Muhafazat al Qadisiyah, Iraq, situated in the Northern Sub Tropics, presents a promising location for solar PV energy generation. This area, with coordinates 31.9167, 45.0833, experiences varying levels of solar energy production throughout the year.

Seasonal Solar Energy Production

The region sees significant fluctuations in solar energy output across the seasons. Summer stands out as the most productive period, with an impressive 8.22 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, yielding 7.08 kWh/day. Autumn sees a moderate decrease to 5.26 kWh/day, while winter experiences the lowest output at 3.81 kWh/day.

Optimal Times for Solar Generation

The most ideal times for solar energy production in Muhafazat al Qadisiyah are during the summer months, typically from June to August, followed closely by the spring season from March to May. These periods offer extended daylight hours and generally clearer skies, maximizing solar panel efficiency.

Panel Tilt Angle for Maximum Efficiency

For fixed panel installations in this location, the optimal tilt angle to maximize year-round solar production is 28 degrees facing South. This angle has been calculated to capture the most sunlight throughout the year, taking into account the Earth's elliptical orbit and the location's specific latitude.

Environmental Factors and Mitigation Strategies

While Muhafazat al Qadisiyah is generally favorable for solar energy production, there are some environmental factors to consider:

• Dust and sand: The region's arid climate can lead to dust accumulation on solar panels, reducing their efficiency. Regular cleaning and maintenance of panels is crucial.
• High temperatures: Extreme heat can slightly decrease panel efficiency. Using heat-resistant panels and ensuring proper ventilation can help mitigate this issue.

To combat these challenges, consider implementing automated cleaning systems, using anti-soiling coatings on panels, and ensuring proper panel spacing for adequate airflow. Additionally, selecting high-quality, heat-resistant solar panels can help maintain efficiency even during the hottest months.

Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 36 locations across Iraq. 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 Muhafazat Al Qadisiyah

Seasonal solar PV output for Latitude: 31.9167, Longitude: 45.0833 (Muhafazat Al Qadisiyah, Iraq), 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 28° South in Muhafazat Al Qadisiyah, Iraq

To maximize your solar PV system's energy output in Muhafazat Al Qadisiyah, Iraq (Lat/Long 31.9167, 45.0833) throughout the year, you should tilt your panels at an angle of 28° 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 Muhafazat Al Qadisiyah, Iraq

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 Muhafazat Al Qadisiyah, Iraq. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 28° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
16° South in Summer	36° South in Autumn	47° South in Winter	25° 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 Muhafazat Al Qadisiyah, Iraq

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 Muhafazat Al Qadisiyah, Iraq.

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 Muhafazat Al Qadisiyah, Iraq

The topography around Muhafazat al Qadisiyah, Iraq, is characterized by a predominantly flat and arid landscape. This region, located in the southeastern part of the country, is part of the Mesopotamian Plain, which is known for its low-lying terrain and expansive desert areas. The land is generally featureless, with occasional gentle undulations and scattered small hills. The area is dominated by the Euphrates River, which flows through the region, creating a narrow strip of fertile land along its banks. This riverine zone contrasts sharply with the surrounding desert environment. Away from the river, the terrain transitions into a vast expanse of desert, featuring sandy and gravelly surfaces interspersed with areas of hard-packed earth.

Solar PV Potential

The topographical characteristics of Muhafazat al Qadisiyah make it highly suitable for large-scale solar photovoltaic (PV) installations. The flat, open terrain provides ideal conditions for the deployment of extensive solar panel arrays. The absence of significant natural obstacles, such as mountains or dense forests, ensures minimal shading and maximum exposure to sunlight throughout the day. Areas most suited for large-scale solar PV projects would be the desert regions away from the Euphrates River. These locations offer several advantages: Firstly, the abundance of unused land in the desert provides ample space for expansive solar farms without interfering with agricultural activities or urban development. The flat terrain also simplifies construction and reduces the costs associated with land preparation. Secondly, the desert climate in this region is characterized by high levels of solar radiation and numerous clear, sunny days throughout the year. This consistent exposure to intense sunlight maximizes the potential energy generation from solar panels. Lastly, the dry, dust-free atmosphere in the desert areas contributes to the efficiency of solar panels by minimizing the accumulation of particulates on their surfaces, which can reduce their effectiveness. While the entire region shows promise for solar energy development, it's important to consider factors such as proximity to existing power infrastructure and accessibility for construction and maintenance when selecting specific sites for large-scale solar PV installations.
