Yesterday SolarCity started the installation of our solar system. They started with the inverter, a Fronius IG Plus 7.5-1 UNI. This will convert the DC current coming from the panels on the roof to AC current. Next to the inverter will be a meter to track the amount of power generated by the panels and an AC disconnect. Now they are just waiting for a nice sunny day to get up on the roof and start the panel installation.

While the solar guys were working in the basement, Warren and I started foaming the rim joist areas. We started in the attic foaming above the top plate. The foam in this area is primarily for air sealing. In other areas of the house it will be used mainly for insulation value in those hard to reach spots, like the rim joist areas because it is too hard to net around the trusses to blow in cellulose.

We started in the attic because we wanted to get use to the two part foam kit, and perfect the spraying technique before heading to the more critical areas at the first and second floor rim joist areas.
