Vienna Sun Hours: Understanding Your Solar Investment
Solar Overview
Solar installations in Vienna can expect 1,997 sun hours per year, with optimal generation during June. The 48.21° latitude location provides moderate seasonal solar variation, with spring and fall offering balanced production levels. Solar installations in Vienna are moderately productive, making them viable especially for offsetting high electricity costs.
Geographic Impact
The specific coordinates of 48.2082°N, 16.3738°E establish Vienna's unique solar energy potential. At 48.21°, solar panels benefit from reasonable sun angles year-round, though winter production remains 30-40% below summer peaks.
Rating Methodology
The "Average" solar potential rating for Vienna is based on multiple factors including annual sun hours (1,997), average temperature (13.5°C), and seasonal variability. Cool temperatures support excellent panel efficiency, though snow accumulation may be a consideration during winter months. The moderate solar resource supports payback periods of 10-15 years for residential systems, particularly when incentives are available.
