EU raises concerns about production requirements in U.S. Inflation Reduction Act
The European Union and the United States are seeking a solution for key aspects of “discriminatory” production requirements in the US Inflation Reduction Act (IRA). The EU said it might bring the case to the World Trade Organization if a compromise cannot be reached.
Underground heat exchanger to cool down solar panels
Spanish scientists have built a cooling system featuring heat exchangers on solar panels and U-shape heat exchangers installed in a borehole at a depth of 15 meters. The researchers claim that this reduces panel temperatures by up to 17%, while improving performance by about 11%.
China’s solar cell production capacity may reach 600 GW by year-end
The Asia Europe Clean Energy (Solar) Advisory revealed that most of the planned new solar cell production capacity relates to high-efficiency n-type cell technologies such as TOPCon and HJT.
Quinone flow battery for grid-scale renewables storage now close to commercial viability
Startup Quino Energy has raised more than $7.8 million to scale up its quinone redox flow battery technology. Harvard University and University of Cambridge researchers came up with the initial research for the battery design.
TOPCon solar cell achieves 24.2% efficiency via new plasma-assisted atomic layer deposition tech
A team of international researchers has simplified the deposition of thin film layers in the commercial production of TOPCon solar cells. Via a tube-type industrial plasma-assisted atomic layer deposition (PEALD) technique, they were able to achieve a power conversion efficiency of 22.8% in a 60-cell, 613 W TOPCon module.
DC rooftop PV providing domestic hot water to residential building at 140 F
Domestic hot water, with a heating system powered exclusively by DC solar power, has now covered the needs of an apartment building in Linz, Austria, for a period of a year. The 14 residential units are each connected to their own 1.36 KW solar arrays.
Solliance hits 30.1% efficiency on perovskite/silicon tandem solar cell
The Solliance consortium achieved a 29.2% record efficiency for the solar cell in November 2021, from just 28.7% in March 2020. In recent months, it increased the perovskite cell for the tandem device from 17.8% to 19.7%.
Sunpower launches two new batteries for residential applications
The two batteries have a storage capacity of 13 and 19.5 kWh, respectively. Both lithium-ion systems use LiFePO4 as the cathode material and have a round-trip efficiency of over 86%.
U.S. startup unveils 5 kW solar canopy for EV charging
Paired Power said its new 5 kW solar canopy measures 10.5 feet by 16.4 feet by 12.13 feet and can host up to 10 bifacial solar panels. It can be used in on-grid or off-grid modes and can be paired with lithium-ion battery storage systems up to 40 kWh in size.
Panasonic presents 22.2% efficient all-black heterojunction solar module compatible with its EverVolt battery
The new module series has a power output ranging from 420 to 430 W, a temperature coefficient of -0.26% per degree Celsius, and an efficiency of up to 22.2%.
