Renac Power’s new hybrid inverters have efficiency ratings of up to 97.5% and European efficiency ratings of 97.2%. They are available in four versions, with power outputs ranging from 3 kW to 6 kW.

Esysunhome (ESYSH), a new energy storage company in China, has developed a 5.12 kWh lithium iron phosphate (LFP) battery system with a 7.9 kW inverter. It says six modules can be combined for up to 30.72 kWh of energy storage capacity.

The two dominant methods used in the industry to estimate soiling levels on solar projects go some way in mitigating losses, but there is plenty of scope for more accurate observation.

US scientists have discovered that using wavelength-selective, semi-transparent PV modules to absorb the blue light spectrum while transmitting red light onto crops can increase crop yield.

The future outlook for copper indium gallium selenide (CIGS) solar cells is bright, due to recent R&D achievements and efficiency gains, according to Ayodhya Tiwari, head of laboratory at Switzerland’s Federal Laboratories for Materials Science and Technology (EMPA). CIGS has already shown its value in building-integrated PV applications, but as production volumes increase in the years ahead, ground-mount plants and big utility-scale installations could also become feasible, says Tiwari.

Pusan National University researchers have found that hydrogen vaporization increases significantly as cryogenic tanks become emptier. The research sheds light on a key technology to transport hydrogen.

Alessandro Romeo, associate professor in experimental physics at Università degli studi di Verona, speaks to pv magazine about the advantages of cadmium-telluride (CdTe) solar cells over other thin-film PV technologies, as well as the commercial implications of future efficiency gains and the prospects for industrial expansion.

Chinese manufacturer Hoymiles has developed a new line of microinverters with up to 96.7% efficiency and outputs of up to 2,000 VA. It said they can be connected with up to four high-power solar modules.

The opening ceremony of Abu Dhabi Sustainability Week 2023 was not short of inspirational rhetoric, but the winners of the Zayed Sustainability Prize provided some real-world examples of what action on the local level really looks like.

A new report by the International Energy Agency’s Photovoltaic Power Systems Programme (IEA-PVPS) estimates that lost revenue from PV module soiling amounts to more than €3 billion ($3.2 billion) per year – an amount that is only set to increase as PV systems grow larger and more efficient.
