Echo Lake Residence
General Energy Use, Strategies and Systems
Energy Use:
The house it grid tied with 7.7KW PV array mounted on site atop two poles.There are no trackers on the PV, but the owner alters the tilt twice a year to optimise performance.
Energy Strategies:
The owner guessed at the annual energy usage and sized his PV array based on those estimates. Since moving onto the house in 2010, the owner has monitored and reported a small new over-production of electrical energy averaged over the course of each year.
Space conditioning is by a ground source heat pump and a dual fuel arrangement with propane back-up.
