New bifacial agrivoltaic solar panels from Greece

Brite Solar, a Greek specialty module manufacturer targeting the agrivoltaics greenhouse and PV canopy segments, is building a 150 MW production line. Marketing its modules to farming cooperatives, integrators and installers since the end of 2022, Brite solar has pilot installations in North America, Southeast Asia, and Europe. In January it announced raising $9.26 million in venture capital.

Coating metallic ribbons for aesthetic implementation of BIPV

Researchers in Switzerland have looked into three kinds of black ink coating for metallic ribbons used in PV modules. They have compared their visual stability and their effect on electrical performance.

Titanium oxide hydrophobic coating to clean solar panels

Germany’s Fraunhofer FEP has unveiled a dirt-repellent coating for solar panels. The material is reportedly able to acquire superhydrophilic properties at night and wash away the dirt through the beading raindrops.

Hydrophobic nanocoating to reduce soiling in solar panels

Scientists in Egypt have created a self-cleaning, hydrophobic coating for solar panels that reportedly increases their efficiency by more than 30%. They used a coating solution based on polydimethylsiloxane (PDMS) and silicon dioxide (SiO2) nanocomposites, mixed with ethanol and isopropanol.

Promising soiling mitigation solutions should not be left to gather dust

A study has estimated the cost of PV project soiling may increase from €3-5 billion last year to €4-7 billion by 2023 due to more extensive deployment in high insolation and soiling-affected regions, such as China and India. The authors of the paper outlined the potential of soiling mitigation technologies while stressing more R&D is needed to reduce costs and for the adoption of such measures on a larger scale.
