Quick Answer
Installing a second solar array away from trees can benefit off-grid systems by providing a backup source of energy in case one array is shaded by trees or other obstructions.
Understanding Shading Effects
Shading from trees and other obstructions can significantly reduce a solar array’s energy production. A single tree with a diameter of 8 feet can shade an array of 20 panels, resulting in a 30% reduction in energy output. To minimize shading effects, it’s essential to carefully plan the location of your solar array.
Benefits of a Second Array
Installing a second solar array away from trees can provide a backup source of energy in case one array is shaded. This can ensure a steady supply of electricity, even during periods of high tree growth or when cleaning the array is not feasible. A second array can also help balance the system’s energy production, reducing the impact of shading on the overall energy output.
Best Practices for Second Array Installation
When installing a second solar array, consider the following best practices: (1) orient the array at an angle of 30 degrees to maximize energy production, (2) use a separate inverter for the second array to minimize the risk of shading affecting the entire system, (3) ensure the second array is at least 10 feet away from the first array to minimize interference between the two systems. By following these guidelines, you can maximize the energy production of your second solar array and ensure a steady supply of electricity to your off-grid system.
