@AmeliasBrain @Daveography "Compared to the standard non-coloured solar panels scaling the rest of the building, the coloured panels that are part of the mural are 30 per cent less efficient depending on their hue, Mr. Tonsi says."But it will collect some power, looks cool, and prevents the building from being another grey eyesore in the downtown. The artwork is probably on the north side since it's not the biggest power generator anyway, and will keep the art from fading as fast.
