Aden, Yemen, situated at latitude 12.7822 and longitude 45.0436, presents a highly favorable location for solar energy generation throughout the year. This tropical city benefits from consistent sunlight, making it an excellent candidate for solar photovoltaic (PV) installations.

Seasonal Solar Performance

The solar energy output in Aden remains relatively stable across all seasons, with only minor fluctuations. Spring stands out as the most productive period, generating an impressive 7.39 kWh per day for each kilowatt of installed solar capacity. Summer and autumn follow closely, with 6.60 kWh/day and 6.63 kWh/day, respectively. Even during winter, the least productive season, the output remains strong at 6.34 kWh/day. This consistency in solar production throughout the year is a significant advantage for Aden. It ensures a reliable and steady energy supply, reducing the need for alternative power sources during less productive periods.

Optimal Panel Tilt

For fixed solar panel installations in Aden, the ideal tilt angle to maximize year-round energy production is 12 degrees facing South. This angle takes into account the city's latitude and the sun's position throughout the year, ensuring optimal exposure to sunlight and maximizing energy capture.

Environmental Considerations

While Aden's climate is generally conducive to solar energy production, there are a few environmental factors to consider: 1. Dust and sand: Aden's arid climate can lead to dust accumulation on solar panels, potentially reducing their efficiency. Regular cleaning and maintenance of the panels are essential to mitigate this issue. 2. High temperatures: The intense heat in Aden may slightly decrease solar panel efficiency. Choosing heat-resistant panels and ensuring proper ventilation during installation can help maintain optimal performance. To address these challenges, implementing dust-resistant coatings on solar panels and installing automated cleaning systems can significantly improve energy production. Additionally, using panels with high temperature coefficients and ensuring adequate airflow around the installation can help mitigate the effects of extreme heat. In conclusion, Aden's location offers exceptional potential for solar energy generation throughout the year. With proper planning and maintenance, solar PV installations in this area can provide a reliable and sustainable source of clean energy.

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 Aden

Seasonal solar PV output for Latitude: 12.7822, Longitude: 45.0436 (Aden, Yemen), 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 12° South in Aden, Yemen

To maximize your solar PV system's energy output in Aden, Yemen (Lat/Long 12.7822, 45.0436) throughout the year, you should tilt your panels at an angle of 12° 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 Aden, Yemen

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 Aden, Yemen. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 12° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
3° North in Summer	19° South in Autumn	28° South in Winter	6° 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 Aden, Yemen

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 Aden, Yemen.

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 Aden, Yemen

Aden, Yemen, situated at the southern tip of the Arabian Peninsula, boasts a diverse and rugged topography that reflects its unique geological history. The city itself is nestled between the sea and a series of extinct volcanoes, creating a dramatic landscape that has shaped human settlement in the region for centuries. The most prominent feature of Aden's topography is the Jebel Shamsan, a horseshoe-shaped volcanic crater that forms a natural harbor known as the Port of Aden. This crater rises steeply from the coastal plain, reaching heights of up to 500 meters above sea level. The rocky slopes of Jebel Shamsan are largely barren, with sparse vegetation clinging to its crevices and gullies. To the north and east of Aden, the terrain gradually transitions into a coastal plain that extends inland. This flat to gently rolling landscape is characterized by sandy and gravelly soils, interspersed with occasional rocky outcrops. As one moves further inland, the terrain becomes increasingly arid and desert-like, with vast expanses of sand dunes and rocky plateaus dominating the landscape.

Potential for Large-Scale Solar PV

When considering areas suitable for large-scale solar photovoltaic (PV) installations near Aden, several factors come into play. The ideal location would offer ample flat or gently sloping land, minimal vegetation, good road access, and proximity to existing power infrastructure. The coastal plain to the north and east of Aden presents the most promising opportunities for solar PV development. This area offers expansive, relatively flat terrain that would require minimal site preparation. The arid climate and lack of dense vegetation further enhance its suitability, as there would be little need for land clearing or ongoing maintenance to prevent shading of solar panels. Specific locations that might be particularly well-suited for solar PV installations include the areas around the towns of Al Buraiqeh and Dar Saad, located approximately 10-20 kilometers north of Aden. These areas offer a good balance of flat terrain, existing infrastructure, and proximity to population centers that could benefit from the generated electricity. It's worth noting that while the mountainous areas surrounding Aden might seem appealing due to their elevation, the steep and uneven terrain would make large-scale solar installations challenging and costly. Additionally, the potential for shading from nearby peaks could reduce the overall efficiency of solar panels in these areas. In conclusion, the diverse topography around Aden presents both challenges and opportunities for solar PV development. While the mountainous regions may be less suitable, the expansive coastal plains to the north and east offer promising potential for large-scale solar energy projects that could help meet the region's growing energy needs.
