Detergent for solar module cleaning and protection

Developed and distributed by Portuguese start-up ChemiTek, the detergent is claimed to reduce water consumption by about 50% and increase energy production by up to 5%. The product was recently certified by the German laboratory TÜV Sud, according to the EN 61215 standard.

Hydrophobic anti-soiling coating for solar modules

A U.K. research group is developing an anti-soiling solution produced via a chemical process compatible with glass manufacturing. The Engineering and Physical Sciences Research Council is providing $1.6 million of funding for the project.

Solar module prices will stay high until 2023, IHS Markit says

IHS Markit predicts that global installed solar PV capacity will grow by 20% to over 200 GW in 2022, despite a difficult cost environment. PV system costs are expected to resume their downward trend from 2023, when more polysilicon capacities will come into operation.

European consortium develops ways to couple heat pumps with solar panels

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.

Reuse or replace? IEA PVPS analysis considers all options for underperfoming PV modules

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.

How PV performs close to radio, TV antennas

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

Insolight unveils 20.1%-efficient translucent photovoltaic panel for agrivoltaics

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.

Solliance hits 29.2% efficiency on perovskite/silicon tandem solar cell

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.

New tech to recover pure silicon from end-of-life solar cells

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%.

Sunman unveils 430 W glass free solar module

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.
