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 am interested in installing a home solar panel system. In my city, we get a little over 5 hours of sun, and I typically use about 800-900 kwh per month.The available roof space is small- approximately 600 sqft.The online calculators provided on various sites are not uniform, thus providing inconsistent responses with the same input data.I think I need a 5kw system approximately. Can anyone verify that and provide a link for a reasonably priced system to meet my needs? Prefer grid-tied, but off-grid is acceptable as well.Thanks!
- I think this will help you a lot. :)
- Q: Im doing a project and i have to persuade some one that solar pannels are great... help ?
- Solar panels are eco friendly, they produce with out disturbing the enviroment. Instead of having to build dams and kill of species that have water homes we can use the sun as our energy source. im all for solar panels i hope this helps :)
- Q: I'm looking at solar panels and I have NO IDEA what this stuff means.They come in catagories of Watts. What does that refer to? If a solar pannel is in the 200-watt catagory, what does that really mean? Will it produce 200 watts an hour, a day, a week, a month, a year?? How many watts of energy does the average house use up in one month? I really wish they would just tell me on the website!! :(0 points!!!!!!!! :D
- This is not a precise analogy, but think of it this way: Volts is the pressure of the water in a pipe. Amps is the gallons per minute that come out. Watts is how much water you have after a certain length of time the pipe is open. a 200 watt solar panel under ideal conditions ( bright daylight between , say 0 am and 2 pm, held exactly flat to the sun ) will produce enough energy to run 2 00 watt light bulbs. You hardly ever have perfect bright sunlight; the length of the day varies during the year, and the angle of the panel to the sun changes from hour to hour; all this leads to a typical home in the US /Europe having only about 4 hours a day of maximum solar available. So, your 200 watt panel would give you 800 watts a day, enough to run one 00 watt light bulb for 8 hours If you are trying to run a house off solar, there are unfortunately other things needed between the panels and the lights / appliances; inverters, batteries, controllers sand each one eats up a little energy so you may get only 75 useful watts. See why more homes don't have panels? The other poster who said $30-50,000 to completely run a home on panels is about right.
- Q: Can solar panels be used to power a farm?
- Yes, solar panels can be used to power a farm. By harnessing the power of the sun, solar panels can generate electricity that can be used to run various farm operations such as irrigation systems, grain dryers, electric fencing, and even power agricultural machinery. This renewable energy source not only reduces reliance on fossil fuels but also helps farmers save on energy costs while promoting sustainability.
- Q: I've been reading up on Solar panels because I think in the long run this would be beneficial in the long run. My Dad had looked into it before passing and had said it was too expensive. How much does it range for getting them placed on the roof and how exactly does that work? I think I remember being told that PGE has incentives and could possibly even end up paying you for having it? What does having panels cover? I know electricity but does it also heat things up? Sorry I'm kinda dee dee dee on this lol. Any and all information would be greatly appreciated. If anyone has solar panels can I get your experiences with them? Thanks!!
- There's a few different kinds of solar panels. Some of them are only for collecting heat, they're relatively inexpensive and not a bad deal, though installation can be expensive of course. The most sophisticated of these use some pretty high tech collectors to heat up an antifreeze solution that in turn is circulated through a reservoir (how water heater), to supply the house. Your electric producing solar panels are more expensive. You can go on OKorder and do a search on photovoltaic panels and get a pretty good idea real quick. The panels alone can run you 2 or 3 bucks a watt of output or more, and you may need 3 or 4 thousand watts of output to give you reasonable system for your house, depending on how much electricity you use. Then there's installation, for which you may need a professional electrician and so on. If you want a system incorporating deep cycle batteries then that's another expense, but you don't necessarily need those if you're not planning to take yourself completely off the grid. Not that the systems are really complicated. Some people wire panels together themselves from scrap cell components to save money. Of course you'd need to understand the basic wiring involved for that, and you'd almost certainly be required to retain an electrician to tie any system into the grid itself. Although there is such a thing as a plug in grid tie inverter. This is is a gadget that will take your DC solar panel output and feed it into the standard wiring of your house via an ordinary electrical outlet. You'd still need to understand enough to get the DC voltage right no doubt.
- Q: could any tell me what type off panel is the best tube or flat and how much it should be. I live in N Ireland
- The type solar system to be installed your new house depends the shape and dimensions of house.Himin newly launched solar house.
- Q: Aren't batteries bad for the environment?Toxic?Expensive? With small solar panels phones, iPod's, laptops other small electronics could be smaller, slimmer, more efficient cost people less to charge every day. Maybe a small battery inside as a backup and to store the Solar energy for night time. But overall, batteries should be optional. So big question:Why aren't electronics being produced with solar panels?
- Solar panels could still be expensive, which would also raise the cost of the item.They also are made with chemicals that harm that enviroment(not too badly, but ya know..) You would also need to charge them, of course, in sunlight and most people enjoy the benefit being able to plug something in and still being able to use it. Not saying it's a bad idea, just the world we live in.
- Q: What is a good sight that I could go to about installing solar panels and all of the considerations of it?
- Just okorder
- Q: So I'm trying to figure out what to ask for my birthday because its one of the few times I can get stuff for no reason, like stuff I don't normally go to the store to buy. (i dont go to the store to get much at all anyway).Anyway, I'm interested in solar panels and led and electronics and i was wondering if there is anything not over expensive that would be cool. Some things I'm interested in:solar, wind, water energyGadgets (multitools, swiss army knives)Vibram fivefingersdrawingmaking stuff (duct tape wallets, stuff out of altoids containers)basically technology and outdoors-gear stuffoh and im 6 turnin 7 male.
- solar panel is expensive, but small solar panel is not expensive, for example, 5w solar panel, solar light also not expensive led light also not expensive. i am not sure about other stuff that you said
- Q: i was reading the popular science magazine and i saw that they might make a Sun Powered it Absolutely NOT possible to make a car with a Solar Panel? I dont see any harm in making it..
- There are lots of cars with solar panels, but they are all experimental. The problem is that the power required to run a car is a lot more than the limited number of solar panels can produce. The sail boat can use the solar panels as sails, to get power from both.
