Our objective is to demonstrate performance in -40C to +50C during 2017, although field testing to date (Sept 2016) has included a range of 0C to +38C. Components are typically rated for -40C to +80C operation. In terms of locations, the system can provide value in operations in remote places for most global locations/latitudes as far as the Arctic Circle. The flexible CIGS technology used in the RAPID ROLL is particularly good in low light and power production is possible from diffuse light or with low incident angle of sunlight in higher latitudes. The optimum performance typically occurs between the tropics and in some of these locations 365-day self-sufficient operation may be possible.
