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:how does solar panels save energy?
I'm definitely no expert in the field but hope to learn much more in the future. I'm in the infancy stage of researching as many options as possible in the design and construction of a total green house. That being said, a particular local news story sparked my interest when they investigated the cost effectiveness of residential solar panel systems. Here in Austin, Texas, through subsidies and incentives offered, you can install a system that costs roughly 22.5k for about 7. Apparently these deductions come from a federal incentive (which is a very small portion) combined with those set by the city itself. Austin is a pretty progressive city so I imagine their incentives might be a little better than most but you can call your city's general info line (3) and do a little more digging. Another option you might have is renting the equipment. I was told yesterday that a company here in town would allow for the installation and use for a monthly rate. I know how tight cash can be in school and 7 thousand might not be tangible. The whole issue of energy conservation is so prevalent these days that new info is constantly coming out. Give your current energy provider a call and see what they can tell ya. I hope you find something that works for you. -G
Q:Questions about solar panels?
In the US, the average electricity consumption for a house is 958 kwh per month which is 32 kwh per day for a 30 day month. Once you get to New York City, the number of hours of usable sunlight drops to four hours per day so using six hours a day as a guideline and the fact that inverters tend to be 65% efficient, you wind up requiring 8.205 kw of solar panels which at $5 a watt amounts to $4,205 not including the inverter. Your first task would be to reduce your energy use. Keep in mind that the effective cost of solar power in 2007 was 38 cents per kwh. Without government incentives, you wind up paying more for your electricity than had you just bought it from the grid.
Q:How much maintenance do solar panels require?
New solar panels are clean and shiny and they look cool. Then they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Solar panels must be regularly cleaned and maintained in order to keep them operating efficiently and maximize the amount of sunlight they convert into electricity. Unlike windows your solar system needs to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. Solar panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness. See much more about solar panels maintenance below link

Q:A Question about Solar panels?
You are missing one bit of information in order to get an answer. Watts = Volts x Amps Find out how many amps the collector can put out and you can then plug in the numbers into the equation and get your answers.
Q:What is a solar panel?
Solar panel is a battery of solar cells. Solar cell is a device which uses the sun's rays to produce electricity by the photovoltaic effect. The photovoltaic effect involves the creation of a voltage (or a corresponding electric current) in a material upon exposure to electromagnetic radiation. It utilizes the generation of a voltage when radiant energy falls on the boundary between dissimilar substances (as two different semiconductors).
Q:Generator for solar panels....?
Usually, a generator is more cost effective than a battery backup system for your solar panels. Most grid-tied solar arrays are connected to the grid without batteries. My company has installed well over 00 solar arrays for residential and commercial clients and almost none of them had battery systems with them. Many clients asked to see the costs and after that, they agreed that a generator seems better, especially if there is access to fuel readily available. Also, unless there is a battery system, the solar inverters will not operate when the electricity goes out. This is a safety feature, but it keeps you from using any power at all from the panels when the grid goes down. This explains the utility interactive solar inverters compared to the stand alone generators.
Q:How to build a small SOLAR PANEL that will light a 60 watt light bulb?
Making your own photovoltaic (solar electric) panel is a nontrivial matter if you want to get 60 watts out of it. If this is a science fair project, there are some possible paths that I'd suggest: ) Make your own cupric oxide panel. With just one square foot, you can harvest perhaps 0.5 mW in bright sun - enough to power a solar calculator; -or- 2) Buy a panel to light your 60 watt bulb. You could probably get away with a panel that is 6 square feet, but would use a car headlight as the lamp. If you wanted to light a regular household bulb, you would need electronics to step up the voltage, and you would lose a sizeable fraction of the energy just in the conversion. -or- 3) Buy broken solar cell pieces, or individual solar cells, and solder them together into your own panel. This is a LOT of trouble, and is a finicky process to get working and keep working. And it may not end up being cheaper than buying a ready-made panel. But you can claim that you made it! By the way, crystalline silicon panels are in the ballpark of 5% efficient, and a 3' x 3' one would produce in the neighborhood of 20 watts.
Q:time till a solar panel pays itself off?
I have a small system and do not make enough to sell back (no batteries) so it was less than 7 years BUT when you are talking about putting the initial in to a high yield div account and comparing it then I would say it took only 4 years to pay for because I was invested like many others with the capital it would have taken to get a large system and that investment LOST money while my solar pays for itself every year bit by bit. With systems now more efficient and rebates bigger and the investment alternatives not any better it is an easy choice.
