Solar PV Analysis of Marshfield, United States
Marshfield, Missouri, located in the Northern Temperate Zone, presents a moderately favorable location for solar PV energy generation throughout the year. The seasonal variations in solar output highlight both opportunities and challenges for solar power production in this area.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 6.83 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second-best season, generating 5.27 kWh/day. Autumn sees a noticeable decrease in output at 4.23 kWh/day, while winter experiences the lowest production at 2.60 kWh/day per kW installed.
The substantial difference between summer and winter output underscores the impact of seasonal variations on solar energy production in Marshfield. This pattern suggests that while solar PV systems can be effective year-round, they will be most efficient during the longer, sunnier days of late spring through early fall.
Optimal Panel Placement
To maximize year-round solar energy production in Marshfield, fixed solar panels should be tilted at a 33-degree angle facing south. This optimal angle takes into account the location's latitude and the sun's position throughout the year, ensuring the best possible exposure to sunlight across all seasons.
Environmental and Weather Considerations
While Marshfield's climate is generally conducive to solar energy production, there are some factors that could potentially impact solar panel efficiency:
- Snow accumulation in winter months may temporarily reduce panel output
- Occasional severe weather events, such as hailstorms or tornadoes, could pose risks to solar installations
To mitigate these challenges, consider implementing the following measures:
- Install panels at the recommended 33-degree tilt to promote snow sliding off
- Use durable, weather-resistant panels and mounting systems designed to withstand severe weather conditions
- Implement a regular cleaning and maintenance schedule to ensure optimal performance
By addressing these factors and optimizing panel placement, Marshfield residents can effectively harness solar energy throughout the year, with peak production during the summer months and satisfactory output in spring and fall.
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 Marshfield
Seasonal solar PV output for Latitude: 37.328, Longitude: -92.9276 (Marshfield, 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 33° South in Marshfield, United States
To maximize your solar PV system's energy output in Marshfield, United States (Lat/Long 37.328, -92.9276) throughout the year, you should tilt your panels at an angle of 33° 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 Marshfield, 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 Marshfield, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 21° South in Summer | 42° South in Autumn | 52° South in Winter | 31° 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 Marshfield, 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 Marshfield, 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 Marshfield, United States
The topography around Marshfield, Missouri (located at 37.328°N, 92.9276°W) is characterized by gently rolling hills and plateaus typical of the Ozark Highlands region. This area is part of the larger Ozark Plateau, which features a mix of forested hills, open grasslands, and shallow valleys carved by streams and rivers over millions of years.
The landscape surrounding Marshfield is generally undulating, with elevations ranging from about 1,300 to 1,600 feet above sea level. The terrain is not particularly steep or mountainous, but it does have a noticeable variation in elevation that creates a picturesque, rural setting. The area is dotted with small creeks and streams that flow through the gentle valleys between the hills.
For large-scale solar PV installations, the most suitable areas nearby would likely be found on the more open, flatter portions of the landscape. Ideal locations would include:
- Cleared farmland or pastures on the tops of the broader hills or plateaus, where there is less shading from surrounding terrain and vegetation.
- Gently sloping south-facing hillsides, which would receive more direct sunlight throughout the day and year.
- Areas near existing power infrastructure, such as substations or transmission lines, to minimize the cost of connecting to the grid.
- Locations with good road access for construction and maintenance purposes.
It's important to note that while the rolling terrain can provide some suitable sites for solar installations, developers would need to carefully assess each potential location for factors such as soil stability, drainage patterns, and potential environmental impacts. Additionally, they would need to consider local zoning regulations and land use policies, as well as the agricultural value of the land, before proceeding with any large-scale solar projects in the area.
United States solar PV Stats as a country
United States ranks 2nd in the world for cumulative solar PV capacity, with 95,209 total MW's of solar PV installed. This means that 3.40% of United States's total energy as a country comes from solar PV (that's 26th in the world). Each year United States is generating 289 Watts from solar PV per capita (United States ranks 15th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in United States?
Yes, there are several incentives for businesses wanting to install solar energy in the United States. These include federal tax credits, state and local rebates, net metering policies, and renewable energy certificates (RECs). Additionally, many states have enacted legislation that requires utilities to purchase a certain amount of electricity from renewable sources such as solar.
