Kampraeus, Tboung Khmum, Cambodia offers good conditions for year-round solar energy generation, with consistent electricity output throughout all seasons. Located in the tropical zone at coordinates 12.0947°N, 105.9502°E, this area benefits from relatively stable solar production that varies moderately between seasons.
Seasonal Solar Performance
The solar energy output at Kampraeus shows favorable generation potential across all four meteorological seasons. Spring delivers the highest production at 6.15 kWh per day per kW of installed solar capacity, followed closely by summer at 6.11 kWh per day. Winter maintains solid performance at 5.70 kWh per day, while autumn shows the lowest output at 5.07 kWh per day per kW installed. For optimal year-round performance, solar panels should be installed at a fixed tilt angle of 11 degrees facing south. This angle maximizes total annual energy production by accounting for the sun's varying position throughout the year and weighting the optimal daily angles by solar irradiance data.Environmental and Weather Challenges
Several local factors in Kampraeus could significantly impact solar panel performance and require careful consideration during installation planning. The tropical climate brings intense monsoon seasons with heavy rainfall, high humidity, and potential flooding. These conditions can reduce solar output through cloud cover and may damage equipment if proper drainage and waterproofing measures aren't implemented. Additionally, the high humidity environment accelerates corrosion of metal components and electrical connections. Dust accumulation presents another challenge, particularly during dry seasons when fine particles settle on panel surfaces and reduce light transmission. The tropical environment also supports rapid vegetation growth, which can create shading issues if not properly managed through regular maintenance.Preventative Installation Measures
To maximize energy production despite these challenges, several installation strategies should be employed:- Install panels with adequate ground clearance and proper drainage systems to prevent flood damage
- Use marine-grade or tropical-rated electrical components and connections to resist humidity and corrosion
- Apply anti-corrosion coatings to mounting hardware and regularly inspect all metal components
- Design cleaning access and implement regular panel washing schedules to remove dust buildup
- Maintain clear vegetation zones around installations and conduct periodic trimming of nearby plants
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 Kampraeus
Seasonal solar PV output for Latitude: 12.0947, Longitude: 105.9502 (Kampraeus, Cambodia), 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 11° South in Kampraeus, Cambodia
To maximize your solar PV system's energy output in Kampraeus, Cambodia (Lat/Long 12.0947, 105.9502) throughout the year, you should tilt your panels at an angle of 11° 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 Kampraeus, Cambodia
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 Kampraeus, Cambodia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 11° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 4° North in Summer | 18° 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 Kampraeus, Cambodia
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 Kampraeus, Cambodia.
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 Kampraeus, Cambodia
Topographical Features Around Kampraeus
The terrain surrounding Kampraeus in Cambodia is characterized by relatively flat to gently rolling lowlands that form part of the expansive Mekong River basin. This region sits within the broader Cambodian plain, where elevations typically remain modest and the landscape exhibits minimal dramatic elevation changes. The area benefits from well-drained soils and gentle gradients that have historically supported agricultural activities. Local topography includes scattered low hills and undulating countryside interspersed with flat agricultural plains. The drainage patterns in this region flow generally toward the Mekong River system, creating natural depressions and slightly elevated areas that provide subtle variation in the otherwise relatively uniform landscape. Small waterways and seasonal streams traverse the area, contributing to the gentle contours of the land.Vegetation and Land Use Patterns
The surrounding landscape predominantly features agricultural land use, with rice paddies, crop fields, and rural settlements distributed across the terrain. Areas of secondary forest growth and scattered tree cover exist alongside cleared agricultural zones. The vegetation patterns reflect both natural drainage characteristics and human modification of the landscape over generations of farming activity. Rural roads and pathways connect small communities throughout the region, following the natural contours of the land and avoiding areas prone to seasonal flooding. The existing infrastructure demonstrates how local topography influences settlement patterns and transportation networks.Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations would be the elevated, well-drained areas that remain above seasonal flood levels while maintaining relatively flat profiles. These slightly elevated plains offer stable ground conditions and minimal shading from topographical features, making them ideal for solar array deployment. Areas with gentle south-facing slopes would provide particularly favorable conditions, as these orientations maximize solar exposure throughout the day. The rolling countryside northeast and southwest of Kampraeus contains several such locations where the terrain rises gradually from surrounding lowlands while maintaining accessibility for construction and maintenance activities. Former agricultural areas on stable, elevated ground present excellent opportunities for solar development, particularly where the soil conditions provide good drainage and the topography allows for efficient panel arrangement. These locations typically feature minimal tree cover and existing access routes that could support large-scale infrastructure development. The key consideration for site selection involves avoiding low-lying areas subject to seasonal water accumulation while identifying zones with sufficient flat or gently sloping terrain to accommodate extensive solar arrays. The natural drainage patterns help identify these optimal elevated areas that remain dry year-round while offering the expansive, unobstructed terrain necessary for utility-scale solar installations.Cambodia solar PV Stats as a country
