CASE STUDY NO. 2
ROSECRANS PLACE
(Below) Plan diagram for the general location of the so- lar PV arrays on townhouse Building 4 and Building 3. This is typical for all the buildings in the Rosecrans Place project.
Renewable On-Site Energy Supply
Solar Photovoltaic System
This entire multifamily portion of the project is featured as a community of “Solar-Powered Town- homes and Live/Work Units”, so the solar photovoltaic system that is part of each basic unit is one of the most attractive selling points for the development. Every unit is equipped with a roof- mounted system that generates 2.76 kilowatts, which is estimated to offset about 30% of the anticipated electrical load.
The solar panels are 460w CanadianSolar, Model HiKu High Power Mono Perc Module. There are six panels to each array, which measures 10’-4” x 13’-10” set on a support structure on the flat roof of each building. These solar PV arrays are part of the individual unit but are cleaned and maintained by the Rosecrans Place Homeowners Association (HOA).
The DC power from these panels are converted efficiently to AC power by Enphase IQ8 micro- inverters.
