摘要

1. 11724 -8064 (PV Provided) = 3665 kWh 2. Distance to Zero Net Energy on this house currently: 3665 kWh x $0.174/kWh = $638/year 3. Radiant heat spacing and layout provided uniform delivery temperature throughout the house 4. Specific details about the energy used in auxiliary heating of DHW & living space to be identified more precisely in the improved energy monitoring system 5. If the three vertical wall-mounted collectors were re-mounted @ 45°, the additional savings would reduce the distance to Zero Net Energy on this house to $366/year.
