Solar PV Analysis of Raisio, Finland
The location at Raisio, Southwest Finland, Finland is not ideal for year-round energy generation through solar PV due to its position in the Northern Temperate Zone. However, it does have potential during certain times of the year.
In simpler terms, this means that while you can generate some electricity from solar panels in Raisio throughout the year, it's not going to be as effective as in some other places. The amount of electricity you can expect to produce varies with each season:
- In summer, your solar panels would perform best and generate about 5.88 kilowatt-hours (kWh) per day for each kilowatt (kW) of solar installed.
- In autumn and spring, they'd do okay - generating about 1.45 kWh/day per kW in autumn and around 4 kWh/day per kW in spring.
- Winter would be tough though - with just about half a kWh/day produced per kW installed because of less sunlight.
For a fixed panel installation at this location, tilting the panels towards south at an angle of 50 degrees will maximize total yearly production from solar PV.
There are several factors that could potentially hinder solar production here:
1. Weather: As mentioned earlier, winter months have significantly less sunlight which reduces energy output.
2. Snowfall: Heavy snowfall can cover up the panels reducing their efficiency or even causing damage.
3. Temperature: Solar panels actually become less efficient as temperature increases above certain levels so very cold temperatures might affect their performance too.
To overcome these challenges:
1. Regular maintenance including clearing off any snow on the panels should be carried out especially during winter months.
2. Use high-quality durable materials that withstand extreme weather conditions such as heavy snowfall or freezing temperatures.
3. Consider installing adjustable tilt mounts so that you can change the angle depending on time of year to capture maximum sunlight.
Overall while there are definitely challenges associated with setting up a solar PV system in Raisio, Southwest Finland, Finland, it's not impossible and can still be a viable option especially during non-winter months.
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 Raisio
Seasonal solar PV output for Latitude: 60.4916, Longitude: 22.0881 (Raisio, 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 Raisio, Finland
To maximize your solar PV system's energy output in Raisio, Finland (Lat/Long 60.4916, 22.0881) 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 Raisio, 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 Raisio, 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 Raisio, 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 Raisio, 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 Raisio, Finland
Raisio, Finland is located in the southwestern part of the country and is part of the region known as Southwest Finland. The topography of this area is generally flat with low-lying plains and scattered small hills. There are numerous lakes and rivers throughout the region, along with forests that cover a significant portion of the land.
Regarding solar PV potential, it's important to note that Finland's latitude means it experiences long days in summer but very short days in winter, which affects annual solar energy production. However, during summer months when sunlight hours are at their peak, there can be good potential for solar power generation.
Flat open areas would be most suited for large-scale solar PV installations to avoid shading from trees or buildings. Areas such as agricultural lands or other open spaces could be potential sites. Proximity to existing grid infrastructure would also be a consideration to minimize costs associated with transmitting electricity generated by the solar panels.
However, any plans for large-scale solar projects would need careful assessment including local climate data (like cloud cover), land availability and use restrictions, environmental impact assessments etc., before determining their feasibility and efficiency.
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.
