The Bern University of Applied Sciences in Switzerland has published the initial results of a survey on the durability and performance of residential PV inverters and power optimisers over a 15-year period. They found that more than 65% of the inverters did not present yield-relevant faults by their 15th year of operation.

Malaysian researchers have developed a system that can absorb heat from PV modules and transmit it to a nanofluid, in order to transform it into thermal energy and use it for different applications. The panels have an overall efficiency of 89%.

Scientists in Sweden have compared AC and DC topologies in PV-powered buildings using battery storage. They have found that DC distribution systems can achieve energy savings when they are combined with solar-plus-storage systems.

An international research group claims that raw materials and land availability do not present a real barrier for a global energy system with solar at its centre. They said that forecasts for PV growth should not have their axis on utility-scale power plants and instead consider vertical PV, agrivoltaics, and floating PV as the source of future big market volumes.

Acen Renewables, a Manila-based developer, is building two solar plants in the provinces of Pangasinan and Zambales.

UK scientists have discovered that second-life batteries could provide a lower levelised cost of electricity (LCOE) than conventional batteries in school buildings equipped with PV in East African schools. They said the cheapest system configuration uses either 7.5 kW or 10 kW of solar with 20 kWh of storage.

PT PLN Nusantara Power has launched a tender for a floating PV project that will likely be built at a dam on the island of Java, Indonesia.

Scientists from Australia are among an international team of researchers that predict lightweight, high-performance perovskite solar modules could soon become competitive with crystalline PV modules in the residential segment, as such products will likely have lower manufacturing and balance-of-system costs in the future.

Researchers from Germany’s Fraunhofer FEP have unveiled a dirt-repellent coating for solar panels. The material is reportedly able to acquire superhydrophilic properties at night and wash away accumulated dirt with the aid of beads of moisture.

Scientists in Austria have developed a long-term energy storage system that uses regenerative braking to adjust the descent speed of sand in mine shafts and generate electricity.
