The location of Pati, Central Java, Indonesia, situated at latitude -6.7559 and longitude 111.038, presents a favorable environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than significant temperature fluctuations.

Solar PV installations in Pati demonstrate impressive electricity output across all meteorological seasons. Spring yields the highest production at 5.88 kWh per day for each kilowatt of installed solar capacity. This is closely followed by autumn at 5.69 kWh/day, winter at 5.49 kWh/day, and summer at 4.79 kWh/day. These figures indicate a relatively stable energy production throughout the year, with only minor variations between seasons.

The most productive periods for solar generation in Pati occur during the dry season, typically from April to October. During these months, clearer skies and reduced cloud cover allow for maximum solar irradiance, resulting in higher energy yields. However, the consistency of output across seasons suggests that solar PV systems in this location can provide reliable energy generation year-round.

Optimal Panel Installation

For fixed panel installations in Pati, Central Java, the ideal tilt angle to maximize year-round solar production is 7 degrees facing North. This slight tilt helps optimize the panels' exposure to sunlight throughout the year, accounting for the location's proximity to the equator and the Earth's elliptical orbit.

Environmental Considerations

While Pati's tropical climate is generally conducive to solar energy production, there are some environmental factors to consider:

1. Heavy rainfall during the wet season (typically November to March) may temporarily reduce solar output.
2. High humidity levels can potentially impact panel efficiency and longevity.

To mitigate these factors, installers should consider using corrosion-resistant materials and implementing proper drainage systems. Regular cleaning and maintenance of panels can also help maintain optimal performance. Additionally, investing in high-quality, weather-resistant solar equipment designed for tropical climates can ensure greater energy production and system longevity in Pati's environmental conditions.

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 Pati

Seasonal solar PV output for Latitude: -6.7559, Longitude: 111.038 (Pati, 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 7° North in Pati, Indonesia

To maximize your solar PV system's energy output in Pati, Indonesia (Lat/Long -6.7559, 111.038) throughout the year, you should tilt your panels at an angle of 7° 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 Pati, 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 Pati, Indonesia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° 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	13° North in Autumn	22° 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 Pati, 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 Pati, 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 Pati, Indonesia

The topography around Pati, Indonesia, located at latitude -6.7559 and longitude 111.038, is characterized by a diverse landscape that transitions from coastal lowlands to inland hills and mountains. Situated on the northern coast of Central Java, Pati is primarily surrounded by flat to gently rolling terrain near the shoreline. This coastal plain gradually gives way to more undulating hills as one moves inland to the south. The immediate vicinity of Pati consists of fertile alluvial plains, which have been extensively cultivated for agriculture, particularly rice paddies and other crops. These flat areas extend for several kilometers inland before the landscape begins to rise. As you move further south, the terrain becomes increasingly hilly, with elevations gradually increasing.

Nearby Mountainous Regions

To the south and southeast of Pati, the landscape becomes more rugged, with the presence of the Muria Mountains. This volcanic complex, dominated by Mount Muria, rises to an elevation of approximately 1,602 meters (5,256 feet) above sea level. The slopes of these mountains are covered in lush tropical forests and offer a stark contrast to the lowland areas closer to the coast.

Potential for Solar PV Development

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations for solar farms would be relatively flat, open areas with good sun exposure and minimal shading from natural or man-made structures. The coastal plains and gently rolling hills to the north and northeast of Pati present promising opportunities for solar PV development. These areas offer expansive, unobstructed spaces that receive ample sunlight throughout the year. The relatively flat terrain would simplify construction and reduce costs associated with land preparation. Additionally, some of the agricultural lands that are less productive or have been left fallow could be repurposed for solar farms. This approach would need to be balanced with food security concerns and local agricultural practices. It's important to note that while the hilly and mountainous regions to the south may receive good solar radiation, the challenging terrain and potential environmental impacts make these areas less suitable for large-scale solar installations. The costs associated with site preparation and the potential for increased erosion in these areas would likely outweigh the benefits. When planning solar PV projects in this region, developers would need to consider factors such as proximity to existing power infrastructure, accessibility for construction and maintenance, and potential impacts on local communities and ecosystems. Careful site selection and environmental impact assessments would be crucial to ensure the sustainability and success of any large-scale solar developments in the vicinity of Pati.
