Solar PV Analysis of Kouvola, Finland
The location at Kouvola, Kymenlaakso, Finland is not the most ideal for year-round solar energy generation. However, it can still produce a significant amount of electricity from solar power, especially during certain times of the year.
In summer, you can expect to generate about 5.91 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of installed solar panels. This is when the sun is shining the longest and brightest.
In autumn, this output drops to around 1.39 kWh/day per kW due to shorter days and less intense sunlight.
Winter sees a further drop in production to just 0.50 kWh/day per kW because there's even less daylight and sunlight is weak.
Spring sees an increase again with about 3.98 kWh/day per kW as days get longer and sunnier once more.
To maximize total yearly production from your solar panels in Kouvola, Kymenlaakso, they should be tilted at an angle facing towards south by 50 degrees - this allows them to catch as much sunlight as possible throughout different times of the year.
There are several factors that could potentially impede solar production in Kouvola:
- Weather: Finland experiences long winters with short daylight hours which reduces potential solar energy generation.
- Snow: Heavy snowfall might cover up your panels limiting their exposure to sunlight.
- Cloud Cover: Overcast skies common during Finnish autumns and winters also reduce amount of sunshine reaching your panels
However, these challenges can be mitigated:
- Regular Maintenance: Clearing off any snow or debris on your panels will ensure they receive maximum sunlight.
- Use Tilted Panels: Having panel installations at angles helps shed off snow easily besides optimizing sun exposure.
- Use High-Quality Panels: Some high-quality photovoltaic cells perform better under low-light conditions so investing in such could help improve winter outputs slightly.
Despite these challenges though, remember that even in less-than-ideal conditions, solar panels can still generate electricity and contribute to energy savings.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 56 locations across Finland. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Kouvola
Seasonal solar PV output for Latitude: 60.862, Longitude: 26.7013 (Kouvola, Finland), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 50° South in Kouvola, Finland
To maximize your solar PV system's energy output in Kouvola, Finland (Lat/Long 60.862, 26.7013) throughout the year, you should tilt your panels at an angle of 50° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Kouvola, Finland
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Kouvola, Finland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 50° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 44° South in Summer | 62° South in Autumn | 73° South in Winter | 52° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Kouvola, Finland
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Kouvola, Finland.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Kouvola, Finland
Kouvola, Finland is characterized by a relatively flat topography with an average elevation of around 75 meters above sea level. The area is heavily forested with numerous lakes and rivers throughout the region.
In terms of solar PV suitability, the best areas would be those that are open and receive maximum sunlight exposure throughout the day. This could include cleared land or agricultural fields which are abundant in this region. However, it's important to note that Finland has long winters with short daylight hours which can limit solar energy production during these months.
Additionally, while Kouvola itself may not have high mountains or hills that could obstruct sunlight, its northern latitude means the sun does not rise very high in the sky even at noon (especially during winter), reducing potential solar power output compared to locations closer to the equator.
Another consideration for large-scale solar PV development would be proximity to existing power grids for easy connection and distribution of generated electricity.
Lastly, any plans for large-scale solar PV installations would need careful environmental assessment given the abundance of natural habitats in this region.
Finland solar PV Stats as a country
Finland ranks 59th in the world for cumulative solar PV capacity, with 404 total MW's of solar PV installed. This means that 0.30% of Finland's total energy as a country comes from solar PV (that's 41st in the world). Each year Finland is generating 73 Watts from solar PV per capita (Finland ranks 45th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Finland?
Yes, there are incentives for businesses wanting to install solar energy in Finland. The Finnish government offers a range of financial support and tax incentives for businesses that invest in renewable energy sources such as solar power. This includes grants, loans, and tax deductions. Additionally, the government has set up a feed-in tariff system which guarantees a fixed price for electricity generated from renewable sources such as solar power.
