Description
Technical Field
The present invention relates to the technical field of green energy, and more particularly, to a self-powered system architecture including a light-transmitting solar panel.
Background
Solar energy is a modern common green energy source, and in agriculture and fishery, solar panels can be arranged on roofs and wall surfaces, and the solar panels are used for converting sunlight energy into electric energy so as to achieve the effect of self power supply.
The application of solar panels in the construction of greenhouses or fish farms still has many problems to be solved, one of which is that most of the existing solar panels are silicon solar panels, and the silicon solar panels have the characteristic of light impermeability, so that the space light source shielded by the solar panels is insufficient. For example, solar greenhouses used in agriculture today can only grow shading-resistant plants, such as mushrooms, because the solar greenhouse cannot receive sunlight for photosynthesis due to the light being shielded by the solar panels. If a large number of plant lamps are added in the greenhouse, the problems of increased construction cost and power consumption of the solar greenhouse are caused, and most of the plant lamps are full spectrum plant lamps to simulate the irradiation of sunlight, but the full spectrum plant lamps cannot provide the optimal light wavelength required for the growth of different plants, for example, chlorophyll of the plants can reflect green light, so that the provision of the green light included in the full spectrum does not help to promote the photosynthesis of the plants.
Disclosure of Invention
The invention aims to solve the problem that the application of the solar panel is limited because the silicon solar panel has the characteristic of light impermeability.
Based on the purpose of the invention, the invention provides a self-powered green energy system, which comprises a light-transmitting solar module, a solar controller, a battery module, a monitoring feedback module, an environment sensing module and a light supplementing module, wherein the solar controller is electrically connected with the light-transmitting solar module, the battery module and the monitoring feedback module, and the monitoring feedback module is electrically connected with the solar controller, the battery module, the environment sensing module and the light supplementing module; the light-transmitting solar module comprises a light-transmitting solar panel, and the light-transmitting solar panel is used for converting solar energy into electric energy; the solar controller is used for controlling the light-transmitting solar module to charge the battery module, tracking the maximum power generation efficiency of the light-transmitting solar module, generating power generation efficiency information, and transmitting the power generation efficiency information to the monitoring feedback module; the battery module receives the electric energy generated by the light-transmitting solar module through the solar controller to charge and transmits the electric energy to the monitoring feedback module; the monitoring feedback module is used for displaying and setting working parameters of the monitoring feedback module, displaying and setting working parameters of the environment sensing module and the light supplementing module which are electrically connected with the monitoring feedback module, displaying environment information transmitted by the environment sensing module, displaying power generation efficiency information transmitted by the solar controller, controlling the light supplementing module to provide light supplementing rays, and distributing electric energy from the battery module to the environment sensing module and the light supplementing module; the environment sensing module is used for sensing the environment state to generate environment information and transmitting the environment information to the monitoring feedback module.

In an embodiment of the invention, the thickness of the light-transmitting perovskite solar cell panel is less than or equal to 400nm, and the thickness of the light-transmitting perovskite solar cell panel is greater than 0nm.
In one embodiment of the present invention, when the wavelength of the incident light ranges from 550 to 850nm, the light transmittance of the light-transmitting solar cell panel ranges from 6 to 59%.
In an embodiment of the present invention, the monitoring feedback module communicates with the electronic communication device via a network, and the electronic communication device is used for extracting information from the monitoring feedback module or transmitting instructions to the monitoring feedback module.
In an embodiment of the present invention, the light-compensating light includes red light, blue light or a combination thereof.
In one embodiment of the invention, red light is used to adjust the ratio of light time to dark time of the plant, while blue light is used to promote photosynthesis of the plant.
In one embodiment of the present invention, the wavelength range of the red light is 610-720 nm, and the wavelength range of the blue light is 400-520 nm.
