Problems solved by technology

[0005] However, the traditional solar tracker has some disadvantages: 1. In addition to supporting the entire weight of the solar panel, the rotary drive must also bear the lateral force and moment generated by the fixed tilt of the solar panel, and bear the wind load on the solar panel (wind load)
As a result, the slewing drive becomes very bulky
3. If there is a problem with the rotary drive and must be repaired or replaced, the entire solar panel must be disassembled before proceeding
4. Due to the lifting mechanism provided by the linear drive to a single solar panel, the center of gravity of the solar panel often changes relative to the pivoting point of the rotary drive, which may force the rotary drive to bear the maximum moment of
But this makes the traditional two-axis solar tracker very bulky and expensive

Abstract

The present invention relates to a simplified and lower cost two-axes tracker for solar PV (photovoltaic) or CPV (concentrated photovoltaic) solar panel, as well as heliostat solar reflectors and solar Stirling engine. In particular, the disclosure addresses a simplified and gravity centered tracker structure with low cost single or dual linear actuators mounted on the side of ground post which is easier for replacement and maintenance at lower cost.

Description

technical field [0001] The present invention relates to a dual-axis solar tracker with simplified structure and low cost, which is used on solar photovoltaic (photovoltaic, PV) panels and solar concentrated photovoltaic (CPV) panels, and is used for reflective concentrating sunlight systems. On the solar concentrator and Stirling engine (Stirling engine) reflective dish. The present invention particularly relates to a gravity-centered tracking structure with a simplified structure. The tracking structure includes a single or two low-cost linear actuators, and the linear actuators are installed on one side of a ground post. Lower cost for replacement and repair. Background technique [0002] Solar photovoltaic panels are gradually becoming standard equipment on the roofs of general residential areas. The amount of solar energy irradiated to the solar panel on the roof depends on the sine value (sine) of the elevation angle formed between the sun and the solar panel. In oth...
