The location of Edd, Southern Red Sea Region, Eritrea, situated at 13.9331° N, 41.6935° E, presents a generally favorable environment for solar energy production throughout the year. Located in the tropics, this area experiences consistent sunlight and is characterized more by wet and dry seasons than traditional four-season patterns.

Seasonal Solar Performance

Solar energy generation at this location remains relatively stable across seasons, with a notable peak in spring. The expected daily electricity output per kilowatt of installed solar capacity is as follows:

• Spring: 7.52 kWh/day
• Summer: 6.39 kWh/day
• Autumn: 6.35 kWh/day
• Winter: 6.15 kWh/day

The spring season stands out as the most productive time for solar energy generation in Edd, Southern Red Sea Region, with output significantly higher than other seasons. This peak likely coincides with clearer skies and optimal sun angles during this period.

Optimal Panel Tilt

For fixed solar panel installations in Edd, Southern Red Sea Region, the ideal tilt angle to maximize year-round energy production is 13 degrees facing South. This angle has been calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the location's latitude and the Earth's elliptical orbit.

Environmental Considerations

While Edd's location is generally conducive to solar energy production, there are some environmental factors that could potentially impact solar panel efficiency:

1. Dust and sand: Given Eritrea's arid climate, dust and sand accumulation on solar panels could reduce their efficiency. Regular cleaning and maintenance of the panels is crucial to maintain optimal performance.

2. High temperatures: Extreme heat can slightly decrease solar panel efficiency. Using heat-resistant panels and ensuring proper ventilation during installation can help mitigate this issue.

3. Coastal location: Edd's proximity to the Red Sea may expose solar installations to salt spray, which could corrode equipment over time. Using corrosion-resistant materials and applying protective coatings can help extend the lifespan of solar installations in this coastal environment.

Despite these challenges, with proper planning and maintenance, Edd, Southern Red Sea Region, Eritrea, remains a promising location for solar energy production, offering consistent and substantial energy output throughout the year.

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

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 5 locations across Eritrea. 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 Edd

Seasonal solar PV output for Latitude: 13.9331, Longitude: 41.6935 (Edd, Eritrea), 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 13° South in Edd, Eritrea

To maximize your solar PV system's energy output in Edd, Eritrea (Lat/Long 13.9331, 41.6935) throughout the year, you should tilt your panels at an angle of 13° 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 Edd, Eritrea

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 Edd, Eritrea. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 13° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
2° North in Summer	20° South in Autumn	30° South in Winter	8° 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 Edd, Eritrea

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 Edd, Eritrea.

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 Edd, Eritrea

The topography around Edd, Eritrea, is characterized by a diverse and rugged landscape. Situated along the Red Sea coast, Edd is surrounded by a narrow coastal plain that quickly gives way to steep, mountainous terrain inland. The coastal area is relatively flat and arid, with sandy beaches and salt flats. As one moves away from the coast, the land rises abruptly into the foothills of the Ethiopian Highlands. These highlands form a dramatic backdrop to the coastal region, with steep escarpments and deeply incised valleys. The mountains in this area can reach heights of over 2,000 meters above sea level, creating a stark contrast to the low-lying coastal plain. The terrain is generally rocky and sparsely vegetated, with limited areas of arable land.

Potential for Solar PV Development

When considering areas nearby that would be most suited to large-scale solar PV installations, the coastal plain near Edd offers promising potential. This region benefits from several favorable factors for solar energy production: Firstly, the flat terrain of the coastal plain provides ample space for the installation of solar panels without the need for extensive land preparation. The lack of steep slopes or significant geographical obstacles makes construction and maintenance more straightforward and cost-effective. Secondly, the area experiences high levels of solar radiation throughout the year due to its proximity to the equator and generally clear skies. The arid climate means there is little cloud cover to interfere with solar energy collection, maximizing the potential output of PV installations. Additionally, the sparse vegetation and limited agricultural use of the coastal plain mean that large-scale solar projects would have minimal impact on existing land use or ecosystems. This could potentially reduce environmental concerns and simplify the approval process for such developments. However, it's important to note that the harsh coastal environment, including high temperatures and potential salt spray from the Red Sea, would require careful selection of equipment designed to withstand these conditions. Proper maintenance would also be crucial to ensure the longevity and efficiency of any solar PV installations in this area. While the mountainous regions inland might offer some suitable locations for solar farms on south-facing slopes, the challenging terrain and potential for shading from nearby peaks make the coastal plain a more attractive option for large-scale development. The relatively easy access to the port of Edd could also facilitate the transportation of equipment and materials necessary for constructing and maintaining solar PV installations.
