The problem is that you have to go big or go home, the equipment cost doesn't stop at just throwing a few solar panels or a windmill on your roof. To "sell back" you first have to cancel out you own usage, the average household with a furnace, fridge and not much else will use more than an experimental setup will produce.

But you can save some money offsetting your usage. Be aware of some of the things most people don't think about though. First off, you need an automatic electrical isolation setup, which will automatically disconnect your main electrical service in the event of a power failure. This is to keep you from backfeeding the grid; if the power company has to work on a downed line, you don't want to be feeding power to a line that has been disconnected from the upstream side. This equipment has to be installed, inspected and approved and all components have to be CSA approved (ie no cheap Chinese eBay crap). This is a must; they can cut off your power and fine you if you are found in violation of code. So you have to account for the equipment and inspection fees that will wipe out most of the savings that can be made for the next 8 years.

Then you have to have the equipment to match the phase/frequency of your incoming line so you don't change line power factor.

And then lastly is the generation equipment.

And all this doesn't take into account maintenance and wear and tear; since the breakeven point right now is sitting at 20 years for a decent system, you have to hope that the equipment you buy will last that long trouble free.
