Hi Judy, there are a number of good companies that provide solar installation in Ottawa, but I have found iSolara Solar Power to be one of the most reliable and friendly companies to deal with. Here is there website if you can visit http://www.isolara.com/ to get what information you want.
We went with iSolara to install our Solar Panels. I highly recommend them. They helped us swim through all the red tape and tangles that are necessary to get approval as a MicroFit program. Their installation and after service support is great.
