Solar PV Analysis of Bandar Lampung, Indonesia
The location at Bandar Lampung, Indonesia is very good for generating energy via solar panels all year round. This is because it's located in the Tropics where sunlight is pretty much constant throughout the year. The amount of electricity that can be produced from each kilowatt of installed solar varies slightly with the seasons but not by much; you can expect to get around 5.16kWh/day in summer, 5.60kWh/day in autumn, 5.02kWh/day in winter and 5.56kWh/day in spring.
To make sure you're getting as much energy as possible from your solar panels at this location, you'll want to tilt them at an angle of 5 degrees towards the north. This will help maximize their exposure to sunlight throughout the year.
As for factors that could potentially reduce how effective your solar panels are at producing energy, there aren't many significant ones here due to its tropical climate which ensures consistent sun exposure almost all-year-round.
However, since seasons here are characterized more by wet and dry periods rather than traditional four seasons like we have further away from the equator; during wet season there might be extended periods of cloud cover or heavy rainfall which could temporarily reduce efficiency of your solar panels by blocking out sunlight.
In order to mitigate these potential issues and ensure greater energy production, when installing your solar panels you may want to consider having a system that allows you to adjust their angle depending on time of year or weather conditions - this way they can still catch as much light as possible even during less sunny periods.
Also another preventative measure would be keeping them clean especially after heavy rainfalls so dirt or debris doesn't block any incoming light either.
Overall though given its tropical setting with lots of sun most days out of a year; Bandar Lampung would generally be considered an excellent place for harnessing power through photovoltaic (PV) solar energy.
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 Bandar Lampung
Seasonal solar PV output for Latitude: -5.4291, Longitude: 105.2615 (Bandar Lampung, 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° North in Bandar Lampung, Indonesia
To maximize your solar PV system's energy output in Bandar Lampung, Indonesia (Lat/Long -5.4291, 105.2615) throughout the year, you should tilt your panels at an angle of 5° 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 Bandar Lampung, 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 Bandar Lampung, Indonesia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 5° 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 | 21° North in Winter | 1° 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 Bandar Lampung, 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 Bandar Lampung, 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 Bandar Lampung, Indonesia
Bandar Lampung is located in the southern part of Sumatra, Indonesia. The topography of this region is diverse, with coastal plains near the city transitioning into hilly and mountainous terrain as one moves inland. The city itself is relatively flat.
The coastal areas around Bandar Lampung are relatively flat and would be suitable for large-scale solar PV installations. These areas receive a significant amount of sunlight throughout the year, which could be harnessed for solar power generation.
However, it's important to note that while these areas might be physically suitable for solar PV installations, other factors such as land ownership, access to grid infrastructure and environmental considerations also need to be taken into account when planning such projects.
Furthermore, rooftops in urban areas like Bandar Lampung city itself could potentially be used for smaller scale distributed solar PV systems. This approach can help to reduce transmission losses and contribute to local energy security without requiring additional land resources.
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.
