Solar PV Analysis of Nokia, Finland
The location at Nokia, Pirkanmaa, Finland is not ideal for generating energy via solar PV year-round due to its position in the Northern Temperate Zone. This is because the amount of sunlight it receives varies greatly throughout the year.
During summer, this location can generate a substantial amount of electricity from solar power, with an average output of 5.78kWh per day for each kW of installed solar. This makes it an excellent time to harness solar energy.
However, during autumn and winter, the expected output drops significantly to 1.28kWh/day and as low as 0.46kWh/day respectively due to shorter daylight hours and lower sun intensity common in these seasons in northern locations like Finland.
In spring, there's improvement with an average output rising up to 3.95kWh per day but still less than summer's potential.
For a fixed panel installation at this location, panels should ideally be tilted at an angle of 51 degrees facing south which allows them to capture maximum sunlight over the course of a year considering sun’s path across sky changes seasonally.
There are several environmental or weather factors that could impede solar production here; most notably being snowfall during winter months which may cover panels reducing their efficiency or even stopping production entirely if they're completely covered by snow. Additionally heavy cloud cover common in Finnish winters can also reduce sunlight reaching panels further lowering their productivity.
To prevent such issues and ensure greater energy production:
1) Regular maintenance including clearing off any accumulated snow on your panels can help keep them working effectively.
2) Using automated systems or employing tilt-able mounts that allow changing angle depending on season might be beneficial.
3) Installing more efficient types of photovoltaic cells that perform better under low light conditions could also improve performance during darker months.
4) Finally using battery storage systems would allow storing excess power produced during sunny periods for use later when sunshine isn't sufficient enough for power production.
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 Nokia
Seasonal solar PV output for Latitude: 61.4889, Longitude: 23.4711 (Nokia, 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 51° South in Nokia, Finland
To maximize your solar PV system's energy output in Nokia, Finland (Lat/Long 61.4889, 23.4711) throughout the year, you should tilt your panels at an angle of 51° 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 Nokia, 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 Nokia, Finland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 51° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 45° South in Summer | 63° 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 Nokia, 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 Nokia, 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 Nokia, Finland
Nokia, Finland is located in the southern part of the country. The topography around Nokia is generally flat to gently rolling, with numerous lakes and forests. The city itself sits on the banks of Nokianvirta River.
In terms of solar PV potential, it's important to note that Finland has a relatively low solar insolation level due to its high latitude. However, this doesn't mean that solar power is unviable; instead, it just requires more careful planning and design for maximum efficiency.
Flat areas would be most suitable for large-scale solar PV installations as they allow for easier installation and maintenance while maximizing exposure to sunlight. Areas with minimal shading (i.e., away from dense forests) would also be ideal.
The region north/northeast of Nokia appears less forested according to satellite imagery and could potentially serve as viable locations for large-scale solar farms.
However, before any decisions are made about specific locations, detailed studies need to be conducted including analysis of local weather patterns, land use restrictions and environmental considerations.
It might also be worth considering floating photovoltaic systems on some larger lakes nearby if land space is limited or protected - such technology has been successfully implemented in other regions with similar conditions like Sweden or Netherlands.
Lastly but importantly: despite lower levels of sun irradiation compared to countries closer towards equator - thanks to technological advances even higher latitudes can harness renewable energy through photovoltaics effectively during summer months when days are long in Finland.
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.
