How to use solar panel tilt angle calculator
- Compare your result with the worked example.
- Check the assumptions and limitations.
WHEN IT HELPS
Common uses
- Find a quick preliminary fixed-panel inclination using the absolute site latitude as a baseline, then apply your own seasonal offset.
Method and assumptions
Tilt (degrees) = clamp(|latitude| + adjustment, 0, 90). Hemisphere determines the approximate equator-facing direction.
Worked example
At 34° N with zero adjustment the rule suggests 34° tilt facing approximately south. A +10° offset gives 44°.
Limitations
This is a rough latitude heuristic, not a solar-yield optimization. Climate, shading, horizon, roof geometry, azimuth and electricity demand affect the true optimum. Near equator use site-specific orientation.
Frequently asked question
Is the latitude angle always optimal?
No. The ideal angle depends on your seasonal load profile and location-specific irradiance.
