Solar trackers are prevalent on the market currently to increase efficiency as panel costs are flat lining. While trackers can increase the output of a panel by up to 40%, they are quite expensive and require maintenance due to the addition of batteries, motors, and extra wiring. While these are expensive, there is space to create solar trackers that are more accurate at a lower cost or don`t use any electrical components to reduce upkeep and cost. Passive trackers are gaining traction but many suffer from having low efficiency increases and difficulty with installation. Solar trackers are clearly the future with over 90% of current solar installations having trackers installed but they still suffer from high up-front costs and maintenance.
