Banyuwangi, East Java, Indonesia, located at latitude -8.2471 and longitude 114.3878, presents a favorable environment for solar energy generation throughout the year. Situated in the tropics, this location benefits from consistent sunlight and experiences wet and dry seasons rather than traditional four-season weather patterns.

Seasonal Solar Performance

The solar energy output in Banyuwangi remains relatively stable across all seasons, with slight variations:

• Summer: 5.46 kWh/day
• Autumn: 6.09 kWh/day
• Winter: 5.62 kWh/day
• Spring: 6.04 kWh/day

These figures represent the expected electricity output per kilowatt of installed solar capacity.

Optimal Generation Periods

The data suggests that autumn and spring are the most productive seasons for solar energy generation in Banyuwangi. However, the difference between the highest and lowest producing seasons is relatively small, indicating consistent year-round performance. This stability is advantageous for maintaining a reliable solar energy supply throughout the year.

Panel Tilt Angle

For fixed panel installations in Banyuwangi, East Java, the ideal tilt angle to maximize year-round solar production is 9 degrees North. This angle has been calculated taking into account the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data.

Environmental Considerations

While Banyuwangi's tropical climate is generally conducive to solar energy production, there are some environmental factors to consider: 1. Rainfall: The region experiences a wet season, which could potentially reduce solar efficiency. To mitigate this, panels should be installed at an angle that allows for natural cleaning by rainwater. 2. Humidity: High humidity levels can lead to condensation on panels. Using anti-reflective coatings and ensuring proper ventilation can help combat this issue. 3. Volcanic activity: Banyuwangi is located in a volcanically active region. Ash from eruptions could temporarily reduce panel efficiency. Regular cleaning and maintenance schedules should be implemented to address this potential issue.

Despite these considerations, the consistent sunlight and relatively stable output across seasons make Banyuwangi an ideal location for solar PV installations. With proper planning and maintenance, solar energy systems in this area can provide reliable and efficient power generation 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 Banyuwangi

Seasonal solar PV output for Latitude: -8.2471, Longitude: 114.3878 (Banyuwangi, 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 9° North in Banyuwangi, Indonesia

To maximize your solar PV system's energy output in Banyuwangi, Indonesia (Lat/Long -8.2471, 114.3878) throughout the year, you should tilt your panels at an angle of 9° 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 Banyuwangi, 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 Banyuwangi, Indonesia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 9° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
8° South in Summer	15° North in Autumn	24° North in Winter	3° 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 Banyuwangi, 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 Banyuwangi, 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 Banyuwangi, Indonesia

Banyuwangi, located on the eastern tip of Java, Indonesia, boasts a diverse and captivating topography. The region is characterized by a striking blend of coastal plains, rolling hills, and mountainous terrain. Along the eastern coast, where Banyuwangi city sits, the land is relatively flat and low-lying, with sandy beaches and mangrove forests fringing the shoreline. This coastal plain gradually rises towards the west, giving way to undulating hills and valleys. As one moves further inland, the landscape becomes more dramatic, with the imposing presence of the Ijen volcano complex dominating the western horizon. This volcanic range features steep slopes, dense forests, and the famous turquoise-colored crater lake of Ijen. The area surrounding the volcano is marked by rugged terrain, deep ravines, and lush vegetation, creating a stark contrast to the coastal lowlands.

Potential Areas for Large-Scale Solar PV

When considering suitable locations for large-scale solar photovoltaic (PV) installations near Banyuwangi, several factors come into play. The most promising areas would likely be found in the gently sloping regions between the coastal plains and the mountainous interior. These areas offer a good balance of open space, relatively flat terrain, and proximity to existing infrastructure. The northern parts of Banyuwangi Regency, particularly around the subdistricts of Wongsorejo and Kalipuro, could be well-suited for solar PV development. These areas feature expansive agricultural lands and less densely populated zones, providing ample space for large installations. The terrain here is generally flatter compared to the volcanic regions to the west, which would simplify construction and maintenance of solar arrays. Another potential location could be the southern coastal areas, such as the regions around Pesanggaran and Siliragung subdistricts. These areas benefit from high levels of solar radiation due to their proximity to the coast and have relatively flat topography. However, care would need to be taken to avoid environmentally sensitive areas like mangrove forests and protected beaches. It's important to note that while the mountainous regions to the west receive ample sunlight, their steep slopes and forested nature make them less suitable for large-scale solar installations. The rugged terrain would pose significant challenges for construction and maintenance, and clearing forested areas for solar farms would likely have negative environmental impacts. In all cases, detailed site-specific assessments would be necessary to determine the most suitable locations, taking into account factors such as land availability, grid connectivity, environmental considerations, and local community needs.
