Solar PV Analysis of Iisalmi, Finland
The location at Iisalmi, North Savo, Finland is not ideal for generating energy via solar PV year-round due to its position in the Northern Temperate Zone. The amount of electricity that can be produced from solar power varies greatly throughout the year. During summer, you can expect to generate a decent amount of electricity - about 5.76 kWh per day for each kW of installed solar capacity. This is because during summer, days are longer and sun shines more directly on this part of the world.
However, during autumn and winter, the output drops significantly to 1.12 kWh/day and 0.38 kWh/day respectively due to shorter daylight hours and less direct sunlight as a result of Earth's tilt away from the sun during these seasons.
Spring sees an increase again with around 3.81kWh/day per kW as days start getting longer again towards summer.
For a fixed panel installation at this location, tilting panels at an angle of 52 degrees facing south would maximize total annual production from solar PV by capturing most available sunlight throughout different times in a year.
As far as environmental or local factors that could impede solar production are concerned; one significant factor could be snowfall during winters which may cover panels thereby reducing their efficiency drastically until cleared off.
Also given its northern location there will likely be long periods without much daylight in winter months which will hamper generation potential further.
To mitigate these issues it would be advantageous to install systems for automatic snow removal or heating elements that prevent accumulation on panels themselves if possible within budgetary constraints.
Another consideration might also include ensuring installations are robust enough withstand potentially high wind loads often associated with stormy weather conditions common in northern climates like Finland's.
Overall while it is certainly possible generate some power using Solar PV in Iisalmi it wouldn't provide consistent output throughout entire year compared locations nearer equator where sunlight intensity and duration remains relatively constant all year round.
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 Iisalmi
Seasonal solar PV output for Latitude: 63.5723, Longitude: 27.1992 (Iisalmi, 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 52° South in Iisalmi, Finland
To maximize your solar PV system's energy output in Iisalmi, Finland (Lat/Long 63.5723, 27.1992) throughout the year, you should tilt your panels at an angle of 52° 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 Iisalmi, 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 Iisalmi, Finland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 52° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 46° South in Summer | 64° South in Autumn | 74° South in Winter | 55° 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 Iisalmi, 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 Iisalmi, 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 Iisalmi, Finland
Iisalmi, Finland is located in the northern part of the country and is characterized by a relatively flat topography with numerous lakes and forests. The elevation ranges from around 90 to 170 meters above sea level.
The region experiences long, cold winters and short, mild summers due to its close proximity to the Arctic Circle. It has a subarctic climate with significant snowfall during winter months. The amount of sunlight varies greatly throughout the year, with nearly 24 hours of daylight in mid-summer (June) and only few hours during mid-winter (December).
For large-scale solar photovoltaic (PV) installations, areas that are most suited would be those that have maximum sun exposure throughout the year. This means open areas without shade from trees or buildings would be ideal.
However, given Iisalmi's high latitude and climatic conditions, it may not be as suitable for large-scale solar PV compared to locations closer to the equator which receive more consistent sunlight throughout the year.
Nonetheless, advancements in technology have made it possible for solar panels to generate electricity even in less sunny climates like Finland's. In fact, there are already several solar power plants operating in different parts of Finland.
To maximize efficiency for a potential large-scale solar PV project near Iisalmi:
1. Consider south-facing sites as they will receive more sunlight.
2. Avoid forested or built-up areas where shading could reduce panel efficiency.
3. Choose flatter terrains where installation would be easier.
4. Proximity to power grids can also influence site suitability as this reduces costs related to energy transmission.
5. Use advanced PV modules designed specifically for colder climates that perform well under low light conditions and can withstand heavy snow loads.
In conclusion: while Iisalmi might not offer optimal conditions for large scale Solar PV due its location far north; careful planning considering local topographical features along with use of advanced technologies can still make solar PV projects feasible in the 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.
