The location of Plasnica, North Macedonia, situated at 41.4707°N, 21.1152°E, presents a mixed picture for solar PV energy generation throughout the year. This Northern Temperate Zone location experiences significant seasonal variations in solar output, which impacts its overall suitability for year-round solar energy production.
Seasonal Solar Performance
Solar energy generation in Plasnica peaks during the summer months, with an impressive output of 7.35 kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season, yielding 5.49 kWh/day. However, autumn and winter see a substantial drop in solar performance, with outputs of 3.30 kWh/day and 2.15 kWh/day, respectively.
This stark contrast between seasons indicates that while Plasnica can be highly productive for solar energy during half of the year, it faces challenges in maintaining consistent output year-round. The summer and spring months present ideal conditions for solar generation, making these seasons particularly suitable for maximizing energy production.
Optimal Panel Installation
To maximize year-round solar energy production in Plasnica, fixed solar panels should be installed at a tilt angle of 35 degrees facing south. This angle has been calculated to optimize the total annual energy yield, taking into account the location's latitude and seasonal sun positions.
Environmental and Weather Considerations
While Plasnica's location is generally favorable for solar energy production, there are some environmental and weather factors that could potentially impact solar panel efficiency:
- Snow accumulation in winter: The region's winter snowfall could temporarily reduce panel output if not addressed.
- Dust and pollen: Seasonal accumulation of dust and pollen might slightly decrease panel efficiency.
To mitigate these issues, consider implementing the following preventative measures:
- Install panels at a steeper angle to promote snow sliding off
- Use self-cleaning panel technologies or schedule regular cleaning
- Implement a monitoring system to quickly identify and address any drops in performance
In conclusion, while Plasnica faces challenges during autumn and winter months, its location still offers significant potential for solar energy generation, especially during spring and summer. With proper installation techniques and maintenance practices, solar PV systems in this area can effectively harness the available solar resources throughout the year.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Plasnica
Seasonal solar PV output for Latitude: 41.4707, Longitude: 21.1152 (Plasnica, 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 Plasnica, North Macedonia
To maximize your solar PV system's energy output in Plasnica, North Macedonia (Lat/Long 41.4707, 21.1152) 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 Plasnica, 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 Plasnica, 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 | 34° 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 Plasnica, 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 Plasnica, 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 Plasnica, North Macedonia
The topography around Plasnica, North Macedonia, is characterized by a diverse landscape of rolling hills, valleys, and mountainous terrain. This small municipality is nestled in the western part of the country, surrounded by the picturesque scenery of the Balkan region. The area features a mix of forested slopes and open grasslands, with elevations ranging from moderate hills to more pronounced mountain ranges in the vicinity. To the west of Plasnica, the terrain becomes increasingly mountainous as it approaches the Bistra mountain range. These mountains, part of the larger Dinaric Alps system, create a rugged backdrop to the region. The eastern side of Plasnica gradually transitions into gentler hills and valleys, offering a more open landscape. The Treska River flows near Plasnica, carving its way through the terrain and creating fertile valleys along its course. This river valley provides some of the flatter areas in the region, contrasting with the surrounding hillsides and mountains.
Potential for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would combine relatively flat or gently sloping terrain with good sun exposure and minimal shading from surrounding mountains. The most promising areas for solar PV development would likely be found in the more open valleys and plateaus to the east and southeast of Plasnica. These areas generally have less extreme topography compared to the mountainous regions to the west, potentially offering larger continuous spaces for solar panel arrays. Specifically, the broader valleys along the Treska River could provide suitable sites for solar farms. These areas benefit from their lower elevation and more open sky view, which is crucial for maximizing solar energy capture. Additionally, any elevated plateaus or wide ridges in the vicinity that are not heavily forested could also be considered, as they might offer good sun exposure throughout the day. However, it's important to note that detailed site surveys would be necessary to determine the most optimal locations. Factors such as local microclimate, existing land use, proximity to power infrastructure, and environmental considerations would all need to be carefully assessed before embarking on any large-scale solar PV project in the region.Citation Guide
