Karawaci, West Java, Indonesia, located at latitude -6.193 and longitude 106.6261, offers a promising environment for solar energy generation throughout the year. This tropical location experiences consistent sunlight, with seasons characterized more by wet and dry periods rather than traditional temperature-based seasons.

Year-round Solar Performance

The solar energy potential in Karawaci remains relatively stable across all meteorological seasons. Spring yields the highest output at 5.40 kWh per day for each kilowatt of installed solar capacity, closely followed by autumn at 5.33 kWh/day. Winter maintains a strong performance at 5.06 kWh/day, while summer produces a slightly lower but still significant 4.68 kWh/day. This consistent performance throughout the year makes Karawaci an ideal location for solar PV installations, as it ensures a steady energy supply without significant seasonal fluctuations.

Optimal Panel Tilt

For fixed solar panel installations in Karawaci, West Java, the ideal tilt angle to maximize year-round energy production is 7 degrees facing North. This slight tilt helps optimize the panels' exposure to sunlight throughout the year, accounting for the location's proximity to the equator and the Earth's elliptical orbit.

Environmental Considerations

While Karawaci's tropical climate is generally favorable for solar energy production, there are some environmental factors to consider: 1. Heavy rainfall during the wet season: This could temporarily reduce solar panel efficiency due to cloud cover and direct rainfall on panels. 2. High humidity levels: Moisture can potentially affect electrical components if not properly protected. To mitigate these factors, consider the following preventative measures:

• Install high-quality, weather-resistant solar panels and components
• Ensure proper sealing and insulation of all electrical connections
• Implement a regular cleaning and maintenance schedule to prevent dust and debris accumulation
• Use anti-reflective coatings on panels to maximize light absorption, even in overcast conditions

By addressing these considerations, solar installations in Karawaci can maintain high efficiency and durability, taking full advantage of the location's excellent year-round solar potential.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 151 locations across Indonesia. 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 Karawaci

Seasonal solar PV output for Latitude: -6.193, Longitude: 106.6261 (Karawaci, 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 Karawaci, Indonesia

To maximize your solar PV system's energy output in Karawaci, Indonesia (Lat/Long -6.193, 106.6261) 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 Karawaci, 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 Karawaci, 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	13° 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 Karawaci, 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 Karawaci, 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 Karawaci, Indonesia

Karawaci, located in the Tangerang Regency of Banten Province, Indonesia, is situated on the western outskirts of Jakarta. The topography of this area is predominantly flat, with minimal elevation changes across the landscape. The region is part of the larger Jakarta metropolitan area, which is characterized by its low-lying coastal plain. The terrain around Karawaci is primarily composed of urban and suburban developments, interspersed with patches of agricultural land and remnants of tropical vegetation. The area is crisscrossed by numerous small rivers and canals, which are part of the broader water management system of the Jakarta region. These waterways contribute to the overall flatness of the landscape, as they have shaped the terrain over time through natural erosion and sedimentation processes. To the north of Karawaci, the land gradually slopes towards the Java Sea, with coastal areas featuring mangrove forests and mudflats. To the south, the terrain begins to rise slightly, transitioning into gently rolling hills as one moves further inland towards the mountains of West Java.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The flat terrain surrounding Karawaci offers some advantages for solar development, as it minimizes the need for extensive land preparation and allows for efficient panel layout. The most promising areas for large-scale solar PV installations would likely be found to the south and southeast of Karawaci, where there are still some open spaces and agricultural lands. These areas benefit from slightly higher elevations, which can reduce the risk of flooding – a significant concern in this low-lying region. Additionally, moving away from the densely populated urban core provides more available land for expansive solar farms. However, it's important to note that the entire region around Karawaci faces challenges for solar PV development due to its proximity to Jakarta. The metropolitan area's air pollution and frequent cloud cover can potentially reduce solar irradiance and panel efficiency. Furthermore, the high population density and rapid urban expansion limit the availability of suitable large plots of land for solar installations. Despite these challenges, the Indonesian government's push for renewable energy development may lead to innovative solutions, such as floating solar PV systems on nearby reservoirs or the integration of solar panels into new urban developments. These approaches could help overcome the land scarcity issues while contributing to the region's sustainable energy goals.
