Solar PV Analysis of South Tangerang, Indonesia
In South Tangerang, Banten, Indonesia, situated at latitude -6.2876 and longitude 106.722, the average daily energy produced per kW of installed solar capacity varies with each season: summer yields 4.68 kWh, autumn produces 5.33 kWh, winter generates 5.06 kWh, while spring tops at 5.40 kWh.
The location's tropical climate and dry seasons typically ensure a consistent supply of sunlight to facilitate solar power generation throughout the year; however, energy production may be somewhat lower during the summer months compared to other seasons.
Nonetheless, there are factors that could potentially impede solar production in this region. Heavy rainfall and excessive cloud cover can significantly reduce the amount of direct sunlight reaching the solar cells thus limiting energy output.
To mitigate these potential disruptions in energy production due to weather conditions in South Tangerang's tropical climate zone, it is recommended to install panels with high efficiency ratings that can absorb more diffuse light on cloudy days or during heavy rainfalls.
Furthermore, for fixed panel installations in this location specifically , an optimal tilt angle towards North by approximately seven degrees has been identified as ideal for maximizing exposure to sunlight across different times of day and throughout varying seasons ensuring greater overall energy output from your installation.
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 South Tangerang
Seasonal solar PV output for Latitude: -6.2876, Longitude: 106.722 (South Tangerang, 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 South Tangerang, Indonesia
To maximize your solar PV system's energy output in South Tangerang, Indonesia (Lat/Long -6.2876, 106.722) 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 South Tangerang, 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 South Tangerang, 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 South Tangerang, 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 South Tangerang, Indonesia.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 South Tangerang, Indonesia
The topography around South Tangerang, Indonesia is generally flat with occasional rolling hills. Areas that would be most suitable for large-scale solar PV installations would be those with open spaces and good access to sunlight. Flat areas such as agricultural lands and grasslands are ideal locations for these types of installations as they require minimal land preparation and provide the most direct line of sight to the sun. Additionally, any area that has a lack of trees or other obstructions can also be beneficial in maximizing solar energy production.
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. These include tax exemptions, subsidies, feed-in tariffs, and other financial incentives. Additionally, the government has established a Renewable Energy Fund which provides grants for research and development projects related to renewable energy technologies.
