Complete Solar Analysis: Riga, Latvia
Solar Overview
Riga experiences approximately 1,567 hours of sunshine each year, with strongest solar gains in May. This northern location at 56.95° latitude results in highly variable solar production, with extended summer days balanced by dark winters. Solar installations in Riga require thoughtful design and may benefit from energy storage to optimize the limited available solar resource.
Geographic Impact
Located at 56.9496° latitude and 24.1052° longitude, Riga's geographical position significantly impacts its solar potential. At 56.95°, winter solar production faces significant challenges from low sun angles, making south-facing vertical or steep-tilt installations particularly effective.
Rating Methodology
Riga receives a "Poor" rating for solar potential, derived from comprehensive analysis of 1,567 annual sun hours, 9.1°C average temperature, and geographic factors. Lower temperatures enhance panel performance, particularly during clear winter days when cold temperatures combine with reflective snow cover. Riga's conditions enable systems to generate 900-1,100 kWh per installed kW annually, supporting partial energy independence.
Understanding the Data
The following chart shows how solar energy varies month-to-month in Riga. Summer months deliver 48% of the year's solar resource, dramatically exceeding winter's 12% contribution. Understanding this seasonal distribution is crucial for optimal system sizing and accurate financial projections.
⚠️ Note: Notable seasonal variation suggests that battery storage or grid connection helps optimize energy usage across all seasons.
