The $136,000 on a per-home basis was the total capital cost of developing the solar energy system. That cost was primarily funded through all the funding partners, primarily NRCan. If people had had to spend their own money, they would have had to pay $136,000 more for that home. They didn't because the project was primarily funded by the government in order to ensure there were no risks. Customers wouldn't have bought the houses if they had to pay that much more on something that wasn't yet proven.
I'm not sure if tax credits is the right terminology. I really believe that these technologies need to be tested before they become commercially viable. In order to do that, they need to be kick-started through some types of incentives. That funding is where we see that government levels can help these projects get off the ground, be proven, and then become commercially viable once the risks and obstacles and challenges are overcome.
