Photovoltaic control system and photovoltaic apparatus

Abstract

The invention provides a photovoltaic control system and a photovoltaic apparatus. The photovoltaic apparatus comprises a pedestal, a protection box arranged on the pedestal, a first rotating shaft arranged in the protection box, and a solar cell module arranged on the protection box. The solar cell module comprises a solar cell which is relatively fixed to the first rotating shaft. The solar cell module possesses an expansion state located outside the protection box and a folding state accommodated in the protection box. The protection box is provided with an opening used by the solar cell module to be converted between the expansion state and the folding state. The first rotating shaft is used for driving the solar cell module to be converted between the expansion state and the folding state. By using the photovoltaic apparatus provided in the invention, a condition that the solar cell module is damaged because of severe weather can be avoided, and a storage area of the whole photovoltaic apparatus is reduced. The photovoltaic control system comprises a control system. Through the control system, rotation of the first rotating shaft can be automatically controlled so that intelligent control to the photovoltaic apparatus is realized.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic control system and a photovoltaic device. Background technique [0002] With the continuous development of solar cell technology, the cost of solar cells has been continuously reduced and the efficiency has been continuously improved. Solar cells have gradually moved closer to civilian use. Ordinary households can also install solar panels. The electricity generated is not only for the use of household appliances. , the remaining electricity can also be sent to the grid to achieve additional income. The existing home photovoltaic system structure usually installs solar panels on the open space or on the roof, and then connects them to the indoor control system, such as the Million Roofs Project in the United States. Some also fix solar panels by mounting brackets outside the balcony of the building to realize power generation. [0003] Insta...

AI Technical Summary

Problems solved by technology

[0003] Installing solar panels on open space and roofs requires a lot of land resources. In cities, taking ordinary residential areas as an example, it is difficult to have enough open space or roof area to satisfy every household with solar panels.

The currently used solar panels are usually packaged in glass, which is relatively heavy. In order to fix the heavy solar panels, a lot of hardware brackets are needed to fix them, and the angle cannot be adjusted, and the incident angle of the sun will change with time. , which will inevitably lead to the inability to maximize the use of the day's sunshine

In addition, in bad weather, the protruding solar panels are likely to cause safety hazards, such as heavy snow, if the snow on the solar panels is not cleared in time, it will increase its own weight, which may lead to potential breakage of the bracket. For high-rise residents, it is not very convenient to clean the solar panels outside the balcony. Large pieces of snow need to be recycled into the house to prevent injuries caused by falling from high altitudes. For example, in windy weather, the solar panels on the outside are more affected by the wind. Big, it may even be blown off by the wind in severe cases
