    c) All piping connecting the solar storage tank to the conventional water heater.
  6. Applicant must own the house where the system is installed.

Efficiency Nova Scotia recommends that those planning to install a solar system obtain three quotes before deciding on a system and contractor. To learn about the different types of panels you can use, click here. Eligible panels must be listed under one of the following:

- CSA 378 List of Accepted Collectors (click here for list)

- CSA 379 List of Accepted Systems (click here for list) 

- CSA List of Solar Concentrators (click here for list) 

- Or the former F378 list, previously administered by Natural Resources Canada

Please note that all electrical components that are used with the overall system must be properly approved for use in Nova Scotia (ie. a CE or CCC marking is not acceptable - approval must be equivalent to CSA).

Efficiency Nova Scotia also offers solar air heating and water heating rebates for commercial systems. For more information, click here.
