Quick Answer
Better solar energy collection can be achieved with tracking systems, which can increase energy production by up to 45% compared to fixed solar panels. These systems follow the sun's movement to optimize the angle of the solar panels, maximizing exposure to sunlight throughout the day.
Types of Tracking Systems
There are two primary types of solar tracking systems: single-axis and dual-axis. Single-axis trackers move the panels in one plane, following the sun’s east-west movement, and can increase energy production by up to 30%. Dual-axis trackers, on the other hand, move the panels in two planes, following the sun’s east-west and north-south movement, and can increase energy production by up to 45%. These systems are more complex and expensive to install, but offer higher energy gains.
Optimizing Solar Panel Tilt Angle
For optimal solar panel tilt angle, consider the latitude and climate of your location. In areas with high solar radiation, a steeper tilt angle (between 30° and 40°) can maximize energy production. In areas with low solar radiation, a shallower tilt angle (between 20° and 30°) can help reduce snow accumulation and improve winter performance. It’s essential to balance the trade-offs between energy production and snow load considerations when determining the optimal tilt angle.
