The location of Bethel, Ohio in the United States offers a moderate potential for solar energy generation throughout the year. Situated in the Northern Temperate Zone, this area experiences distinct seasonal variations in solar output.

Seasonal Solar Performance

Summer stands out as the most productive season for solar energy in Bethel, with an average daily output of 6.22 kWh per kW of installed solar capacity. This high performance is due to longer daylight hours and more direct sunlight. Spring follows closely behind, generating an average of 5.52 kWh per day. This season benefits from increasing daylight and generally clearer skies. Autumn sees a noticeable decrease in solar production, with an average of 3.87 kWh per day. This reduction is primarily due to shorter days and the sun's lower position in the sky. Winter presents the greatest challenge for solar energy generation in Bethel, with output dropping to 2.17 kWh per day. Shorter days, lower sun angles, and potential snow cover contribute to this reduced performance.

Optimal Panel Positioning

To maximize year-round solar energy production in Bethel, fixed solar panels should be tilted at a 34-degree angle facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun positions across seasons.

Environmental Considerations

While Bethel's location is generally favorable for solar energy, there are some environmental factors to consider: 1. Snow accumulation in winter can temporarily reduce panel efficiency. 2. Cloudy days, particularly common in autumn and winter, can impact solar output. To mitigate these issues, consider the following preventative measures: - Install panels at a steeper angle to promote snow shedding - Use anti-reflective coatings to improve performance in low-light conditions - Implement a regular cleaning schedule to remove debris and snow By addressing these factors, solar installations in Bethel can maximize their energy production potential throughout the year.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Bethel, Ohio

Seasonal solar PV output for Latitude: 38.9637, Longitude: -84.0808 (Bethel, Ohio, United States), 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 34° South in Bethel, Ohio, United States

To maximize your solar PV system's energy output in Bethel, Ohio, United States (Lat/Long 38.9637, -84.0808) throughout the year, you should tilt your panels at an angle of 34° 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 Bethel, Ohio, United States

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 Bethel, Ohio, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
23° South in Summer	43° South in Autumn	54° South in Winter	32° 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 Bethel, Ohio, United States

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 Bethel, Ohio, United States.

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 Bethel, Ohio, United States

The topography around Bethel, United States, located at latitude 38.9637 and longitude -84.0808, is characterized by gently rolling hills and shallow valleys typical of the Midwest region. This area, situated in southwestern Ohio, is part of the broader Interior Low Plateaus physiographic region. The landscape is a mix of farmland, wooded areas, and small streams that wind through the countryside. The terrain in and around Bethel is relatively mild, with modest elevation changes. The hills are generally low and rounded, having been shaped by glacial activity during the last ice age. This has resulted in a landscape that is neither flat nor dramatically steep, but rather a series of gentle undulations. The area's elevation typically ranges from about 800 to 1000 feet above sea level, with local variations creating a patchwork of small hills and shallow depressions.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The gently rolling terrain in the region around Bethel offers some advantages for solar development. Areas with slight southern-facing slopes would be particularly well-suited, as they would receive more direct sunlight throughout the day. Open farmland in the vicinity of Bethel could be ideal for solar PV projects. These areas often have large, unobstructed spaces that receive ample sunlight. Additionally, they typically have existing road access, which is beneficial for construction and maintenance of solar facilities. However, it's important to note that the region's climate, with its mix of sunny and cloudy days, as well as potential for snow in winter, may impact the overall efficiency of solar installations. Developers would need to carefully assess specific sites for their solar potential, taking into account factors such as local shading from trees or buildings, soil stability, and proximity to electrical infrastructure. While the topography around Bethel is generally favorable for solar PV, large-scale projects would require detailed site-specific assessments to determine the most optimal locations. These assessments would consider not only the physical landscape but also environmental impacts, local zoning regulations, and community considerations.
