This is the most popular passive solar technique. The most obvious example is orienting windows toward the sun, thereby allowing the sun’s radiation to enter the living space directly and heat ...

Windows with a northern exposure are a source of cool air ... efficient by creating a cooling effect during the hot summer months or by allowing the passive solar gain during cold winter months.

Array Technologies, a leading provider of solar tracker systems, worked with independent engineering and design firm DNV to study an alternative method to active stowing called passive stowing.
