Ottawa, Ontario, Canada truly is a solar city. As a sometimes solar
contractor I know this from all the systems I've installed but I also
see a growing number of systems I'm not familiar with, and I discover
new ones all the time. Below are a sample.
Solar power/photovoltaic systems in Ottawa
Buying power from the grid/power utility is far cheaper than
installing a solar system and going off-grid... unless you take advantage
of Ontario's microFIT
program. This allows you to generate your own electricity using solar
and sell it to the grid at a much higher price than you pay when buying
electricity from the grid. So in the city, almost all solar power systems are
doing this. To learn more, see the
solar power section.
Passive solar house including green roof, abundant south
facing windows for heating in winter and overhangs to shade them
in summer, superb insulation, a geothermal system for heating and
cooling, high performance doors and very energy efficient windows.
On the right is solar power and on the left is solar hot
water heating. I don't know if they're selling power to the grid.
With such a small system they may have some batteries and use the
power themselves for a few appliances.

Solar thermal/solar hot water systems in Ottawa
Solar thermal involves using the sun to heat water, usually for tap
water, shower, dish and clothes washing, but sometimes for space
heating too. To learn more, see the
solar hot water section.
Small system good for 2 or 3 people.
Large one for a group of people.
This set of 48 townhouses each has 2 solar collectors heating
water for them, giving a total of 96 collectors (Heliodyne GOBI 406
Solar pool heating systems in Ottawa
Using solar to heat pools extends the swimming season by a month
or two on either end. To learn more, see the
solar pool heating section.
Solar air heating systems in Ottawa
With solar air heating, indoor air is circulated through a
box, usually mounted on a wall, which allows the sun to heat it
before flowing back indoors. To learn more, see the
solar air heating section.
