System and method for installing heliostats

A mounting system for a heliostat is provided that allows the heliostat to move relative to two orthogonal axes to track the sun. The mounting system has features that allow heliostats to precisely move about these axes even in harsh environments and in the event of degradation of various components during long-term operation. Embodiments of the mounting system may have a frame that supports a plurality of mirrors and transfers forces from the mirrors to a plurality of hubs that move about a circular orbit. One of the hubs may include a smaller number of contact points to accommodate a less circular orbit. Further, an actuator that moves the hub around the circular track may be biased into the track to accommodate a less circular track. 提供了一种用于定日镜的安装系统，该安装系统允许定日镜相对于两个正交轴线运动以追踪太阳。所述安装系统具有即使在恶劣环境中和长时间运行期间各种部件劣化的情况下也允许定日镜精准地围绕这些轴线运动的特征。所述安装系统的实施例可以具有框架，该框架支撑多个反射镜并将来自反射镜的力传递至围绕圆形轨道运动的多个轮毂。所述轮毂之一可以包括较少数量的接触点，以适应不太圆的圆形轨道。此外，围绕圆形轨道移动轮毂的致动器可以被偏压到轨道中，以适应不太圆的圆形轨道。
