Madison, Mississippi, located in the Northern Sub Tropics at coordinates 32.4699, -90.1102, offers a moderately favorable location for solar PV energy generation throughout the year, with significant seasonal variations in output.

Solar energy production at this location peaks during summer months, generating an impressive 6.51kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 5.71kWh/day, while autumn yields 4.62kWh/day. Winter shows the lowest production at 2.77kWh/day per installed kilowatt.

Seasonal Performance

The substantial difference between summer and winter production (a reduction of approximately 57% from summer to winter) indicates that while Madison provides good solar potential overall, the system will experience significant seasonal fluctuations. Spring and summer (March through August) represent the prime solar harvesting period, making these months ideal for generating surplus energy that might offset lower production during fall and winter.

For optimal year-round energy capture at this location, solar panels should be installed at a 28-degree tilt facing South. This specific angle has been calculated to maximize the total annual energy production based on Madison's geographical position and seasonal solar patterns.

Environmental Considerations

Several environmental factors could potentially impact solar production in Madison. The region experiences relatively high humidity and precipitation, which can lead to cloud cover that temporarily reduces solar output. Additionally, Madison's location in the subtropical climate zone means it faces occasional severe weather, including thunderstorms and potential hurricane remnants that can bring extended periods of overcast conditions.

The area also experiences moderate tree coverage, which could create shading issues depending on the specific installation site. During spring and fall, pollen and leaf debris may accumulate on panels, potentially reducing efficiency if not addressed.

Preventative Measures

To maximize solar production in Madison, consider these preventative measures:

• Install panels in areas with minimal shade throughout the day, particularly during peak production hours
• Implement a regular cleaning schedule, especially during pollen season and after storms
• Consider micro-inverters or power optimizers to minimize the impact of partial shading
• Ensure proper drainage around ground-mounted systems to prevent flooding issues
• Use weather-resistant mounting hardware designed to withstand occasional high winds

With proper installation at the recommended 28-degree tilt angle and attention to these environmental factors, a solar PV system in Madison can provide reliable energy production, particularly excelling during the spring and summer months while still offering moderate output during fall and winter.

Solar output per kW of installed solar PV by season in Madison, Mississippi

Seasonal solar PV output for Latitude: 32.4699, Longitude: -90.1102 (Madison, Mississippi, 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 28° South in Madison, Mississippi, United States

To maximize your solar PV system's energy output in Madison, Mississippi, United States (Lat/Long 32.4699, -90.1102) throughout the year, you should tilt your panels at an angle of 28° 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 Madison, Mississippi, 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 Madison, Mississippi, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 28° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
16° South in Summer	37° South in Autumn	48° South in Winter	25° 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 Madison, Mississippi, 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 Madison, Mississippi, 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 Madison, Mississippi, United States

Madison, Mississippi, situated at approximately 32.47°N, 90.11°W, is located in the western part of the state, just north of the capital city of Jackson. The topography of Madison and its surrounding areas is characterized by gently rolling hills and flat plains typical of the Gulf Coastal Plain physiographic region.

Topographical Features

The landscape around Madison consists primarily of low, undulating terrain with elevations ranging from approximately 300 to 400 feet above sea level. This area lies within what geologists refer to as the Jackson Prairie region, which features a mix of grassland plains and wooded areas. The Pearl River and its tributaries have shaped much of the local topography, creating shallow valleys and occasional floodplains. To the east of Madison, the terrain gradually becomes more hilly as it transitions toward the North Central Hills region of Mississippi. These hills are modest in elevation but provide some topographical variation to the otherwise relatively flat landscape. The western portions of Madison County tend to be flatter, with occasional gentle slopes.

Soil and Surface Characteristics

The soil composition around Madison consists predominantly of loess (wind-deposited silt) overlying clay and sandy materials. These soils have moderate to good drainage in most areas, though some lowland sections near water features may experience periods of poor drainage during heavy rainfall. The area has significant tree cover in many places, with pine and hardwood forests interspersed throughout the region. Open agricultural lands and developed areas provide breaks in this vegetation pattern, creating a mosaic of different land cover types.

Solar PV Suitability

For large-scale solar photovoltaic (PV) installations, several factors related to the local topography make certain areas around Madison more suitable than others. The flat to gently sloping terrain found in the western portions of Madison County offers ideal conditions for solar farms, as these areas require minimal grading and site preparation. Open agricultural lands, particularly those that are currently used for row crops or are classified as fallow, present excellent opportunities for solar development due to their existing clearing and generally south-facing gentle slopes. Areas to avoid would include the floodplains of the Pearl River and its tributaries, as these locations face periodic flooding risks that could damage solar infrastructure. Similarly, the more heavily forested sections would require significant clearing, increasing both environmental impact and development costs.

Optimal Solar Locations

The most promising locations for large-scale solar PV development near Madison would be: The agricultural plains extending west and northwest of Madison, where large tracts of relatively flat, cleared land exist with good solar exposure and minimal shading concerns. These areas also tend to have reasonable proximity to existing electrical transmission infrastructure. Former agricultural lands or brownfield sites near the Madison-Ridgeland metropolitan area could also be suitable, particularly those with southerly aspects. These locations often have the advantage of being near existing power distribution networks and access roads. The slightly elevated areas of the gentle hills to the northeast of Madison may also offer good solar potential, as they can provide favorable orientation toward the sun with minimal shadowing effects from surrounding terrain features. Areas with poorer drainage or that are heavily wooded would require more extensive site preparation, making them less economically viable for solar development without significant investment in land conversion.
