solar panels

2014 05 31: the sunpower solar panels are installed constituting a part of a nominal 6 kW system. i like the all black appearance of the sunpower panels and their exceptionally high efficiency. sunpower uses silicon solar cells, which i think will degrade less than the thin film cells. jason brennan at aurora-energy was responsible for the install. he and his crew did a great job. jason was also kind enough to re-schedule some other work to accomodate my schedule needs, which i thought was an exceptional kindness. you can  reach him at 410 268 3088.

plumbing and wiring

2013 12 19: most of the plumbing and the wiring are completed.

although not shown in the picture, there are three colors of wire used in the house. yellow wire is 12 gage and goes to all the outlets. this is somewhat unusual. excepting the kitchen and bathroom, most outlets in most houses are a lighter gage, 14. the white wire is 14 gage and goes to light fixtures. orange wire is really heavy gage and goes to the point of use hot water heaters and the dryer.

the picture also shows some orange pipe. this is used to provide water to a sprinkler system.

exterior electrical

2013 11 10: the wiring for the exterior outlet shown in this picture and for all the exterior outlets comes from the detached garage rather than from the house. this decreases the opportunities for air leaks and eliminates a thermal bridge.

the wiring to the porch light is fed through the slab reducing the again reducing the chance of air leaks and reducing a thermal bridge.
