Scientists in India have combined a solar-assisted heat pump with a humidification-dehumidification and vapor compression refrigeration (HDH-VCR) cycle to generate heat and cooling. The system is reportedly able to generate up to 5.5 l per hour (LPH) of fresh water while achieving an ‘enhanced’ coefficient of performance.

A range of different factors can affect the productive lifespan of residential solar inverters.

A team of researchers from Norway analyzed a case study of a cascade hydropower system hybridized with both floating and ground mounted PV under sub-Saharan African market conditions. It found that hybrid systems can reduce seasonal variability in renewable energy generation and increase annual producer profits under both PPA and spot market schemes.

REC has developed a new series of heterojunction solar panels with efficiencies up to 22.6% and an operating temperature coefficient of -0.24% per degree Celsius.

With perovskite PV technology showing promise for next-generation solar manufacturers, LED steady-state solar simulators have the flexibility to provide perovskite developers with the measurement accuracy required.

Hoymiles has developed new hybrid inverters for residential PV applications. They have a nominal power range of 3.8 kW to 11.5 kW and an efficiency of 97.6%.

The i50 optimizer supports the largest utility-scale solar projects.

US researchers have developed a new high-voltage, membrane-free, nonaqueous lithium-based organic redox flow battery. They say that the elimination of the membrane decreases the upfront costs of the battery by as much as 30%.

The cell has an area of 333.4 cm2 and is based on passivating contacts based on polysilicon and silicon monoxide (SiOx). The Fujian Metrology Institute in China has confirmed the result.

Scientists in the US developed a series of accelerated testing procedures designed to predict how perovskite solar cells will perform when installed outdoors for a long period of time. The study finds that combined, simultaneous exposure to light and heat gives the most accurate of how a perovskite solar cell will perform in the field.
