Hataeekikita, Fukuoka, Japan, situated in the Northern Sub Tropics at latitude 33.57 and longitude 130.2308, offers a promising location for solar PV energy generation throughout the year. The seasonal variations in electricity output provide valuable insights into the potential for solar power production in this area.

Seasonal Solar Performance

The solar PV system's performance fluctuates across the seasons, with summer and spring being the most productive periods. During summer, the system generates an impressive 5.37 kWh per day for each kW of installed capacity. Spring follows closely behind with 5.17 kWh/day. Autumn sees a moderate decrease in output, producing 4.03 kWh/day, while winter experiences the lowest generation at 3.01 kWh/day. These figures indicate that Hataeekikita enjoys favorable conditions for solar energy production throughout most of the year. The relatively high output during spring and summer makes these seasons ideal for maximizing solar energy generation.

Optimal Panel Tilt Angle

For fixed panel installations in Hataeekikita, Fukuoka, the ideal tilt angle to maximize year-round solar PV production is 30 degrees facing South. This angle has been carefully calculated to optimize energy capture across all seasons, taking into account the location's latitude and the sun's position throughout the year.

Environmental Considerations

While Hataeekikita generally offers good conditions for solar energy production, there are some environmental factors to consider: 1. Typhoons: Japan's location makes it susceptible to typhoons, which can potentially damage solar installations. 2. Heavy rainfall: The region experiences significant precipitation, which may temporarily reduce solar output. To mitigate these risks, it's crucial to implement robust installation practices:
  • Use high-quality, weather-resistant solar panels and mounting systems
  • Ensure proper drainage to prevent water accumulation on panels
  • Conduct regular maintenance to keep panels clean and functioning optimally
By addressing these factors, solar PV systems in Hataeekikita can maintain high levels of energy production throughout the year, making it an attractive location for solar energy investment.

Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 187 locations across Japan. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 30° South in Hataeekikita, Japan

To maximize your solar PV system's energy output in Hataeekikita, Japan (Lat/Long 33.57, 130.2308) throughout the year, you should tilt your panels at an angle of 30° South 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 Hataeekikita, Japan

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 Hataeekikita, Japan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 30° South tilt angle throughout the year.

Overall Best Summer Angle Overall Best Autumn Angle Overall Best Winter Angle Overall Best Spring Angle
17° South in Summer 39° South in Autumn 48° South in Winter 27° South in Spring

Assuming you can modify the tilt angle of your solar PV panels throughout the year, you can optimize your solar generation in Hataeekikita, Japan as follows: In Summer, set the angle of your panels to 17° facing South. In Autumn, tilt panels to 39° facing South for maximum generation. During Winter, adjust your solar panels to a 48° angle towards the South for optimal energy production. Lastly, in Spring, position your panels at a 27° angle facing South to capture the most solar energy in Hataeekikita, Japan.

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 Hataeekikita, Japan

Topography for solar PV around Hataeekikita, Japan

The area around Hataeekikita, Japan, located at approximately 33.57°N latitude and 130.2308°E longitude, is characterized by a diverse topography typical of many coastal regions in Japan. This location is situated on the island of Kyushu, in Fukuoka Prefecture.

The landscape in this region is a mix of coastal plains, rolling hills, and low mountains. Near the coast, you'll find relatively flat areas that gradually rise into gently sloping terrain as you move inland. These coastal plains are often used for agriculture and urban development. As you progress further from the coast, the terrain becomes more undulating, with hills and small valleys creating a patchwork of different elevations.

Moving inland, the topography becomes more mountainous, with steeper slopes and higher elevations. These areas are often covered in forests and may have terraced hillsides used for agriculture in some places. The region also features river valleys that cut through the landscape, creating natural corridors and flatter areas amidst the more rugged terrain.

Regarding areas suitable for large-scale solar PV (photovoltaic) installations, the most promising locations would likely be found in the following areas:

1. Coastal plains: These flat or gently sloping areas near the coast offer ample space and good sun exposure. However, they may face competition from agricultural and urban uses.

2. Elevated plateaus: If present in the region, these relatively flat areas at higher elevations could provide excellent locations for solar farms, as they often have less competing land use and good sun exposure.

3. South-facing hillsides: Gentle to moderate slopes facing south would receive optimal sunlight throughout the day, making them potentially suitable for solar installations.

4. Abandoned or underutilized agricultural land: Areas that are no longer actively farmed could be repurposed for solar energy production, especially if they are relatively flat and have good sun exposure.

It's important to note that while topography is a crucial factor in determining suitable locations for solar PV installations, other considerations such as proximity to power infrastructure, local regulations, and environmental impact must also be taken into account. Additionally, given Japan's commitment to renewable energy, there may already be existing solar projects in the area, which could influence the availability of suitable sites for new large-scale installations.
