Daikin unveils air-to-water heat pump for commercial buildings
The new heat pump series uses propane as the refrigerant and can reportedly provide hot water up to 75 C.
Fortress Power introduces 9.6 kWh stackable home battery
The battery stacks up to three units for 28.8 kWh and is rated for 8000 cycles at a 70% depth-of-discharge.
Energy storage system powered by forest waste retains 60% capacity after 10,000 cycles
Researchers in Spain used electrodes derived from wood biomass discarded by sawmills as waste to create a hybrid system combining batteries and supercapacitors.
UtmoLight pushes perovksite PV module efficiency to 18.1%
UtmoLight has reached 18.1% efficiency with its perovskite PV modules, according to results confirmed by the US National Renewable Energy Laboratory (NREL).
US solar facilities lost $5,720 per MW to equipment issues in 2024
US solar facilities lost $5,720 per megawatt in 2024, with global losses from equipment failures and extreme weather reaching $10 billion. Raptor Maps says 193 GW of projects recorded rising power losses, primarily from inverters, strings, and combiners, with regional weather risks varying significantly.
The effect of PV modules on green roofs
Scientists have used simplified 2D view factor and advanced 3D approach to calculate energy fluxes on green roofs with PV systems. They have also constructed an experimental setup to verify their model and have found that without the detailed model, evapotranspiration would be underestimated by 18%.
Trina, Daidohant launch new load-bearing mounting solution for heavy snowfall
The Chinese manufacturer has collaborated with Japan’s Daidohant on the new product. It reportedly suppresses deformation with a special bar attached to the back of the solar module.
Tandem PV moves toward perovskite manufacturing with $50 million funding
With a perovskite layer 200 times thinner than silicon and requiring just 10% of the energy needed to produce conventional panels, Tandem PV reports it will be able to reduce energy use during manufacturing.
Sungrow unveils 5 kWh home battery system
Sungrow’s new residential battery energy storage system features a compact 182 mm design and is capable of handling a maximum charge/discharge current of 50 A.
Coupling solar-air source heat pumps with sand-based thermal storage floor
Scientists in China have analyzed the performance of a system linking a solar-air source heat pump heating system to sand-based thermal storage floor and have found it can maitain an average indoor temperature of 18.8 C, even when outdoor temperatures range from −18.4 C to 12.3 C.
