Solar PV Analysis of Pontianak, Indonesia
Pontianak, West Kalimantan, Indonesia is a great location for solar energy production all year round. The amount of electricity you can expect to generate from each kilowatt of installed solar power doesn't vary much with the seasons - it's around 5.6 to 5.8 kilowatt-hours per day in every season (summer, autumn, winter and spring). This means that the sun shines consistently throughout the year.
The best time to generate solar power at this location would be during autumn when the output reaches its peak at 5.88kWh/day per kW of installed solar. However, even in winter, which has slightly less output at 5.47kWh/day per kW, it's still a good time for generating solar energy due to Pontianak’s tropical climate which offers consistent sunlight most times of the year.
For fixed panel installations in Pontianak, West Kalimantan, you'll get maximum yearly production if your panels are tilted at an angle of zero degrees – so they should lie flat rather than being angled towards the sky.
There may be some local factors that could affect your ability to generate solar power here though - particularly weather conditions like heavy rainfall or cloud cover during wet seasons as these can reduce sunlight exposure on your panels and therefore lower their efficiency. To prevent this from becoming a problem and ensure greater energy production throughout the year:
1) Regularly clean your panels: Dust or debris accumulated on your panels can block sunlight and reduce their efficiency.
2) Install a tracking system: A tracking system automatically moves your panels so they're always facing directly towards the sun.
3) Use high-quality PV modules: These are designed to work well even under cloudy conditions.
4) Ensure proper installation: Make sure there aren’t any objects blocking direct sunlight onto your panels such as trees or buildings nearby.
Remember though that these measures might involve additional costs upfront but will help ensure better performance from your PV system over its lifespan.
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 Pontianak
Seasonal solar PV output for Latitude: -0.031, Longitude: 109.3257 (Pontianak, 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 0° in Pontianak, Indonesia
To maximize your solar PV system's energy output in Pontianak, Indonesia (Lat/Long -0.031, 109.3257) throughout the year, you should tilt your panels at an angle of 0° 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 Pontianak, 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 Pontianak, Indonesia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 0° tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 15° South in Summer | 6° North in Autumn | 16° North in Winter | 6° 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 Pontianak, 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 Pontianak, 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 Pontianak, Indonesia
Pontianak, Indonesia is located on the equator and is part of the West Kalimantan province. The topography around Pontianak is largely flat, as it's situated in a delta area where the Kapuas and Landak rivers meet before flowing into the South China Sea. This region also includes swamps and coastal areas.
The large amount of sunlight received due to its location on the equator makes Pontianak an ideal location for solar PV installation. However, there are some challenges due to weather conditions such as frequent cloud cover and rainfall which can reduce solar irradiance levels.
Large-scale solar PV installations would be most suited in areas with minimal shading throughout the day. Given that much of Pontianak's surrounding area is relatively flat, this provides ample opportunity for large-scale ground-mounted solar farms provided there isn't significant tree coverage or other obstructions.
Areas slightly further inland away from dense vegetation or swampy regions may provide more suitable locations for larger scale projects given better soil stability. Also, any potential project should consider local land use patterns including agriculture and urban development which could limit available space or create conflicts with existing uses.
Lastly, it's worth noting that while large-scale solar could certainly play a role in meeting energy needs in this region, complementary solutions like small-scale rooftop solar systems might also be particularly well-suited to local conditions given high population density in urban areas like Pontianak city itself.
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.
