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:Where can I help my company to buy the 3 Busbar Solar Cell for our project?
We are a solar cell company based in China, and we are actually promoting our product on alibaba, where you can find the TP-125M 6.5''x6.5'' 3-busbar solar cell be your choice.
Q:What should I know about the Crystalline silicon photovoltaic cells?
In electronics, crystalline silicon is typically the monocrystalline form of silicon, and is used for producing microchips. This silicon contains much lower impurity levels than those required for solar cells. Production of semiconductor grade silicon involves a chemical purification to produce hyperpure polysilicon followed by a recrystallization process to grow monocrystalline silicon.
Q:Where can I buy solar cells on sale but still good quality ?
There are many ways you can buy solar cells, online, like Amazon.com. Alibaba.com, or local agent who sells more than 10 brands of solar cells produced in different countries.
Q:What is the solar cells market in China?
Solar cells, is the "ideal" energy of human being's life, solar energy has changed the traditional way of obtaining energy by battery technology. But this technology is limited due to what solar cells needs to work- the weather factors, the solar energy battery can not work properly under rainy or cloudy weather. Therefore, solar cells market is not very well developed in some part of China where there are not much sun.
Q:How to explain to students how the solar cells are made?
The Manufacturing Process of solar cells is a bit difficult to explain, but I can send you the details through email if you want.
Q:Which brand of the solar cells is sold with the lower price on the market? Which brand is more practical for the countryside?
Well, it depends on how many and how big is your project. The more you want, the cheaper it is.
Q:How does solar cell technology apply to our daily life?
Through high technology we are using now, solar cell energy is used in our daily life, such as the hot water you are use everyday in taking a shower.
Q:How do people price solar cells? Is it based on a specific way of calculating the cost of solar cells?
According to our calculation the solar power cost around US$230 per square meter is it can generate 120W power supply per square meter.
Q:How to define the poly solar cells as the A Grade one?
You can check with the manufacturers first and they will tell you if the poly solar cells they are selling is the A grade level.
Q:Why are the poly Solar cell specifications is different from each other, they seem to have the different size of 125mm, 156mm, 152mm, is the 152mm's battery technology is higher than the other?
To make is simple first, the numbers you saw such as 125mm, 156mm, 152mm, refers to the diameter of the silicon wafer.
