An owned system with SaskPower net metering documentation and a clean production history tends to be a selling point rather than an obstacle, since a buyer can see real utility savings on paper. Panel age and system size affect how strong that case is, but the asset itself is not the problem.
A leased system is the harder sale, because the buyer has to agree to assume the lease, buy it out, or have it removed before closing, a decision the lawyer closing the sale needs documented alongside the usual legal fees of $800 to $1,500, and some lenders are reluctant to finance a home with an active lease obligation attached.
