US startup develops air-source steam heat pump for industrial use
Colorado-based AtmosZero has closed a Series A funding round that will help it accelerate the commercialization of its Boiler 2.0 technology. The air-sourced heat pump generates steam for industrial use and can be combined with PV generation and storage.
Beny launches PV-ready EV charging station
Beny New Energy says its new charger can deliver power at a range of 360 kW—600 kW. It supports various connection standards.
Dynamic photovoltaic blinds for glaze-façade buildings
Scientists from China have built photovoltaic blinds that can reportedly regulate thermal load, daylight penetration, and energy generation in high-rise buildings with glazed facades. Their creators claim the blinds offer superior architectural aesthetics and notable energy-saving potential.
Austa releases new three-phase inverter series
The Chinese manufacturer said its new inverters can support up to 120% three-phase unbalanced output and provide 1.5 times DC overmatching.
PV-powered cars and the parking dilemma
Researchers in Portugal have addressed the so-called ‘parking dilemma’ of electric cars incorporating photovoltaic modules. They looked into the tradeoff between charging the car and raising its inside temperature. They calculated the critical time as a function of the car’s solar capacity.
Abandonded mine water source heat pump system for residential applications
Chinese researchers have designed an abandoned mine water source heat pump system that can reportedly perform better than gas boilers in residential buildings. It consists of a submersible pump, a plate heat exchanger, a water source heat pump, a circulating water pump, and an end section.
Online map for ground mounted solar plants in China
The China Agricultural University has created an online dataset presenting all PV plants deployed in China at the end of 2020. The tool shows China ground mounted solar facilities occupied a surface of 2,467.7 km2 at the end of December 2020.
New tech to remanufacture recycled perovskite solar cells
An international research team has developed a novel way to remanufacture fully encapsulated perovskite solar cells after recycling. The researchers say the devices can achieve 88% of the original efficiency of the products.
Metrel releases safety tester for 1,500 V PV installations
Metrel says its new safety-analysis tool can measure the insulation resistance of strings, the continuity of protective earth conductors, and I/U characteristics, among other features.
Scientists describe anti-soiling performance mechanisms in solar glass
Laboratory and outdoor soiling experiments conducted in Saudi Arabia have shown that increased particle resuspension by wind is one of the dominant factors for high anti-soiling performance in photovoltaic glass.
