Best solar panel angle in Vienna
Start with 46° 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 46° South in Vienna, then verify the usable roof area and request installer options.
1. Best fixed tilt & direction
46°
46° facing South. Set it once for the entire year.
Planning basis: latitude and estimated annual solar production.
2. Two adjustments / year
Winter: 53° South
Summer: 40° South
Provides a 1.5% gain over the best fixed tilt.
Planning basis: summer and winter production estimates.

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 46° 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
46° South
Best default for normal roof-mounted systems and the first number to send to installers.
Adjustable option
Winter: 53° South
Summer: 40° 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 Vienna, the practical target is a south-facing array. Shade-free roof space, inverter sizing, and battery goals usually matter more than small angle differences.
Adjustment payoff · 1 kW reference array
Is changing the panel angle worth it in Vienna?
Start with the fixed angle. Four seasonal changes model +48 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.
