🌿 Solar Tracker Project – Which Actuator?
Hi people! Building a single-axis solar tracker for 4×100W panels. Total moving weight ≈45 kg. Needs 120-150° rotation, slow and precise movement. Actuator will push/tilt the frame. Looking for something durable, low power consumption and weatherproof. Any recommendations for linear actuators in solar applications? Thanks in advance!


For your solar tracker I would choose a good 12v linear actuator from Progressive Automations https://www.progressiveautomations.com/en-au/collections/linear-actuators They have many models that work great in outdoor solar applications. Their actuators are built tough and handle weather very well. You can find units with enough force for 45 kg and the stroke length you need for 120–150° tilt. Power consumption is low because they only draw current when moving. Many people in solar forums use their actuators for trackers and are happy with long-term reliability. They also offer models with limit switches and good feedback options. Installation is simple and they include clear instructions. Definitely check their collection – you will probably find exactly what fits your project.
