Qaryat ad Duhnah, Iraq, located at 33.3169°N, 44.2336°E, presents a promising location for solar PV energy generation throughout the year. This site in the Northern Sub Tropics experiences significant seasonal variations in solar energy production, which is typical for its latitude.

Seasonal Solar Performance

The location demonstrates strong solar potential, particularly during the summer months. In summer, each kilowatt of installed solar capacity can generate an impressive 8.32 kWh per day. Spring follows as the second-most productive season, with 6.98 kWh/day per kW installed. Autumn sees a moderate decrease in production, yielding 5.22 kWh/day per kW. Winter, as expected, shows the lowest output at 3.69 kWh/day per kW, but still maintains a respectable level of energy generation.

Optimal Panel Positioning

To maximize year-round solar energy production at this location, fixed solar panels should be tilted at an angle of 29 degrees facing South. This optimal angle takes into account the site's latitude and seasonal variations in the sun's position, ensuring the best possible energy capture throughout the year.

Environmental Considerations

While Qaryat ad Duhnah offers favorable conditions for solar energy production, there are some environmental factors to consider: 1. Dust and sandstorms: The region's arid climate can lead to dust accumulation on solar panels, potentially reducing their efficiency. Regular cleaning and maintenance of panels is crucial to maintain optimal performance. 2. High temperatures: Extreme heat during summer months can slightly decrease solar panel efficiency. Using heat-resistant panels and ensuring proper ventilation during installation can help mitigate this issue. To address these challenges, implementing dust-resistant coatings on panels and installing automated cleaning systems can significantly improve energy production. Additionally, choosing high-quality, temperature-tolerant solar panels and incorporating adequate spacing between panel rows for airflow can help maintain efficiency in hot conditions. Overall, Qaryat ad Duhnah presents an ideal location for solar PV energy generation, with strong potential throughout the year and particularly excellent performance during summer and spring 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 Qaryat Ad Duhnah

Seasonal solar PV output for Latitude: 33.3169, Longitude: 44.2336 (Qaryat Ad Duhnah, 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 29° South in Qaryat Ad Duhnah, Iraq

To maximize your solar PV system's energy output in Qaryat Ad Duhnah, Iraq (Lat/Long 33.3169, 44.2336) throughout the year, you should tilt your panels at an angle of 29° 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 Qaryat Ad Duhnah, 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 Qaryat Ad Duhnah, Iraq. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 29° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
17° South in Summer	38° South in Autumn	48° South in Winter	26° 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 Qaryat Ad Duhnah, 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 Qaryat Ad Duhnah, 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 Qaryat Ad Duhnah, Iraq

The area around Qaryat ad Duhnah, Iraq, is characterized by relatively flat terrain typical of the Mesopotamian Plain. This region is part of the larger Tigris-Euphrates river system, which has shaped the landscape over millennia. The topography is generally low-lying, with minimal elevation changes across the area.

The land surrounding Qaryat ad Duhnah is mostly comprised of arid or semi-arid desert, with sparse vegetation. The soil is often sandy or silty, a result of long-term deposition from the rivers. While there may be some gentle undulations in the terrain, there are no significant hills or mountains in the immediate vicinity.

Regarding areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors come into play. The flat, open terrain in this region is generally favorable for solar energy projects. Areas to the south and west of Qaryat ad Duhnah would likely be most suitable, as they tend to have fewer obstructions and potentially less agricultural activity.

Ideal locations for solar PV would be:

1. Open desert areas with minimal vegetation, reducing the need for land clearing.
2. Regions with good road access for construction and maintenance purposes.
3. Areas away from major population centers to minimize land-use conflicts.
4. Locations near existing electrical infrastructure to facilitate grid connection.

It's worth noting that while the topography is suitable, other factors such as dust storms, which are common in this region, could impact solar panel efficiency. Any large-scale solar project would need to incorporate dust-mitigation strategies in its design and maintenance plans.

Before any specific site selection, a detailed environmental and social impact assessment would be necessary to ensure the project's sustainability and minimize any potential negative effects on local communities or ecosystems.
