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.
The solar module is the core part of the solar power generation system, and also the most valuable part of the solar power generation system. It can convert the radiant energy of the sun into electric energy, or send it to the storage battery for storage, or drive the load to work.
The degradation of solar panels is not caused by a single phenomenon, but by several degradation factors affecting photovoltaic modules, but mainly due to the aging of the use time. Other causes of solar panel degradation include aging, light induced degradation (LID), potential induced degradation (PID) and backplane failure.
Aging caused by service time
Compared with traditional solar panels, there is a kind of solar panel that can provide up to 50% solar energy. This is the double-sided solar panel we are going to introduce in this issue. Some insiders predict that the double-sided solar panel market will grow ten times in the next four years, mainly because the production cost is becoming more and more competitive compared with the industry standard single-sided solar panels.
