Photovoltaic panels and solar hot water panels both provide useful benefits for the buildings they are attached to, but sometimes there is limited space on the roof, and usually only one or the other is installed. Solimpeks, a solar panel manufacturer based in Turkey, has been producing solar panels for a long time, and has an elegant solution to the problem: a panel that produces both electricity and hot water. It turns out that the Solimpeks Volther dual-use panels increase efficiency more than you might expect.
New Jersey-based Englert, a company that specializes in metal roofing and gutter systems, recently earned a citation from Architect Magazine for their incredible Solar Sandwich roof system. On the surface, it looks like any other standing-seam metal roof with columns of thin-film photovoltaic solar. Yet below that, to capture the warmth generated from hot metal roofing, there’s a grid of pex-filled purlins with a water and glycol solution for a solar thermal system.
EnergyHub just announced the launch of an energy management system for consumers interested in monitoring, controlling, and reducing energy use.
