Quick Answer
When choosing a location for solar panels, consider the amount of direct sunlight the area receives, the presence of shading obstacles like trees or buildings, and nearby obstructions such as power lines or other electrical components.
Assessing Sunlight and Shading
When selecting a location for your solar panels, it’s essential to assess the amount of direct sunlight the area receives. Aim for a spot that receives at least 6 hours of direct sunlight per day, but ideally 8 hours for optimal performance. Consider using a solar pathfinder or a sun chart to evaluate the sunlight exposure throughout the year. Be mindful of nearby obstructions, such as trees or buildings, that could cast shadows on your panels.
Evaluating Electrical Components
When placing your solar panels, keep in mind the proximity to other electrical components like wiring, charge controllers, and batteries. Ensure that you can easily access these components for maintenance and repair. A good rule of thumb is to keep the charge controller within 10 feet of the solar panels, and the batteries within 20 feet. This will minimize voltage drop and reduce the risk of electrical fires.
Considering Roof and Ground Mounts
When deciding between a roof mount and a ground mount for your solar panels, consider the amount of space available and the local building codes. For a roof mount, ensure that the roof can support the weight of the panels and that the mounting system is rated for wind loads in your area. For a ground mount, choose a location with good drainage and consider using a solar panel racking system that can be easily adjusted to follow the sun’s movement throughout the day.
