Solar PV Analysis of Banda Aceh, Indonesia
Banda Aceh, Indonesia is an excellent location for generating solar energy all year round. This is due to its tropical climate which ensures consistent sunlight throughout most of the year. The amount of electricity that can be produced from each kilowatt (kW) of installed solar power varies slightly by season, but it's generally high: 5.36 kilowatt-hours (kWh) per day in summer, 5.17 kWh/day in autumn, 5.60 kWh/day in winter and 5.86 kWh/day in spring.
This means that you can expect a steady supply of solar energy throughout the year with slight increases during the winter and spring months making them the most ideal time for generating solar energy at this location.
If you're installing fixed panel installations at this location, tilting your panels at an angle of 5 degrees towards the south would maximize your total yearly production from your photovoltaic (PV) system.
However, there are some factors specific to Banda Aceh that could potentially affect your solar production output such as dust or dirt accumulation on panels due to local weather conditions or environmental factors like heavy rainfall during wet seasons which could lead to potential shading or soiling losses reducing overall efficiency of PV systems.
To counteract these issues and ensure greater energy production:
1. Regular maintenance and cleaning: Panels should be cleaned regularly especially during dry seasons when dust accumulation might be higher.
2. Installation Design: Consider designs that allow easy access for cleaning and maintenance.
3. Protective measures against rainfalls: During installation process consider protective measures such as adequate mounting structures ensuring panels are secure against heavy rainfalls.
4. Monitoring System Performance: Regularly monitor system performance to detect any irregularities early on enabling proactive troubleshooting before significant losses occur.
Overall though these potential impediments aren't major ones; with proper planning and regular upkeep they can easily be managed making Banda Aceh a highly suitable place for solar energy production.
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 Banda Aceh
Seasonal solar PV output for Latitude: 5.5418, Longitude: 95.3413 (Banda Aceh, 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 5° South in Banda Aceh, Indonesia
To maximize your solar PV system's energy output in Banda Aceh, Indonesia (Lat/Long 5.5418, 95.3413) throughout the year, you should tilt your panels at an angle of 5° South 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 Banda Aceh, 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 Banda Aceh, Indonesia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 5° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 10° North in Summer | 11° South in Autumn | 21° South 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 Banda Aceh, 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 Banda Aceh, 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 Banda Aceh, Indonesia
Banda Aceh is located on the northern tip of Sumatra Island in Indonesia. The topography mainly consists of coastal lowlands, with some hilly and mountainous areas further inland. The city itself is quite flat as it is situated along the coast.
The region receives a significant amount of sunlight throughout the year due to its location near the equator, making it suitable for solar PV installations. However, considering topographical constraints for large-scale solar PV projects such as land availability and gradient, flatter areas would be more suitable.
Therefore, coastal plains around Banda Aceh or cleared agricultural lands could potentially accommodate large scale solar PV installations. Also, any unused or underutilized flat spaces within the city like rooftops or parking lots could also be considered for smaller-scale installations.
However, feasibility would also depend on other factors including local regulations and policies regarding renewable energy projects, proximity to power grids for connectivity and distribution purposes etc. Therefore a detailed site-specific study would need to be conducted before deciding on potential locations.
It's also important to note that Banda Aceh was severely affected by a tsunami in 2004 caused by an undersea earthquake off its coast which resulted in massive loss of life and property. Hence any infrastructure planning should take into account risks associated with such natural disasters.
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.
