I agree with ibjames. I don’t think solar panel looks cool. In fact, I think it’s quite ugly and out of sync with the overall flow of a house. However I’ve always respected those willing to disrupt the look of their home in order to be green.
Even with government’s support, I believe the cost needs to come down by at least another 20% before it’s a worthy investment for average Joe like me. Looking at the technology trend, we should only need to wait about 2 more years before that price point will be reached.
