Rhoss launches reversible heat pumps
Conceived for industrial applications, the novel heat pumps can reportedly deliver hot water at 65 C from -10 C up to 35 C of external air, and hot water at 55 C down to -20 C of external air. Their coefficient of performance reaches up to 3.60.
Low-cost conductive quantum dot inks for photovoltaics
An international research team has developed a method to economically synthesize and stabilize conductive colloidal quantum dot inks for solar applications. When used to make quantum dot films in large area PV devices they enabled a certified efficiency of 10%, with lab-sized cells based on the ink material achieving 13.40% efficiency.
TBEA unveils 400 kW string PCS, 6.25 MWh battery
The Chinese manufacturer has designed a new high-density 400 kW power conversion system (PCS) and 6.25 MWh battery energy storage system (BESS) to cut costs and boost deployment speed.
Gautam Solar presents 23.69%-efficient 640 W TOPCon solar module
The Indian manufacturer said its new TOPCon solar panel is based on rectangular bifacial solar cells and is certified by the Bureau of Indian Standards (BIS).
EVA-induced degradation has significant impact on power losses in TOPCon solar modules
New research from UNSW shows that EVA-encapsulated TOPCon solar modules under damp-heat testing can suffer significant power losses and fill factor drops. The study describes metallization degradation mechanisms driven by EVA-generated contaminants and demonstrates the effectiveness of metallization adjustments in reducing EVA-induced degradation rates
Engie trial turns Australian solar curtailment into revenue stream
Engie and SA Power Networks have doubled participation in a rooftop solar curtailment trial to 100 households after hitting the initial cap of 50, offering financial rewards to help manage periodic oversupply.
WorldOne Energies commissions 1.2 GW solar module line
WorldOne Energies has commissioned a 1.2 GW solar module manufacturing line that will produce its Supreme series n-type tunnel oxide passivated contact (TOPCon) panels.
New tool aims to cut costly hail losses in utility-scale solar
Hail damage accounts for just 2% of filed solar insurance claims but more than 50% of total costs, according to VDE Americas.
U.S. Commerce Department slaps unexpectedly high tariffs on solar imports
Coalition trade lawyer says the U.S. Department of Commerce’s final tariffs on solar cells and modules from Cambodia, Malaysia, Thailand and Vietnam are among the highest rates he’s ever seen.
Net metering policies see significant revision in states across the U.S.
The recent 50 States of Solar report from NC Clean Energy Technology Center identifies three trends in state policy activities and the top five distributed solar actions in Q1 2025.
