The location at Lom, Montana, Bulgaria, situated at 43.8134°N, 23.2314°E, presents a mixed scenario for solar PV energy generation throughout the year. This Northern Temperate Zone location experiences significant seasonal variations in solar energy production, which impacts its overall suitability for year-round solar power generation.

Seasonal Solar Performance

Solar energy production at this location peaks during the summer months, with an impressive output of 7.27 kWh per day for each kW of installed solar capacity. Spring follows as the second-most productive season, generating 5.23 kWh/day. However, autumn and winter see a substantial drop in energy production, with 3.11 kWh/day and 1.89 kWh/day respectively.

The stark contrast between summer and winter production highlights the challenges of relying solely on solar power throughout the year in Lom. While the location is excellent for solar energy generation during the warmer months, the significant decrease in output during colder seasons may necessitate alternative energy sources or energy storage solutions to maintain consistent power supply.

Optimal Panel Installation

To maximize year-round solar energy production at this location, fixed solar panels should be installed at a tilt angle of 37 degrees facing south. This optimal angle helps balance energy capture across seasons, ensuring the best possible performance given the location's latitude and seasonal sun angles.

Environmental and Weather Considerations

While Lom'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 during winter months may temporarily reduce panel output
• Dust and pollen from nearby agricultural activities could decrease panel efficiency if not regularly cleaned

To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding off, and implement a regular cleaning schedule, especially during pollen season. Additionally, investing in high-quality, durable panels that can withstand local weather conditions is advisable.

In conclusion, while Lom, Montana, Bulgaria offers excellent solar energy potential during summer and spring, the significant drop in production during autumn and winter presents challenges. Careful planning, optimal panel positioning, and consideration of supplementary energy sources can help maximize the benefits of solar PV installation at this location.

Solar output per kW of installed solar PV by season in Lom

Seasonal solar PV output for Latitude: 43.8134, Longitude: 23.2314 (Lom, Bulgaria), 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 37° South in Lom, Bulgaria

To maximize your solar PV system's energy output in Lom, Bulgaria (Lat/Long 43.8134, 23.2314) throughout the year, you should tilt your panels at an angle of 37° 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 Lom, Bulgaria

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 Lom, Bulgaria. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
28° South in Summer	47° South in Autumn	58° South in Winter	36° 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 Lom, Bulgaria

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 Lom, Bulgaria.

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 Lom, Bulgaria

The area surrounding Lom, Bulgaria, located at coordinates 43.8134°N, 23.2314°E, is characterized by a diverse and interesting topography. Situated on the southern bank of the Danube River, Lom is part of the vast Danubian Plain that stretches across northern Bulgaria. This region is primarily flat to gently rolling, with occasional low hills and shallow valleys interspersed throughout the landscape. To the south of Lom, the terrain gradually becomes more undulating as it transitions into the foothills of the Balkan Mountains. These foothills, while not particularly steep or high, provide a subtle contrast to the flatter areas near the Danube. The land is crisscrossed by small rivers and streams that flow northward, eventually joining the Danube. The soil in this region is generally fertile, consisting of loess deposits and alluvial sediments from the Danube and its tributaries. This has made the area around Lom suitable for agriculture, with many fields and pastures dotting the landscape.

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 relatively flat terrain of the Danubian Plain offers numerous advantages for solar energy development. The areas to the south and southeast of Lom are particularly promising for solar PV projects. These regions benefit from slightly elevated terrain, which can help minimize shading issues and maximize exposure to sunlight. The gently rolling hills in this direction provide ample space for large arrays of solar panels without significant topographical obstacles. Additionally, the agricultural lands surrounding Lom could potentially be repurposed or shared for solar energy production. Many of these fields are already clear of trees and other obstructions, making them ideal candidates for solar farms. The good road infrastructure in the region would also facilitate the construction and maintenance of such facilities. It's worth noting that while the immediate vicinity of the Danube River might seem attractive due to its flatness, these areas may be prone to flooding or have higher humidity levels, which could be less ideal for solar PV installations. Therefore, the slightly more elevated areas further from the river would likely be more suitable for large-scale solar projects. Overall, the topography around Lom offers several promising locations for solar energy development, with the areas south and southeast of the town being particularly well-suited due to their favorable terrain and good solar exposure.

Bulgaria solar PV Stats as a country
