A solar tracker is a device for orienting a solar photovoltaic panel, day lighting reflector
or concentrating solar reflector or lens toward the sun. Solar power generation works best
when pointed directly at the sun, so a solar tracker can increase the effectiveness of such
equipment over any fixed position. The solar panels must be perpendicular to the sun's rays for
maximum energy generation. Deviating from this optimum angle will decrease the efficiency of
energy generation from the panels. A few degrees of misalignment will only cause 1% to 5% of
energy loss, while larger angles of 10° to 20° will significantly decrease the energy generation of
up to 35% [4]. Although, this loss is also dependent on the material and pattern of the
protective glass that covers the solar panel.
