Manufacturing

Foreign direct investment’s role in bringing in finance, superior technology and other resources is undoubtedly a critical one. The Indian government has tried to create a conducive environment for enabling flow of foreign investments into the solar energy sector in the country, but the norms need to be eased further to really push the industry to its maximum growth potential.

An Indian research group has used three different chemicals instead of commonly used hydrofluoric acid to separate silicon from the cell. The technique is claimed to be able to deliver recycled silicon with a purity of up to 99.9984%.

The new product has a power conversion efficiency of up to 19.3% and a weight of 11.2 kg. The module is produced with glass fiber reinforced plastic, which the manufacturer says reduces light reflection and opens up new assembly options.

The input costs of the two biggest contributors to solar plant development expense have gone through the roof since the world began to come out of Covid-19 lockdowns, to leave project developers with some difficult choices.

Global bids are invited to set up giga-scale advanced-chemistry battery cell manufacturing units in India under the government’s production-linked incentive scheme. To be eligible for the government subsidy, the bidder would have to commit to setting up a minimum of 5 GWh capacity. Bidding is open until December 31.

The DC-coupled battery has 94.5% round-trip efficiency and the inverter offers up to 11.4 kW power and 10.3 kW backup power.

The four companies will each have half of their planned 4 GW annual production of polysilicon-to-module output subsidized by public funds.

Backsheet chalking, especially of polyamide backsheet films, doesn’t take long to lead to cracks and then safety shutdowns. Sometimes, though, the period may be much longer or shorter than expected. Assessing the risk and whether on-site repairs offer a long-term solution is currently a topic of strong debate within the PV industry, as Cornelia Lichner from the pv magazine Germany team reports.

India needs to install an average of 25 GW solar capacity every year to reach its renewable energy target of ‘450 GW by 2030’ with over 60% (280 GW) from solar. The nation must build enough manufacturing capacity back home to be ready on the supply side to support the new installations. 

Parity in the total cost of ownership already exists for electric two-wheelers and three-wheelers (with subsidy) vis-à-vis their internal combustion engine counterparts. Policy impetus, coupled with the production-linked incentive (PLI) scheme for batteries and auto components (exclusively covering EVs), is likely to further reduce costs and accelerate the transition to electric vehicles (EVs). The transition will also open up the market for new-age companies and innovators across the value chain.
