Despite the solar array facing east, which reduces it's energy output by approximately 20%, the roof of the Olive and Wallace building fits this 30 kW solar array perfectly. Mechanically, the array consists of 96 all-black monocrystalline solar modules configured in 6 even rows of 16. Electrically, the array is divided into three separate inverter systems to feed three individually-metered units in the building, which house Grizzly Creek Films
, Gallatin Valley Land Trust
, and Wildlife Conservation Society
. Online data-monitoring of the inverters allows easy insight to the performance of the system for the owners.
The system will produce an estimated 30280 kWh per year and will offset 100% of the current electrical demand of the aforementioned companies. With the assistance of a 30% tax credit, an accelerated corporate depreciation schedule, and a 25% grant from the USDA, financial payback on the system is estimated at 7 years.
The 25 year energy production of the system is equivalent to offsetting carbon emissions from 534,914 lbs of burned coal, offsetting greenhouse gas emissions from 106 passenger vehicles driven in a year, and offsetting greenhouse gas emissions from 159 tons of waste dumped in a landfill.
