The Sun Horizon consortium has started to collect performance data on two pilot projects that combine heat pumps with solar systems using hybrid panels on homes in Riga, Latvia. The solution features a heat pump for space heating and domestic hot water and PVT panels to produce power for heating and domestic appliances, with excess power fed to the grid.

In a new report, experts from the International Energy Agency Photovoltaic Power System Programme (IEA-PVPS) have assessed the economical and environmental benefits of repairing and reusing or replacing solar modules that are not complying with a 30-year expected lifetime. They found that reusing offers the best environmental impact in all cases, while the profitability of this option is currently guaranteed only by rooftop PV under certain conditions. As for large-scale solar, module replacement remains the most competitive option.

Researchers in Kenya have analyzed the performance of an off-grid PV system located near an isotropic antenna as an emitting source.

Insolight has developed a translucent monocrystalline solar panel with a nominal power of 106 W and a power conversion efficiency of 20.1%. The solar cells are covered with protective glass and optical lenses to concentrate and direct sunlight onto them at around 100 times the intensity of standard solar glass.

The Solliance consortium has built a solar cell in a four-terminal tandem configuration that combines a 17.8%-efficient highly near-infrared transparent perovskite cell with a prototype of an 11.4%-efficient c-Si interdigitated back contact silicon heterojunction cell developed by Panasonic.

An Indian research group has used three different chemicals instead of commonly used hydrofluoric acid to separate silicon from the cell. The technique is claimed to be able to deliver recycled silicon with a purity of up to 99.9984%.

The new product has a power conversion efficiency of up to 19.3% and a weight of 11.2 kg. The module is produced with glass fiber reinforced plastic, which the manufacturer says reduces light reflection and opens up new assembly options.

Israel-based Augwind has built its first 250 kW/1 MWh compressed air storage system for the collective community of Yahel, in the southern, desert part of the country. The commercial scale facility will be connected to a PV system and will be used for behind-the-meter services.

Developed by French start-up EODev, the 100 kVa system is equipped with fuel cells manufactured by Toyota. The generator has a power of 110 kVA and its lifetime is guaranteed for 15,000 hours.

The 97%-efficient device is said to be the most powerful PV microinverter developed by the company to date and is capable of forming a microgrid during a power outage. The U.S. manufacturer expects to ship the first products in December.
