Vaillant, Fraunhofer ISE present residential heat pump with new safety concept
The novel heat pump system relies on a thermal sensor based on an adsorbent-coated sensor layout developed by Vaillant in cooperation with the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE). This technology is reportedly effective in preventing propane from forming an ignitable mixture with air outside the device.
Triple Solar unveils PVT-assisted heat pump using waste heat from PV
Triple Solar BV has developed a residential photovoltaic-thermal (PVT) heat pump that uses waste heat from PV modules, eliminating the need for an outdoor unit.
At high latitudes, vertical PV is more profitable in February than horizontal panels in June
A 248 kWp solar system deployed on the roof of Oslo’s Ullevaal Stadium was found to be more profitable in February than a comparative horizontal array in June. The vertical panels’ ability to generate more energy in winter months than horizontal equivalents helped save more money against Norway’s typically high electricity prices in winter.
Withthegrid expands real-time renewable energy asset controlling platform
