How does solar hot water work?

Flat plate collectors are installed (most commonly on a roof).  A pump circulates glycol (the heat-transfer fluid) through the collectors where it is warmed by the sun and then to a heat exchanger.  The heat exchanger heats the water that then flows into the home.

Does my house get enough sunlight to use solar hot water?

Solar water heating systems use both direct and diffuse solar radiation. Even if you don’t live in a climate that’s warm and sunny most of the time your site still might have an adequate solar resource. If your building site has unshaded areas and generally faces south, it’s a good candidate for a solar water heating system.  May Supply or your system installer can perform a solar site analysis to determine if solar will work for you.

Are there other things to consider before adding solar panels to my roof?

Before installing a solar water heating system, you should investigate local building codes, zoning ordinances, and subdivision covenants, as well as any special regulations pertaining to the site. You may need a building permit to install a solar energy system onto an existing building.  Your contractor will also ensure that the solar panels don’t exceed your roof load.
