Positioning solar panels at an optimal angle is essential for maximizing sun exposure, particularly in winter when the sun is lower in the sky. A tilt angle that accounts for local latitude can be calculated to ensure that panels receive the most sunlight, even during overcast days. Adjusting for seasonal shifts in the sun’s path will enhance overall energy capture.

Moreover, thoughtful location selection plays a significant role in ensuring performance. Selecting spots that are less prone to shade from trees or nearby buildings is critical. Additionally, planning for potential obstructions throughout the year — such as leaf drop in autumn — can increase effectiveness throughout the seasons. By adopting a forward-thinking approach to planning and positioning, solar street lights will remain operational despite the challenges posed by winter weather.
