Longi said it has achieved a 26.56% efficiency rating for a gallium-doped, p-type heterojunction (HJT) solar cell and a 26.09% efficiency rating for an indium-free HJT cell, both based on M6 wafers. Germany’s Institute for Solar Energy Research in Hamelin (ISFH) has confirmed the results.

Masdar said it has started operating the 5 MW Ile de Romainville PV project in the Seychelles. The installation is backed by 3.3 MWh of storage capacity.

Robestec has connected a 220 MW/440 MW battery storage system to the grid in Ningxia, China. It is reportedly China’s largest standalone energy storage station, and uses lithium iron phosphate (LFP) batteries from Hithium Energy Storage.

A recently published report from the IEA-PVPS on building integrated photovoltaics (BIPV) digitalization found many BIPV professionals are unsure of a suitable method for estimating shading in BIPV projects.

The Flemish government will halve the solar panels premium from a maximum of €1,500 ($1,594) in 2022 to €750 from Jan. 1, 2023. It will also end the home battery premium earlier than initially announced, from April 2023. The premium for heat pump boilers, on the other hand, will be retroactively doubled.

Researchers from the United Kingdom, the United States and Australia have reportedly developed a perovskite solar cell with comparable stability and durability to commercial silicon PV cells. They used a high-temperature processing method with dimethylammonium chloride to control the intermediate phases of perovskite crystallization.

US-based Emporia Energy has developed a home battery system with an inverter and transformer. The lithium iron phosphate (LFP) battery has a storage capacity of 8.2 kWh, and up to six modules can be combined for up to 49 kWh of energy storage. The inverters come in 7.6 kW or 9.6 kW versions.

Chinese module manufacturer DAS Solar has launched an all-black bifacial glass-glass module series with an output of 410 W to 430 W. The new series features efficiencies of up to 22% and a temperature coefficient of -0.3% per degree Celsius. The company is offering a 15-year product warranty and a 30-year power warranty for 87.4% of the initial yield.

Growatt’s new APX HV cobalt-free lithium iron phosphate (LFP) battery has a storage capacity of 5 kWh and a nominal voltage of 650 V. It can be scaled up to six battery modules, for a maximum capacity of 30 kWh, or 60 kWh in parallel. It comes with a 10-year warranty.

Compagnie Ivoirienne d’Electricité (CIE), a utility in the Ivory Coast, is set to inaugurate its first solar plant – a €40 million ($42.6 million), 37.5 MW installation, backed by a 10 MW storage system by Saft.
