Deployment in the building integrated PV segment is accelerating, and so too are the number of solar products available to architects and developers. And while BIPV had long been the segment in which an array of thin-film technologies could shine, they are now in increasingly stiff competition with crystalline silicon rivals.
Heat pumps can now achieve sufficiently high flow temperatures to operate most heating systems, even in older buildings. They are not yet highly efficient, but new refrigerants are expected to provide a remedy. This presents a number of challenges, but German researchers and industry participants are working on solutions to harness the power of heat pumps to keep people warm throughout the year.
