3.Usage and Applications of Poly Cells

Solar cells are often electrically connected and encapsulated as a module.

Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage.

Connecting cells in parallel will yield a higher current;our solar cells have passed IEC Certification.

With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.

Q:I have heard a lot about solar panels and I want to know how these solar panels works and is it really possible to generate electricity using solar panels. And what is the cost of getting a solar panel installed?: They consist of a semiconductor junction which has an uneven distribution of charge so it has an electric field in it. When light hits the material, an electron is knocked off from its parent atom and can move around the material. The electric field pushes it in one direction, et voila. You have current! (it's most complicated than that, but it needs quantum physics to understand). In summary, light goes in and DC electricity comes out of the panel. To use it in your house you will need an inverter as well, which turns it into useful AC. Then you need a way of using up the extra electricity you produce when it's sunny but you're not using power Some people use batteries, most people use 'grid tied' systems, plug in to the national grid and sell electricity to power companies that you're not using! Unfortunately, without major subsidies (like those offered in Germany, Japan and soon the UK), solar panels aren't likely to be cost effective. In the UK it costs about ?5-6,000 to install a kWp of solar power and it will make about ?90 of electricity a year. In California it's sunnier, so would make about ?200 of electricity a year, but it's still very VERY expensive without subsidy. On the plus side, technology is improving. Thin film technology can be done at half the price, so I'd say hold on until thin film solar cells go up for sale (right now they only sell them to companies for big projects). Prices should drop by at least half in the coming years if they can make enough to sell to households - and at that price it'll be worth it in places like California.

Q:The average solar panel produces 0% of the energy that is put into it. What is happening to the other 90%? Is it being reflected or is it being obsorbed by materials that are not a part of the solar cell? Is it possible to one day have near 00% efficient solar cell technology?: Mainly due to reflection (micro-structuring of the surface helps here), incorrect wavelength of the light (the panel is only sensitive to a certain wavelength range) and heating of the panel (due to the incident light/thermal radiation). The remainder is either reflected or absorbed by the cell and re-emitted as heat. Absorption by e.g. the glass panel is slight (a few %), as is absorption/reflection by the necessary surface contacts (again, a few %). Higher efficiency is possible, but brings its own drawbacks (like higher cost). You could now go into two directions: - high efficiency cells/panels with (likely) higher cost and complexity for mounting (like lens or mirror based systems, aka concentrator systems, that increase the light level on the cells in order to increase efficiency) - low cost systems (cheap as dirt) that will allow you to cover every surface of a building, efficiency is less important if you can compensate by a much larger covered area As to the efficiency limit: there is a theoretical limit (from thermodynamics - don't ask me how or why) in the range of 30...40%, depending on which publication you want to believe in.

Q:Can solar panels be used to power an emergency response center?: Yes, solar panels can be used to power an emergency response center. Solar panels can generate electricity from sunlight, which can then be stored in batteries or directly used to power the center's equipment and infrastructure. This renewable energy source can provide a reliable and sustainable power supply, making an emergency response center less dependent on traditional energy sources during critical situations.

Q:How many solar panels would it take to run an electric motor the needs 480 volts and pulls about 45 to 50 amps?: If you have 480 volts, it might be 3-phase, and not a simple matter of multiplying volts and amps. However, that's in the ballpark of 25 kW, very doable for solar. That's on the high end of a residential installation, but very small for an institutional installation. What will influence the size of the array more is where you are geographically (that is, how much sun you get), and how often the motor runs (that is, how much energy in kWh does it use per day)? 480 volts is nothing to be trifled with. You should really get a power engineer to architect your system.

Q:Can solar panels be used in areas prone to hurricanes?: Yes, solar panels can be used in areas prone to hurricanes. However, it is important to ensure that the panels are properly installed and designed to withstand high wind speeds. Reinforcements, such as additional framing or anchoring systems, can be used to make the panels more resilient to hurricane conditions. Additionally, regular maintenance and inspections are necessary to ensure their stability and functionality.

Q:Can solar panels be installed on forests or protected areas?: Solar panels can be installed in forests or protected areas, but it should be done with careful consideration and planning to minimize the potential negative impacts on the ecosystem.

Q:solar panel capacity, how do it work: Solar panels are made of solar cells.Solar cells are mainly made of a semiconductor called silicon,when sunshine on it,solar energy is converted into electrical energy by photovoltaic.The energy knocks electrons loose, allowing them to flow freely.This flow of electrons is a current, this current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce.

Q:who has solar panels on their home and are they worth it: Well I have some. I think it's a great investment. If you have the money it's totally worth it! If you notice on some street lamps there are solar panels. I am sure the town wouldn't waste there money it must be worth it. Schools are investing in it and lots of business. If I was you I would go for it. I was really happy with the company that did it for m- but they only service New York and New Jersey, not sure were you live. Enjoy saving money!

Q:can this amount of solar charge these batteries.: Wow I think that your battery are too big or in othercase your solar system panels are too small. But making some calcs if you connect your panels in parallel you will have 30 Amps of Recharge for your batteries. Assuming that your batteries are discharged to .75 V/C you will need at least (. x Ah removed)/Recharge Amps = (. x 550Ah)/30A, that means that you will need 20 Hours to recharge your batteries Literally this is imposible to have fully charged your batteries for a proper application you will need 65 Amps from your panels to recharge your batts in 4 hours or de-rate your batteries to 00 Ah

Q:Can solar panels be installed on military bases or installations?: Yes, solar panels can be installed on military bases or installations. In fact, many military bases around the world have already incorporated solar energy as a part of their sustainability initiatives. Installing solar panels on military bases not only helps reduce their reliance on traditional energy sources but also enhances their energy security and resilience.
