Erigavo, Sanaag, Somalia, located at 10.6212° N, 47.3667° E, presents a favorable environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than significant temperature variations.

Solar Energy Potential

The solar energy potential in Erigavo is remarkably stable across all seasons, with only slight variations in daily electricity output per kilowatt of installed solar capacity:

• Spring: 7.76 kWh/day
• Winter: 7.22 kWh/day
• Autumn: 7.14 kWh/day
• Summer: 7.06 kWh/day

These figures indicate that Erigavo is an excellent location for year-round solar energy production, with spring being the most productive season. The minimal variation between seasons ensures a reliable and consistent energy supply throughout the year.

Optimal Panel Placement

For fixed solar panel installations in Erigavo, Sanaag, the ideal tilt angle to maximize year-round production is 10 degrees facing South. This angle takes into account the location's latitude and the Earth's elliptical orbit, optimizing the panels' exposure to sunlight throughout the year.

Environmental Considerations

While Erigavo's climate is generally favorable for solar energy production, there are a few environmental factors to consider. The region can experience occasional dust storms, which may temporarily reduce panel efficiency. To mitigate this issue, regular cleaning and maintenance of the solar panels is essential. Additionally, installing panels at a slight angle (as recommended) can help prevent dust accumulation.

Another consideration is the potential for high temperatures during peak summer months. Although modern solar panels are designed to withstand heat, extreme temperatures can slightly reduce efficiency. Ensuring proper ventilation behind the panels and using heat-resistant materials in the installation can help maintain optimal performance.

Overall, Erigavo's location presents an ideal setting for solar energy production, with consistent year-round output and minimal seasonal variations. With proper installation and maintenance, solar PV systems in this area can provide a reliable and sustainable source of electricity.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

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

Seasonal solar PV output for Latitude: 10.6212, Longitude: 47.3667 (Erigavo, Somalia), 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 10° South in Erigavo, Somalia

To maximize your solar PV system's energy output in Erigavo, Somalia (Lat/Long 10.6212, 47.3667) throughout the year, you should tilt your panels at an angle of 10° 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 Erigavo, Somalia

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 Erigavo, Somalia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 10° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
5° North in Summer	17° South in Autumn	26° South in Winter	4° 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 Erigavo, Somalia

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 Erigavo, Somalia.

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 Erigavo, Somalia

The topography around Erigavo, Somalia, is characterized by diverse and rugged terrain. Located in the northern part of the country, Erigavo sits within the Sanaag region, which is part of the larger Somaliland area. The landscape surrounding this city is a mix of mountainous regions, plateaus, and arid plains. To the north of Erigavo, the terrain rises dramatically into the Cal Madow mountain range. These mountains feature steep cliffs and deep valleys, with some peaks reaching heights of over 2,000 meters above sea level. The Cal Madow range runs parallel to the Gulf of Aden coast, creating a natural barrier between the coastal areas and the inland regions. Moving south from Erigavo, the landscape gradually transitions into a high plateau known as the Ogo. This plateau extends for hundreds of kilometers, characterized by gently rolling hills and scattered vegetation. The elevation of the Ogo plateau typically ranges from 900 to 1,500 meters above sea level, providing a stark contrast to the mountainous terrain in the north. To the east and west of Erigavo, the topography is a mixture of rocky outcrops, dry riverbeds (wadis), and expansive arid plains. These areas experience a hot and dry climate, with limited rainfall throughout the year.

Suitable Areas for Large-scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Erigavo, the most suitable areas would likely be found on the Ogo plateau to the south of the city. This region offers several advantages for solar energy development: Firstly, the relatively flat terrain of the plateau provides ample space for the installation of solar panels without the need for extensive land modification. The gently rolling hills can actually be beneficial, as they allow for optimal panel orientation to maximize sun exposure throughout the day. Secondly, the high elevation of the Ogo plateau (900-1,500 meters) means clearer skies and less atmospheric interference, which can improve the efficiency of solar panels. The arid climate of the region also contributes to high levels of solar radiation, making it ideal for solar energy production. Additionally, the sparsely populated nature of the plateau region means that large-scale solar installations would have minimal impact on human settlements and agricultural activities. This could potentially reduce conflicts over land use and simplify the process of acquiring suitable sites for solar farms. However, it's important to note that the development of large-scale solar PV in this region would face challenges, including the need for significant infrastructure investment, particularly in terms of power transmission and road access. The remote location and security concerns in the region would also need to be carefully considered in any solar energy development plans.
