120W TUV Ce Mcs Cec Polycrystalline Solar Panel with Good Quality (JINSHANG SOLAR)

FAQ                       

Is solar power difficult to use?
Although the production of solar panels incorporates a high-tech manufacturing process, it is really very easy to use a photovoltaic system. Solar panels have no moving parts to wear out, they can be used alone or in combination with other energy sources, and they are silent, reliable and long lasting.

What can you power with Photovoltaics?
A properly designed photovoltaic system can supply electricity for many applications, from small remote lighting needs to megawatts of power for large utility companies. An advantage of photovoltaic power is that it can do anything a traditional power generator can do, only without consuming pollution-causing fuel, or requiring noisy motors.

What is a PV system?
A PV system consists of all the equipment and materials needed to generate solar energy, including solar panels (often called modules), a support structure, wiring, an inverter, a meter and other equipment as required by a specific application.  JUST-SOLAR's PV system for commercial buildings, and ET Solar system for residential uses are examples of complete PV systems.

What is a solar module?
Solar modules are series of solar cells, wired together and enclosed protect them from the environment. They are often referred to as in self-contained glass units to solar panels as well.

How do solar cells work?
Solar cells are solid-state devices in which photons (or packets of light) collide with atoms. This process transforms the resulting into electrons. These electrons flow into wires connected to the cell, thus providing electric current to appliances, lighting systems or other electrical loads; and all of the power comes directly from the sun.

What is Photovoltaic Power?
Photovoltaic (PV) power is a term used to describe the process of converting sunlight into electricity with solar cells. These cells are specially constructed from semiconductor materials, and are treated to generate a flow of electricity when sunlight shines on them.

Why choose our solar panel is you ideal choose?

1. The important raw material, Solar cells, come from domestic public company .Quality assurance: 25 years long life span, Industry leading power output warranty 10 years 100%, 20 years 95%, 25 years 85%. 

There are some company which select inferior solar cells that are processed from recycled silicon material from small workshop, so their solar panel service life maybe less than 5 years because inferior solar cell power reduce much more every year.

2. Our company has automated production line for solar panel. Good technology, good quality assurance. Strong production ability: 300 pieces 300w solar panels can be manufactured per day. Most of 
company weld solar cell with artificial manual work. Bad manufacturing technique is difficult to keep consistency of products
