US lab reveals top findings for hybrid solar, storage plants
US government researchers have collected 10 observations from recent research papers that look at solar- or wind-plus-storage power plants in the United States.
PV-powered portable seawater desalination system for drinking water
US researchers have developed a portable desalination unit that generates clean drinking water without filters or high-pressure pumps. The device is powered exclusively by solar energy and requires just 20 W of power per liter.
The Hydrogen Stream: Acid-treated cells produce about 200% more hydrogen
US scientists have improved the performance of intermediate-temperature electrolyzers based on protonic ceramic electrochemical cells. Germany and India have signed a hydrogen cooperation deal, while ArcelorMittal has tested the use of green hydrogen in the production of direct reduced iron at a steel plant in Canada.
Renac Power unveils high-voltage residential battery
Renac Power’s new plug-and-play battery has a storage capacity of 3.74 kWh, but it can be enhanced in series with up to five batteries to 18.7 kWh. It has a nominal voltage of 96 V and a voltage range of 81 V to 108 V.
Sharp launches 540 W bifacial solar module
Sharp’s new IEC 61215 and IEC 61730-certified-certified panel features 144 half-cells based on M10 wafers and a 10-busbar design. Its operating temperature coefficient is -0.349% per degree Celsius and its power tolerance reaches up to 5%.
Titanium oxide nanoparticle-based perovskite PV cell with 24.05% efficiency
A new perovskite PV cell based on titanium dioxide nanoparticles exhibits low efficiency losses when scaled up from cell to module.
Solar briefcase packs in 200 W for off-grid, mobile living
FlexSolar has developed a foldable, portable PV briefcase kit with a charge controller and connection cables.
Novel PV system design for green rooftops from France
French startup Ecovégétal has developed a PV system configuration that uses vegetation to reduce the operating temperature of the modules. It says the presence of certain plants on a flat rooftop can even serve as a bulwark against the risk of fire.
Self-powered, dry-cleaning robot for solar panels
Enray Solutions has developed an autonomous, water-free cleaning robot for ground-mount solar installations that draws its power from an on-board PV panel and battery. The robot is designed to withstand the harsh environmental conditions of all kinds of terrain.
US startup claims hydrogen output for $0.85/kg or less via new water vapor electrolyzer
Advanced Ionics has developed an electrolyzer that runs at temperatures below 650 C. It is reportedly able to produce hydrogen for $0.85/kg or less. CEO Chad Mason recently spoke with pv magazine to provide a closer look at the water vapor electrolysis tech.
