<xs:element minOccurs="0" name="SolarFraction">
<xs:annotation>
<xs:documentation>The Solar Fraction is the portion of the total conventional hot water heating load (delivered energy and tank standby losses). The higher the solar fraction, the greater the solar contribution to water heating, which reduces the energy required by the backup water heater. This value can be found in the OG-300 SRCC Certified Solar Water Heating System Directory.</xs:documentation>

<xs:element minOccurs="0" name="SolarEnergyFactor">
<xs:annotation>
<xs:documentation>The Solar Energy Factor is defined as the energy delivered by the system divided by the electrical or gas energy put into the system. The higher the number, the more energy efficient. This value can be found in the OG-300 SRCC Certified Solar Water Heating System Directory.</xs:documentation>
