Innovative new coating for solar panels lets in more light

A unique antireflective coating has been developed by 3M and Ducatt to give solar panels a further sustainability edge. The coating works by enabling more light to reach the solar cells, increasing the electricity output of the panels by between three and five per cent.

Unlike existing antireflection coatings that use solvents that can harm the environment, the new coating is water-based so no air-polluting elements are released by the coating either during manufacturing or fitting.
