PV Solar Panel 250W High-effiency Polycrystalline

Specifications

25 years warranty
Class-A Grade quality
EL test of each panel
Produced under automatic machines which bought from Germany

Advantages

Reason:

We enjoy exclusive channel to get stock solar panels at more competitive price from Trina,Hanwha,Yingli,LDK,Suntech etc.

These panels are from tier 1 solar panel manufacturers,such as Trina,Hanwha,Yingli,LDK.They are assembled with all grade A materials,only problem is that they has slight appearance defect,but due to their strict quality control,even the negligible defect will lower its grade.so they put these panels into stock.

Quality

These panels adopt all grade A materials,such as solar cell,EVA, back sheet, junction box, glass,frame,connector etc.

They have same electrical performance with grade A solar panels,only difference is the negligible superficial defect.

Q: i need how a solar panel works, if possible make as easy to understand as possible like because of this , this happens and if you could please put a web source you got it from: How okorder /... Use the next page link to flip through the article.

Q: i was looking into making solar panels to reduce my electric bill, but i need to know how to actually hook it up.: Backwoods Home Magazine had a great step by step section in one of their magazines on solar energy, panels, hook-up, etc. You can go to their website, pull that issue up and order the magazine and I believe they offer it on CD. This way you would have a reference guide at the ready when you tackle this project. Godd Luck!

Q: I have 2 solar panels one is 5 watts 2 volts .2 amps or -The other is 50 watts 2 volts 2.6 amps or-Can I ...and what is the best way to hook them togeather to increase my amps being put back to my battery ?? I would be hooking them up to a 7 amp 00 watt charge controllerThe panels are rated 2 volt but the specs say they will produce more whennot connected to charge controllerPlease advise and should I even bother with the smaller panel ?: The answer is that the two panels should be put in parallel. The voltage out will drop to the voltage of the lower panel, but you should get most of the power, if the panels aren't too badly mismatched. I would try to get a multimeter and try to measure the actual current coming out of the panels in full sun. Sometimes the specifications on these smaller panels are very optimistic. If the whole setup is putting out less than 2 amps, I'd say wire the whole thing straight to the battery - little chance of boiling the electrolyte at those currents.

Q: the solar panel works with LEDs, small bulbs,etc but neve with any dcmotor. Please help. I have a science exhibition.: Because its not voltage related its current related. look at the start up values for the motor w respect to current. This will be listed in amps or milliamps. Then cross reference that to the output of your solar panel also listed in amps or milli amps... ;)

Q: Can solar panels be used in areas with high levels of hurricanes?: Yes, solar panels can be used in areas with high levels of hurricanes. However, it is crucial to ensure that the solar panel installation is designed and built to withstand strong winds and other extreme weather conditions. This can be achieved through proper engineering, using sturdy mounting systems, and adhering to local building codes and regulations.

Q: Can solar panels be installed on a university campus or educational facility?: Yes, solar panels can be installed on a university campus or educational facility. In fact, many universities and educational institutions have already embraced solar energy as a sustainable and cost-effective solution for their energy needs. Installing solar panels not only reduces the environmental impact of the facility but also provides an opportunity for hands-on learning and research in renewable energy for students and faculty. Additionally, it can help save on energy costs and provide a reliable source of clean energy for the campus.

Q: We have LED at the output of 40 watts and is used for 0 hours giving us 400 Watts-hr of energy consumed.Rechargable batteries needed are 2 V. 400/2 gives us 34 Ampere-hour battery needed. If we want it for 3 days, It would be 34x3=00 Ah. So the battery needed 00 AhNow how do I select the solar panel which can charge this/these batteries? What should be its rating?: First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?

Q: can i put a solar panel on a projector. if nt wat is a low energy projector that i can watch movies and play games on: Unlikely to prove useful. Solar panels don't generate very much current. You would probably wind up spending several thousand dollars, and wind up with a solar panel array (including batteries and power inverter) that is certainly not portable. You will also need adequate current for your projection source (ie DVD player or computer), as well as sound. By and large, the cheapest projectors require the least amount of power. There is no way around the fact that, for a projector to be practical, it must output out a great deal of light. Adequate light requires adequate current.

Q: Do solar panels increase property value?: Yes, solar panels have been found to increase property value. Studies have shown that homes with solar panels tend to sell at a higher price and faster than those without. Additionally, the potential for reduced energy bills and the positive environmental impact of solar energy can make a property more attractive to potential buyers, thus increasing its overall value.

Q: name things someone could use solar panels for or make with solar panels? (use solar energy i mean?): Solar panels can bee installed into your houses or apartments power box (if it's outside). But Solar panels cost more than $00 so i hope you saved up.
