The net-metering tradeoff

Common questions
Does Ontario have a solar rebate for Oakville homeowners?
There's no dedicated provincial solar cash rebate in Ontario right now. Net metering is the main financial tool, and it runs through Oakville Hydro rather than the province, so the credit rate and rules are set locally.
Is solar worth it in Oakville?
NRCan's solar resource data puts Oakville around 3.85 peak sun hours a day on an annual average, close to the strongest numbers recorded anywhere in southern Ontario. Payback usually lands in the 10 to 15 year range without a rebate, depending on system size, roof orientation, and your Oakville Hydro rate class.
Oakville Hydro stayed independent while its neighbours merged into Alectra
Mississauga, Markham, and Vaughan homeowners now deal with Alectra Utilities after a string of amalgamations across the GTA. Oakville never joined that consolidation. Oakville Hydro still runs its own interconnection process for anyone adding solar, which in practice means shorter chains of approval and a local contact who actually knows the town's grid rather than a call centre covering a dozen municipalities. Reach Oakville Hydro directly before you finalize a system size if you're planning to export any surplus power, since the net metering credit rate is theirs to set.
What Oakville's sun-hour number actually buys you
Oakville sits close to the top of Ontario's solar resource map, around 3.85 peak sun hours a day on NRCan's long-run averages. That's a real edge over cities further from the lake, but it's a small one in dollar terms. Roof pitch, shading from mature trees in older Oakville neighbourhoods, and how much of your own daytime usage the system offsets will move your payback number far more than the difference between 3.85 and 3.6 peak sun hours ever will.
Local groundwork before you sign anything
Oakville's Community Climate Action program and its Community Energy Strategy both flag rooftop solar as a lever for the town's emissions targets, and Oakville Hydro's own site has the current net metering application forms. Homeowners on forums like RedFlagDeals' solar thread bring up the same question over and over: whether to size a system for self-use or for export credits. For most Oakville homes without a rebate on the table, self-use tends to win out, since load displacement avoids retail rates directly rather than trading at the utility's credit rate.
