Solar PV Analysis of Rekikoski, Finland
The location at Rekikoski, Satakunta, Finland is not the most ideal place for generating solar energy all year round due to its position in the Northern Temperate Zone. However, it's not impossible and does have periods of good solar production.
During summer, you can expect a decent amount of energy from solar panels with about 5.78 kilowatt-hours (kWh) produced per day for each kilowatt (kW) of installed solar. Spring also offers reasonable production with around 3.95 kWh/day per kW of installed solar.
On the other hand, autumn and winter have significantly lower energy production rates due to shorter daylight hours and lower sun angles. In autumn, you can expect about 1.28 kWh/day per kW of installed solar and in winter this drops even further to just 0.46 kWh/day per kW.
To maximize total year-round production from your solar panels at this location, they should ideally be tilted at an angle facing 50 degrees South.
Now let's talk about local factors that could affect your ability to generate power from the sun here:
Finland experiences long winters with heavy snowfall which could cover your panels reducing their effectiveness or even damage them if not properly managed. To prevent this issue, you should ensure regular snow removal from your panels during winter months or consider installing them at steeper angles so that snow slides off more easily.
Also note that Finland has many cloudy days throughout the year which could reduce sunlight reaching your panels leading to less electricity generation than anticipated based on direct sunlight calculations alone.
The surrounding topography might also impact your system’s performance depending on whether there are any large structures or natural features like mountains casting shadows over where you plan to install your system - so site selection is important too!
In conclusion: while Rekikoski isn't necessarily an ideal location for year-round high-volume solar power generation due its climate and position on earth, with the right set-up and maintenance you can still harness a decent amount of solar energy particularly during the sunnier 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 Rekikoski
Seasonal solar PV output for Latitude: 61.1994, Longitude: 22.8797 (Rekikoski, 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 Rekikoski, Finland
To maximize your solar PV system's energy output in Rekikoski, Finland (Lat/Long 61.1994, 22.8797) 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 Rekikoski, 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 Rekikoski, 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 | 53° 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 Rekikoski, 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 Rekikoski, 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 Rekikoski, Finland
Rekikoski, Finland is located in a region characterized by a mix of flat and hilly terrain. The area is heavily forested with numerous lakes and rivers interspersed throughout. The land gradually rises towards the north and east into more mountainous regions.
As for solar PV potential, the following factors should be considered:
1. Sunlight: Finland does not receive as much sunlight as countries closer to the equator due to its high latitude location. However, during summer months it benefits from long daylight hours.
2. Land Use: Large-scale solar installations require large tracts of open land. In Rekikoski, such areas could potentially be found in cleared or agricultural lands that are not heavily forested or hilly.
3. Proximity to Infrastructure: Solar farms need to be close enough to existing power infrastructure for easy connection to the grid.
4. Environmental Impact: Areas that are not ecologically sensitive or home to protected species would be preferable for large-scale solar installation.
Considering these factors, suitable areas for large-scale solar PV around Rekikoski might include open agricultural lands where tree cover is low and access to infrastructure can be easily achieved without causing significant environmental disruption.
However, given Finland's relatively low levels of sunlight (especially in winter), any decision about installing large scale solar PV would need careful cost-benefit analysis considering other renewable energy options like wind power which might have higher potential in this region.
Remember also that local regulations regarding land use must always be taken into account when planning such installations.
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.
