The vast majority of solar heating systems require the installation of solar walls. Solar walls can be installed in new or existing buildings.

Solar walls require very little maintenance, do not contain any liquid or any floating component other than fans related to the venting system. Furthermore, solar walls function in cloudy conditions and throughout the night, even if they are a little less efficient. Their installation also qualifies for a multitude of financial aid options.
