A one stop shop for the certification of solar PV panels
The IEC Conformity Assessment System for Electrotechnical Equipment and Components (IECEE) has been building trust for industries making and selling electronic equipment for the last 40 years, one the most important of them being the solar PV panel industry.
Titanium makes perovskite solar cells more durable
After finding a way to make spiro-OMeTAD, a popular perovskite solar cell hole transport layer, less prone to heat-induced crystallization, researchers at Georgia Institute of Technology are now seeking partners to scale the technology for large-area PV cells.
Vikram Solar to enter solid-state battery manufacturing
Indian PV manufacturer Vikram Solar says it plans to open a 1 GWh fully integrated solid-state cell and battery factory, expandable up to 5 GWh.
Gas quenching with helium, argon for more stable perovskite solar cells
Kuwait University researchers investigated the relationship between the molecular weight of the quenching gas and the morphology of perovskite films used in solar cells, finding that argon and helium extended device lifetimes compared to using the more conventional nitrogen.
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%.
