Quick Answer
For optimal solar panel placement, consider a roof-mounted system if the roof faces 90-180 degrees south and receives minimal shading. Ground-mounted systems are better suited for areas with steep slopes, limited roof space, or south-facing backyards. A combination of both can also be effective.
Choosing Between Roof and Ground Mounts
When deciding between a roof or ground mount for solar panels, consider the roof’s orientation and shading. A south-facing roof with minimal shading is ideal for solar panels, as it captures the most direct sunlight throughout the day. A 90-180 degree south-facing roof can produce around 25-40% more electricity than a north-facing roof. For ground mounts, ensure the panels are at least 3-4 feet above the ground to allow for easy cleaning and maintenance.
Factors to Consider for Ground Mounts
Ground mounts are a better option for areas with steep slopes or limited roof space. They also provide easier access for cleaning and maintenance, as panels can be walked under for cleaning. For ground mounts, use a tracking system to optimize energy production, which can increase energy output by 20-30%. A single-axis tracker can be used for ground mounts, which can produce up to 45% more energy than a fixed ground mount.
