Kaarina, Southwest Finland, Finland is not the most ideal location for generating solar energy year-round due to its position in the Northern Temperate Zone. However, it can still produce a significant amount of energy during certain times of the year.
In summer, each kilowatt (kW) of installed solar panels can generate 5.88 kilowatt-hours (kWh) per day - this is quite good and makes summer an ideal time for solar energy production in this location.
In autumn and winter, however, the output decreases significantly to 1.45 kWh/day and 0.51 kWh/day respectively due to shorter daylight hours and lower sun intensity.
Spring sees an increase again with each kW of installed solar producing about 3.99 kWh per day as daylight hours start to increase.
To maximize total year-round production from these solar panels in Kaarina, Southwest Finland, it's best to tilt them at an angle of 50 degrees towards South - this allows them to capture as much sunlight as possible throughout the different seasons.
As for any local factors that might impede solar production; Kaarina experiences long periods of darkness during winter which significantly reduces potential for electricity generation from solar power during those months. Additionally, Finland's weather is often cloudy which could also limit sunlight availability even on longer days.
There are also environmental concerns such as snowfall or frost that could cover up the panels reducing their efficiency or even causing damage if not properly managed.
Preventative measures that could be taken when installing these panels include using automated systems that can tilt and rotate panels according to sun position maximizing exposure; incorporating sensors and heating elements into panel design so they can automatically defrost themselves when needed; installing protective covers over them during particularly harsh weather conditions etc..
Regular maintenance checks should also be carried out especially after severe weather events ensuring any damage is promptly repaired minimizing downtime thus maximizing productivity.
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 Kaarina
Seasonal solar PV output for Latitude: 60.4072, Longitude: 22.3886 (Kaarina, 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 Kaarina, Finland
To maximize your solar PV system's energy output in Kaarina, Finland (Lat/Long 60.4072, 22.3886) 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 Kaarina, 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 Kaarina, 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 |
|---|---|---|---|
| 43° South in Summer | 62° South in Autumn | 72° 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 Kaarina, 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 Kaarina, 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 Kaarina, Finland
Kaarina is located in the southwest part of Finland, near the city of Turku. The topography of the area is generally flat to gently sloping, with a mix of open fields and forested areas. There are also numerous lakes and water bodies in and around Kaarina.
The region experiences a cold semi-continental climate, with long winters and relatively short summers. However, despite the northern latitude, solar PV can still be viable due to long daylight hours during summer months.
For large-scale solar PV installations, open and flat areas would be ideal to minimize shading and maximize exposure to sunlight. Therefore, agricultural lands or other open spaces could potentially accommodate such projects. However, it's important to consider that Finland's winter months have very few hours of sunlight which might affect efficiency.
It's also worth noting that any large-scale solar project should take into account potential environmental impacts as well as local regulations or restrictions on land use.
One must conduct a detailed site-specific assessment before determining the most suitable locations for large-scale solar PV installations in Kaarina or any other location.
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.
