This tool estimates the optimal tilt (angle) for a fixed‐mount solar panel based on your latitude. Adjusting your panels to the right angle can increase yearly energy yield by up to 20 %.
The optimal tilt angle for solar panels typically equals your location's latitude. You can fine-tune this by subtracting 10-15 degrees for summer optimization or adding 10-15 degrees for winter.
Optimizing your solar panel angle is essential for maximizing energy production. Start by understanding tilt basics and determining your latitude. Make seasonal adjustments, tilting panels flatter in summer and steeper in winter.
Installation costs vary significantly by pitch: Steep roofs (35°+) can increase installation costs by 15-30% due to enhanced safety requirements and specialized equipment, while flat roofs may need additional tilt hardware costing $0.

An easy method for determining solar panel tilt is to match the latitude of your home. This can vary depending on your north-south location, but it generally ranges from 30-45 degrees for homeowners in the continental United States.
The FLIR PV78 is designed for solar site surveys, panel installation, and maintenance of photovoltaic systems. It allows for instant measurements to determine solar (irradiance in watts per square meter) as required by IEC 62446-1 Electrical Safety of PV installations standard.
In South Africa, most home solar panels are installed at an angle of 20 to 35 degrees, based on a general all-year-round ideal average and the slant of most roofs.
This guide explains how solar panel angle affects production, how to estimate the best tilt for your location, and when small angle changes make a meaningful difference in real-world performance.
