Qina, Qena, Egypt represents an excellent location for year-round solar photovoltaic energy generation, situated in the Northern Sub Tropics at coordinates 26.1643°N, 32.7242°E. The solar energy output data demonstrates consistently strong performance across all seasons, making this location highly suitable for solar installations.

Seasonal Solar Performance

The solar energy production at Qina shows impressive year-round capabilities. Summer delivers the highest output at 8.62 kWh per day per kW of installed solar capacity, while spring follows closely with 8.17 kWh per day per kW. Even during the lower-production seasons, autumn generates 6.20 kWh per day per kW, and winter still produces a respectable 5.13 kWh per day per kW. The ideal times for solar generation at this location are clearly summer and spring, when output exceeds 8 kWh per day per kW. However, the relatively modest seasonal variation means that solar installations remain productive throughout the entire year, with winter production still reaching about 60% of peak summer levels.

Optimal Panel Configuration

For fixed panel installations at Qina, Qena, the ideal tilt angle is 23 degrees facing south to maximize total year-round solar production. This angle is calculated by analyzing daily solar elevation angles, determining optimal panel positioning, and weighting these factors using solar irradiance data while accounting for Earth's elliptical orbit.

Environmental and Weather Challenges

Several significant environmental factors could impede solar production at this Egyptian location and require careful consideration during installation:

• Desert dust and sand accumulation - The arid climate means frequent dust storms and continuous sand deposition on panels
• Extreme heat - High ambient temperatures can reduce panel efficiency and accelerate equipment degradation
• Sandstorms and abrasive particles - These can physically damage panel surfaces and reduce light transmission
• Low humidity and static electricity - Dry conditions increase dust adhesion to panel surfaces

Preventative Measures for Enhanced Performance

Several installation strategies can help maintain optimal energy production despite these environmental challenges:

• Regular cleaning systems - Install automated cleaning equipment or establish frequent manual cleaning schedules to remove dust and sand buildup
• Enhanced ventilation design - Ensure adequate airflow around panels to reduce operating temperatures and improve efficiency
• Protective coatings - Apply anti-soiling and hydrophobic coatings to panel surfaces to minimize dust adhesion
• Robust mounting systems - Use heavy-duty mounting hardware designed to withstand high winds and sand abrasion
• Proper spacing - Install panels with sufficient spacing to promote air circulation and facilitate cleaning access

Despite these environmental challenges, Qina's consistently high solar irradiance levels make it an ideal location for solar energy generation when proper installation and maintenance practices are implemented.

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

Seasonal solar PV output for Latitude: 26.1643, Longitude: 32.7242 (Qina, Egypt), 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 23° South in Qina, Egypt

To maximize your solar PV system's energy output in Qina, Egypt (Lat/Long 26.1643, 32.7242) throughout the year, you should tilt your panels at an angle of 23° 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 Qina, Egypt

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 Qina, Egypt. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 23° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
10° South in Summer	31° South in Autumn	41° South in Winter	19° 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 Qina, Egypt

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 Qina, Egypt.

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 Qina, Egypt

Topographical Features of Qina Region

Qina sits in the heart of Upper Egypt along the eastern bank of the Nile River, positioned within the narrow fertile valley that cuts through the surrounding desert landscape. The city lies at approximately 70 meters above sea level, nestled between the life-giving waters of the Nile to the west and the gradually rising terrain of the Eastern Desert to the east. This location places Qina in one of the most geographically distinctive regions of Egypt, where the lush green agricultural strip of the Nile Valley contrasts sharply with the arid desert expanses on either side.

The immediate vicinity of Qina is characterized by relatively flat to gently undulating terrain, typical of the Nile Valley floor. The western side of the city extends toward the river, where fertile alluvial soils support intensive agriculture. Moving eastward from the city center, the landscape begins a gradual ascent toward the Eastern Desert plateau, with the terrain becoming increasingly rocky and barren as it moves away from the river's influence.

The Eastern Desert, which dominates the landscape east of Qina, presents a complex topography of limestone plateaus, sandstone formations, and scattered wadis (dry riverbeds). These elevated areas rise progressively from the Nile Valley, eventually reaching heights of several hundred meters above sea level. The desert terrain is marked by exposed bedrock, gravel plains, and occasional rocky outcrops, creating a landscape that receives minimal precipitation and supports little vegetation.

Optimal Areas for Large-Scale Solar Development

The most promising locations for extensive solar photovoltaic installations lie in the Eastern Desert areas surrounding Qina, particularly on the elevated plateaus and flat desert plains that extend eastward from the city. These desert regions offer several key advantages for solar development, including vast expanses of relatively level terrain that require minimal grading and preparation work.

The limestone and sandstone plateaus located 10 to 30 kilometers east of Qina present ideal conditions for large solar farms. These elevated areas feature stable geological foundations with minimal risk of flooding, while their distance from agricultural zones eliminates conflicts with food production. The terrain in these locations is generally firm and well-drained, reducing construction challenges and long-term maintenance concerns associated with unstable ground conditions.

Areas of particular interest include the desert plains northeast and southeast of Qina, where the topography transitions from the gentle slopes near the Nile Valley to the more stable plateau regions. These transitional zones often provide the best combination of accessibility for construction and maintenance while offering the flat, unobstructed terrain essential for optimal solar panel positioning and minimal shading between panel arrays.

The regions further east, while offering excellent solar conditions, become increasingly challenging for development due to more rugged terrain and greater distances from existing infrastructure. However, the intermediate desert areas, roughly 15 to 25 kilometers from Qina, strike an optimal balance between suitable topography and practical accessibility for large-scale solar installations.

Transportation access represents another crucial factor, with areas near existing desert roads or those suitable for new road construction being particularly attractive for development. The relatively stable desert surface in many locations east of Qina can support heavy construction equipment and ongoing maintenance operations without the complications that might arise in areas with loose sand or extremely rocky terrain.
