Flexible new solar panel is almost 80% lighter than traditional panels

Comments Off on Flexible new solar panel is almost 80% lighter than traditional panels

Solar panels just got a lot slimmer. Zhengrong Shi, a.k.a. the Sun King, is now marketing eArche, a super flexible, ultrathin solar panel that could stretch along building facades, atop buses, or on top of carports to charge electric cars. According to Shi, the groundbreaking panel has unlimited potential, and 40 kilowatts (kW) of the new technology has already been installed in three locations throughout Australia . eArche draws on a composite material like that utilized in airplane windows that is almost 80 percent lighter than conventional photovoltaic panels, according to RenewEconomy. Shi is distributing his new products through Australian company Energus and Hong Kong company SunMan , and believes eArche is the biggest innovation in over 10 years in the solar industry . He told RenewEconomy, “Most of the cost reductions we have seen come from manufacturing, growing efficiency, and supply chain. There has been very little innovation on products and applications, so we have decided to focus on the panel itself, which has been very rigid and heavy.” Related: SolarWindow unveils new energy-generating glass that bends Some companies haven’t been able to install solar because panels are too heavy for their buildings’ roofs, but Shi’s technology could remove that issue. Rooftop solar systems typically weigh around eight metric tons for a 100 kW array, according to The Daily Advertiser, but eArche weighs just around two metric tons for 100 kW. Shi said eArche can be custom-shaped for building roofs or walls. He told RenewEconomy, “We think governments should require all new buildings to have solar panels integrated into their structure. With this panel, it is easy to do.” SunMan also envisions the technology on RVs, yachts, vending machines, and more. Time will tell if eArche is as revolutionary as Shi thinks. The technology stands in contrast to Tesla’s proposed solar tiles , which Shi said is “the wrong way of doing it” largely due to expense and weight.

Ultra-green house in Seattle marries aesthetics and sustainability

Comments Off on Ultra-green house in Seattle marries aesthetics and sustainability

This ultra-green house for a Seattle family of four has achieved an exceptional level of sustainability without compromising on aesthetics. Shed Architecture & Design designed the Madrona Passive House as a net-zero residence for former Microsoft program manager and renowned environmental advocate Jabe Blumenthal. With a super-insulated envelope and passive design features such as heat recovery systems, photovoltaics, green roofs and stormwater and rainwater harvesting, the house minimizes its energy consumption and act as a stellar example of climate-friendly living. The 3,700-square-foot home relies on solar panels , high-performance construction and a contemporary design for its energy efficiency. A well insulated envelope which includes a Zehnder ComfoAir heat recovery ventilator that pumps fresh air into the interior contributes to its low energy consumption . This technology also recovers 90 percent of thermal energy from exhaust air for reuse inside. Rainwater from the home’s roof and the green roof on the garage goes into two cisterns via permeable pavers, while mechanical shading system and triple-pane windows regulate solar gain . The owners can also tap into the building’s real-time consumption by using the circuit-by-circuit energy monitoring system with dashboard. Related: Seattle’s Palatine Passive House consumes 90% less energy than a conventional home Achieving the world’s most demanding building energy standards – Passive House – the building is expected to also receive the Department of Energy’s Zero Energy Ready and Living Building Challenge’s Net Zero Energy Building certifications. The project was recognized by Green Builder Media as winner of the 2016 Green Home of the Year Award in the Best Energy Efficiency category. + SHED Architecture & Design Via Green Builder Media Photos by Mark Woods
