1Komma5° releases residential battery for non-PV homeowners
1Komma5° has launched PowerHarvester, a lithium iron phosphate battery system for residential customers without solar. It is offering six power classes and storage capacities from 7.7 kWh to 27.2 kWh.
Bulgarian tender awards nearly 10 GWh of energy storage
Bulgaria’s standalone energy storage tender, which aimed to procure at least 3 GWh of cumulative usable capacity, ultimately awarded more than three times that amount.
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.
