1.Structure of

Polycrystalline Silicon Solar Panel for 250W

I. High efficiency crystalline silicon solar cell. Even if under the weak light, the solar module can produce maximum power output.

II. Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

III. EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

IV. AI frame: Without screw, rner connection. 6 holes on the frame can be installed easily.

V. Junction box: Multi function junction box with water proof.

VI. Long lifetime: ≥25 years; Less power decrease.

VII. Good performance of preventing from atrocious weather such as wind and hails.

VIII. Resisting moisture and etching effectively, not effected by geology.

IX. The certificate issued by international authority: UL, TUV, IEC, CE.

Q:Whats the annual energy output of the average solar panel.?
The energy output is highly dependent on the location. For a specific area, you can look up the equivalent peak sun hours per day here: Let's say that it says the peak sun is 5 hours / day in your location. Then a typical 200-watt panel would have 5 x 200 = 000 wH = .0 kWh per day, or 365 kWh annually. The tables above already take into account average cloudy days, and seasons. A typical size installation would have perhaps 6 of these panels, but it could be less, or much more.
Q:how much money can I make a year for the electricy I sell from a solar panel?
call your power company and ask them how much they pay for each kWh you feed back into the grid (the price may vary for different times of the day). then multiply that by however much electricity you are producing.
Q:What solar panels are the most efficient?
New rollable panels are becoming available that don't have to be permanently attached to a surface and that are more resistant to damage than conventional panels. Right now they are also even less efficient than photo cells at about 0%, but the cost factor may make up the difference. Solar thermal is more efficient than photovoltaic cells. They focus sunlight with mirrors onto a pipe containing a liquid which is then heated to it's boiling point. That turns a turbine to produce power or is harnessed in some other way. The panels are cheap compared to photo cells, don't require perfect manufacture or exotic materials, no expensive maintenance and they are much easier to repair. I don't know of any available to individuals yet but there are at least two companies building generating plants in Nevada with this technology. SunPower is about 22% efficient but even at that rate it will take decades to pay for itself and the panels are unlikely to last that long at anything near optimal efficiency. The cost is just too high at present but solar thermal may provide a good alternative until photovoltaic cells mature, if you can cobble together a system. The final link is about a claimed 80% efficient solar cell that even generates some power at night. It's based on nano-technology, like many promising energy developments in batteries, electrolysis and ethanol production. If it works as advertised it should revolutionize solar tech. Eventually.
Q:solar panels vs (organic) plants?
Of course solar panels
Q:What SOLAR PANEL kit do I need?
You Depending on your needs, you may have to have these customized for your home, but they at least give you an idea of what's involved.
Q:Where to buy cheap solar panels?
Grimcho..I'm going to give you a secret that no-one I know of has ever spoken of..Call Your local railroad maintenance yard and/or your local oil production company..I know your probably in another part of the world where this will not apply but here its like this.. BNSF changes out every 2-5 years their 00w 24v panels...they still have a good 5years of lifetime..Oil companies change them out on their well sites every 2 years 2x 60w 24v (actually they are 2 +2vdc grids series) now if your in Italy sorry this didn't work but if your in New Mexico ..they are in Santa FE...also they have way good batteries that are wet cell and run about 600$ each that they just dump many times on the guy for asking..try it....From the E....
Q:lighting my pond with solar panels?
select 2V, and it will tell you how big of a battery bank and how big of a solar panel you need. For my example, I need a 7ah 2V battery and a 20watt panel.
Q:anybody owns a house solar panel system does it really save you money on electricity?
I'm waiting for the gov't to do right thing and subsidize my purchase!
Q:Is it truE thet solar panels. . ?
They can supply a current on their own, but that is not very useful. A battery allows you to store that current so that you can use it at night or when clouds are blocking the sun. the voltage regulator makes sure they do not provide more power than the battery or whatever else you hook it up to can handle. Most places that sell solar panels will have these items to go with them. You will probably want a battery with a larger capacity than a car battery.
Q:how long does it take for a solar panel to make one watt?
Well, a 5 Watt solar panel running for an average of 2 hours per day, (there will be clouds), will put 5 * 2 = 80 Watt-hours into the battery. Assuming your inverter, (to convert 2 Volts D.C. to 20 Volts A.C.) runs at 00% efficiency, that will only supply power to run the grill for about 22 minutes a day. In the real world, neither the battery nor the inverter will work at 00%, to your actual heating time will be significantly less. If you get about 0 more of those 5 Watt solar panels, that would give you about 50 Watts * 2 hours or about 800 Watt-hours which would more than cover what you want to do. The next problem is getting an inverter which will handle a 700 Watt load. They can be found at auto supply houses and the larger truck stops. (They are popular with semi-drivers.) Note however, that a standard car battery will have to supply about 55 Amps, which means you will have to use some really heavy wire, like # 4 or # 6 welding cables to connect the inverter to the battery to minimize losses. P = 700 Watts E = 3 Volts I = 53.84 Amps R =
