Pulogadung, Jakarta, Indonesia, located at latitude -6.1804 and longitude 106.9038, offers a favorable environment for solar energy generation throughout the year. This tropical location experiences consistent sunlight, with seasons primarily characterized by wet and dry periods rather than traditional temperature-based seasons.

Solar Energy Potential

The solar energy potential in Pulogadung is impressive, with relatively high and stable electricity output across all meteorological seasons. Spring yields the highest production at 5.42 kWh per day for each kilowatt of installed solar capacity, followed closely by autumn at 5.33 kWh/day. Winter and summer also show strong performance, generating 5.03 kWh/day and 4.68 kWh/day, respectively.

This consistent output throughout the year makes Pulogadung an ideal location for solar PV installations. The minimal variation between seasons ensures a reliable energy supply, with spring and autumn being particularly productive periods.

Optimal Panel Tilt

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

Environmental Considerations

While Pulogadung's tropical climate is generally favorable for solar energy production, there are some environmental factors to consider:

• Heavy rainfall during the wet season may temporarily reduce solar panel efficiency.
• High humidity levels can potentially lead to moisture buildup on panels.

To mitigate these issues, installers should consider using water-resistant panel coatings and ensuring proper drainage systems are in place. Regular cleaning and maintenance of the panels can also help maintain optimal performance in this tropical environment.

Overall, Pulogadung's location offers excellent potential for solar energy generation, with consistent output throughout the year and only minor environmental challenges that can be effectively addressed through proper installation and maintenance practices.

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 Pulogadung

Seasonal solar PV output for Latitude: -6.1804, Longitude: 106.9038 (Pulogadung, 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 Pulogadung, Indonesia

To maximize your solar PV system's energy output in Pulogadung, Indonesia (Lat/Long -6.1804, 106.9038) 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 Pulogadung, 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 Pulogadung, 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 Pulogadung, 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 Pulogadung, 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 Pulogadung, Indonesia

The area around Pulogadung, Indonesia, is characterized by a relatively flat urban landscape. Located in the eastern part of Jakarta, the capital city of Indonesia, Pulogadung sits on a low-lying coastal plain. The topography is predominantly level, with minimal natural elevation changes. This area is densely populated and heavily developed, featuring a mix of industrial, commercial, and residential zones. The surrounding region is part of the greater Jakarta metropolitan area, which extends across a vast alluvial plain formed by sediment deposits from numerous rivers that flow through the city. As you move further from the city center, the terrain gradually becomes more varied, with some gentle hills and slightly more pronounced elevation changes to the south and east.

Potential for Solar PV Development

When considering areas nearby that would be most suited to large-scale solar PV installations, it's important to look beyond the immediate urban environment of Pulogadung. The densely built-up nature of the city makes it challenging to find suitable open spaces for extensive solar farms within the urban core. However, the regions to the east and southeast of Jakarta, in the direction of West Java province, offer more promising opportunities for solar PV development. These areas, which include parts of the Bekasi and Karawang regencies, have several advantageous characteristics: 1. They feature more open, undeveloped land that could potentially accommodate large-scale solar installations. 2. The terrain in these areas is generally flat or gently rolling, which is ideal for solar panel placement and minimizes installation costs. 3. These regions receive ample sunlight throughout the year, thanks to Indonesia's tropical climate and proximity to the equator. 4. The proximity to Jakarta means that the energy generated could be easily transmitted to meet the high power demands of the metropolitan area. It's worth noting that while these areas show promise, any large-scale solar PV project would need to carefully consider factors such as land use, environmental impact, and local regulations. Additionally, the conversion of agricultural land for solar farms would need to be balanced against food security concerns in this densely populated region.

Indonesia solar PV Stats as a country

Indonesia ranks 71st in the world for cumulative solar PV capacity, with 211 total MW's of solar PV installed. Each year Indonesia is generating 1 Watts from solar PV per capita (Indonesia ranks 88th in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in Indonesia?

Yes, there are several incentives for businesses wanting to install solar energy in Indonesia. The Indonesian government has implemented a number of policies and programs to encourage the adoption of renewable energy sources such as solar power.
