Solar Energy Potential in Zanesville, Ohio
Zanesville, Ohio, located at latitude 39.9275 and longitude -82.0032 in the Northern Temperate Zone, presents a mixed picture for solar energy generation throughout the year. The location experiences significant seasonal variations in solar output, which impacts the overall efficiency of solar PV systems. During summer, Zanesville enjoys its peak solar production, with an average daily output of 6.16 kWh per kW of installed solar capacity. This makes it an excellent time for solar energy generation, with long days and abundant sunshine. Spring follows closely behind, with a respectable 5.46 kWh/day, offering good potential for solar power as days lengthen and skies clear. However, the colder months see a substantial drop in solar production. Autumn yields a moderate 3.61 kWh/day, while winter experiences a significant decline to just 1.95 kWh/day per kW installed. This stark contrast highlights the challenges of relying solely on solar power in Zanesville throughout the year.Optimizing Solar Panel Installation
To maximize year-round solar energy production in Zanesville, fixed solar panels should be installed at a tilt angle of 34 degrees facing south. This optimal angle helps capture the most sunlight across all seasons, balancing the high summer sun with the lower winter sun angle.Environmental and Weather Considerations
Several factors can impact solar production in Zanesville: 1. Cloud cover: Ohio experiences significant cloud cover, especially during winter months, which can reduce solar output. 2. Snow accumulation: Winter snowfall can temporarily cover panels, impeding energy production. 3. Humidity: High humidity levels, common in Ohio summers, can slightly reduce panel efficiency. To mitigate these issues, consider the following preventative measures:- Install panels at the optimal angle to help shed snow and maximize exposure to winter sun.
- Use anti-reflective coatings on panels to improve performance in low-light conditions.
- Implement a regular cleaning schedule to remove snow and debris.
- Consider micro-inverters or power optimizers to minimize the impact of partial shading.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 34° South in Zanesville, United States
To maximize your solar PV system's energy output in Zanesville, United States (Lat/Long 39.9275, -82.0032) 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 Zanesville, 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 Zanesville, 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 |
|---|---|---|---|
| 24° South in Summer | 44° South in Autumn | 55° South in Winter | 33° 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.

Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Zanesville, United States
The topography around Zanesville, Ohio, located at approximately 39.9275°N, 82.0032°W, is characterized by gently rolling hills and valleys typical of the Appalachian Plateau region. This area, situated in east-central Ohio, features a diverse landscape shaped by ancient glacial activity and subsequent erosion. The terrain surrounding Zanesville is marked by a series of low hills and ridges interspersed with shallow valleys and small streams. The Muskingum River, which flows through the heart of Zanesville, has carved a wider valley that bisects the region. This river and its tributaries have played a significant role in shaping the local topography over millions of years. The elevation in the Zanesville area generally ranges from about 700 to 1,000 feet above sea level. The highest points are typically found on the hilltops and ridges, while the lowest elevations occur along the river valleys and floodplains. This variation in elevation creates a picturesque landscape with scenic vistas and diverse ecosystems.
Potential 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 for solar farms in the vicinity of Zanesville would likely be: South-facing slopes: The gentle hills in the region offer opportunities for solar panels to be installed on south-facing slopes, which receive more direct sunlight throughout the day. These areas would maximize solar energy capture and efficiency. Open agricultural land: The surrounding rural areas, particularly those with expansive farmland, could be suitable for solar PV installations. These locations often provide large, unobstructed spaces that are relatively flat and easy to develop. Abandoned industrial sites: Zanesville and nearby communities may have former industrial or mining areas that could be repurposed for solar energy production. These brownfield sites are often already cleared and may have existing infrastructure that can be utilized. Areas near existing power infrastructure: Locations close to power substations or transmission lines would be advantageous for connecting large-scale solar installations to the grid, reducing the need for extensive new infrastructure. It's important to note that while the topography around Zanesville is generally favorable for solar PV, specific site assessments would be necessary to determine the most suitable locations. Factors such as local zoning regulations, environmental considerations, and community support would also play crucial roles in the development of large-scale solar projects in the area.United States solar PV Stats as a country
