What is TSRF?

TSRF stands for Total Solar Resource Fraction. It's a metric used in the solar energy industry to assess the solar potential of a specific location, taking into account factors like shading, panel orientation, and tilt. Essentially, it indicates the proportion of available solar energy that a particular site can convert into electricity. Here is a more detailed breakdown:

• Shading
  • TSRF considers how much sunlight is blocked by obstacles like trees, buildings, or terrain. 
• Panel Orientation and Tilt
  • It also accounts for how solar panels are positioned (facing north, south, east, or west) and their angle relative to the ground.
• Weather Patterns
  • TSRF factors in the typical weather conditions of a location, including cloud cover, rain, and snow.
• Accuracy
  • TSRF provides a more accurate assessment of solar potential than simpler metrics like "Solar Access" or "Tilt and Orientation Factor (TOF)" because it combines these factors, according to New England Clean Energy.
• Importance
  • A higher TSRF value means a site is more suitable for solar energy generation.

In practical terms, TSRF is crucial for: 

• Estimating Solar Energy Production
  • It helps determine how much electricity a solar system is likely to produce at a specific location.
• Optimizing Solar Panel Design
  • It guides the placement and orientation of solar panels for maximum energy output.  
• Incentive Eligibility
  • In some regions, a minimum TSRF may be required for quality solar incentives.
