Founded in 2018, Edgehog Advanced Technologies has developed an omnidirectional anti-reflective glass for solar panels, which increases their production, especially at the start and end of the day.
Scientists in Spain have tested various properties of anti-reflective and anti-soiling coatings for PV module glass, aiming to develop a material that offers the best balance of desired material properties at the lowest cost. Over a year of testing, the best coatings were shown to boost module output by around 2%, and the group also made several observations that could influence future developments of coatings for PV module front glass.
Researchers in China have sought to understand how soiling exacerbated by anti-reflective coatings might inhibit solar panel output. In terms of effectiveness against soiling, the scientists found hollow-silica-nanoparticle coatings did better than solid silica alternatives.
The developer of the material, US-based specialist Pellucere, says its innovation can raise PV energy yield 3.5-4.2%.
