As mentioned in a previous post, last summer we had solar panels installed on the roof of our
central Ottawa home. At the end of
August, we became small-scale energy producers, selling power back to the grid under
Ontario’s Microfit program. Our photovoltaic system (solar
electric) consists of 20 panels (called an array), and a grid-tie inverter,
which converts the panels DC power to the grid’s AC power. Our system is a 4.8 KW system, that
should produce about $4500 income this year. Now on a sunny day, my 5 year old
daughter asks “how much energy did we produce?”
Why would you
consider Solar Power?
Be Part of the
Solution. Photovoltaics are an important part of a portfolio of renewable
energy options in Ottawa. Solar panels produce power when it’s most needed during
the day when demand peaks, and where it is needed reducing transmission and
distribution losses. Solar doesn’t
have the huge infrastructure costs and environmental footprint of conventional energy
projects. It also leverages private equity instead of public money to increase
generation capacity.
Ontario has a World
Class Solar Program. Ontario’s Microfit program offers producers a 20 year
contract to at a fixed rate purchase price per kilowatt hour. While the rate
was recently reduced to reflect and further encourage efficiencies in the
supply of new systems, the program still makes solar power attractive.
Ottawa has great
solar potential and limited wind. If you want to make a proactive move in
small-scale renewable energy, solar is a smart choice if you’re living in Ottawa.
If you are thinking about a solar power installation in
Ottawa, here are some considerations to think about.
Do you have a roof
with solar exposure? Ideally you would have near southern exposure to
maximize solar potential. The
orientation of streets in Ottawa are slightly angled so it is likely you won’t
have perfect southern exposure but 15 degrees East or West is still great.
Are you going to have
solar exposure for the next 20 years? Under the microfit program, you sign
a contract with the Ontario Power Authority for 20 years. It’s worth checking
to see if there are development changes around you that could impact your sun exposure.
Can you connect to
the energy grid to sell power where you are? Through the Microfit
application process, Hydro Ottawa can confirm whether the grid near your home would
support a solar installation.
How old is your roof?
Arrays can be moved, but it is best to put an array on a roof that is new, and the
lifetime of the roof meets or exceeds the lifetime of the contract or longer.
How will you finance
the solar project? Ontario’s Microfit program offers a subsidized rate you
will be paid per kilowatt hour, so solar power can be an income generating
project. The upfront cost of the panels and installation can be costly, and is
often the biggest consideration for people considering solar. The payback
period varies on the size of the project – generally the larger the array, the
more energy produced, and the shorter the payback period.
Learning more about
solar Power in Ottawa.
This weekend in Ottawa there’s a great opportunity to learn
more about solar polar! The Second Annual Ottawa Solar Power Fair will be held on June 16th at the Ottawa
City Hall. The fair begins at 9am
and will run till noon. Attendance is free! There will also be a map
available for those interested in touring solar installations around the city.
