Graph of hourly avg kWh electricity output per kW of Solar PV installed in Watford City, United States (by season)

Watford City, North Dakota, located in the Northern Temperate Zone, presents a mixed opportunity for solar PV energy generation. The location experiences significant seasonal variations in solar energy production, which impacts its overall suitability for year-round solar power generation.

Seasonal Solar Production

Solar energy production in Watford City varies dramatically throughout the year. Summer months offer the highest potential, with an average of 6.81 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second most productive season, generating 5.46 kWh/day. However, autumn and winter see a substantial decrease in production, with 3.34 kWh/day and 1.85 kWh/day, respectively.

Optimal Times for Solar Generation

The most ideal period for solar energy production in Watford City is from late spring through early fall. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. Summer solstice, typically around June 21st, marks the peak of solar potential in this region.

Panel Installation Considerations

For fixed panel installations in Watford City, the optimal tilt angle to maximize year-round production is 41 degrees facing south. This angle helps balance energy capture across seasons, particularly enhancing winter production when the sun's path is lower in the sky.

Environmental and Weather Factors

Several factors can impede solar production in Watford City:

  • Harsh winters with heavy snowfall can cover panels, reducing efficiency
  • Short winter days significantly limit production during colder months

To mitigate these challenges, consider installing panels at a steeper angle to encourage snow sliding off. Additionally, using snow-shedding coatings on panels and implementing a regular cleaning schedule can help maintain production levels during winter months.

While Watford City's location presents challenges for year-round solar energy production, proper planning and installation techniques can help maximize the potential of solar PV systems in this area. The substantial summer production can partially offset the reduced winter output, making solar a viable, though seasonally variable, energy option.

Ideally tilt fixed solar panels 41° South in Watford City, United States

To maximize your solar PV system's energy output in Watford City, United States (Lat/Long 47.8148, -103.2511) throughout the year, you should tilt your panels at an angle of 41° 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.

At Latitude: 47.8148, Longitude: -103.2511, the ideal angle to tilt panels is 41° South

Seasonally adjusted solar panel tilt angles for Watford 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 Watford City, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 41° South tilt angle throughout the year.

Overall Best Summer Angle Overall Best Autumn Angle Overall Best Winter Angle Overall Best Spring Angle
31° South in Summer 51° South in Autumn 62° South in Winter 40° South in Spring

Assuming you can modify the tilt angle of your solar PV panels throughout the year, you can optimize your solar generation in Watford City, United States as follows: In Summer, set the angle of your panels to 31° facing South. In Autumn, tilt panels to 51° facing South for maximum generation. During Winter, adjust your solar panels to a 62° angle towards the South for optimal energy production. Lastly, in Spring, position your panels at a 40° angle facing South to capture the most solar energy in Watford City, United States.

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 Watford City, United States

Topography for solar PV around Watford City, United States

The topography around Watford City, North Dakota, is characterized by rolling hills and prairies typical of the Great Plains region. This area is part of the Missouri Plateau, which features a mix of flat to gently undulating terrain interspersed with more rugged badlands formations. The landscape has been shaped by glacial activity and erosion over millions of years, resulting in a diverse topography that includes broad valleys, steep buttes, and winding rivers.

The city itself sits at an elevation of about 2,100 feet above sea level. As you move away from Watford City, you'll encounter varying elevations, with some nearby hills reaching heights of 2,500 feet or more. The surrounding countryside is dotted with coulees (deep ravines) and draws (smaller valleys), which add texture to the otherwise relatively flat prairie landscape.

To the south and east of Watford City, the terrain becomes more rugged as it transitions into the badlands of Theodore Roosevelt National Park. This area features dramatic rock formations, colorful striations in the hillsides, and deeply eroded canyons.

Regarding areas suitable for large-scale solar PV installations, the most promising locations would be found on the flatter, more open prairie lands surrounding Watford City. Ideal sites would be gently sloping or flat areas with good southern exposure, minimal shading from nearby landforms, and easy access to existing infrastructure.

The areas to the north and west of Watford City, where the terrain tends to be less rugged, might offer the best opportunities for solar development. These regions typically have fewer steep slopes and more consistent, open spaces that could accommodate large arrays of solar panels. Additionally, the relatively high elevation of the Missouri Plateau means these areas receive ample sunlight throughout the year, making them potentially productive for solar energy generation.

However, it's important to note that any large-scale solar project would need to consider factors beyond just topography, such as proximity to transmission lines, local zoning regulations, and environmental impact assessments. The presence of oil and gas development in the region may also influence the availability of suitable land for solar installations.
