There is a couple of items not in this and with Sask power-well the rebates for the solar panels that will be covered with snow half the year-speaks for itself.If yer on battery bank-most areas of Sask have both good wind and sun.A mainly PV based systen that includes a small turbine-can take considerable strain off the depth of discharge on the cells.As batteries are the mill stone round the neck of such systems-the potential too double the battery bank life with proper maintence,multiplies operating savings.
As well actual(thermal) measurements over 30 years ago, showed that the optimium angle for fixed mount solar is 90* at sites above45* latitude.My documents are destroyed-but even when I could show them,everyone knew that the panels had too be sloped on a roof-mounting them on a south wall was heresy.The resultant losses due too stupidity also multiply.
