Solar Tracker Linear Actuator, HD, 18", 12V, 750 lbs
18 lbs


WindyNation 18 inch Heavy Duty 12VDC North/South Solar Tracker Linear Actuator

Designed for lifting and lowering heavy loads. 750 lb dynamic load / 1250 lb static load.

WindyNation's 18 inch HD Linear Actuator is specifically designed to control the north/south movement on large solar trackers. This actuator is compatible with WindyNation's solar tracking electronics and most other solar tracking electronics offered on ebay (Just make sure the electronics can handle up to 12 amps of current). Limit switches are pre-installed in the actuator so you do not have to worry about the solar tracking electronics forcing the actuator to over travel. The linear actuator will stop moving after it extends 24 inches even if the solar tracking electronics tell the actuator to keep moving.

This actuator is easily capable of being used on a solar tracker with 1500 Watts of solar panels. If the solar tracker is engineered properly and wind loading calculations are performed, the actuator could be used on a solar tracker with 2500 Watts of solar panels. If you are going to use the WindyNation HD Actuator on a solar tracker, WindyNation strongly advises that you have a licensed engineer review and certify your solar tracker design.
