Easily determine your roof's pitch and angle for optimal solar panel installation. Use our free Solar Roof Pitch Calculator to get accurate results in seconds—no complex math required. . For a fixed system (95% of residential installs), the Golden Rule is to tilt your panels at an angle equal to your Latitude. This averages out the sun's position over 365 days. Roof Pitch to Degrees Conversion Chart Roofers speak in "Pitch" (Rise over Run), while solar installers speak in. . Our solar panel angle calculator takes the guesswork out of panel positioning, suggesting panel tilt angles based on your location's latitude and your willingness to reposition based on the sun's seasonal dance across the sky. A correctly tilted system can improve efficiency by 5–10% annuall y, reducing payback time and boosting long-term savings. Before diving into specific recommendations, it's. .
