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.
