Problems solved by technology

[0004] However, in the prior art, the charging method for the solar battery to the rechargeable battery waiting for the charging equipment is all realized by a converter, that is to say, the solar battery cannot directly use the solar energy after collecting it, but needs to be converted to recharge the battery. Waiting for the charging equipment to charge, so there is a problem of charging conversion efficiency and cost, which is not conducive to the conversion and utilization of solar energy

Abstract

The invention discloses a power unit for solar charging, and relates to the field of solar cell charging. The power unit comprises a solar cell for converting light energy into electric energy; and anenergy storage battery used for storing the electric energy output by the solar cell. The solar cell is directly connected with the energy storage battery. The limitation of a solar cell conversion module on charging is eliminated, the solar cell directly charges the energy storage cell, the electric quantity loss is reduced, and the heating value is reduced, so that the cost is effectively reduced, the charging efficiency of the power unit is improved, and the conversion utilization rate of solar energy is further improved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a power unit for solar charging. Background technique [0002] As a new type of green renewable energy, solar energy is the most ideal renewable resource compared with other new energy sources. In recent decades, with the continuous advancement of science and technology, solar energy and related industries have become one of the fastest growing industries in the world. The application of solar energy in our country started late, but the development speed is very fast. my country's photovoltaic industry has played an important role in meeting the needs of the domestic market and improving the living standards of people in remote areas without electricity and in special industrial applications. However, the power generation status of solar photovoltaic panels is greatly affected by weather, temperature, and natural environment, especially at nigh...
