Technology Trends Among Top Solar Panel Companies

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.

  • Mono PERC Modules: Modules that use this technology are highly efficient and perform well in low-light conditions.
  • TOPCon Technology: The latest technology in solar cells that offers high efficiency and low degradation compared to other modules.
  • Bifacial Solar Panels: Solar panels that can generate power from both sides of the panel, increasing the overall energy output from the panel.
  • High Wattage Modules: Manufacturers are producing high-wattage modules greater than 600 Wp, helping to reduce installation costs and increase energy generation.
  • Smart Solar & Storage: The latest technology in solar solutions that offers monitoring capabilities and battery integration for better performance.

Government Support: Solar Policies Driving Indian Manufacturing

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.

How to Choose the Right Solar Panel Manufacturer

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:

  • Efficiency of the Solar Panel: It is essential to select a solar panel that has high efficiency since the area available on the roof is limited.

  •  Manufacturer Warranty: A manufacturer that provides a warranty for 25 years or longer is always a better option.

  • After-Sales Support: It is essential to select a manufacturer that provides good after-sales support.
  • Technology Used by Manufacturer: Modern technology like Mono PERC and TOPCon used by Alpex Solar provides high efficiency and better performance.

  • Approvals by BIS, IEC, ALMM: The solar panel must be approved by these bodies for better performance.
  • Performance in Indian Weather Conditions: The solar panel must perform well in Indian weather conditions.
