A lot of progress has been made to Sean & Jaimi's Traditional Net Zero Haven since our last post a couple of months ago. The roof is on, windows are in, insulation is in, drywall is up, the rain screen is nearly complete. And more importantly, the solar panels are up!
The 33 panel system will create an average of 25kWh every day. With electric appliances and heat, it's not clear how much the energy the Hegstad family will use annually. But with rebates currently available, the Hegstad's will receive an annual check from PSE based on the kWh their panels produced.
Solar panel technology has come a long way in the past few years. Previously, it was only recommended to install solar panels exposed to the south and propped at an angle equal to your latitude. For us here in the Northwest, that means 45 degrees (or a 12:12 roof pitch), which is steep. On the Hegstad Residence there are three locations of solar panels: one catching the suns energy from the east, one from the south, and one from the west. And they're not at a very steep slope either.
The next steps are to install the exterior siding and all of the interior trim, cabinets, fixtures and appliances. The exterior color scheme has been narrowed down to two options, but I'll leave the surprise for next time.
