Solar PV Analysis of Panevezys, Lithuania
Panevezys, Panevėžys, Lithuania, situated at latitude 55.7385 and longitude 24.3506, presents a challenging location for year-round solar PV energy generation. This Northern Temperate Zone city experiences significant seasonal variations in solar output, which greatly impacts the efficiency of solar installations.
Seasonal Solar Performance
The solar energy production in Panevezys fluctuates dramatically throughout the year. Summer stands out as the most productive season, with an impressive 5.94 kWh per day for each kW of installed solar capacity. Spring follows as the second-best season, generating 4.05 kWh daily. However, autumn sees a substantial drop to 2.01 kWh per day, while winter plummets to a mere 0.90 kWh daily output.
These figures highlight the stark contrast between the warm and cold months, with summer producing over six times more energy than winter. The ideal times for solar generation are clearly from late spring through early autumn, when daylight hours are longer and the sun's angle is more favorable.
Optimal Panel Installation
To maximize year-round solar production in Panevezys, Panevėžys, fixed solar panels should be tilted at a 46-degree angle facing south. This optimal angle helps capture the most sunlight possible throughout the year, considering the city's northern latitude and seasonal sun path variations.
Environmental and Weather Factors
Several factors can impede solar production in Panevezys:
- Long, dark winters with very short daylight hours
- Frequent cloud cover, especially during autumn and winter
- Potential snow accumulation on panels during winter months
To mitigate these challenges, consider implementing the following measures:
- Use high-efficiency solar panels designed for low-light conditions
- Install snow-shedding systems or manual cleaning mechanisms
- Implement a dual-axis tracking system to maximize light capture
- Consider supplementing with other renewable energy sources during winter
While Panevezys's location presents significant challenges for year-round solar energy production, careful planning and appropriate technology can still make solar PV a viable part of the local energy mix, particularly during the more favorable months of the year.
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 16 locations across Lithuania. 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 Panevezys
Seasonal solar PV output for Latitude: 55.7385, Longitude: 24.3506 (Panevezys, Lithuania), 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 46° South in Panevezys, Lithuania
To maximize your solar PV system's energy output in Panevezys, Lithuania (Lat/Long 55.7385, 24.3506) throughout the year, you should tilt your panels at an angle of 46° 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 Panevezys, Lithuania
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 Panevezys, Lithuania. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 46° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 39° South in Summer | 58° South in Autumn | 68° South in Winter | 47° 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 Panevezys, Lithuania
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 Panevezys, Lithuania.
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 Panevezys, Lithuania
The area around Panevezys, Lithuania, is characterized by a relatively flat and gently rolling landscape. This region is part of the Northern Lithuanian Lowland, which is a broad, low-lying plain that covers much of northern Lithuania. The terrain around Panevezys is predominantly composed of glacial deposits, resulting in a mix of sandy and clayey soils.
The topography in this area is generally uniform, with only slight variations in elevation. Small hills and shallow valleys occasionally punctuate the landscape, but there are no significant mountains or steep slopes nearby. The Nevezis River, which flows through Panevezys, has carved a shallow valley in the surrounding plain, creating some minor topographical features along its course.
Due to its flat nature, the region around Panevezys receives ample sunlight throughout the year, making it potentially suitable for large-scale solar PV (photovoltaic) installations. The areas most suited for such projects would likely be found in the open agricultural lands surrounding the city. These spaces offer large, unobstructed areas with minimal shading from trees or buildings, which is ideal for maximizing solar energy production.
Specifically, the rural areas to the south and east of Panevezys might be particularly well-suited for solar PV development. These regions tend to have more expansive, open fields with fewer settlements, potentially providing the necessary space for large solar arrays. Additionally, the slightly elevated areas within the generally flat landscape could offer advantages in terms of reduced risk of flooding and potentially better exposure to sunlight.
However, it's important to note that while the topography is favorable, other factors such as local zoning regulations, grid connectivity, and environmental considerations would also play crucial roles in determining the most suitable locations for large-scale solar PV projects in the vicinity of Panevezys.
Lithuania solar PV Stats as a country
Lithuania ranks 61st in the world for cumulative solar PV capacity, with 338 total MW's of solar PV installed. Each year Lithuania is generating 121 Watts from solar PV per capita (Lithuania ranks 36th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Lithuania?
Yes, there are incentives for businesses wanting to install solar energy in Lithuania. The Lithuanian government offers a range of financial incentives and tax breaks for businesses that invest in renewable energy sources such as solar power. These include grants, loans, and tax credits. 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. This helps to make investing in solar energy more attractive to businesses.
