I am planning on taking a solar Technologies course this winter, and afterwards, I’m planning on opening up a company, that sells, and installs for people, and in which case we would also be envolved with the windmills. I’m just wondering if this would be a good investment, and if people in Canada think its something that they would be interested in having?

Not yet. Solar is still inefficient and not cost effective. Solar companies have continuously underperformed. Solar wil not take off when the next step in technology is finally available, but who knows when.
