Best solar panel angle in Mexico City
Start with 17° facing South for a fixed setup. Compare seasonal options, then confirm the result against your roof, shade, and local weather.
Turn this angle into a roof plan
Start with 17° South in Mexico City, then verify the usable roof area and request installer options.

Planning basis: twelve monthly production estimates.
*Tilt angles are measured from horizontal. Each non-flat result includes the compass direction the panel faces. Gains are estimates based on modeling.
Quick estimate — not a final quote
Good for a quick comparison. For a quote, check your roof, shade, and local weather in a project.
Quote-ready tilt decision
Give installers one fixed-angle target first
Start the quote conversation with 17° South. Seasonal adjustment is only worth pricing if a supplier can show that roughly 4.6% extra production beats the cost, access risk, and warranty complexity of adjustable frames.
Base quote
17° South
Best default for normal roof-mounted systems and the first number to send to installers.
Adjustable option
Winter: 25° South
Summer: 11° South
Four seasonal changes model about 4.6% gain. Monthly adjustment models about 4.6%.
Installer checks
Roof pitch, available rail angles, wind loading, waterproofing, access for cleaning, and whether adjustment affects warranty.
Direction check
In Mexico City, the practical target is a south-facing array. Shade-free roof space, inverter sizing, and battery goals usually matter more than small angle differences.

Is changing the panel angle worth it in Mexico City?
Start with the fixed angle. Four seasonal changes model +69 kWh a year (+4.6%) for each 1 kW of panels. Changing the angle every month adds no modeled annual output beyond the seasonal strategy.
These are latitude-based planning estimates, not a supplier quote. The comparison isolates panel angle; adjustable framing, labour, safe roof access, shade, soiling, and warranty terms can change the practical decision.
