Willard, Ohio presents a moderately favorable location for solar energy generation, though it faces typical challenges common to the Northern Temperate Zone climate of the Midwest United States.
Seasonal Solar Performance
The solar energy output at this location varies significantly throughout the year. Summer provides the strongest performance at 6.09 kWh per day per kW of installed solar capacity, making it the peak season for energy generation. Spring follows as the second-best performing season with 5.43 kWh per day per kW, offering nearly comparable output to summer months. Autumn sees a notable decline in solar production, dropping to 3.36 kWh per day per kW as daylight hours decrease and weather patterns shift. Winter presents the most challenging conditions for solar generation, with output falling to just 1.75 kWh per day per kW of installed capacity. For optimal year-round energy production from a fixed panel installation at this location, solar panels should be tilted at 35 degrees facing south. This angle maximizes the total annual solar output by accounting for the sun's varying position throughout the seasons.Local Factors Affecting Solar Production
Several environmental and weather factors in Willard, Ohio can significantly impact solar energy generation:- Snow accumulation: Heavy winter snowfall can completely block solar panels, eliminating energy production until the snow melts or is removed
- Frequent cloud cover: The region experiences considerable overcast conditions, particularly during autumn and winter months, which reduces solar irradiance
- Ice formation: Freezing rain and ice storms can coat panels, blocking sunlight and potentially damaging equipment
- Atmospheric haze and humidity: Summer humidity and seasonal haze can reduce the clarity of sunlight reaching the panels
Preventative Measures for Better Performance
Several installation strategies can help mitigate these local challenges:- Steeper tilt angles: Installing panels at angles steeper than the optimal 35 degrees can help snow slide off more easily, though this may slightly reduce overall annual production
- Anti-reflective coatings: Specialized panel coatings can improve light absorption during hazy or overcast conditions
- Proper spacing: Adequate spacing between panel rows prevents snow buildup and allows for easier maintenance access
- Quality mounting systems: Robust mounting hardware designed for ice and snow loads ensures system durability through harsh winter conditions
- Regular maintenance scheduling: Planning for seasonal cleaning and snow removal helps maintain consistent energy production
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 Willard
Seasonal solar PV output for Latitude: 41.0659, Longitude: -82.7296 (Willard, 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 35° South in Willard, United States
To maximize your solar PV system's energy output in Willard, United States (Lat/Long 41.0659, -82.7296) throughout the year, you should tilt your panels at an angle of 35° 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 Willard, 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 Willard, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 25° South in Summer | 45° South in Autumn | 55° South in Winter | 34° 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 Willard, 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 Willard, United States.
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 Willard, United States
Topographic Features Around Willard, Ohio
The area surrounding Willard, Ohio is characterized by gently rolling terrain typical of north-central Ohio's glaciated landscape. This region sits within the Till Plains physiographic province, where ancient glacial activity has created a relatively flat to gently undulating topography with elevations ranging from approximately 900 to 1,100 feet above sea level. The landscape features broad, shallow valleys separated by low ridges and hills, creating a pattern of gentle slopes that rarely exceed 10-15 degrees.
Agricultural fields dominate the immediate vicinity, interspersed with woodlots and small streams that drain northward toward Lake Erie. The terrain becomes slightly more varied to the south and east, where the influence of the Allegheny Plateau begins to assert itself through more pronounced hills and deeper valleys. To the north and west, the land becomes progressively flatter as it approaches the Lake Erie plain.
The soil composition consists primarily of glacial till and outwash deposits, creating well-drained to moderately well-drained conditions across most of the area. Small wetlands and seasonal ponds occasionally dot the landscape in lower-lying areas where drainage is more restricted.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations lie in the open agricultural areas immediately surrounding Willard, particularly to the northwest, west, and southwest of the community. These areas offer several key advantages including relatively flat terrain that minimizes grading requirements and reduces installation costs, while providing excellent southern exposure across large contiguous parcels.
The gently sloping farmland west of Willard presents particularly favorable conditions, with south-facing slopes that provide natural tilt optimization and minimal shading concerns. These areas benefit from being largely free of tall vegetation or structures that could create shadows, while the existing agricultural use suggests soil conditions stable enough to support solar mounting systems.
Areas to the northwest offer extensive flat terrain with minimal topographic obstacles, making them well-suited for utility-scale solar farms that require large, relatively uniform installation surfaces. The agricultural nature of this land means it typically has good access to existing electrical infrastructure along rural roads, which can reduce interconnection costs.
The region southeast of Willard, while slightly more varied topographically, still contains numerous suitable sites on south-facing slopes and plateau areas. These locations benefit from natural drainage patterns that help prevent water accumulation around solar installations while maintaining the gentle grades preferred for large-scale development.
Areas with steeper slopes, particularly those facing north or heavily shaded by existing tree cover, would be less optimal for solar development. Similarly, the small wetland areas scattered throughout the region and the immediate floodplains of local streams would present regulatory and practical challenges for solar installation.
United States solar PV Stats as a country
