In the current development of new energy, with the rapid development of solar photovoltaic power generation technology, solar wall lights, which have been vigorously promoted, have been widely used. Solar wall light has been developed in an all-round way because of its advantages of running cost, low service life, safety, stability, green energy saving and so on. In order to better realize the lighting of solar wall light, how can solar wall light manufacturers better improve the charging efficiency of panel?
The solar panel of solar wall light will become dirty due to long-term use, and will be covered with dust, fallen leaves and so on, which will block the solar panel and affect its absorption of light energy. Therefore, the solar panel should be inspected and cleaned regularly. When cleaning, it should be wiped with a soft wet cloth during the day or night when the light is not strong, so as to ensure the cleanness of the solar panel and enable it to effectively absorb the light energy of the sun.
The charging efficiency of solar wall light mainly includes two aspects, namely, the conversion efficiency of solar panel and the secondary conversion efficiency. The conversion efficiency of solar panel refers to the efficiency of converting light energy into electric energy; The secondary conversion efficiency refers to the efficiency that the light energy is stored in the storage battery after being converted into electric energy.
In order to improve the secondary charging efficiency of solar wall light, the capacity of storage battery is generally 1.2 times of the system power in the configuration process of solar wall light to meet the night lighting demand. Moreover, in order to guarantee the service life of the solar wall light controller, the whole control circuit should be protected during the overcharge process.
As far as the development of solar wall light technology is concerned, only by improving the secondary conversion rate of solar wall light during daytime charging can it be realized in the rapid development of future application.
