Solar Fraction for Water Heating Model

As of SAM 2011.12.2, the solar water heating model reports the solar fraction in the metrics table.

Solar Fraction Metric

The equation is:

Solar Fraction = Total Solar Energy Delivered to Tank (kWh) / Total Energy Delivered to Tank (kWh)

Where Total Energy Delivered to Tank is the sum of Solar Energy Delivered to Tank and Auxiliary Energy Delivered to Tank.
