What kind of backup system should I use with my solar installation?

What kind of backup system for my solar installation? This is a common question.

DualSun has no particular recommendation for the choice of backup system; it all depends on the type/source of energy that you favor according to your budget, the technical specificities of your equipment, and your ecological awareness. Some examples according to the energy source of your backup system are:

  • fuel oil: fossil fuel, CO2 emitter, inexpensive
  • wood: source more ecological than fossil fuel, local, inexpensive per kWh, but a bit more expensive at the point of sale
  • electric: low CO2 emissions, flexible and easy to install, expensive per kWh for heating
  • gas: fossil fuel, not local, appropriate if connected to a gas network, inexpensive
