Poly Solar Panels 250W is designed for large electrical power requirements.
It is the optimal choice for both on-grid and off-grid power systems.
Solar panel offers high performance of power per square foot of solar array.
Poly Solar Panels 250W of Monocrystalline silicon(c-Si): often made using the Czochralski process.
Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon.

- Q:I'm curious, for those who have had solar panels installed on the rooves of their houses:How much did you pay? How much energy do the panels produce? Did it dramatically cut down on your electricity bill? Was it worth it? Thanks!
- There are two officially advanced desert storm offices with true solar equipping. The systems are both from Nasa type scientists both private property sales. The use of California for the study is because it requires 30 hours per month to keep the satellite sector in alignment. The owner was very specific to each company that all uses had to have junior sim companies for wider availability. The fact remains solar energy is magic, cost of a large ranch in the original maker was reduced with larger needs like barns, greenhouses, spas, and guest cabins by 78%. An average house would not save. The technology best junior designers is around 5000 and will save 25,000 in some high cost locations per lifetime.
- Q:I know the basics of how solar panels work. Solar panels convert sunlight into DC electricity which is stored in batteries which would need to be run through an inverter to convert it to household AC. But is there a way for the appliances to use the solar panels electricity FIRST and any additional power from the grid? Is that how it works or do they only run specific devices(water heater, pool pump, etc)?
- The utility is your battery. Doesn't make any difference which is used first. At least that's the case in Calif. However, you need an electrician to do the attachment, and probably an inspection by the utility.
- Q:I don't remember what number exactly but it's in the single digits. This number represents how efficient solar panels are at capturing the sun's rays and converting it into electricity.Why?
- I don't remember what number exactly but it's in the single digits. This number represents how efficient solar panels are at capturing the sun's rays and converting it into electricity
- Q:We are looking in to buy solar panels for our house. The payment has to be around or under $4000. Our house is a 4 bedroom and 3 bath 2-story house. (Around 2500 sq. ft.) Where can we get the solar panels? Also: Will it heat our water? When we get the solar panels, what direction do they have to be facing?

- Q:A few months ago my dad said something about getting solar panels, and how green they were. I was just wondering if there were any companies that sold them and if they would actually make a big difference.
- Yes there are companies that sell solar panels, many of them specialize in solar, a simple google search with your state or city name and the word solar should get you many results. There are actually two kinds of solar panels that get installed on homes, one kind creates electricity, the other heats up water. Depending on how large a system you installed, you could have all of your electricity or hot water powered by solar, which would mean you'd use less nonrenewable resources like coal, oil, or natural gas. The other difference the solar panels would make would be in your electric or gas bill, that number would go down right away, but you'd have to wait a few years before the money you save there would cover the cost of buying the panels, the number of years depends on your state, and the size of your system. Starting in January there will be a 30% federal tax credit, that would mean savings for every installation in the US. Also a lot of states now have a rebate program, which means the system is even less expensive.
- Q:If I put a 5000 watt solar panel kit on my roof in Dublin (Ireland) - how much electricity would I realistically expect to get?An educated guess at a percentage of 5000w would do.
- This is dependent on sun angle, clear sky, shadow interference, clouds, etc. First if you purchased the PV panels and they are rated for 5 kW, the factory rating is based on a particular incident energy, 000 watts/square meter, 25 degrees C and an AM of .5, reaching the panels. It is more likely that you will not obtain this same level in the open air. If we assume you will get 80%, then the maximum kW would be closer to 4kW. This will be produced during peak, clear days with the panels placed perpendicular to the sun at all times during peak radiance times. When the sun first comes up and later when it is going down, there will be more than the thickness of .5 atmospheres between you and the sun, so the radiant energy hitting the solar panels drops off. Total energy is watts time hours. I would expect you PV system to produce about 750 kW-Hr of energy during a clear summer day at peak solar height. Hope this helps, NewtonLaw
- Q:I live in Los Angeles area, I see the ads that, they will install solar panel for $0. I would like to know what is the catch ?Thanks You.
- using solar panel in your life, you can save the electricity bill, also you are saving energy for our later generations. If more and more people are using solar energy, the mother earth will become more beautiful.
- Q:I riped two solar panels out of some solar light and tested them. I found out that they both produce 2 volts(I have no idea on the watts or amps). Iquot;ve hooked them up to an electric motor that can be driven by a AA battery, but when I hook the solar panels up to them nothing happens. What is wrong?
- Mark G has a good answer. If you leave your voltmeter on the solar cells when you hook up the motor, you will see the voltage drop to near zero. Same thing would happen if you tried to use 2 9 volt batteries to start your car. They just cant maintain the voltage when high curent demands are made.
- Q:I have a panel that quot;deep breatheproduces at 4% efficiency, what can it power, It's about 4ft by 2ft
- I also doubt your claim of 4% efficiency. That strength solar panel is brand new technology (this year) and is not available in retail sizes yet. You probably got duped by some false marketing... In any case; even assuming you had a 4% solar panel, there are too many things for us to give you an accurate assessment of the power production. Clouds, location on earth, season, angle of the solar panel; these are all things we need to know to calculate it. Odds are it should have the average rate it produces electricity written on the back panel or with the instructions that came with it. I know of no solar panel retailers that do not also offer free installation. You should get your money back or get that free installation (and then you never have to worry about how much power it has, it just gets you what it can).
- Q:I'm trying to charge rechargeable AA batteries with a solar panel. What guage wire should I use to connect the panel to the batteries? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size? My panel is 4.8V 50mA.
- With that size panel, you should be able to recharge either AA battery, or two AA batteries in series. Yes, it would be a good idea to put a blocking diode in series with the panel - anything will do, like a N448. You will want to use NiCd batteries if possible, because they take a trickle charge of 50 mA much better than NiMH (which prefers pulse charging, a more complicated circuit). You can use NiMH if you must. Needless to say, don't try to charge non-rechargable batteries. Also realize that at this charge rate, it will take days, maybe even a week, to charge the batteries, if left out in full sun all day long.
