Banjar Pacung, Bali, Indonesia presents an excellent location for year-round solar photovoltaic energy generation. This tropical location benefits from consistent sunlight throughout the year, with energy production varying between seasons based on the region's characteristic wet and dry patterns rather than traditional temperature-based seasons.

Solar Energy Production Performance

The solar energy output at this location demonstrates strong and consistent performance across all seasons. Spring emerges as the most productive period, generating 6.29kWh per day for each kilowatt of installed solar capacity. Autumn follows closely with 6.12kWh/day per kW, making these two seasons the optimal times for solar energy generation at Banjar Pacung. Winter production remains robust at 5.83kWh/day per kW, while summer shows the lowest output at 5.48kWh/day per kW. Even during the least productive season, the generation levels remain quite favorable for solar installation viability.

Optimal Panel Configuration

For fixed panel installations at Banjar Pacung, Bali, the ideal tilt angle to maximize total year-round solar production is 9 degrees facing North. This relatively shallow angle reflects the location's proximity to the equator and helps optimize energy capture throughout the annual solar cycle.

Environmental and Weather Challenges

Several local factors could potentially impact solar production efficiency at this Indonesian location:

• High humidity levels typical of tropical climates can reduce panel efficiency and promote corrosion of electrical components
• Frequent rainfall during wet seasons may temporarily reduce solar output and require regular panel cleaning
• Salt air exposure from nearby coastal areas can accelerate corrosion and create mineral deposits on panel surfaces
• Volcanic ash from regional volcanic activity could coat panels and significantly reduce light transmission

Preventative Installation Measures

To maximize energy production despite these environmental challenges, several preventative measures should be implemented:

• Install panels with anti-corrosive mounting systems and marine-grade electrical components designed for high-humidity environments
• Implement regular cleaning schedules and consider automated cleaning systems to remove dust, salt, and debris accumulation
• Ensure adequate ventilation around panels to minimize moisture buildup and improve cooling efficiency
• Use protective coatings on electrical connections and junction boxes to prevent moisture infiltration
• Design drainage systems to quickly remove standing water from panel surfaces and mounting areas

Despite these environmental considerations, Banjar Pacung's consistent solar output levels indicate that with proper installation and maintenance practices, this location offers excellent potential for successful solar energy generation throughout the year.

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 Banjar Pacung

Seasonal solar PV output for Latitude: -8.5325, Longitude: 115.2212 (Banjar Pacung, 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 9° North in Banjar Pacung, Indonesia

To maximize your solar PV system's energy output in Banjar Pacung, Indonesia (Lat/Long -8.5325, 115.2212) throughout the year, you should tilt your panels at an angle of 9° 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 Banjar Pacung, 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 Banjar Pacung, Indonesia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 9° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
7° South in Summer	15° North in Autumn	24° North in Winter	3° 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.

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 Banjar Pacung, 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 Banjar Pacung, Indonesia

Topographical Features Around Banjar Pacung

Banjar Pacung sits within the central highlands of Bali, positioned in the island's mountainous interior region. The area is characterized by rolling hills and moderate elevation changes, with the landscape gradually rising toward the volcanic peaks that dominate Bali's central spine. The terrain here consists of undulating topography with gentle to moderate slopes, interspersed with valleys and ridgelines that create a varied but manageable landscape for development.

The region experiences typical tropical highland conditions, with the elevation providing cooler temperatures compared to Bali's coastal areas. The surrounding landscape is predominantly agricultural, featuring terraced rice fields, mixed farming plots, and patches of tropical vegetation. Small streams and seasonal watercourses cut through the terrain, creating minor drainage channels that follow the natural contours of the land.

To the north and east of Banjar Pacung, the terrain becomes increasingly mountainous as it approaches the major volcanic peaks of central Bali. Conversely, the southern and western areas tend toward gentler slopes and broader valleys, making these directions more accessible for large-scale infrastructure development.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for extensive solar photovoltaic installations would be found in the broader valley areas and gentler slopes to the southwest and west of Banjar Pacung. These areas offer several advantages including relatively flat or mildly sloping terrain that reduces construction complexity and costs. The wider valleys provide sufficient contiguous land area necessary for large-scale solar farms while maintaining reasonable access to existing road networks.

The southern approaches toward the coastal plains present particularly attractive opportunities, as the terrain gradually flattens and opens up into larger agricultural zones. These areas typically have fewer steep gradients and offer better potential for grid connectivity due to their proximity to more developed infrastructure corridors.

Areas with east and south-facing slopes would be preferable for solar installations, as they can capture optimal sun exposure throughout the day. The moderate elevation of the region provides an advantage over lower coastal areas by offering clearer atmospheric conditions and reduced humidity levels that can affect solar panel efficiency.

When considering site selection, the flatter agricultural zones and gently sloping hillsides would require minimal grading and earthwork, making them more economically viable for large installations. The existing agricultural road network in these areas also provides a foundation for the access infrastructure needed during construction and ongoing maintenance operations.
