Best solar panel angle in Quito
Start with 2° facing South — nearly flat — for a fixed setup. At this shallow angle, compass direction has less effect than roof pitch, drainage, shade, soiling, and local weather.
Turn this angle into a roof plan
Start with 2° South in Quito, then verify the usable roof area and request installer options.

Planning basis: summer and winter 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 2° South. 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
2° South
Best default for normal roof-mounted systems and the first number to send to installers.
Adjustable option
Winter: 5° North
Summer: 8° South
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 Quito, 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 Quito?
Start with the fixed angle. Four seasonal changes model +66 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.
