Solar Energy Potential in Pasiran, West Kalimantan, Indonesia

Pasiran, West Kalimantan, Indonesia, located in the tropics, offers a promising location for solar energy generation with consistent year-round production capabilities. This tropical location experiences minimal seasonal variation in sunlight, with the climate primarily divided between wet and dry seasons rather than the traditional four seasons experienced in temperate regions. The energy production data shows impressive consistency across all meteorological seasons. Spring stands out as the most productive period with an average daily output of 6.20kWh per kilowatt of installed solar capacity. The remaining seasons show remarkably stable production: 5.59kWh/day in summer, 5.50kWh/day in autumn, and 5.39kWh/day in winter.

Optimal Panel Installation

For fixed solar panel installations in Pasiran, West Kalimantan, the ideal tilt angle to maximize year-round energy production is 0 degrees. This flat orientation is optimal due to Pasiran's proximity to the equator (at latitude 0.9143), where the sun passes nearly directly overhead throughout the year. This flat installation simplifies the mounting process and reduces wind load concerns compared to angled installations.

Environmental and Weather Considerations

Despite the excellent solar potential, several environmental factors require consideration when installing solar systems in Pasiran:

• Heavy rainfall during the wet season could temporarily reduce solar output and may necessitate more frequent panel cleaning.
• High humidity levels typical of tropical environments can accelerate corrosion of mounting hardware and electrical components.
• Potential for tropical storms or monsoon conditions could impact system durability.

Preventative Measures

To maximize energy production and system longevity in Pasiran's tropical climate, consider implementing these preventative measures:

• Use marine-grade stainless steel mounting hardware and corrosion-resistant components designed for tropical environments.
• Install an automated cleaning system or establish a regular manual cleaning schedule to remove dust and debris, especially after the dry season when dust accumulation is highest.
• Ensure proper drainage around ground-mounted systems to prevent flooding during heavy rains.
• Select high-temperature rated panels with good performance in hot conditions, as tropical temperatures can affect panel efficiency.

With these considerations addressed, Pasiran represents an excellent location for solar energy generation with its consistent year-round solar resource and minimal seasonal variation in production potential.

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 Pasiran

Seasonal solar PV output for Latitude: 0.9143, Longitude: 108.9677 (Pasiran, 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 0° in Pasiran, Indonesia

To maximize your solar PV system's energy output in Pasiran, Indonesia (Lat/Long 0.9143, 108.9677) throughout the year, you should tilt your panels at an angle of 0° 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 Pasiran, 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 Pasiran, Indonesia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 0° tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
15° North in Summer	7° South in Autumn	16° South in Winter	5° 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 Pasiran, 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 Pasiran, Indonesia.

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 Pasiran, Indonesia

The topography surrounding Pasiran, Indonesia, located at approximately 0.9143° North latitude and 108.9677° East longitude, is characterized by a diverse landscape typical of West Kalimantan province in Borneo. This area features gently rolling terrain with interspersed low hills and shallow valleys. The elevation generally remains modest throughout the region, rarely exceeding 100 meters above sea level in the immediate vicinity of Pasiran. The landscape is predominantly covered by tropical vegetation, with patches of secondary forest interspersed with agricultural land. Much of the natural primary rainforest that once dominated this region has been modified by human activities, including rubber plantations, palm oil cultivation, and subsistence farming. The soil composition tends toward the acidic, with significant clay content typical of tropical regions. Numerous small streams and rivulets crisscross the area, eventually feeding into larger river systems that flow toward the South China Sea. These waterways have shaped the local topography through erosion, creating gentle slopes and occasional broader floodplains. During monsoon seasons, some lower-lying areas may experience temporary inundation.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic development near Pasiran, the most suitable areas would be found on the cleared, elevated terrain that offers good drainage and minimal shading. Several specific topographical features make certain nearby areas particularly advantageous: The gently sloping hillsides facing north or south provide ideal conditions for solar panel placement. These natural inclines, particularly those with 5-15 degree slopes, offer improved solar exposure compared to perfectly flat terrain. Such topography can be found predominantly in the slightly elevated regions approximately 3-5 kilometers east of Pasiran. Areas where agricultural clearing has already occurred present practical opportunities for solar development without requiring additional forest removal. These regions, often characterized by open fields or plantations with sparse tree cover, would minimize environmental impact while offering the necessary space for extensive arrays. The slightly elevated plateaus that exist in patches throughout the region provide natural protection from potential flooding during intense rainfall periods. These areas, typically 20-40 meters above the surrounding landscape, offer better drainage and reduced humidity, potentially extending the operational lifespan of solar equipment. It's worth noting that the extensive river network in the broader region should be considered when planning large installations, as proximity to water bodies can increase ambient humidity and potentially impact equipment performance. The optimal sites would maintain a reasonable buffer distance from major waterways while still allowing access for construction and maintenance. Areas to avoid would include the lower wetland regions that experience seasonal flooding, steep slopes with unstable soil conditions, and any remaining primary forest sections that hold significant ecological value. By focusing development on already-modified landscapes with favorable topographical features, solar projects can balance energy production goals with environmental considerations.
