Waaree Energies Launches Bifacial PV Module For India Rooftop Market

One of India’s largest solar module manufacturers has launched two new products focused on the country’s rooftop solar power market. The company now expects an exponential growth trajectory over the next few years.

Waaree Energies has announced the launch of two new solar power modules which it projects are the ‘future of the rooftop market’. The first product is the 400 Wp capacity doublet module. The module is actually two modules combined into one.

The Super 400 module consists of two modules of half cut cells interconnected in parallel to each other. While there is little difference in installation and arrangement of modules, these doublet modules offer some significant advantages that can make a substantial difference in the performance of rooftop solar power systems. An article at Saur Energy explains these advantages.

The Super 400 module uses half-cut cells which result in reduction in resistive losses. With the fall in resistance losses the module temperature also reduces resulting in improved operational efficiency. The doublet module has more open area compared to traditional modules which allows more radiation to be reflected from the backsheet. Also, excited electrons are required to travel half the distance to reach the junction box compared to traditional modules.

As the new module is essentially two traditional modules interconnected in parallel, any loss in generation due to shade is reduced by half compared to traditional modules. In traditional modules a shadow on a one half of the module results in complete loss in generation. However, in a doublet module, shadow over one-half of the module reduces the generation only by 50%. 

The bifacial and doublet features of the new Super 400 modules launched by Waaree addresses some of the most important issues related to rooftop solar power systems. Cities, where most rooftop solar power systems are installed, usually do not have very high solar radiation. Additionally, high-rise buildings create the problem of shadow loss in solar modules.

Waaree believes that with these two new products it would be able to address these concerns and grab a large market share in the rooftop market. Waaree, like other Indian module manufacturers, face huge hurdles penetrating the utility-scale solar power market due to much cheaper Chinese modules. The Indian government has set an overly ambitious rooftop target of 40 gigawatts by March 2022. Waaree sees this as a huge opportunity to offset the lost opportunity in the utility-scale market.
