Ideally tilt fixed solar panels 29° South in Lincoln, Alabama, United States

To maximize your solar PV system's energy output in Lincoln, Alabama, United States (Lat/Long 33.6058, -86.1106) throughout the year, you should tilt your panels at an angle of 29° 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 Lincoln, Alabama, 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 Lincoln, Alabama, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 29° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
17° South in Summer	39° South in Autumn	48° South in Winter	26° 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 Lincoln, Alabama, 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 Lincoln, Alabama, United States.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Lincoln, Alabama, United States

The topography around Lincoln, United States, located at latitude 33.6058 and longitude -86.1106, is characterized by a diverse landscape typical of the southern Appalachian region. This area, situated in eastern Alabama, features a mix of gently rolling hills, shallow valleys, and some steeper terrain as it approaches the foothills of the Appalachian Mountains to the east. The city of Lincoln itself sits in a relatively flat area, with elevations gradually increasing as one moves away from the center. To the west and southwest, the land becomes more undulating, with a series of low hills and shallow depressions. These areas are often interspersed with small streams and creeks that have carved gentle valleys over time. As one moves eastward from Lincoln, the terrain becomes more pronounced, with higher hills and steeper slopes. This area marks the transition into the Talladega Mountains, a part of the larger Appalachian chain. Here, the landscape becomes more rugged, with some areas featuring significant elevation changes and forested slopes.

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 typically include flat or gently sloping land with good sun exposure and minimal shading from surrounding terrain or vegetation. Given the topography around Lincoln, the most suitable areas for large-scale solar PV would likely be found to the west and southwest of the city. These regions feature more open, gently rolling terrain that could accommodate expansive solar arrays without requiring significant land alteration. The relatively flat nature of these areas would minimize installation costs and maximize sun exposure throughout the day. Additionally, some of the broader valley floors between the hills to the east might also offer potential sites for solar development. While these areas may be more limited in size, they could still provide suitable locations for smaller-scale solar farms. It's important to note that while the topography is a crucial factor, other considerations such as proximity to existing electrical infrastructure, land ownership, and environmental impact would also play significant roles in determining the most appropriate locations for large-scale solar PV installations in the Lincoln area.
