Solar PV Analysis of Central City, United States
Central City, Nebraska, located in the Northern Temperate Zone of the United States, presents a mixed picture for solar energy generation throughout the year. With its position at 41.1221° N latitude and -98.0018° W longitude, this location experiences significant seasonal variations in solar energy production.
Seasonal Solar Performance
Solar energy output in Central City peaks during the summer months, with an impressive 7.23 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second-most productive season, generating 5.48 kWh/day. However, autumn and winter see a considerable drop in energy production, with 3.85 kWh/day and 2.79 kWh/day respectively.
The stark contrast between summer and winter production highlights the challenges of year-round solar energy generation in this region. While summer offers excellent conditions for solar power, the shorter days and lower sun angle in winter significantly reduce energy output.
Optimal Panel Positioning
To maximize year-round solar energy production in Central City, fixed solar panels should be tilted at a 36-degree angle facing south. This optimal angle helps balance energy capture across all seasons, compensating for the sun's changing position throughout the year.
Environmental and Weather Considerations
Central City's location in the Great Plains region exposes it to some environmental factors that could affect solar production:
- Snow accumulation in winter can temporarily reduce panel efficiency
- Dust and pollen during dry periods may coat panels, slightly decreasing their effectiveness
To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off and implement a regular cleaning schedule. Additionally, using micro-inverters or power optimizers can help maintain overall system performance when individual panels are affected by shading or debris.
Conclusion
While not ideal year-round, Central City offers good potential for solar energy generation, particularly from late spring through early fall. The significant seasonal variations mean that supplementary energy sources or storage solutions may be necessary to maintain consistent power supply throughout the year. Despite the challenges, with proper planning and installation techniques, solar PV systems can still be a valuable and effective energy solution for this Nebraska location.
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 Central City
Seasonal solar PV output for Latitude: 41.1221, Longitude: -98.0018 (Central City, 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 36° South in Central City, United States
To maximize your solar PV system's energy output in Central City, United States (Lat/Long 41.1221, -98.0018) throughout the year, you should tilt your panels at an angle of 36° 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 Central City, 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 Central City, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 36° 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 Central City, 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 Central City, 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 Central City, United States
The area around Central City, Nebraska (located at 41.1221°N, 98.0018°W) is characterized by a relatively flat topography typical of the Great Plains region. This part of Nebraska is known for its gently rolling prairies and expansive agricultural lands. The landscape is predominantly level to slightly undulating, with occasional shallow depressions and low hills.
The Platte River, a major waterway in Nebraska, flows to the south of Central City, creating a shallow valley with some minor elevation changes near its banks. However, the overall terrain remains fairly consistent, with minimal dramatic shifts in elevation across the surrounding area.
As for areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, several factors make the region around Central City potentially favorable:
1. The flat terrain is ideal for solar farms, as it requires minimal land preparation and allows for easy installation of solar panels over large areas.
2. The open, rural nature of the landscape means there are fewer obstructions that could cast shadows on solar panels, maximizing their exposure to sunlight throughout the day.
3. Agricultural lands that are less productive or fallow could be repurposed for solar energy production, providing an alternative use for the land without significantly impacting prime farmland.
Specific areas to consider for large-scale solar PV installations might include:
- Open fields to the north and east of Central City, where the land is particularly flat and unobstructed.
- Areas slightly elevated from the Platte River valley, which would be less prone to potential flooding while still maintaining the desired flat topography.
- Regions along major roads or near existing power infrastructure, which could facilitate easier connection to the electrical grid.
It's important to note that while the topography is generally suitable, other factors such as local zoning laws, environmental considerations, and proximity to transmission lines would also need to be taken into account when selecting specific sites for solar PV development.
