MONO SOLAR PANEL 280W

36V Solar Panel 280W

Monocrystalline Anti-reflective Glass Boost Bearing Capability

 

When natural gas, coal, petroleum and other non-renewable energy sources were frequently in crisis and energy problems became increasingly the bottleneck that restricted the international socio-economic development, more and more countries began to implement "sunshine plans" to develop solar energy resources and seek new impetus for economic development. Some high-level European nuclear research institutions have also begun to shift to renewable energy. Driven by the huge potential of the international PV market, solar cell manufacturing industries in various countries are competing to invest heavily in expanding production to compete for a place.

 

Features of solar panel
Polycrystalline or Monocrystalline silicon is a material consisting of thin wafers that are cut from a silicon crystal which has grown in several directions. This advanced texturing process provides polycrystalline or moncrystalline solar panels with a higher power output than amorphous panels of the same dimensions, and makes them more cost and space-effective. These individual wafers are assembled into panels that are covered by durable, weatherproof tempered glass. Thanks to their efficiency and durability, these solar panels require virtually no maintenance once installed.

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. Longsun 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.
