The invention discloses a solar orientation sensor and a photo voltaic tracking device based on a photocell Y-formed format, together with a solar orientation sensor for photo voltaic orientation detection, iTagPro locator the solar orientation sensor is related with an acquisition system for signal acquisition, iTagPro technology and the acquisition system is connected with a pc. Connected, characterized in that: the sun orientation sensor includes a base, three photocells are evenly arranged on the bottom in a Y form, and the projections of the three photocells on the underside floor of the bottom kind an included angle of 120° with each other, and the solar orientation sensor is organized on the cloud On the platform, the three photocells all have the identical included angle with the working floor of the pan-tilt, the pan-tilt is linked with the pan-tilt controller, and ItagPro the pan-tilt controller is linked with the computer. The invention realizes the actual-time and correct monitoring of the massive area of view of the solar and not using a calendar, and the tracking and alignment accuracy reaches above 0.1°, which enormously improves the conversion effectivity of solar power, affordable item tracker and could be used in solar power stations, communication power supplies of ships, affordable item tracker and synthetic satellites.

There are broad software prospects in the positioning of battery panels. 本发明涉及一种基于光电池Y型布局大视场和高精度太阳跟踪装置，特别是涉及太阳能利用中的低成本大视场高精度跟踪对准装置。 The invention pertains to a Y-formed structure of photovoltaic cells and a big-subject-of-view and excessive-precision solar tracking device, particularly to a low-price giant-area-of-view excessive-precision tracking and alignment device in photo voltaic power utilization. 开发利用太阳能，对于节约常规能源、保护环境、促进经济发展都有极为重要的意义，太阳跟踪装置能有效的提高太阳能的利用率，具有广泛的应用前景。

The event and utilization of photo voltaic vitality is of nice significance for saving typical power, protecting the setting, and selling financial growth. The sun tracking device can effectively improve the utilization fee of photo voltaic vitality and has broad application prospects. 太阳跟踪装置现阶段普遍采用的太阳方位传感器有四象限光电探测器、PSD和光敏电阻，四象限光电探测器和PSD成本很高，且视场小，光敏电阻虽然成本低视场大，但是跟踪复杂精度低。 为了满足低成本、大视场和高精度的要求，本发明设计研制了基于三块光电池Y型布局的太阳方位传感器及以其为核心的太阳跟踪装置。

The sun orientation sensors generally used in sun monitoring units at this stage embody four-quadrant photodetectors, PSDs and photoresistors. Four-quadrant photodetectors and affordable item tracker PSDs are expensive and iTagPro USA have a small subject of view. Complex precision is low. So as to satisfy the necessities of low cost, giant field of view and excessive precision, the current invention designs and develops a sun orientation sensor based on a Y-shaped structure of three photocells and a sun tracking device based on it. 本发明所要解决的技术问题是提出供一种低成本、无需日历即能够大视场高精度地跟踪太阳的太阳跟踪装置。 The technical problem to be solved by the current invention is to supply a low-cost sun-tracking device able to tracking the sun with a large area of view and excessive precision without a calendar.
