This is the yearly energy savings that is the amount of energy provided by the solar technology attributed to a solar feature relative to the total energy requirements.

In discussing annual solar savings, the solar savings fraction or solar fraction (f) should be determined to establish the need for installing solar technology.

The solar savings fraction of a particular system is dependent on many factors such as the load, the collection and storage sizes, the operation, and the climate.

To increase the solar savings fraction, energy conservation measures should be employed first before expanding the size of the solar energy collection system.
