Solar PV Analysis of Bitola, North Macedonia
The location in Bitola, North Macedonia, situated at latitude 41.0315 and longitude 21.3335, presents a mixed scenario for year-round solar PV energy generation. This Northern Temperate Zone location experiences significant seasonal variations in solar energy production, which impacts its overall suitability for solar power installations.
Seasonal Solar Energy Production
Solar energy output at this location varies considerably throughout the year. Summer proves to be the most productive season, with an impressive daily output of 7.37 kWh per kW of installed solar capacity. Spring follows as the second most productive season, generating 5.54 kWh per day. However, autumn and winter see a substantial decrease in energy production, with 3.36 kWh and 2.21 kWh per day, respectively.
These figures indicate that the location is highly favorable for solar energy production during the warmer months, particularly from late spring through early autumn. However, the significant drop in output during the colder months suggests that alternative energy sources or energy storage solutions may be necessary to maintain consistent power supply year-round.
Optimal Panel Installation
To maximize year-round solar energy production at this location, fixed solar panels should be installed at a tilt angle of 35 degrees facing South. This optimal angle takes into account the site's latitude, the Earth's elliptical orbit, and seasonal variations in solar elevation angles.
Environmental and Weather Considerations
While Bitola's location is generally conducive to solar energy production, there are some environmental factors to consider:
- Winter snowfall: Bitola experiences snowfall during winter months, which can potentially cover solar panels and reduce their efficiency. Regular panel cleaning and the use of snow-shedding systems can help mitigate this issue.
- Air pollution: As an industrial city, Bitola may experience periods of increased air pollution, which can slightly reduce solar panel efficiency. Installing panels at a higher elevation or using self-cleaning panel technologies can help address this concern.
Despite these challenges, with proper installation techniques and maintenance practices, solar PV systems in Bitola can still achieve good energy production levels, particularly during the longer, sunnier days of spring and summer.
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 25 locations across North Macedonia. 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 Bitola
Seasonal solar PV output for Latitude: 41.0315, Longitude: 21.3335 (Bitola, North Macedonia), 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 35° South in Bitola, North Macedonia
To maximize your solar PV system's energy output in Bitola, North Macedonia (Lat/Long 41.0315, 21.3335) throughout the year, you should tilt your panels at an angle of 35° 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 Bitola, North Macedonia
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 Bitola, North Macedonia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 25° South in Summer | 45° South in Autumn | 55° South in Winter | 33° 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 Bitola, North Macedonia
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 Bitola, North Macedonia.
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 Bitola, North Macedonia
The area around Bitola, North Macedonia, is characterized by a diverse and interesting topography. The city itself is situated in the southern part of the Pelagonia valley, a large and relatively flat basin surrounded by mountains. This valley is one of the most significant agricultural regions in North Macedonia, known for its fertile soil and expansive fields.
To the east of Bitola, the terrain gradually rises towards the Baba Mountain range, which includes the prominent peak of Pelister. This mountain area is part of Pelister National Park, known for its rugged landscapes, dense forests, and alpine meadows. The western side of the valley is bordered by the Buševa Mountains, which are generally lower in elevation compared to the Baba range.
The city itself sits at an elevation of around 615 meters (2,018 feet) above sea level, providing a mild climate despite its inland location. As you move away from the city center, the land gently slopes upward, creating rolling hills and eventually giving way to more pronounced mountainous terrain.
Regarding areas suitable for large-scale solar PV (photovoltaic) installations, the Pelagonia valley offers several promising locations. The relatively flat terrain of the valley floor, particularly to the north and northwest of Bitola, would be well-suited for solar farms. These areas benefit from:
- Abundant open space with minimal shading from geographical features
- Good sun exposure due to the lack of tall obstacles
- Easier access for construction and maintenance
- Proximity to existing power infrastructure, as Bitola is home to a major power plant
However, it's important to note that much of this flat land is currently used for agriculture, which may create competition for land use. As an alternative, some of the gentler slopes in the foothills surrounding the valley could also be considered for solar installations. These areas might offer the advantage of slightly better sun angles, especially on south-facing slopes, while having less impact on prime agricultural land.
Any large-scale solar project would need to carefully balance energy production potential with environmental and agricultural considerations, as well as take into account local regulations and grid connection capabilities. Detailed site-specific studies would be necessary to determine the most optimal locations for solar PV development in the region.
