Systems and Methods for Solar Energy Management

Abstract

An apparatus includes a support member having a proximal end securable to a substantially fixed surface and a distal end opposite the proximal end; a solar energy member mounted to the support member at a location between the proximal and distal ends of the support member, where the solar energy member includes a first portion and a second portion arranged such that the support member extends substantially vertically between the two portions and the two portions are rotatable about a first axis to adjust azimuth of the solar energy member and about a second axis to adjust elevation of the solar energy member; and a plurality of cables, where each cable includes a first end secured to the distal end of the support member and a second end secured to a substantially fixed position, where the cables are configured to resist a wind load acting on the apparatus.

Description

CLAIM OF PRIORITY[0001]This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application Ser. No. 61 / 444,497 filed on Feb. 18, 2011, entitled “SYSTEMS AND METHODS FOR SOLAR ENERGY MANAGEMENT,” the entire contents of which are hereby incorporated by reference.TECHNICAL BACKGROUND[0002]This disclosure relates to systems and methods for solar energy management.BACKGROUND[0003]Solar energy management, collection, and use can often help alleviate energy problems around the world. In particular, solar energy systems such as photovoltaic (“PV”) systems, which generate electrical energy from solar energy can reduce dependence on fossil fuels or other power generation techniques. Additionally, solar energy may be used to generate heat that can subsequently be used in power generation systems. In some cases, solar energy collection systems may include multiple heliostats that reflect solar energy to a receiver. The receiver may then focus the reflected solar ener...

AI Technical Summary

Benefits of technology

The patent describes an apparatus and system for managing a solar energy system. The apparatus includes a support member and a solar energy member with a reflective surface for reflecting solar rays towards a solar energy receiver. The system includes a plurality of cables that are secured to the support member and one or more fixed positions on a surface. The cables are designed to resist wind load and the system is designed to adjust the position of the solar energy member to maximize sun exposure. The technical effects of the patent include improving the efficiency of solar energy systems and reducing the cost of installation.

Problems solved by technology

Substantial wind forces on a planar object, such as a heliostat, may apply forces and torques which tend to knock the beam off-target.

One source of aiming errors of heliostats is the mechanical bending of a supporting structure under wind loads.

Often, the material and installation cost of rigid posts and secure foundations can be prohibitive to installation of a system of heliostats.

Further, the system may utilize inexpensive footings placed with minimal ground preparation and on-site installation cost as compared to expensive structural foundations of a heliostat support structure.
