Tasikmalaya, West Java, Indonesia, located in the tropics, offers a promising environment for solar energy generation throughout the year. This location benefits from consistent sunlight and experiences wet and dry seasons rather than traditional four-season cycles.

Solar Energy Production Potential

The solar energy output at Tasikmalaya is relatively stable across all meteorological seasons. Autumn sees the highest production at 5.63 kWh per day for each kilowatt of installed solar capacity. Summer and spring follow closely with 5.15 kWh/day and 5.11 kWh/day, respectively. Winter experiences a slight dip but still maintains a respectable 4.99 kWh/day.

This consistency in energy production makes Tasikmalaya an ideal location for year-round solar power generation. The minimal fluctuation between seasons ensures a steady and reliable energy supply, which is advantageous for both residential and commercial applications.

Optimal Panel Installation

To maximize solar energy capture in Tasikmalaya, West Java, fixed solar panels should be tilted at an 8-degree angle facing north. This optimal tilt angle has been calculated considering the location's latitude, daily solar elevation angles, and NASA's solar irradiance data.

Environmental Considerations

While Tasikmalaya's tropical climate is generally favorable for solar energy production, there are some environmental factors to consider:

• Heavy rainfall during the wet season could potentially reduce solar efficiency.
• High humidity levels may lead to increased dust accumulation on panels.

To mitigate these issues, installing panels at the recommended angle helps with natural cleaning during rainfall. Regular maintenance and cleaning schedules should also be implemented to ensure optimal performance. Additionally, using high-quality, weather-resistant solar equipment designed for tropical climates can help maintain efficiency despite challenging weather conditions.

Overall, Tasikmalaya's location presents an excellent opportunity for solar energy production, with its consistent sunlight and relatively stable output across seasons making it a prime candidate for solar PV installations.

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 Tasikmalaya

Seasonal solar PV output for Latitude: -7.3263, Longitude: 108.221 (Tasikmalaya, 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 Tasikmalaya, Indonesia

To maximize your solar PV system's energy output in Tasikmalaya, Indonesia (Lat/Long -7.3263, 108.221) 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 Tasikmalaya, 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 Tasikmalaya, 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	1° 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 Tasikmalaya, 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 Tasikmalaya, 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 Tasikmalaya, Indonesia

Tasikmalaya, located in West Java, Indonesia, is surrounded by a diverse and picturesque topography that offers a mix of landscapes. The area is characterized by rolling hills, lush valleys, and expansive plains, creating a stunning backdrop for this Indonesian city. To the north of Tasikmalaya, the terrain gradually rises into the foothills of Mount Galunggung, an active stratovolcano that dominates the skyline. These slopes are covered in dense tropical forests and offer breathtaking views of the surrounding countryside. The volcanic soil in this region is incredibly fertile, supporting a variety of agricultural activities. Moving southward from the city, the landscape transitions into a more gently undulating terrain. This area is dotted with rice paddies, small villages, and scattered patches of woodland. The southern part of the region eventually gives way to coastal plains as it approaches the Indian Ocean. To the east and west of Tasikmalaya, the topography is primarily composed of low-lying hills and valleys. These areas are crisscrossed by numerous rivers and streams, which have carved out scenic gorges and waterfalls over time. The combination of hills and waterways creates a patchwork of microclimates and ecosystems.

Potential for Large-scale Solar PV

When considering areas nearby Tasikmalaya for large-scale solar PV installations, several factors come into play. The most suitable locations would be those with ample sunlight exposure, relatively flat terrain, and minimal environmental impact. The plains to the south of Tasikmalaya present the most promising opportunity for solar PV development. These areas receive consistent sunlight throughout the year and offer large, open spaces that could accommodate extensive solar arrays. The flat terrain would minimize the need for extensive land preparation, reducing installation costs and environmental disruption. Another potential area for solar PV development lies in the gently rolling hills to the east and west of the city. While these locations may require some land contouring, they offer the advantage of being away from densely populated areas and prime agricultural land. The slight elevations could also provide natural cooling for the solar panels, potentially increasing their efficiency. It's important to note that while the northern regions near Mount Galunggung receive ample sunlight, the steep terrain and forested areas make large-scale solar installations less feasible in this part of the region. Additionally, the volcanic activity in this area could pose risks to solar infrastructure. In conclusion, the diverse topography around Tasikmalaya offers several options for solar PV development, with the southern plains and eastern and western hills being the most promising locations. Any large-scale solar projects in the region would need to carefully balance energy production goals with environmental conservation and local community needs.
