Solar PV Analysis of Magelang, Indonesia
Magelang, Central Java, Indonesia is a very promising location for generating energy through solar photovoltaic (PV) panels all year round. This is due to its tropical climate where sunlight remains consistent throughout the year. The average amount of electricity you can expect your solar PV system to produce varies slightly with each season: in Summer it's about 4.94 kilowatt-hours (kWh) per day for every kilowatt (kW) of solar you have installed; in Autumn it increases to about 5.57 kWh/day per kW; in Winter it’s around 5.52 kWh/day per kW; and Spring gives the highest output at approximately 5.73 kWh/day per kW.
The best time of year for generating solar energy here would be during Spring, followed closely by Autumn and Winter, with Summer producing slightly less power on average.
For fixed panel installations at this location, tilting the panels at an angle of 8 degrees North will maximize total yearly production from your PV system.
As far as environmental or weather factors that could impede solar production in Magelang - these are not significant enough to pose major issues. However, like any other place located within the tropics, Magelang experiences wet and dry seasons which may affect overall performance slightly due to cloud cover during rainy periods reducing sunlight exposure on panels.
To ensure greater energy production despite these factors, one preventative measure that can be taken when installing solar panels is ensuring they are kept clean and free from dust or debris accumulation which could block sunlight reaching them - especially important during drier times when dust levels may increase.
Also consider installing systems that track the sun's movement across the sky throughout the day for maximum light capture rather than static ones if budget allows as this will help offset any slight reductions in performance due to weather variations across different seasons.
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 27 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 Magelang
Seasonal solar PV output for Latitude: -7.4702, Longitude: 110.2213 (Magelang, 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 8° North in Magelang, Indonesia
To maximize your solar PV system's energy output in Magelang, Indonesia (Lat/Long -7.4702, 110.2213) throughout the year, you should tilt your panels at an angle of 8° 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 Magelang, 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 Magelang, Indonesia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 8° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 9° South in Summer | 14° North in Autumn | 23° North in Winter | 2° 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.
Topography for solar PV around Magelang, Indonesia
Magelang, Indonesia is located in Central Java and is surrounded by mountains. The region has a hilly topography with Mount Merbabu to the east, Mount Sumbing and Mount Sundoro to the west, and the Menoreh Hills to the south. The city itself lies in a fertile plain between these mountainous regions.
The most suitable areas for large-scale solar PV installations would be flat plains or gently sloping areas that receive high amounts of sunlight throughout the year. Considering Magelang's location within a valley, it may not be ideal for such installations due to potential shading from surrounding mountains.
However, nearby flatter regions or plateaus might be more suitable. It could also be possible to install solar panels on rooftops within urban areas of Magelang city itself where there are no obstructions blocking sunlight.
Finally, any decision regarding locations for solar PV should also take into account other factors like accessibility (for installation and maintenance), proximity to transmission lines or grids (to transport generated electricity), land use restrictions or regulations etc., which require detailed local knowledge and feasibility studies.
