Best solar panel angle in Montevideo

Start with 33° facing North 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 33° North in Montevideo, 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 33° North. Seasonal adjustment is only worth pricing if a supplier can show that roughly 4.7% extra production beats the cost, access risk, and warranty complexity of adjustable frames.

Base quote

33° North

Best default for normal roof-mounted systems and the first number to send to installers.

Adjustable option

Winter: 40° North

Summer: 27° North

Four seasonal changes model about 4.7% gain. Monthly adjustment models about 4.7%.

Installer checks

Roof pitch, available rail angles, wind loading, waterproofing, access for cleaning, and whether adjustment affects warranty.

Direction check

In Montevideo, the practical target is a north-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 Montevideo?

Start with the fixed angle. Four seasonal changes model +60 kWh a year (+4.7%) 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.
