Sungrow debuts 2.5 kW microinverter
The Chinese company said its new microinverter supports four independent MPPT inputs with DC input currents up to 18 A.
All-perovskite PV-powered battery for portable electronics
Scientists have used a dual-functional, material-sharing strategy with ethyl viologen diiodide to achieve synergistic performance enhancement in PV-powered batteries. The system was reportedly able to power a wearable glucose monitor for 24 hours.
Euronergy launches new lightweight PV module series
The Dutch company said the new products have a power output ranging from 410 W to 430 W in power and an efficiency of up to 22.2%. The panels reportedly weigh 30% less than conventional counterparts.
Using drones, satellite and ground data to map vegetation in PV plants
Scientists have developed a multi-scale method to assess vegetation conditions inside PV power plants. The research focused on nine PV plants in China across diverse climate zones. Compared to satellite estimates alone, the method reduces bias by 16.98%.
Researchers use guanidinium thiocyanate to raise perovskite cell efficiency
Researchers have used guanidinium thiocyanate as a chaotropic agent to modulate the crystal growth rate during perovskite crystallization. They compared different concentrations of the guanidinium thiocyanate. Champion device efficiency was 22.34%.
Novel MPPT technique for EV charging combined with PV, fuel cells
Scientists in India have designed a system that uses PV panels, a proton-exchange membrane fuel cell, battery storage, and a supercapacitor. It also relies on an adaptive neuro-fuzzy inference system-based MPPT that reportedly achieves an efficiency of 98.7%.
SAJ launches HS3 6-in-one home battery with 40 kWh storage
China’s SAJ has launched its HS3 6-in-one home battery series, available in single- and three-phase configurations with 1,000 W to 15,000 W of PV input and up to 40 kWh of lithium iron phosphate (LiFePO4) storage.
Reducing PV module temperature with ultra-cooling patch
Scientists in Hong Kong have developed a patch that effectively cools down PV panels and utilizes waste heat for freshwater production. It has three layers: an atmospheric water harvester, a thermal regulation layer, and an adhesive layer. Maximum power density reportedly increased by over 28% in a folded version of the ultra-cooling patch.
Germany offers best European policy for agrivoltaics, claim researchers
Scientists in Canada studied romaine lettuce growth under cadmium telluride thin-film solar modules with varying transparency and photosynthetically active radiation, and found Germany’s regulatory framework most effective for maximizing agrivoltaic benefits.
Photovoltaics for mango drying
Scientists have created a solar cabinet dryer for mango slices, with PV-powered forced convection. Placing mango slices of different thicknesses inside, they have measured the operation of their device against two reference methods and have found that thermal efficiency reached 30%.
