Solar Energy Potential in Norcross, Georgia

Norcross, Georgia, located in the Northern Sub Tropics at latitude 33.9395 and longitude -84.2008, offers a favorable environment for solar energy production throughout the year. The location experiences varying levels of solar energy generation across different seasons, with summer and spring being the most productive periods.

Seasonal Solar Output

Solar panels in Norcross can expect to generate an average of 6.21 kWh per day for each kilowatt of installed capacity during summer months. This high output is due to longer daylight hours and more direct sunlight. Spring follows closely behind, with an average daily output of 6.06 kWh per kilowatt installed. Autumn sees a moderate decrease in solar energy production, with an average of 4.54 kWh per day for each kilowatt of installed capacity. Winter experiences the lowest output, averaging 2.84 kWh per day per kilowatt installed, due to shorter days and less direct sunlight.

Optimal Panel Tilt

For fixed panel installations in Norcross, the ideal angle to maximize year-round solar energy production is 30 degrees tilted towards the South. This angle helps optimize sunlight capture throughout the year, balancing the sun's changing position across seasons.

Environmental Factors and Mitigation

While Norcross generally offers good conditions for solar energy production, there are some environmental factors to consider: 1. Tree coverage: Norcross has a significant number of trees, which could potentially shade solar panels. To mitigate this, careful site assessment and strategic panel placement are crucial. 2. Humidity: The area's subtropical climate can lead to high humidity levels, which may slightly reduce panel efficiency. Regular cleaning and maintenance can help counteract this effect. 3. Occasional severe weather: Georgia can experience thunderstorms and occasional hurricanes. Installing sturdy mounting systems and using high-quality, weather-resistant panels can help protect the solar installation during extreme weather events. By addressing these factors during the installation process, solar energy systems in Norcross can achieve optimal performance and longevity, making the most of the area's generally favorable conditions for solar power generation.

Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Ideally tilt fixed solar panels 30° South in Norcross, United States

To maximize your solar PV system's energy output in Norcross, United States (Lat/Long 33.9395, -84.2008) throughout the year, you should tilt your panels at an angle of 30° 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 Norcross, 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 Norcross, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 30° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
18° South in Summer	39° South in Autumn	49° 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 Norcross, 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 Norcross, 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 Norcross, United States

The area around Norcross, Georgia, located at 33.9395°N and 84.2008°W, is characterized by gently rolling hills and a mix of urban and suburban landscapes. This region, part of the Atlanta metropolitan area, sits in the Piedmont plateau, which extends from the Appalachian Mountains to the coastal plain. The topography of Norcross and its surroundings features modest elevation changes, with hills and valleys creating a subtly undulating terrain. The area's elevation generally ranges from about 900 to 1,100 feet above sea level. This landscape is dotted with numerous creeks and small water bodies, including ponds and lakes, which contribute to the region's drainage system.

Vegetation and Land Use

The natural vegetation in the Norcross area consists of mixed deciduous and evergreen forests, typical of the southeastern United States. However, much of the original forest cover has been altered due to urban development. The landscape is now a patchwork of residential neighborhoods, commercial areas, parks, and remnant woodlands.

Potential for Solar PV Installation

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The gently rolling terrain of the region generally provides good opportunities for solar development, but some specific considerations should be taken into account: Open spaces to the east and southeast of Norcross, particularly in less densely populated areas of Gwinnett County, might offer suitable locations for solar farms. These areas tend to have more available land and potentially fewer obstacles that could cast shadows on solar panels. Former agricultural lands or brownfield sites in the surrounding counties could be ideal for solar PV installations. These areas often provide large, open spaces with minimal shading from trees or buildings. The relatively flat terrain of industrial parks or large commercial zones in the greater Atlanta area could also be suitable for rooftop solar installations on a significant scale. It's important to note that while the topography is generally favorable, the abundance of trees in the region might pose challenges in some locations. Careful site selection and potentially some land clearing would be necessary to maximize solar exposure. Additionally, areas near existing electrical infrastructure would be advantageous for connecting large-scale solar installations to the grid. Proximity to major power lines and substations should be considered when identifying the most suitable locations for solar PV projects in the region around Norcross.
