Warner Linear H-Track Electric Actuators for Movable Solar Arrays
Linear actuators are routinely utilized to adjust panel angles on large solar arrays. This
movement allows the panels to be positioned toward the sun for maximum efficiency
as it moves across the sky during peak daylight hours. Movable array installations can
increase energy efficiency by up to 50 percent compared to fixed position panels. The
actuators must also be able to securely hold the panels in the desired positions since
solar arrays are often located in high wind areas.
Warner Linear has developed the new H-Track electric actuator with self-contained
hydraulic actuation to meet the demand for reliable, rugged actuators used on
solar arrays and other industrial applications. The innovative H-Track provides the
performance of hydraulics without the space requirements and expense of a full-size
H-Track actuators are able to move loads up to 4,800 lbs. (21 kN), allowing them to
handle the weight of most solar panels. A unique hydraulic valve and reservoir system
allows dual H-Track units to be installed with a connecting hose to provide smooth,
synchronized movement on larger solar panels.
Units resist drifting and hold a load stationary without power during load reversals,
allowing the H-Track to hold the panels in position in high wind environments. These
completely sealed actuators feature an anodized aluminum housing that resists
corrosion and provides protection from dirt, dust and humidity in outdoor applications.
