Menteng, Indonesia presents a relatively favorable location for year-round solar PV energy generation, with consistent electricity output throughout all seasons due to its tropical climate where sunlight remains fairly stable across the year.

Solar Energy Production Performance

The solar energy output at this location shows good consistency, with daily electricity generation ranging from 4.71 kWh per kW of installed solar capacity in summer up to 5.42 kWh per kW in spring. Spring and autumn emerge as the peak production seasons, delivering 5.42 kWh/day and 5.35 kWh/day respectively, while winter maintains solid performance at 5.04 kWh/day. For optimal year-round energy capture, solar panels should be installed at a fixed tilt angle of 7 degrees facing north. This relatively shallow angle maximizes total annual solar production by accounting for the location's proximity to the equator and seasonal variations in sun position.

Environmental and Weather Challenges

Several significant factors in Menteng can impact solar panel performance and require careful consideration during installation:

• High humidity and frequent rainfall: Indonesia's tropical climate brings intense wet seasons that can reduce solar irradiance and create moisture-related issues
• Dust and pollution accumulation: Urban air quality in Jakarta can lead to faster dirt buildup on panel surfaces
• Extreme heat: High ambient temperatures can reduce panel efficiency and accelerate component degradation
• Potential for severe weather: Tropical storms and heavy rainfall events may pose structural risks

Preventative Installation Measures

To maximize energy production despite these challenges, several installation strategies prove essential. Implementing a regular cleaning schedule becomes crucial, with monthly panel washing recommended during dry periods and more frequent cleaning during dusty conditions. Proper drainage design prevents water pooling around installations, while elevated mounting systems improve air circulation and cooling. Using corrosion-resistant materials and sealed electrical connections protects against humidity damage. Installing panels with adequate spacing allows for better airflow and cooling, helping maintain efficiency during hot periods. Robust mounting systems designed for tropical conditions ensure structural integrity during severe weather events. Regular maintenance and monitoring systems help identify performance issues early, ensuring the solar installation continues delivering optimal energy output throughout Indonesia's varying seasonal conditions.

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 Menteng

Seasonal solar PV output for Latitude: -6.2268, Longitude: 106.8382 (Menteng, 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 Menteng, Indonesia

To maximize your solar PV system's energy output in Menteng, Indonesia (Lat/Long -6.2268, 106.8382) 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 Menteng, 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 Menteng, 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 Menteng, 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 Menteng, 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 Menteng, Indonesia

Topography Around Menteng

Menteng sits in the heart of Jakarta, Indonesia's bustling capital city, positioned on the relatively flat coastal plain of northern Java. The area itself represents one of Jakarta's most established urban districts, characterized by gently undulating terrain with minimal elevation changes. The topography here is predominantly flat to very gently rolling, with elevations typically ranging from just a few meters above sea level to approximately 15-20 meters at the highest points.

The immediate surroundings of Menteng consist of dense urban development, with tree-lined streets and established neighborhoods that were originally planned as garden suburbs during the Dutch colonial period. The area benefits from a grid-like street pattern with relatively wide boulevards, though the mature tree canopy provides significant shade coverage throughout much of the district.

Moving outward from Menteng, the broader Jakarta metropolitan area maintains this generally flat character, as the entire region sits within the Jakarta Bay coastal plain. To the south, the land begins a very gradual rise toward the foothills of the volcanic highlands that characterize much of Java's interior, but this transition occurs over many kilometers and represents only modest elevation gains within the immediate metropolitan area.

Optimal Areas for Large-Scale Solar Development

The flat topography around Menteng and throughout the greater Jakarta region presents both opportunities and challenges for large-scale solar photovoltaic installations. The minimal slopes and generally level terrain would be ideal for solar arrays from a construction and maintenance perspective, as flat ground reduces installation complexity and allows for optimal panel positioning without significant grading work.

However, the dense urban nature of Menteng itself makes it unsuitable for large-scale ground-mounted solar installations. The most promising areas for substantial solar development would be found in the outer reaches of the Jakarta metropolitan region, particularly to the east and southeast where industrial zones and less densely populated areas offer larger parcels of available land.

The coastal areas to the north of Jakarta, while topographically suitable, present challenges due to proximity to the sea and associated humidity and salt air concerns. More favorable locations would be the industrial corridors extending eastward from the city center, where flat former agricultural land has been converted to industrial use but still contains large open spaces suitable for solar installations.

Areas around Bekasi and Karawang, roughly 20-40 kilometers east of Menteng, offer particularly attractive conditions. These regions maintain the flat topography ideal for solar installations while providing sufficient space for large-scale developments. The land here remains relatively affordable compared to central Jakarta locations, and the existing industrial infrastructure provides good access to electrical grid connections necessary for utility-scale solar projects.

The southern approaches to Jakarta, while beginning to show more topographical variation as they approach Java's volcanic spine, still contain extensive flat areas within 50 kilometers of Menteng that could accommodate large solar installations. These areas benefit from being inland enough to avoid coastal weather concerns while maintaining the favorable flat terrain characteristics of the broader Jakarta plain.
