Key Summary

India is witnessing a rapid rise in the adoption of solar energy, which can be attributed to the increasing cost of electricity, incentives from the government, and awareness of environmental protection. With the increasing capacity of renewable energy sources, the production of solar panels is increasing, with many solar panel manufacturers in India producing quality modules for both domestic and international use.

Selecting the right manufacturer is essential for the longevity, reliability, and return on investment for the solar panels. Among the many quality manufacturers, Alpex Solar is making a mark as a reliable manufacturer with efficient modules and increasing production capacity.

Real Project Highlights: 

GLH Public School, Haryana – 30 kW Rooftop Solar System: The GLH Public School in Haryana has installed a 30 kW rooftop solar system using Alpex Solar panels. The solar system was installed in order to save on electricity costs and encourage the concept of sustainable energy resources. The solar system will enable the school to generate electricity in an environmentally friendly way, saving them on their overall energy costs in the coming years.

Chandigarh College of Engineering and Technology (CCET), Chandigarh: A 365 kW solar system was installed at Chandigarh College of Engineering and Technology (Sector 26, Chandigarh) using Alpex Solar panels under an Exicom project. The solar system was installed in order to enable large-scale electricity generation for the institute.

Industrial Solar Project (Rajasthan): An industrial warehouse was provided with a large-scale solar system powered by Alpex Solar panels. The solar system was effective in providing a constant supply of electricity, allowing the company to move towards sustainable energy resources while saving on their overall electricity cost.

To better understand how the leading brands compare, the table below highlights the top solar panel companies in India based on manufacturing capacity, efficiency, warranty, and ideal application.

Note: Manufacturing capacities and efficiency figures are based on publicly available data and ALMM-listed capacities. Actual module performance may vary depending on the product model, installation conditions, and technological upgrades.

Different solar manufacturers specialize in different types of installations. While some brands focus on residential rooftop systems, others are better suited for large commercial or industrial solar projects. The table below highlights which solar panel companies are commonly preferred for each segment.

This comparison helps homeowners and businesses identify the best solar panel manufacturers in India based on project requirements, whether it’s a small rooftop system or a large commercial installation.

The solar sector in India is increasingly employing new technology to increase the efficiency and performance of the panel. The top manufacturers in the sector are focusing on advanced cell technology, high power modules, and smart energy solutions to meet the increased demand for solar energy.

The rapid growth of India’s solar manufacturing industry is significantly driven by government policies that aim to foster domestic manufacturing, reduce dependence on imports, and enhance technology uptake. Various programs implemented by the Ministry of New and Renewable Energy (MNRE) are helping domestic manufacturers increase their production levels and compete globally.

PLI Scheme (Production Linked Incentive)

The Production Linked Incentive (PLI) scheme for high-efficiency solar PV modules is perhaps one of the most impactful policies that are significantly driving India’s solar manufacturing industry. The scheme offers financial incentives to companies that establish domestic solar module manufacturing units through advanced technology. Under various phases of the scheme, several companies have been allotted capacity for integrated solar manufacturing units.

ALMM Priority List

The Approved List of Models and Manufacturers (ALMM) is another major regulatory framework that supports domestic solar manufacturers. Introduced by the MNRE, the ALMM ensures that only certified solar modules and manufacturers listed by the government are eligible for use in government-supported solar projects in India. This policy helps maintain quality standards, protects consumers, and promotes local manufacturing by encouraging the use of domestically produced solar panels.

Companies that are certified under ALMM are considered compliant with MNRE standards for solar panels, making them suitable for government-backed solar installations. Alpex Solar is already enlisted under ALMM, which not only adds credibility to its brand but also helps them participate in government solar projects and other government-backed renewable energy schemes.

Import Duties & Incentives

To support the development of the domestic solar industry, the government has also introduced Basic Customs Duty (BCD) on imported solar panels. Currently, imported solar panels and cells are subjected to high customs duty, i.e., around 40% on solar modules and 25% on solar cells, to dissuade dependence on imported panels and promote domestic manufacturers.

Overall, these policies play a crucial role in building a strong domestic solar manufacturing ecosystem and accelerating India’s transition toward renewable energy.

The selection of a suitable solar panel manufacturer is essential for the performance of the solar panel system. The key considerations for choosing a solar panel manufacturer include:
