We are one of the biggest factories in China who have been TUV certificated and specialized in producing solar mounting system,we can supply many kinds of mounting system for different install conditions, flat roof, pitched roof and ground,etc. Flat roof solar mounting system installed household power generation systems generally consist of a photovoltaic array composed of solar cell components, solar charge and discharge controllers, battery packs, off-grid inverters, DC loads, and AC loads，also we have our own factory of l shape steel angle&l shape steel factories. If the output power is AC 220V or 110V, an inverter is also required. The photovoltaic array converts solar energy into electrical energy when there is light, and then supplies power to the load through the solar charge and discharge controller, and at the same time charges the battery pack; when there is no light, the battery pack supplies power to the DC load through the solar charge and discharge controller. At the same time, the storage battery also needs to directly supply power to the independent inverter, and the independent inverter is inverted into alternating current to supply power to the alternating load.

Ever wonder how solar panels are made? Or how a solar system works? Here's a Introduction of Square tube&galvanized omega .You own the sun. Well, not exactly, but you do have the right to its power. Why not put it good use? With solar technology, you can harness the sun's energy and turn your rooftop into a power plant. 

To make a solar panel, we string together 48, 60, or 72 of our solar cells and lay them carefully within an encapsulant, which attaches high-transparency glass on the front surface and a highly durable, polymer-based backsheet on the backside. Then, we warm the whole stack (like a toasted solar sandwich to create a protective cocoon around the solar cells. 

Most solar panels produced today are made from Silicon, the second most abundant element on Earth and the primary ingredient in beach sand. The first step in making a solar panel is to create silicon ingots, giant blocks of high-purity (99.999999%) silicon. To do this, we put hundreds of pounds of silicon chunks (i.e. rocks) into a giant crucible and add a little boron (called a dopant ) to give the silicon positive polarity. Then, we cook it altogether at over 2,000 degrees Fahrenheit 

We let the large silicon ingot cool down before slicing it into thin wafers using wire saws. Each fresh-cut silicon wafer is less than 200 microns thick similar to a heavy piece of paper. These wafers must be carefully handled, inspected and cleaned before further processing. 

The next step is to reduce the reflectivity of the wafer from about 30% to 10% through a chemical surface texturing process that creates tiny pyramids on the wafer s surface. Now, when a photon (sunlight) hits the wafer's surface, it is more likely to be reflected into the wafer rather than back into space. Now we have a photovoltaic (photo = light, voltaic = energy; thus, light into energy ) device! Next, we deposit metal contacts on the front and rear surfaces of the cell, allowing us to collect those electrons generated in the silicon. We also deposit a thin chemical layer on the cell's surface to reduce its reflectivity from about 10% to 1%. 

Next, for structural stability and long-term protection, we place rigid aluminum frames around the perimeter, bonded together with a waterproof adhesive. Finally, we add a junction box to the back of the solar panel: a connector to facilitate the flow of electricity. Now, the solar panel is ready for quality testing, packaging, and delivery. 

Once your solar panel is installed on your rooftop, sit back, relax, and let the sun save you money.Write a book, make coffee, or watch a soccer match on TV: you choose what to do with your solar electricity. 

Solar energy is everywhere. You may not be able to dig a coal mine or oil well in your back yard, but with the Solar panels you can harness nature s highest source of power. The sun sends enough energy to Earth each hour to meet human energy demands for an entire year! It s the world s most abundant and accessible source of energy. 

In the bracket installation method, the battery assembly is supported by a metal frame and presents a preset inclination angle. For the square array installed with brackets, the brackets are fixed on the roof with screws. This installation method will cause problems such as increased roof load-bearing and wind stress. However, since the air flow path completely surrounds the battery assembly, the assembly can maintain a relatively low operating temperature, thereby improving efficiency. Some bracket installation methods can adjust the inclination angle according to the season to improve the efficiency of the photovoltaic system.

Solar power and flat roof solar mounting can be installed on the roof of the villa.

The energy of solar energy is energy from celestial bodies outside the earth (
