Solar Roof Analysis Calculator
Analyze roof space and shading to determine solar potential
About this calculator
The Solar Roof Analysis Calculator evaluates your roof's solar energy potential by analyzing available space, orientation, pitch, and shading factors. This tool helps homeowners determine if their property is suitable for solar panel installation and estimates the maximum solar capacity their roof can accommodate. By considering obstacles like chimneys, vents, and nearby trees or buildings that create shade, the calculator provides accurate assessments for making informed solar investment decisions.
How to use
Enter your roof dimensions, select the roof pitch and orientation, then identify any obstacles or shading sources like trees, buildings, or roof features. The calculator will analyze the usable roof space and shading impact to determine your property's solar potential and recommended panel placement areas.
Frequently asked questions
What roof orientations work best for solar panels?
South-facing roofs are ideal, but east and west orientations can also generate significant solar energy with proper panel placement.
How does shading affect solar panel performance?
Even partial shading can reduce solar output by 20-40%. The calculator identifies problem areas to optimize panel placement.
What minimum roof space do I need for solar panels?
Typically 100 square feet minimum for a small system, though larger unshaded areas provide better energy production potential.
