Padang, West Sumatra, Indonesia is a very suitable location for generating solar energy all year round. This is because it's located in the tropics where sunlight is consistent throughout most of the year. The amount of electricity that can be generated from each kilowatt (kW) of installed solar power varies slightly by season, but not by much. You can expect to generate around 5.25 kilowatt-hours (kWh) per day in Summer, 5.13 kWh/day in Autumn, 5.27 kWh/day in Winter and 5.46 kWh/day in Spring.

This means that any time of the year would be good for generating solar power at this location, although Spring might be slightly better than other seasons due to higher daily output.

If you're installing fixed panels here, it's best to tilt them at an angle of one degree facing North to get the maximum total production from your solar PV system throughout the year.

However, there could be some local factors that may affect solar production at this location such as weather conditions or environmental issues - these need to be considered when setting up your system.

For instance, since Padang has wet and dry seasons instead of traditional four seasons like many places do; during wet season there might be more cloud cover which reduces sunlight exposure on panels thereby reducing their efficiency somewhat compared with dry season when skies are clearer.

There might also be dust or debris carried by wind during certain times which could settle on panels reducing their effectiveness too unless regularly cleaned off.

To counter these potential issues:

1) Consider installing a tracking system so your panels can follow sun’s path across sky maximizing exposure even on cloudy days.
2) Regular maintenance including cleaning should help keep your panels operating efficiently.
3) If possible try placing your installation where it won’t easily get covered by falling leaves or debris.
4) Using high-quality durable panels will help withstand harsh weather conditions better ensuring longer lifespan and better performance.

So, while there are some minor challenges to consider, Padang is generally a very good location for generating solar energy throughout the year.

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 Padang

Seasonal solar PV output for Latitude: -0.9497, Longitude: 100.3505 (Padang, 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:

Average 5.25kWh/day in Summer.

Average 5.13kWh/day in Autumn.

Average 5.27kWh/day in Winter.

Average 5.46kWh/day in Spring.

Ideally tilt fixed solar panels 1° North in Padang, Indonesia

To maximize your solar PV system's energy output in Padang, Indonesia (Lat/Long -0.9497, 100.3505) throughout the year, you should tilt your panels at an angle of 1° 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.

At Latitude: -0.9497, Longitude: 100.3505, the ideal angle to tilt panels is 1° North

Seasonally adjusted solar panel tilt angles for Padang, 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 Padang, Indonesia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 1° North tilt angle throughout the year.

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 Padang, 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 Padang, Indonesia.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Padang, Indonesia

Padang, the capital of West Sumatra province in Indonesia, is located on the western coast of Sumatra island. The city is situated near the equator and features a tropical rainforest climate. It is surrounded by coastal lowlands to the west and mountainous terrain to the east with several volcanoes such as Mount Marapi and Mount Singgalang.

The topography around Padang varies significantly from coastal plains to hilly and mountainous areas. The region's natural landscape includes beaches, rivers, lakes, forests as well as rice fields in rural areas.

For large-scale solar PV installations, flat or gently sloping terrains are usually preferred because they require less site preparation work compared to steep slopes which may also pose erosion risks. Therefore, considering local topography around Padang:

1) Coastal Plains: These areas would be suitable for large-scale solar PV projects due to their relatively flat terrain which facilitates installation and maintenance.

2) Agricultural Lands: If compatible with existing land uses (e.g., dual-use agrivoltaics), agricultural lands or rice fields could be potential sites for solar farms because they often have good sun exposure.

3) Industrial Zones: These areas might also be suitable if there's enough unused space available since they're typically well-connected with transportation networks facilitating equipment delivery and operation logistics.

However, it's important to note that suitability of an area for solar PV doesn't only depend on its physical characteristics but also involves other factors like local climatic conditions (solar irradiation levels), social-economic aspects (land ownership rights), environmental constraints (biodiversity conservation), infrastructure availability (grid connection points), etc., all of which should be carefully assessed during project planning stage.

Finally, given Padang’s location near equator where sunlight intensity is high throughout year could make it a potentially good candidate for solar power generation despite its frequent cloud cover due its tropical climate.

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.
