The launch of the new product suggests Tesla could renew its focus on residential solar and expand U.S. lease options with Powerwall.

UNSW researchers found that some POE encapsulants can trigger severe corrosion in TOPCon solar modules, causing up to 55% power loss under damp-heat conditions. Their study highlights that module reliability depends on the exact encapsulant formulation, not just the polymer type.

Axinar has launched SolBox, a direct PV water heating system that powers electric resistance accumulators without thermal collectors. It’s designed for homes and businesses, offering real-time monitoring, MPPT optimization, and automatic grid backup.

Abu Dhabi-based developer Masdar and Montenegro’s state-owned power company EPCG have entered into a framework agreement that could see a joint venture company belonging to the two parties develop, build, own and operate large-scale solar projects in the country.

Scientists have analyzed the competition between photovoltaics and agriculture for land use in Spain by studying 134 different crops in 15 regions. Using a real options framework, they found that falling solar PV costs and high irradiance in southern Spain could make solar more profitable than farming by the mid-2040s, highlighting growing land-use competition.

The Brazilian Association of Energy Storage Solutions (ABSAE) predicts that installations in Brazil’s commercial and industrial (C&I) segment should exceed 2 GWh in 2026. In addition, the group expects procurements of approximately 8 GWh in the auction scheduled for April, which will procure projects for delivery from 2028.

Rajasthan Solar Park Development Co. Ltd. (RSDCL) has issued a tender inviting bids to develop 2,450 MW of state transmission utility (STU)-connected solar PV capacity paired with 1,600 MW/6,400 MWh of battery energy storage systems at the Pugal Solar Park in Rajasthan’s Bikaner district. The projects will be implemented on a build-own-operate (BOO) basis.

Researchers from Australia’s national science agency are working with Malaysian authorities to assess how different battery chemistries perform under tropical conditions, including high temperatures, humidity, and corrosion, and how these factors affect durability, safety, and cost effectiveness.

Once considered isolated incidents, spontaneous glass breakages in solar modules are becoming more frequent, highlighting the limits of some manufacturing choices and the need for closer quality control.

The patent infringement case was related to an unspecified TOPCon solar cell technology.
