What is TSRF? (Total Solar Resource Fraction)

TSRF quantifies the percentage of the total potential solar energy that a particular site can capture considering its specific conditions. This measurement is used to evaluate whether an area is fit for solar.

What Factors Influence TSRF?

Many factors influence the TSRF. This measurement takes into account all conditions of the site area in order to assess its aptness for solar energy conversion.

Geographical Location

The position of the prospective project on Earth’s surface affects the intensity and duration of sunlight received throughout the year. Places closer to the equator receive more sunlight than polar areas.

Orientation and Tilt of Solar Panels

The direction that the panels face and their angle relative to horizontal will affect the panels’ exposure to sunlight.


Trees, buildings, or terrain might block sunlight from reaching the panels. This must be taken account on the TSRF measurement because heavily shaded areas cannot produce as much solar energy as non-shaded areas.

Atmospheric Conditions

Weather patterns like regular rain, snow, or clouds will reduce the amount of solar energy that the panels are exposed to.

Solar Panel Efficiency

Taking into account the efficiency of the solar panels that will be used for the project is crucial for the TSRF as it varies greatly depending on technology and available resources.
