Horizontal single-row solar trackers can deliver higher value at lower cost by increasing the available options regarding tracker length. The ability to drive up to 240 square meters of modules from a single, reliable drive and controller can reduce tracker cost, installation cost, and operations and maintenance cost, and can increase Ground Coverage Ratio (GCR) – the ratio of module area to site area.
While costs are reduced, some challenges are introduced, including the ability to follow terrain, and the ability to track the sun accurately. These challenges and their solutions are discussed below. OMCO Origin Trackers achieve low total system cost and high GCR by enabling mounting of up to 120 standard 2 meter x 1 meter crystalline silicon modules per tracker.
