Patent attributes
The present invention proposes a one-axis solar tracker system and apparatus which is simple to install, lower cost and with the provision of an electric-magnetic locking device to resist from medium to strongest wind condition like hurricane or typhoon. Solar farms is more and more popular to use one-axis tracker due to lower cost, higher wind resistance and easier for large scale solar farm installation, especially at lower latitude tropic zones. This disclosure proposes a one-axis tracker with multiple posts support using a single or dual linear actuators driving mechanism for rotation. It is also equipped with a wind lock device to lock the solar tracker in horizontal neutral position during strong wind condition such as hurricane or typhoon. The stepwise wind lock device can further be applied to locking the solar tracker following each step of linear actuator activation enabling the disclosed solar tracker to operate in windy conditions.
