Poly Solar Panel 70W A Grade with 12 Years Warranty 


Production description

Solar power is the conversion of sunlight into electricity, either directly usingphotovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into an electric currentusing the photovoltaic effect.[1]

The International Energy Agency projected in 2014 that under its "high renewables" scenario, by 2050, solar photovoltaics and concentrated solar power would contribute about 16 and 11 percent, respectively, of the worldwide electricity consumption, and solar would be the world's largest source of electricity. Most solar installations would be in China and India.[2]

 photovoltaic system, also solar PV power system, or PV system, is a power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, includingsolar panels to absorb and convert sunlight into electricity, a solar inverter to change the electric current from DC to AC, as well as mounting, cabling and other electrical accessories to set up a working system. It may also use a solar tracking system to improve the system's overall performance and include an integrated battery solution, as prices for storage devices are expected to decline. Strictly speaking, a solar arrayonly encompasses the ensemble of solar panels, the visible part of the PV system, and does not include all the other hardware, often summarized as balance of system (BOS). Moreover, PV systems convert light directly into electricity and shouldn't be confused with other technologies, such as concentrated solar power or solar thermal, used for heating and cooling.

Q:The advantages and effects of solar energy
Solar batteries are widely used, such as artificial satellites, unmanned weather stations, communication stations, TV relay stations, solar clocks, electric pole, black light, beacon lights, railway lights. Solar thermal conversion technology products, such as water heaters
Q:Where can I get a competitive price for this solar cell? The 2bb/3bb polycrystalline solar cell panel?
Here is some detailed information of our 2bb/3bb polycrystalline solar cell panel: High conversion efficiencies resulting in superior power output performance.
Q:What is the best way to deal with surplus solar cells abandoned after burning?
It could be a very good resource to be used, but the technology needs to be more advanced to really deal with that.
Q:Where can I buy solar cells?
Usually you need to go to a special store selling power generation products.
Q:My solar cells are broken, can I just buy one and replace it?
You need to hire a professional to fix that for you.
Q:Do you believe you can make a solar cell by using kitchenware?
As a scientist, I think it's possible.
Q:What is the accurate explanation for the sun solar cell power system? How does it work?
Even though the sun solar cell power system is much more developed then before, its working process is still a bit complicated compared to the conventional power supply system.
Q:Why is the solar cell produced by DC
The electrons in the outer layer of the semiconductor nuclei are absorbed into the high energy level when they are exposed to light. The unstable electrons are returned to the semiconductor by the external circuit. The direction of the movement of the electrons in the external circuit is determined.
Q:What is the solar cell?
The structure of solar cells is diverse. Now, PN-type solar cells composed of P-type semiconductors and N-type semiconductors are used. They are mainly composed of P-type and N-type semiconductors, electrodes, and antireflection films.
Q:How many years should I spend in the solar cell industry to be a good solar cells sales person?
I worked as the solar cell sales for a foreign company for 3 years, and I am already the best sales in my company.
