Solar Energy Potential at Duri Pulo, Indonesia
Duri Pulo, Indonesia offers a promising location for solar PV installations with consistent energy production throughout the year. This tropical location experiences relatively stable solar radiation patterns, making it suitable for year-round solar energy generation. The seasonal electricity output shows impressive consistency across the year. During spring, panels can generate approximately 5.42 kWh per day for each kilowatt installed, making it the most productive season. Autumn follows closely with 5.35 kWh/day, while winter produces 5.04 kWh/day. Summer shows the lowest output at 4.71 kWh/day per kilowatt of installed capacity, though the difference between seasons remains relatively small compared to locations at higher latitudes.Optimal Panel Installation
For fixed solar panel installations in Duri Pulo, the ideal tilt angle to maximize year-round energy production is 7 degrees facing North. This specific angle has been calculated based on the location's position relative to the sun's path throughout the year, taking into account the weighted solar potential at this tropical latitude.Environmental and Weather Considerations
Several environmental factors could potentially impact solar production in Duri Pulo:- Heavy rainfall during the wet season can reduce solar efficiency by limiting direct sunlight exposure. Installing panels with adequate drainage and water-resistant components is essential.
- High humidity levels may accelerate corrosion of mounting hardware and electrical connections, requiring marine-grade materials and proper sealing.
- Urban air pollution in Jakarta can deposit particulate matter on panels, reducing efficiency. Regular cleaning schedules and possibly automated cleaning systems should be considered.
- Tropical storms, while less frequent than in some other regions, can damage installations if not properly secured. Reinforced mounting systems designed for high wind conditions are recommended.
Preventative Measures
To maximize energy production despite these challenges, consider implementing elevated mounting systems to improve airflow and reduce humidity-related issues. Anti-soiling coatings can help panels maintain efficiency between cleanings by preventing dust and pollution buildup. Additionally, installing micro-inverters or power optimizers rather than string inverters can minimize production losses when partial shading occurs during cloudy periods of the wet season. The minimal seasonal variation makes Duri Pulo particularly suitable for consistent energy planning throughout the year, with only minor adjustments needed between the most productive spring months and slightly less productive summer period.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 Duri Pulo
Seasonal solar PV output for Latitude: -6.1681, Longitude: 106.8018 (Duri Pulo, Indonesia), 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 7° North in Duri Pulo, Indonesia
To maximize your solar PV system's energy output in Duri Pulo, Indonesia (Lat/Long -6.1681, 106.8018) throughout the year, you should tilt your panels at an angle of 7° North 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 Duri Pulo, Indonesia
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 Duri Pulo, Indonesia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° North 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 | 12° North in Autumn | 22° North in Winter | 1° North 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 Duri Pulo, Indonesia
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 Duri Pulo, Indonesia.
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 Duri Pulo, Indonesia
The terrain around Duri Pulo, located in Jakarta, Indonesia, is predominantly flat with very minimal elevation changes. This area sits on the coastal plain of Jakarta, which forms part of the larger northern Java coastal lowlands. The elevation typically ranges between 2 to 8 meters above sea level throughout this region, creating a generally level landscape with no significant hills or valleys. Duri Pulo is situated within the densely urbanized area of Jakarta, Indonesia's capital city. The topography has been extensively modified by human development, with natural landforms largely replaced by urban infrastructure including buildings, roads, and other constructed surfaces. The original landscape would have featured alluvial plains formed by sediment deposits from rivers flowing northward from the volcanic highlands of southern Java toward the Java Sea.
Hydrological Features
Several waterways influence the local topography, including canals and the Ciliwung River which runs through Jakarta. These water features have historically shaped the landscape through sediment deposition and occasional flooding. The proximity to the Java Sea to the north also means that much of this region, including Duri Pulo, has a high water table and is susceptible to subsidence issues.Regional Context
Moving south from Duri Pulo, the land gradually increases in elevation toward the volcanic highlands of Java. These highlands, located approximately 50-60 kilometers south, feature more varied topography with hills, valleys, and eventually mountains. The transition from the flat coastal plain to these highlands is gradual, with gentle increases in elevation over many kilometers.Suitable Areas for Solar PV Development
For large-scale solar photovoltaic installations, the immediate urban area around Duri Pulo presents significant constraints due to the dense development and limited available land. However, several areas within reasonable proximity show promise for solar development: The flat, open areas in the regions of Bekasi and Karawang to the east of Jakarta offer more suitable conditions for large-scale solar installations. These areas combine favorable flat topography with larger tracts of available land compared to the urban core. Areas north of Jakarta along the coast, particularly in less developed sections, provide flat terrain with good solar exposure. However, these locations must be evaluated carefully for flood risk and land subsidence concerns. The gradually rising terrain south of Jakarta, particularly in parts of West Java province around Bogor and Depok, offers some potential for solar development on land that is less prone to flooding than the coastal areas. While these areas have slightly more varied topography, they still contain extensive flat or gently sloping sections suitable for solar arrays. The most promising locations combine several key topographical advantages: relatively flat terrain to minimize construction costs, elevation sufficient to reduce flood risks, stable geological conditions to prevent subsidence issues, and adequate distance from major urban shadows or obstructions that could reduce solar efficiency. When considering large-scale solar development in this region, it's important to note that while the flat topography is generally favorable for construction, other factors such as land availability, grid connectivity, and environmental considerations will likely be more limiting than the physical landscape itself.Indonesia solar PV Stats as a country
