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.
Heterojunction (HJT) technology has been ignored for many years, but it has been developing in the past few years, showing its real potential. HJT addresses some common limitations of standard photovoltaic (PV) modules, such as reducing the recombination process and improving performance in hot climates.
What is the name of the solar panel array?
A photovoltaic array is a group of solar panels. A photovoltaic array is a group of solar panels that are connected to form a larger photovoltaic device (PV system), called an array. The larger the overall surface area of the array, the more solar energy it generates.
What are the five main parts of a solar array?
Each solar panel has several main components and some optional components. Solar inverters, AC/DC disconnectors, solar panels and solar supports are important components of any installation.
If necessary, add solar power meter, battery, charger controller and solar cell storage unit.
The solar cell array is composed of interconnected solar modules composed of multiple solar panels. Solar arrays, also known as photovoltaic arrays, meet the energy needs of large residential and commercial buildings.
Brief introduction of the solar street lamp
Solar street lamps are powered by crystalline silicon solar cells, stored by batteries (gel batteries, sealed lead acid batteries, gel batteries, lithium iron phosphate batteries), and super bright LED lamps as light sources, controlled by intelligent charge discharge controllers, used to replace traditional public power lighting street lamps.
