I'm looking to have a ~20kW grid-tied solar system installed at our property in Ontario, Canada. I've been searching and reading but am unable to find current (last year or two) data on how much such a system should cost (per watt installed).
There's no shortage or news and press releases regarding falling prices of PV and batteries over the years but locating information of the form "it cost this to install it" seems more illusive.
I've been quoted $5(CAD)/kW installed (no batteries). How does one go about finding out a reasonable rate for installed solar?
