Today we had the guys from C-Solar out to the Rowayton,CT house to map out the PV and Solar Thermal systems. The roof faces due solar south- perfect orientation - (because we planned it that way!)and we have 2 different roof slopes. The main roof will be optimal for winter sun PV and year round solar thermal. The big shed dormer provides and excellent angle for the summer sun. We can easily fit a 10kW PV system alone, OR 7.5kW PV system with 3 or 4 solar thermal panels for hot water. The guys are going to crunch the numbers (show us the rebates and tax incentive numbers and energy use estimates) and then the client will decide which way to go.
This house also has a geothermal system.
With these three systems working together- as well as the super energy efficient building envelope, LED can lights throughout, low flow plumbing fixtures, and energy saving controls - the client will see a great reduction of grid based energy use. We will tell you the exact break down of numbers later after all is up and running.
Now we just have to pick a floor stain color...
70 degrees and sunny! Happy spring.
