Solar Energy in Helsinki, Finland
Solar Overview
Helsinki offers an average of 1,831 sun hours annually, which is indicative of its potential for solar energy generation. The typical temperature of 7.5°C plays a role in the efficiency of solar systems installed in the area.
Geographic Impact
Positioned at a latitude of 60.1695°, Helsinki is characterized by its polar/subpolar climate. The geographic location results in varying day lengths throughout the year, influencing solar energy production.
Rating Methodology
With an average solar potential rating, Helsinki's conditions allow for moderate solar energy generation. The annual average of 1,831 sun hours suggests that solar solutions are feasible, though may not reach the levels of higher-rated solar locations.
Understanding the Data
Solar energy production in Helsinki experiences peaks during the summer months, specifically in May, June, and July. This seasonal variation is essential for understanding the optimal times for solar energy use in the city.
Cost & Savings Outlook
Given the electricity price of $0.456/kWh, utilizing solar energy can help offset some electricity costs in Helsinki. While the total savings depend on individual consumption and system size, solar can represent a valuable investment.
How It Compares
Compared to Saint Petersburg and Oslo, which both have a solar potential rating of poor, Helsinki's average rating and higher sun hours present a more favorable option for solar energy investment.
Installation Considerations
At 60.1695° latitude, solar panel installations in Helsinki should be tilted to maximize exposure during summer months while also considering the lower angles of the sun in winter for optimal performance year-round.
Local Incentives
Check local and national incentive programs, which vary by country and region.
Due to Helsinki's latitude, solar production is significantly higher in the summer months, corresponding with extended daylight hours. Conversely, shorter daylight in winter months means lower solar output during that time.
The average temperature of 7.5°C can support efficient solar panel performance, as most panels operate well within this range without excessive heat-related efficiency loss.
