Solar LED lighting system technologies and engineering design
The Solar LED lighting is a practical knowledge website that organically combines the design of LED solar lighting system with lighting technologies engineering application
The previous article introduced the determination of series and parallel number of solar cell module. But in practical situations, it is necessary to revise the theoretical results considering the actual situation to obtain more correct results. (1) Reduce the output of solar cell modules by 10%. In actual operation, the output of solar cell modules…
The number of solar cell modules in series Ns The required working voltage can be obtained by connecting the solar cell modules in series according to a certain number, but the series number of the solar cell modules must be appropriate. If the number of series connection is too small, the series voltage is lower…
The daily output power of a solar cell module is related to the number of cells in series in the solar cell module. The voltage of the solar cell under sunlight will decrease with the increase of temperature, which will lead to the increase of the voltage of the solar cell module with the temperature. and…
Calculation of solar cell capacity The basic data required for solar cell capacity calculation are: (1) Determine all the load power and continuous working time, the rated working voltage of the load and whether there are special requirements. (2) Determine the geographic location of the solar cell module installation: longitude, latitude and altitude. (3) Meteorological…
The power of a solar cell module is proportional to the area of the solar cell, but the area of the solar cell is not exactly equal to the area of the solar cell package panel. Although some solar cell panels are large, the gaps in which the solar cells are arranged are very wide,…
