There are other factors to look at too folks. Since Canada isn't the sunniest country in the world, folks will have to buy a ton of PV panels to produce much solar electric. The cost to produce 1 KW of solar electric is going to be higher than the cost to produce 1 KW of wind electric.
I've heard that for every job you create, that money is turned over 7 times. How many jobs are going to be created making, shipping, and installing PV panels?
The 42 cents a KW does seem a bit strange, if they are only selling for 15 cents a KW, but it is possible to recoup their costs in the long run, by looking at total impact to the economy.
Good job Canada. Hopefully America will follow suit before it's too late. I live in Ohio, and our Governor recently offered incentives for wind electric...a 1.5 cent rebate on each KWH you produce with wind. Sounds great, but the fine print says that is only for 2.5 megawatt production or more.
