Product Description:

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.If you have interest in Poly Solar Panels 250W ,please contact us!
 
Characteristics of  Poly Solar Panels 250W
I.Solar Cell : High efficiency crystalline 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, corner connection. 6 holes on the frame can be installed easily.

Q:Air conditioner 25 volt 5 amps: how many solar panels and batteries to run 24/7?
OK, in addition to the solar panels, you wil need an inverter (DC to AC; 2V t0 20V) capable of delivering 20A continuously and as much as 40A for the compressor starting surge, and a fairly large battery bank capable of delivering something over 2000 watts continuously (losses in the charging and conversion process) as well as the surge. So, if your actual demand is now calculated around 2000 watt/hour, and you need to both run the unit and charge batteries during the daylight hours - and considering that the ideal charging rate for a lead-acid battery is on the order of 0% of its capacity, you will need a huge reserve on the battery section and a huge excess on the solar section to make up for the 5 hours maximum input. So, the average high-quality deep-discharge battery will do about 400Ah @ 2.6V. Which comes to 5040 watts for one hour. For round figures, it will give you 2000 watts for 2.5 hours. You will need a minimum of eight of them just to make your system run for the 9 hours you are anticipating. Given that you do not want to run the batteries to zero each night, a 50% reserve would be a wise investment - comes to now twelve (2) batteries. Now, you will have to make 2000 watts (to run the unit) and also produce and another 8600 (per hour for five hours) watts to charge the batteries for the next night. Again, for round figures, you will need 0,000 watts of solar power, or seventy (70) panels. At ~0 watts/s.f. (00 watts/meter), that comes to about 000 square feet or 00 square meters. Modern non-crystaline panels may reduce this by 20%, or so but no more than that. You will be charging the batteries at roughly 20% of their discharge capacity - which will pretty much cut their service live in half, or so. As the average deep-discharge battery has about an 8-year life span under ideal conditions (and your situation will be far from ideal) you may expect to replace them every four years or so with good care. Much less with no care.
Q:question about Solar Panels?
Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
Q:how do you make solar panel?
Solar panel is a sheet of highly expensive, purest Silicon manufactured in a factory of exceptional killingly stringent specifications. You can't do that as a cottage industry, at least the material.

Q:How many Solar Panels do I need?
Everyday I use ,280 kWh 280 kW-hour / 24 hours = 470 kW WOW, that is a very high power level, most homes use an average of .2 kW. My guess is that you mean you use 280 kW-hour in a year, which comes to an average power of .3 kW, typical. Assuming you get, worse case, 6 hours of sun per day, for the first case, 470 kW, each solar panel generates the equivalent of 250 x6/24 = 60 watts, so you would need 470k/60 = 8000 panels For the second case, .3 kw or 300 watts, divided by 60 that is about 20 panels. Depending on where you live, you could need as much as twice that number. Plus you need charge controller, lots of expensive batteries, and an inverter. The big problem is periods of no sun. If you demand continuous power, and you have a period of, say, 24 hours with no sun because of storms, etc, then the number of batteries increases to the hundreds.
Q:Are solar panels efficiency already calculated in their power rate?
Solar panels are tested in a lab that has a light the produces 000 watt/hrs per square meter. In these conditions your panel will produce 80 watt/hrs. If you would like to know what it does in really world conditions you have to find the sun-hours in your given area. A sun-hour is basically how many watt/hrs hit a square meter in a day. This number changes based on time of year, orientation, and temperature. Here in Fairbanks Alaska if the panel was at 90 degrees facing true south in October (.9 sun-hours) It would produce 80 X .9 X .8 (20% efficiency loss due to wires and controllers) it would produce 273.6 watt/hrs on average each day.

Q:Can I get free solar panels?
Try approaching a few power suppiers to find out if they have any scheme or grants available. Or contact a local DIY store/builders merchants and ask if you can have some panels installed and agree to advertising allowing them to let people contact you for your opinion on the panels.
Q:making your own and installing solar panels. Bull s*** or not?
If you're in Hawaii, number one, be sure to get a solar water heater. Guaranteed fast payback. Now about those kits. Avoid the kind that says you can make your own panels for under $200. Those are scams. If you're in CC of Honolulu, you will not be allowed to connect that kind of panel to your house - it doesn't meet National Electrical Code because it doesn't have a safety rating like UL. There are kits for grid-tied solar that run from $6000 on up. That's the kind that can actually save you money. I don't know whether you are allowed to install it yourself, though. In California, you can, as long as you get the inspection, same as any other building project. In spite of being further south, Honolulu gets about the same amount of sun as we do in San Jose, California. That's because our area is dry, and you have more clouds and rain during an average year. If you're in one of the wet valleys like Manoa or Palolo, obviously the situation would only be worse. But your electric rates are high, so you have a good chance of making your money back. Very few sites are really good for wind turbines. You cannot just put it on your roof in the city - it needs to up high, where the wind is strong and steady. That's why you see turbine mounted on towers. Also, because it has moving parts, it's going to wear out. Finally, you know how cars rust out quickly there compared to the mainland? Same thing with a wind turbine.
