is verified.
How Does Solar Panel Manufacturing Work in India?
Solar panel manufacturing involves several stages, from processing solar cells to assembling and testing the finished module. Some solar manufacturing companies produce cells and modules, while others purchase cells and focus on module assembly.
Step 1: Solar cell manufacturing
Solar cells are the main components that convert sunlight into electricity. Manufacturers process silicon-based materials into wafers and use specialised processes to create electrical properties that allow the cells to generate power.
Cell production involves several technical stages, including surface treatment, passivation, electrical contact formation, and testing. The quality of the cells influences the performance of the finished solar module.
Step 2: Cell sorting and stringing
Manufacturers test and sort the solar cells before connecting them electrically. The cells are joined into strings and arranged according to the module’s design.
Correct connections are important because defects or poor connections can reduce output and affect long-term reliability.
Step 3: Module layering and lamination
The solar cells are placed between protective layers, usually including glass and encapsulant materials. Depending on the design, the rear layer may be a backsheet or another glass layer.
The assembly passes through a lamination process that bonds the layers and protects the cells from moisture and environmental damage.
Step 4: Framing and electrical testing
Manufacturers fit the frame, junction box, and other required components. They then test the finished module for electrical performance and quality.
Testing can include power measurement, insulation checks, visual inspection, and electroluminescence testing to identify certain internal cell defects.
Step 5: Packaging and distribution
After quality checks, modules are labelled with model information and serial numbers, then packed for transportation.
Buyers should check that the supplied module model matches the purchase order, datasheet, warranty documents, and any applicable certification or approval listing.
Types of Solar Panels Manufactured in India
Different manufacturers offer different technologies. The right choice depends on roof space, budget, climate, installation design, and the project’s energy requirements.
Monocrystalline Solar Panels
These panels use cells made from single-crystal silicon. They are widely used in rooftop and commercial installations because they can offer high power output from a given area. Compare efficiency and temperature performance for the exact model.
TOPCon Solar Panels
TOPCon stands for Tunnel Oxide Passivated Contact. It is a solar cell technology designed to improve efficiency and reduce electrical losses. It is an important part of India’s newer module manufacturing capacity.
Mono PERC Solar Panels
PERC stands for Passivated Emitter and Rear Cell. These modules have been widely used in solar installations. Buyers should compare their current price and performance with newer technologies rather than assuming one type is always better.
Bifacial Solar Panels
Bifacial modules can generate electricity from both sides when the rear side receives useful reflected or scattered light. Their additional energy generation depends on ground reflectivity, mounting height, spacing, and installation conditions.
Manufacturers may also offer glass-glass and glass-backsheet designs. The construction, warranty, weight, and installation requirements should be checked for the specific product.
How to Choose the Best Solar Panel Manufacturing Company in India
Choosing a reliable solar panel manufacturing company requires more than comparing brand names or advertised wattage. Use these checks before making a purchase.
1. Check manufacturing credentials and certifications
Confirm the manufacturer’s identity, factory details, model number, and applicable product certifications. Check current BIS requirements and relevant IEC standards for the specific product.
For projects covered by India’s Approved List of Models and Manufacturers (ALMM) requirements, verify the exact model and manufacturer against the latest official list. The Ministry of New and Renewable Energy explains the purpose and applicability of ALMM on its official website.
Not every project is subject to identical requirements, so confirm the rules for your project type.
2. Compare efficiency and power output
A panel’s wattage indicates its rated power under specified test conditions. Efficiency indicates how effectively the panel converts sunlight into electricity for its surface area.
For example, higher-efficiency modules can be useful where roof space is limited. However, the best option also depends on price, temperature coefficient, shading, and the total system design.
3. Understand the warranty
Check two important types of warranty:
- Product warranty: Covers specified defects in materials or workmanship under the warranty terms.
- Performance warranty: Sets out the manufacturer’s commitments concerning power output over a stated period.
Read the exclusions, claim procedure, and warranty provider details. A long warranty period is useful only if its terms are clear and the claim process is practical.
4. Evaluate quality and traceability
Ask for the datasheet, relevant test documents, model details, serial-number information, and warranty conditions.
For large projects, also review quality assurance procedures, inspection arrangements, and the supplier’s process for dealing with defective or damaged products.
5. Compare total project cost
Do not choose a manufacturer only because its panel price is lower. The total solar project cost can include:
- Solar panels and inverter.
- Mounting structure and electrical cables.
- Protection devices and earthing.
- Installation, transport, and commissioning.
- Maintenance and applicable taxes.
A suitable panel with reliable installation and clear warranty support may provide better long-term value than a cheaper option with limited documentation.
Solar Panel Manufacturers vs Solar System Manufacturers in India
The terms solar panel manufacturer and solar system manufacturer are often used interchangeably, but they describe different activities.
| Business types | Main role |
|---|---|
| Solar panel manufacturer | Produces photovoltaic modules |
| Solar cell manufacturer | Produces the cells used in modules |
| Solar system supplier | Supplies a combination of solar equipment |
| Solar EPC company | Designs, procures, installs, and commissions solar projects |
| Solar installer | Installs and connects solar equipment |
Some companies operate in more than one category.
Which company should you contact for rooftop solar?
If you want solar panels for your home, you generally need a qualified solar installer or EPC provider that can assess your roof, estimate system capacity, select compatible equipment, and manage installation and applicable approvals.
For a commercial or industrial project, compare technical specifications, project references, delivery capacity, installation capabilities, and after-sales support.
A module manufacturer may supply the panels without providing the complete installation service. Always clarify the scope of work before signing an agreement.
