Description

A high capacity solar beam energy accumulating apparatus

The present invention relates to a large-capacity solar energy integrated device, and more particularly, by mounting a plurality of solar panels on a frame and simultaneously operating these frames and solar panels in accordance with the direction of solar movement. The present invention relates to a large-capacity photovoltaic energy integration device capable of obtaining an optical energy integration effect.

In other words, it is an invention belonging to the technical field related to the solar energy integrated device which converts sunlight as a main alternative energy into electrical energy.

As the depletion of petroleum energy and environmental pollution have become a serious problem for the entire human race, countries around the world are concentrating on developing alternative energy.

As such, in order to accumulate the maximum amount of solar energy, a solar tracking sensor unit is used to increase the solar energy integration efficiency by directing the solar panel to face the sun all day long, or The company has chosen to increase the amount of solar energy itself by arranging and installing a large number of solar panels in a specific large place.

However, these two types of methods, namely, the method of increasing energy integration efficiency by using a solar tracking sensor unit (method 1) and the method of increasing energy accumulation by installing a plurality of solar panels (method 2) are both large-capacity solar energy. There was an impractical aspect of the energy accumulation method.

For example, if a large number of solar panels are installed for large-capacity solar energy integration, there is a problem (method 1) in which the cost of installing and managing the sensor unit and associated programmable logic controller (PLC) is high. It is inevitable to point out that solar energy efficiency is low (method 2) except for a certain time zone (about noon).
