The lightweight, low profile MCT module is a utility-scale collector packaged for roof deployment. The technology is designed to offset summertime peak loads by utilizing solar energy for commercial and industrial cooling needs. A demonstration system was recently installed and commissioned at SCU as part of the school’s solar-powered house, which won third place at the US Department of Energy’s 2007 Solar Decathlon.
The Chromasun MCT is a flat-panel solar thermal collector that can achieve a concentration of 25 times the sun using lightweight, highly reflective aluminium mirrors from Alanod-Solar. These mirrors pivot in unison to follow the sun. Solar energy is collected from the mirrors by a selectively coated stainless steel receiver type that can generate temperatures up to 200 °C. The entire system is enclosed with a sealed canopy to protect against the elements. It has no external moving parts and is mounted on the same racking systems as conventional flat-panel solar thermal collectors.
