摘要： A method includes collecting site specific data, collecting field data at a site of an array of photovoltaic members, determining a current tracked irradiance of the array of photovoltaic members, calculating predicted irradiance for multiple orientations based on the site specific data and the sensed field data, or sensing an actual irradiance for multiple orientations. The method further includes determining a maximum predicted irradiance from the calculated predicted irradiance or a maximum actual irradiance from the sensed irradiance. The method further includes comparing the maximum predicted irradiance or the maximum sensed irradiance with the current tracked irradiance, and re-orienting the array of photovoltaic members to an orientation having the maximum predicted or actual irradiance if the maximum predicted or actual irradiance is greater than the current tracked irradiance.

摘要： Solar tracker systems having several rows of photovoltaic strings individually actuated by respective tracker control systems, are described. In an example, a solar tracker system includes a tracker control system having a tracker controller powered by forward-fed power from a photovoltaic string, e.g., during daytime, and powered by back-fed power from a station hub, e.g., during nighttime. Methods of operating the solar tracker system to forward-feed or back-feed power to the tracker control system are also described.

摘要： A multi-inverter system with at least a string of inverters sharing a DC bus and outputting to a shared AC bus. Inverters are hot-swappable and configured to be turned on or off during powered cycles. Central control may comprise reducing power point tracking redundancies or promoting other operational changes at individual inverters of a group.

摘要： Concentrating reflectors for solar energy systems can include compound curvatures producing distinct beams of light which can be aimed and shaped so as to be superimposed at a desired location, such as a plane or a solar energy receiver. Additionally, the distinct beams can have different converging characteristics producing different irradiation intensity patterns on the desired location and which when added, produce more uniform irradiation intensity distribution over the desired location.

摘要： This specification describes angled polymer solar modules, methods for producing angled polymer solar modules, and methods for installing angled polymer solar modules. In some examples, a method includes producing a flat polymer sheet including one or more photovoltaic cells. The method includes applying force to the flat polymer sheet to curve the flat polymer sheet in at least one region, forming an angled polymer sheet from the flat polymer sheet. The method includes mounting the angled polymer sheet on a roof deck such that the photovoltaic cells are angled with respect to the roof deck by virtue of the at least one region being curved.
