FAQ(1). Are the solar collectors noticeable on the roof?
If only the collector is mounted on the roof it should blend into the roof design quite well. Our solar collectors are very thin and can be flush mounted on a roof. From a distance they look somewhat like a skylight. You may have to check with your local council regarding building restrictions when installing your solar collector.

(2). Can the solar collectors be mounted on a flat surface?
Yes they may be mounted on a flat roof or on the ground by using a stainless steel Flat Roof Frame. The collector should be installed at a minimum of 20o angle to ensure optimal heat pipe operation.

(3). How do I protect my solar system during subzero temperatures?
If you have a system that is operating in areas with subzero temperatures, freeze protection must be implemented. The easiest means of preventing freezing is to use a controller with a low temperatures setting, so when the manifold temperature drops below a certain pre-set temperature (5oC/40oF), the pump will circulate, warming the collector with water from the bottom of the storage tank. The pump will not run continually, just periodically, the frequency of which will depend on the outside temperature. In extremely cold areas, a closed loop using a glycol/water mix may be appropriate.
