About PV Solar Arrays
The smallest unit used for photovoltaic conversion is the solar cell monomer. It has a size of 4~100cm2, an operating voltage of 0.45~0.50V and an operating current of 20~25mA/cm2, and thus cannot be used as a power source alone.
In photovoltaic power generation systems, solar cell monomers need to be connected in series, parallel and encapsulated to form solar modules. It can range from a few watts to several hundred watts and can be used alone as a power source. Solar arrays, on the other hand, are solar cell modules that are connected in series and parallel and then mounted on a rack, which can output several hundred watts, several kilowatts, or even more power, and is the power generator of the photovoltaic power generation system.
The frame of the solar cell square array should be as strong as possible, with sufficient rigidity. It should also be light in weight. Installation of solar cell square array should use a certain strength and is conducive to the fixation and support of the metal bracket, in the desert, coastal, polar, high mountain, windy and some other geographic environment is relatively harsh or complex climatic conditions of the region, the solar cell square array of the bracket should be used to some additional measures to enable it to withstand the additional weight of the gusts of wind and snow and ice buildup, to avoid the collapse because of the natural, man-made and some of the big animal damage and collapsing.
Generally speaking, there are three types of mounting forms for solar arrays: mounting on the ground, mounting on columns, and mounting on the roof. The specific form of mounting is influenced by a number of specific factors, such as the amount of space available, the size of the array, lighting conditions, wind loads, visual effects and difficulty of installation, vandalism and theft.
Of the several installation forms mentioned above, the preferred one is installation on the ground because of its simplicity and ease of use. The difficulty of mounting on top of a post is influenced by the height of the panels from the ground. The difficulty of installing on the roof, on the other hand, is determined by whether the roof is steep or not. Working on a relatively steep roof is not only time-consuming and laborious, but also very dangerous.
During installation, it is especially important to avoid damage to the electrical properties of the panels, and for this reason the surface of the solar panels should be covered to reduce the probability of damage. It is also possible to build a fence around the photovoltaic power plant so that animals can not approach the equipment. To ensure system safety. At the same time, the installation of solar panels should be installed facing the sun at noon, and not to the direction of the compass, which is explained in the relevant information. In addition the angle of inclination between the solar panel and the horizontal plane should be greater than 10°. This allows rainwater that falls on the solar panel to slide down to the ground quickly, thus keeping the surface of the panel clean.
There are many types of solar cell modules, which can be divided into: monocrystalline silicon modules, polycrystalline silicon modules, gallium arsenide modules, amorphous silicon thin-film battery modules, etc., of which crystalline silicon (including monocrystalline silicon and polycrystalline silicon) solar cell modules account for about 80% to 90% of the market. Crystalline silicon encapsulation materials and processes are also different, mainly divided into epoxy resin adhesive sealing, laminated encapsulation silicone encapsulation, etc.. At present, the most used is the vacuum lamination encapsulation method, this encapsulation method is suitable for industrialized encapsulation of large-area cells.

While there are many factors to consider when designing an overall system, terminal blocks are an optimal solution for complex electrical system connections. With a variety of color options and configurations, Premier Cable’ terminal blocks offer a range of options to meet your design challenges.
CAN-bus has been widely used in various automation control systems. For example, CAN-bus has incomparable advantages in various fields such as automotive electronics, automatic control, smart buildings, power systems, and security monitoring.
M12 encoding types are A encoding, B encoding, D encoding and X encoding. A-code, B-code and X-code are some of the earliest developed and longest-available M12 connectors. The latest M12 coding types currently under development are K coding for AC and L coding for PROFINET DC.
The three different sizes of NMEA 2000 certified DeviceNet standard cabling are "micro," "mid," and "mini."
The Premier Cable Starter Kits provide everything you need to get to create a basic NMEA 2000 network from scratch.
DeviceNet_network is a fieldbus network protocol based on Controller Area Network (CAN). In the DeviceNet network, the terminal resistor plays the role of compensation and protection for signal transmission. The function of the terminal resistor is to eliminate signal reflection and interference and ensure the signal transmission quality.
