General Energy Use, Strategies and Systems

Energy Use:

The Hitchcock Center's building uses a 60kw photovoltaic array comprised of Sunpower SPR-E20-327-COM modules. Solaredge inverters convert DC to AC current.

Renewable Energy System Description & Details
The Hitchcock Center's building uses a 60kw photovoltaic array comprised of Sunpower SPR-E20-327-COM modules. Each panel has an area of 1.63 square meters so each panel will produce 1.13kWhr per day per panel on your system. Annually the solar system can produce an average of 76,134 kilowatt hours per year (provided no shade grows that will effect production). SolarEdge inverters are used to convert DC to AC current. Note that the power rating is 60,495 Watts DC, 54,000 Watts AC.
Annual renewable energy generated 64,887 kWh

Storage and Installed Capacity

As noted above, the northeast grid stores excess electric energy. We have not calculated the thermal mass impact on the overall energy demand of the building.

Energy Storage type

Building uses the northeast energy grid to store excess power, plus there is thermal mass in the floor slab that stores some heat energy during the day and deliver it at night.
