The Danish Energy Agency will launch a 500 m ( $ 1.3 m ) , three - year pilot to determine the effectiveness of adding solar modules directly to rooftop solar layers . The PV Rock Roof initiative , running from October 2019 to October 2020 , will use weather - proof panels manufactured by Dansk Solenergi and will assess the use of translucent coloured layers , as well as various approaches to the cost - effective thermal insulation of large roof areas . The PV industry is also exploring covering whole panels in solar skins to reduce electricity demand on the grid .
