Bella Vista, Arkansas, located in the Northern Temperate Zone, offers a moderately favorable environment for solar PV energy generation throughout the year. The location's seasonal variations in solar output provide insights into its potential for harnessing solar energy.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 6.95 kWh per day of electricity output for each kW of installed solar capacity. Spring follows as the second-best season, generating 5.19 kWh/day. Autumn sees a decrease in production, yielding 4.41 kWh/day, while winter experiences the lowest output at 2.66 kWh/day.

These figures indicate that Bella Vista experiences significant seasonal fluctuations in solar energy production. The summer months, particularly June through August, offer the most ideal conditions for solar energy generation. Spring and early fall also provide favorable conditions, making March through May and September through October good periods for solar power production.

Optimal Panel Installation

To maximize year-round solar energy production in Bella Vista, fixed solar panels should be installed at a tilt angle of 32 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.

Environmental and Weather Considerations

While Bella Vista generally offers good conditions for solar energy production, there are some environmental and weather factors to consider:

1. Tree coverage: Bella Vista is known for its wooded areas, which could potentially shade solar panels and reduce their efficiency. Careful site selection and tree trimming may be necessary.
2. Severe weather: The region can experience thunderstorms, hail, and occasional tornadoes. Installing durable, impact-resistant panels and a robust mounting system can help mitigate potential damage.

To address these factors, it's recommended to conduct a thorough site assessment before installation. This should include a shade analysis to identify optimal panel placement. Additionally, investing in high-quality, weather-resistant solar equipment can help ensure consistent energy production and longevity of the system in Bella Vista's varied climate conditions.

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

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 4253 locations across the United States. 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 Bella Vista

Seasonal solar PV output for Latitude: 36.4691, Longitude: -94.3219 (Bella Vista, 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 32° South in Bella Vista, United States

To maximize your solar PV system's energy output in Bella Vista, United States (Lat/Long 36.4691, -94.3219) 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 Bella Vista, 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 Bella Vista, United States. 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
20° South in Summer	41° South in Autumn	52° South in Winter	30° 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 Bella Vista, 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 Bella Vista, 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 Bella Vista, United States

The topography around Bella Vista, Arkansas, located at 36.4691°N, 94.3219°W, is characterized by its position in the Ozark Mountains region. This area features a mix of rolling hills, plateaus, and valleys, creating a diverse and picturesque landscape. The terrain is generally hilly and wooded, with elevations ranging from around 900 to 1,400 feet above sea level. Bella Vista itself is situated on a plateau that is dissected by several streams and creeks, forming small valleys throughout the area. The Little Sugar Creek and its tributaries are prominent features, carving their way through the landscape and creating scenic bluffs and ravines. The surrounding forests are primarily composed of deciduous trees, with oak and hickory being predominant species.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would be relatively flat, open areas with good sun exposure and minimal shading from surrounding terrain or vegetation. The regions to the west and northwest of Bella Vista, extending into northeastern Oklahoma, offer more promising opportunities for solar PV development. These areas feature more expansive, gently rolling prairies and agricultural lands that provide larger, uninterrupted spaces suitable for solar arrays. The topography here is generally flatter, with fewer steep hills and dense forests that could obstruct sunlight or complicate installation. Additionally, areas to the south and southeast of Bella Vista, particularly as you move towards the Arkansas River Valley, may offer suitable locations for solar PV. These regions tend to have more open land and less dramatic elevation changes compared to the immediate vicinity of Bella Vista. It's important to note that while the topography around Bella Vista itself may present some challenges for large-scale solar installations due to its hilly nature and forested areas, smaller-scale or distributed solar projects could still be feasible on suitable sites within the community. Any large-scale solar development would require careful site selection, environmental impact assessments, and consideration of local zoning regulations.
