Photovoltaics for refrigerated warehouses
Scientists in China have analyzed the performance of PV-driven refrigeration warehouses and have found they can ensure stable operation thanks to a refrigeration coefficient of performance of up to 2.66.
Aerocompact releases new portrait mounting system
Austrian manufacturer Aerocompact has developed the SN2 Q PLUS solar mounting system, which can support PV modules measuring up to 1,310 mm x 2,500 mm. It has an installation angle of between 5 degrees and 10 degrees.
Improving silicon solar cell performance with aluminum-doped polysilicon passivating contacts
An international research group has developed a novel technique enabling the creation of contacts at low temperatures. The novel contact types are reportedly able to enhance cell efficiency by up to 3%.
New design for photovoltaic-thermal panels mitigates risk of cracking
Researchers in Sweden have developed a new PVT module using an aluminum alloy structure between the thermal absorber and the photovoltac cells. This architecture reportedly reduces thermal expansion by 20%, thus increasing the chances of mitigating cracks in the PV unit.
Trina Solar unit releases new version of Vanguard 1P solar tracker
TrinaTracker, a division of China’s Trina Solar, says its new Vanguard 1P tracker system has a maximum length of 140 meters and can be equipped with N-type modules.
Performance assessment of air-source heat pumps in office buildings
Scientists have analyzed the performances of two air-source heat pumps in two small office buildings in China during the heating season. They identified the instantaneous load of the building as a critical cause of low energy efficiency.
Enhancing PV performance with graphite-based thermoelectric generator
Indian scientists have built a PV system coupled with a thermoelectric generator using graphite as a heat dissipator. The graphite-based system achieved a higher output and temperature gradient than a reference system without heat dissipation.
Socomec releases new modular energy storage system
Socomec says its new modular energy storage system includes a converter and up to six battery cabinets. At maximum capacity, it can store 1,116 kWh.
GoodWe releases 60 kWh battery for commercial, industrial PV systems
GoodWe has developed a 60 kWh battery for commercial and industrial PV systems, featuring a compartment for its ET15-30kW inverter series.
UK researchers identify optimal heat pump design minimizing system transition costs
Researchers led by the Imperial College London have analyzed the effects different kinds of air-to-water heat pumps will have on the UK energy system, based on their coefficient of performance and price. They also identified a point of diminishing returns, after which it is more cost-effective to invest in centralized energy generation and storage.
