Q: What kind of solar system is right for me, solar thermal or solar electric? Which is better?
A: A simple solar thermal system is most appropriate for typical residential household energy consumption.

There are two kinds of solar collectors:

  1. solar thermal collectors, that make heat, usually in the form of a warm liquid, and
  2. photovoltaic collectors, that make electricity.
Unfortunately photovoltaic collectors are much more expensive than thermal collectors, and they are considerably less efficient. It is almost never a good idea to make electricity with photovoltaic collectors and then use the electricity to make heat.

If you find yourself using electricity to make heat or hot water, it would have been far more cost effective and energy effiicent to have used a solar thermal collector in the first place.

Solar photovoltaic electric systems  are not a good way to make a lot of heat, and they will not be in the foreseeable future. It is our opinion that electricity is a premium energy source, and its use should be reserved for end uses that require its unique qualities and properties, and where its expense can be justified. 

Radiantec  is a solar thermal company. 

Most of the energy that a typical residential household consumes is used for simple thermal tasks such as space heating, the production of domestic hot water and cooling. A simple solar thermal system is most appropriate for these needs.

We suggest that you consult with Solar Works Company for your photovoltaic needs.
