On their website, they have the following quote:

Since the launch of the GENERATE CHOICE program, ENMAX has installed more than 500 kilowatts of micro-generation. In 2012, the average 6 module solar PV system ENMAX installed produced 1593kWh per system for the year.

Assuming someone is paying Enmax 8.9 cents per kWh, which is their current contract price, the average system would save you $141.78 per year, for low monthly payments totalling only $719.88 per year.
But those are averages. Maybe you're Joe-Kickass and it's always sunny at your house, the pitch of your roof is exactly our latitutde, and your house rotates to face the sun. Once Enmax installs your new 1.3 kW system, you're going to be generating at 100% of rated capacity all year round. In that case 1.3 kW * 365 days * 14 hours per day of sunshine (it's always summer at your house) = 6643 kWh, for a total value of $591.23 per year. There's no way this pays out.
If you're looking for a warm fuzzy, it probably makes sense to just sign up with Bullfrog and get the sign.
Edited to add: It would actually pay out at 24 hours/day and 100% capacity. So if you can figure out a way to eliminate night, winter, snow and clouds this might work for you.
