Brest, Belarus, located at coordinates 52.0901° N, 23.6836° E, presents a mixed picture for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.

Seasonal Solar Performance

Solar energy production in Brest varies dramatically across the seasons. Summers are the most productive, with an average daily output of 5.76 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 4.12 kWh/day. Autumn sees a significant drop to 2.23 kWh/day, while winter experiences the lowest output at just 1.02 kWh/day.

The stark contrast between summer and winter production highlights the challenges of relying solely on solar power in this region. The long days and higher sun angle during summer months make it an ideal time for solar energy generation. Conversely, the short days and low sun angle in winter severely limit solar output.

Optimal Panel Installation

To maximize year-round solar production in Brest, fixed solar panels should be installed at a tilt angle of 43 degrees facing south. This angle is calculated to optimize the overall annual energy yield, taking into account the changing sun position throughout the year.

Environmental and Weather Factors

Several factors can impact solar production in Brest. The region experiences significant cloud cover, particularly during autumn and winter months, which can reduce solar irradiance. Snowfall in winter can also temporarily decrease panel efficiency if not promptly removed.

To mitigate these issues, consider installing panels with anti-soiling coatings to reduce snow accumulation. Implementing a regular cleaning schedule, especially after snowfall, can help maintain optimal performance. Additionally, using microinverters or power optimizers can minimize the impact of partial shading on overall system output.

While Brest's location is not ideal for year-round solar production, proper system design and maintenance can still make solar energy a viable component of a diversified energy strategy. The significant seasonal variations suggest that solar power would be most effective when combined with other energy sources to ensure consistent supply throughout 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 4 locations across Belarus. 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 Brest

Seasonal solar PV output for Latitude: 52.0901, Longitude: 23.6836 (Brest, Belarus), 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 43° South in Brest, Belarus

To maximize your solar PV system's energy output in Brest, Belarus (Lat/Long 52.0901, 23.6836) throughout the year, you should tilt your panels at an angle of 43° 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 Brest, Belarus

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 Brest, Belarus. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 43° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
35° South in Summer	54° South in Autumn	65° South in Winter	44° 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 Brest, Belarus

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 Brest, Belarus.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Brest, Belarus

The topography around Brest, Belarus, is characterized by a relatively flat landscape with gentle undulations. This area is part of the vast Eastern European Plain, which extends across much of Belarus and neighboring countries. The terrain near Brest consists primarily of lowlands and small hills, with elevations typically ranging from 130 to 200 meters above sea level. The region surrounding Brest is dotted with numerous rivers and streams, including the notable Bug River, which forms part of the border between Belarus and Poland. These waterways have shaped the landscape over time, creating shallow valleys and occasional floodplains. The area also features scattered forests, agricultural fields, and meadows, contributing to a diverse mix of land cover.

Potential for Solar PV Development

When considering large-scale solar photovoltaic (PV) installations near Brest, several factors come into play. The most suitable areas for such projects would be open, relatively flat lands with good sun exposure. Agricultural fields that are less productive or fallow could be ideal candidates for solar farms, as they often provide the necessary space and minimal shading. Areas to the south and southeast of Brest might be particularly well-suited for solar PV development. These regions tend to have slightly higher elevations and fewer forested areas, potentially offering better solar irradiance and less obstruction from trees. Additionally, lands that are not prone to flooding and have good drainage would be preferable to ensure the longevity and efficiency of solar installations. It's important to note that while the topography around Brest is generally favorable for solar PV, other factors such as grid connectivity, local regulations, and environmental considerations would also play crucial roles in determining the most appropriate locations for large-scale solar projects. Detailed site assessments and feasibility studies would be necessary to identify the optimal areas for such developments in the region.
