Solar photovoltaic system consists of solar cell, solar controller and battery. Solar panel is the core part of solar photovoltaic system, the role of solar panel is to convert the sun's light energy into electric energy, output direct current into storage battery.
Photovoltaics is an electronic process that occurs naturally in semiconductor materials. When sunlight hits semiconductor materials, electrons are released and can travel through circuits, producing electricity that powers our electrical devices. In certain types of solar systems, which we call grid solar systems, we send electrical energy into the grid, support it, so that the grid can provide more loads with higher capacity and more reliability.
Photovoltaic systems can power any electrical device, from small electronic devices, such as road signs and electronic calculators, to homes and commercial buildings.
Currently, the cost of solar photovoltaic systems has dropped significantly due to improvements in technology, adoption of new materials and advanced manufacturing techniques. Also, installation costs have declined due to an increase in the number of trained solar installers, as well as an increase in experienced solar installers. Most suppliers and manufacturers working in the field of solar photovoltaics offer practical training courses for recently graduated engineers, students and technicians. Mostly, they offer free training courses.
The United States is one of the largest markets for solar PV installation systems in the world and the third largest in the world. Modern solar cells are fabricated from crystalline silicon or thin-film semiconductor materials. The wide application of the two has different advantages. Silicon cells, while more efficient at converting solar energy into electricity, are more expensive to manufacture, while thin-film materials are less efficient but less expensive and simpler to manufacture. Thin-film panels are made by depositing a thin layer of conductive material on a backplane made of glass or plastic. If you've ever seen flexible solar panels on an RV or boat, thin-film technology is what makes these possible.
In modern solar systems, there is a special class of solar cells called multi-junction solar cells, which are used in military applications and satellites. Therefore, today there are a wide variety of applications and a variety of matching modern solar cell types. In fact, there are many models of solar panels for thousands of solar companies, and depending on our application, we can compare them based on output, efficiency, and warranty.
