Solar PV Analysis of Banjarmasin, Indonesia
Banjarmasin, South Kalimantan, Indonesia is a very good location for generating solar energy all year round due to its tropical climate. The amount of sunlight it gets doesn't change much throughout the year and there's no real difference between the seasons apart from more rain during some parts of the year.
The amount of electricity that can be generated from each kilowatt (kW) of installed solar panels varies slightly with each season. It's highest in Autumn, producing about 5.59 kilowatt-hours (kWh) per day, followed by Spring with around 5.17 kWh/day, Winter at around 5.10 kWh/day and Summer at approximately 4.74 kWh/day.
So while you'll get a bit more electricity in Autumn and Spring compared to Winter and Summer, overall it's pretty consistent throughout the year which makes this an ideal location for solar power generation.
When installing solar panels here, they should be tilted at an angle of about 4 degrees towards the North for maximum efficiency.
However, there might be certain local factors that could potentially affect how much electricity your solar panels produce here. For instance, Banjarmasin has a tropical rainforest climate which means it gets quite a lot of rainfall especially during the wet season which typically runs from November through March.
Heavy rainfall or cloud cover can reduce how much sunlight reaches your panels thereby reducing their output but since this generally occurs only part-time even during rainy days and not every day during these months - overall annual production is still high in comparison to many other locations globally where winter snow or long periods without sun occur annually.
To mitigate against potential losses caused by heavy rain or cloudy weather conditions on those days when they do occur; if budget allows you may want to consider installing additional PV capacity so as to offset such potential losses ensuring optimal production levels are maintained across all seasons/year-round.
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 Banjarmasin
Seasonal solar PV output for Latitude: -3.3219, Longitude: 114.5871 (Banjarmasin, 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 4° North in Banjarmasin, Indonesia
To maximize your solar PV system's energy output in Banjarmasin, Indonesia (Lat/Long -3.3219, 114.5871) throughout the year, you should tilt your panels at an angle of 4° 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 Banjarmasin, 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 Banjarmasin, Indonesia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 4° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 12° South in Summer | 10° North in Autumn | 19° North in Winter | 3° South 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 Banjarmasin, 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 Banjarmasin, 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 Banjarmasin, Indonesia
Banjarmasin is located in the South Kalimantan province of Indonesia. The topography around this region is relatively flat, with some low-lying areas prone to flooding. It's characterized by coastal plains and swamps, along with some forested regions.
The climate in Banjarmasin is tropical, which means it receives a significant amount of sunlight throughout the year. This makes it suitable for large-scale solar PV installations.
However, the most suited areas for such installations would be those that are not prone to flooding and have minimal vegetation cover. Flat open spaces or rooftops in urban areas could be ideal locations as they provide ample space for installation and allow maximum exposure to sunlight.
It's important to note that while Banjarmasin can harness solar energy efficiently due to its location near the equator, considerations like high humidity levels and frequent rainfall might affect the efficiency of solar panels over time. Therefore proper maintenance and choosing appropriate technology adapted to these conditions will play an important role in ensuring successful large-scale solar PV projects.
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.
