Chita, Aichi, Japan, located at latitude 34.991 and longitude 136.8734 in the Northern Sub Tropics, offers a promising location for solar PV energy generation throughout the year. The seasonal variations in electricity output provide insights into the potential for solar power production in this area.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 5.36 kWh per day for each kW of installed solar capacity. Spring follows closely behind, generating 5.05 kWh per day. These seasons present ideal conditions for maximizing solar energy production.

Autumn sees a moderate decrease in output, yielding 3.68 kWh per day. Winter experiences the lowest production at 3.14 kWh per day, which is still a respectable amount considering the shorter days and potential for overcast skies during this season.

Optimal Panel Installation

For fixed panel installations in Chita, Aichi, the ideal tilt angle to maximize year-round production is 32 degrees facing South. This angle takes into account the location's latitude and seasonal variations in the sun's position, ensuring optimal exposure throughout the year.

Environmental Considerations

While Chita generally offers favorable conditions for solar energy production, there are a few environmental factors to consider:

• Typhoons: Chita's coastal location makes it susceptible to typhoons, which can potentially damage solar installations.
• High humidity: The region's subtropical climate can lead to increased humidity, potentially affecting panel efficiency.

Preventative Measures

To mitigate these environmental challenges, several preventative measures can be implemented:

1. Use typhoon-resistant mounting systems and high-quality, durable panels designed to withstand strong winds and heavy rainfall.

2. Install proper drainage systems to prevent water accumulation on panels and mounting structures.

3. Implement regular cleaning and maintenance schedules to combat the effects of humidity and potential salt spray from the nearby ocean.

4. Consider using anti-reflective and hydrophobic coatings on panels to improve performance in humid conditions and facilitate self-cleaning.

By taking these precautions, solar installations in Chita can maximize their energy production potential and ensure long-term reliability despite the occasional challenging weather conditions.

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

Solar output per kW of installed solar PV by season in Chita

Seasonal solar PV output for Latitude: 34.991, Longitude: 136.8734 (Chita, Japan), 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 32° South in Chita, Japan

To maximize your solar PV system's energy output in Chita, Japan (Lat/Long 34.991, 136.8734) throughout the year, you should tilt your panels at an angle of 32° 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 Chita, 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 Chita, Japan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
19° South in Summer	41° South in Autumn	50° South in Winter	28° South 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 Chita, Japan

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 Chita, Japan.

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 Chita, Japan

The topography around Chita, Japan, located at approximately 34.991°N, 136.8734°E, is characterized by a diverse landscape that combines coastal plains, gently rolling hills, and some more elevated areas. Chita is situated on the Chita Peninsula, which juts out into Ise Bay, part of the larger Pacific Ocean. The coastal areas of Chita feature relatively flat terrain, with sandy beaches and low-lying plains extending inland for several kilometers. As one moves further from the coast, the landscape gradually transitions into undulating hills and small valleys. These hills are generally not very steep, with moderate slopes that have been shaped over time by natural erosion processes. To the east and northeast of Chita, the terrain becomes slightly more rugged, with some higher elevations and forested areas. However, these are not particularly mountainous, and the highest points in the vicinity typically do not exceed a few hundred meters above sea level.

Suitable Areas for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would combine ample sunlight exposure, relatively flat terrain, and minimal environmental or agricultural impact. The coastal plains near Chita offer promising potential for solar PV development. These areas benefit from unobstructed sunlight and have fewer competing land uses compared to more densely populated urban zones. The flat terrain would simplify construction and maintenance of solar arrays. Some of the gently sloping hillsides inland from the coast could also be suitable for solar PV installations. South-facing slopes, in particular, would receive optimal sunlight throughout the day. However, care would need to be taken to avoid areas with significant forest cover or important agricultural land. It's worth noting that while the region around Chita has potential for solar energy development, any large-scale projects would need to consider local regulations, land availability, and grid connection possibilities. Additionally, the proximity to the coast means that salt spray and potential typhoon risks would need to be factored into the design and maintenance of solar installations in this area.
