A UK company developing spray-on solar panels says its technology could be up to 10 times cheaper to produce than traditional photovoltaic cells.

There’s no doubt solar energy is a compelling alternative to fossil fuels, but implementing it has traditionally meant installing the standard, costly and ungainly solar panel. SRS Energy’s dual-purpose roof tiles offer one way to get around that requirement; now another comes in the form of thin, flexible solar sheets that can be integrated with architectural building materials.
