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:How can I understand the working principles of solar cells?
My way of understand the working principles of solar cells is to read tons of books about that topic.
Q:Briefly explain why solar cells are made into components
The electrical performance parameters of solar cells are: voltage, current, capacity, type, charging rate and so on. The voltage parameter of the battery refers to the operating voltage of the battery, that is, the voltage that can be supplied to the device. Current, refers to the maximum discharge current of the battery. Capacity, refers to the total discharge power of the battery, with An / hour (A / H) said.
Q:How does the solar cell work in terms of photochemical conversion?
The principle of photovoltaic power generation is: the typical material used is silicon (Si), the outer number of electrons is 4, then the silicon consists of four atoms molecular state, known as true semiconductors.
Q:What are the short-circuit currents of solar cells affected by the factors?
The size of the suede, the uniformity, the depth of diffusion, the film thickness of the PECVD, the printing condition of the screen and the sintering conditions,
Q:Is the polymer solar cell the cheapest type among all the different kinds of solar cells?
It's not the cheapest solar cell, but it is cheaper than most otheres.
Q:What are the 3 things you need to know before you start to make solar cells?
Sorry that I can not provide any help because I know nothing about solar cells.
Q:What is the accurate explanation for the sun solar cell power system? How does it work?
The sun solar cell power system is actually working better than the other ways, because the quality guarantee period of crystalline silicon solar cells is 15 years, and the service life is more than 25 years.
Q:Can I buy solar cells easily online?
Maybe, but it takes time to deliver it to you.
Q:How long is the long cycle solar cell life?
A look at the application of the environment, if the ambient temperature is high, then in general, to 25 degrees as a benchmark, each increased by 10 degrees, life-span reduced by half;
Q:The difference between a fuel cell and a solar cell
In general, the fuel cell has the following characteristics: (1) high energy conversion efficiency He will directly convert the chemical energy of fuel into electricity, the middle without the combustion process, and thus not limited by the Carnot cycle.
