Ramadi, Al Anbar, Iraq, located at 33.4202°N, 43.3045°E in the Northern Sub Tropics, presents a promising location for solar PV energy generation. The city experiences significant variations in solar output across different seasons, which affects its overall suitability for year-round solar energy production.
Seasonal Solar Output
Solar energy production in Ramadi fluctuates throughout the year. Summer months yield the highest output at 8.32 kWh per day for each kW of installed solar capacity. Spring follows with 7.03 kWh/day, while autumn sees a decrease to 5.16 kWh/day. Winter experiences the lowest production at 3.75 kWh/day per kW installed. The substantial difference between summer and winter output indicates that Ramadi has a strong seasonal variation in solar potential. This variation is primarily due to changes in day length and sun angle throughout the year.Ideal Generation Periods
The most favorable times for solar energy generation in Ramadi are during summer and spring. These seasons offer longer daylight hours and higher sun angles, resulting in increased solar panel efficiency. Summer, in particular, stands out as the peak period for solar energy production. Autumn and winter, while less productive, still contribute to the overall annual energy output. However, system designers should account for these lower-yield periods when planning year-round energy needs.Optimal Panel Tilt
For fixed-panel installations in Ramadi, Al Anbar, the ideal tilt angle to maximize year-round solar production is 29 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the seasonal variations in sun position.Environmental Factors and Mitigation
Ramadi's location in a desert environment presents some challenges for solar PV installations: 1. Dust and sand accumulation: Regular dust storms can reduce panel efficiency by blocking sunlight. 2. High temperatures: Extreme heat can decrease solar panel performance. To mitigate these issues, consider the following measures:- Install automated cleaning systems or implement regular manual cleaning schedules to remove dust and sand.
- Use solar panels designed for high-temperature environments and ensure proper ventilation behind panels to reduce heat buildup.
- Implement tracking systems to maximize sun exposure and increase overall energy yield.
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 Ramadi
Seasonal solar PV output for Latitude: 33.4202, Longitude: 43.3045 (Ramadi, 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 Ramadi, Iraq
To maximize your solar PV system's energy output in Ramadi, Iraq (Lat/Long 33.4202, 43.3045) 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 Ramadi, 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 Ramadi, 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 Ramadi, 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 Ramadi, Iraq.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Ramadi, Iraq
The topography around Ramadi, Iraq is characterized by relatively flat terrain with some gentle undulations. Ramadi is situated in the heart of the Anbar Province, which is part of the vast Mesopotamian Plain. This region is primarily a desert landscape, with the Euphrates River flowing through it, providing a vital water source in an otherwise arid environment.
The immediate area surrounding Ramadi consists of open, desert-like terrain with sparse vegetation. As you move away from the city, the landscape becomes increasingly barren, with sandy and rocky areas dominating the scenery. The elevation in this region is generally low, typically ranging from about 40 to 60 meters above sea level.
To the west and southwest of Ramadi, the terrain gradually transitions into the Syrian Desert, which extends across the border into Syria. This area is characterized by vast, open spaces with minimal topographic variation, making it potentially suitable for large-scale solar PV installations.
The areas most suited for large-scale solar PV projects near Ramadi would likely be found in the expansive desert regions to the west and southwest of the city. These areas offer several advantages for solar energy development:
- Abundant open space with minimal competing land uses
- Relatively flat terrain, reducing the need for extensive land preparation
- High levels of solar radiation due to the desert climate
- Limited cloud cover throughout the year
- Low population density, minimizing potential conflicts with local communities
However, it's important to note that while these areas may be topographically suitable, other factors such as grid connectivity, access to water for panel cleaning, and security considerations would also need to be taken into account when planning large-scale solar PV installations in this region.
The areas closer to the Euphrates River, while potentially having better access to water and infrastructure, may be less ideal due to higher population density and more valuable agricultural land. Additionally, the river valley may experience more dust and sand storms, which could impact solar panel efficiency.
In conclusion, the vast desert expanses to the west and southwest of Ramadi offer the most promising topography for large-scale solar PV development, provided that other logistical and environmental factors can be adequately addressed.
