    *Tilt angles are measured from horizontal. Each non-flat result includes the compass direction the panel faces. Gains are estimates based on modeling.

    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: 26° 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 Buenos Aires, 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 Buenos Aires?

    Start with the fixed angle. Four seasonal changes model +59 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.
