Consider location of trees
Local residents installing solar panels should consider the location of trees and whether their shade may affect the efficiency of their solar systems.
The solar panel company which installs your solar panels is responsible for providing advice on the location, orientation and other site limitations which may affect the performance of solar panels on your property.
Council does not prune a tree for the sole purpose of allowing more sunlight onto solar panels.
Before buying, ask about performance when some panels are shaded
Residents should seek as much information as possible from solar suppliers as to the performance of the entire solar panel system when a number of panels are shaded. With some systems, even partial shade can substantially affect solar generation. Don’t forget that trees grow, so take into consideration possible future shading that may occur from trees that are only in their infancy.
The efficiency of solar panels and the energy that is produced are also dependent on a number of other factors, including seasonal changes and weather conditions. In winter when the sun is lower it may cast larger shadows than in summer.
Other factors such as the quality of panels, materials and technologies, as well as how clean the panels are, will affect the optimal efficiency of the system.
Before installing solar panels, make sure all options have been considered and do as much research as possible. Solar panel systems are not a ‘one size fits all’ and there are many factors that need to be considered before making this investment.
