Solar trackers and control systems prevent damage from weather events – such as hail – by orienting solar panels at optimal angles during such weather events. These angles may be achieved and managed by the physical stops of the slew drives and mechanical stop assemblies in the tracker. Control systems may trigger stowing of the solar panels during such weather events in a variety of ways, including comparing irradiance measured from the solar panels with expected irradiance.

The invention relates to a photovoltaic panel comprising a microlens layer applied to the front surface of photovoltaic cells by one of various possible methods, including spray coating, together with a base layer. This microlens layer functions as a micro-concentrator of light, improving radiation absorption, particularly at high angles of incidence. The panel is characterized by the presence of an optical space above the microlenses, free from materials with high refractive indices, enabling effective focusing of sunlight. The solution provides for the simultaneous application of the base layer and microlenses onto multiple cells within the module using manipulators. The protective cover is structurally connected to the edges of the cells, allowing the central surface to remain free from optical disturbances. The invention does not concern the geometry of the microlenses or their forming method, but rather a new photovoltaic panel architecture integrating a known microlens coating within a novel structural configuration.
