As we all know, photovoltaic power generation system uses solar energy to generate electricity. In order to better absorb solar energy, the main parts of photovoltaic power generation system are installed in the open air, with a large distribution area. In addition, photovoltaic modules and supports are conductors, which makes the photovoltaic system very attractive to lightning, and has the potential of direct and indirect lightning strikes.

Solar street lamps are lighting products that use solar panels to absorb light energy and then convert it into electricity. Many people are quite clear about solar street lamp products, but when it comes to the standard voltage of solar street lamp, many people are not clear. Here is an answer for you.

1. Green energy conservation

The biggest advantage of solar street lamps is energy saving, which is why the public is more willing to accept this new product. This kind of product that can convert sunlight in nature into its own energy can indeed reduce a lot of electric energy consumption.

In a solar street lamp system, whether the size of the solar panel is correct directly determines the quality of the street lamp.

Some common street lamp failures, such as insufficient lighting time, abnormal charging, and even damage to the solar street lamp system, are related to the selection of solar panels. The following is an analysis of how to select solar panels:

Maximum power of solar panel Pmax=open-circuit voltage × Short-circuit current, which is their ideal power, and usually we measure the rated power of solar panels Pm. In practice, the rated power is less than the maximum power, mainly because the output efficiency u of the solar panel is only about 70%.

In outdoor strong and weak current projects, there are usually difficulties in power acquisition or high construction costs. Solar power supply is a common solution, widely used in outdoor wireless network coverage, outdoor wireless monitoring and other projects. This article will introduce the basic knowledge and implementation precautions related to solar power supply.

Heterojunction and traditional crystalline silicon panel

The heterojunction technology is based on the traditional c-Si panel, which improves the composite process and other major defects.
