30k though is current price when installed separately. Currently solar panel + equip are already just 40% of the cost. When solar panel will be build into the design of the new construction and done by the contractor the installation cost will come down a lot. Plus as solar panel are in the design of the construction they could be better placed for optimal efficiency increasing the rate of return. My guess is by 2020 when it becomes mandatory it will actually cost maybe around 15k and save the owner a lot more over it's lifetime.
