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.

25W Polycrystalline Solar Module Made in China

Q: I need to be able to charge a 2v 7amp battery with a solar panel. I understand that the charge controller will keep the battery from over charging/discharging, but what I don't understand is the amps.The solar panel is rated at 5watts.The solar panel comes with a 2v 3amp charge controller but will I need to buy a 7amp charge controller and replace it with that for my battery pack? Please explain. Thanks in advance.: If it is a charge controller that is wired between the panel and the battery only, then a 3A rating is ample. The controller only has to handle the maximum current that the solar panel can output. The panel will have (or needs to have) an open-circuit voltage that is greater than about 4V in order to actually charge the battery, whose terminal voltage will rise above 2V as it charges. The panel's open circuit output voltage typically is about 7V. The 5W rating is at the maximum power point under the illumination of standard sun and at a specified temperature. That maximum power point probably is around 4V, which means the panel will deliver the following amperage to charge the battery: I = P/V = 5W/4V = 0.36A Since 0.36A is well below the 3A rating of the controller, the controller will not be overloaded when charging the battery. Some charge controllers also have terminals for connecting the load that you want to power. If that's the case, then the controller also needs to be rated to handle that load amperage or higher. If you were to connect a 6A load, then you would like to have say a 0A controller. Hope that helps.

Q: I'm about to buy one but I don't really know which one is best for my home.: One will give you enough DC voltage to light a 25 watt light bulb, [ one 45 watt panel is around $400. ] Now if your wanting AC voltage You have to buy a inverter, 5 or 6 deep cycle batteries, a switch Cables to transfer the voltage, a place out side to store the batteries, instalation brackets for the roof A Permit to Install them

Q: Can solar panels be used to power a bank?: Yes, solar panels can be used to power a bank. Solar panels generate electricity by converting sunlight into usable energy, which can be used to supply power to a bank's operations and facilities. By installing solar panels, banks can reduce their reliance on traditional energy sources and lower their carbon footprint. Additionally, solar power can help banks save on energy costs in the long run.

Q: What are the different applications for solar panels for residential use? How many should I purchase if the avg panel produces 80 watts .: Solar okorder

Q: Can solar panels be used in areas with high levels of sand or dust deposition?: Yes, solar panels can be used in areas with high levels of sand or dust deposition. However, regular cleaning and maintenance of the panels may be required to ensure optimal performance.

Q: Can solar panels be installed on art installations or sculptures?: Yes, solar panels can be installed on art installations or sculptures. This allows them to generate electricity from sunlight, effectively integrating renewable energy into artistic designs.

Q: What is the warranty on solar panels?: The warranty on solar panels can vary depending on the manufacturer and the specific product, but it typically ranges from 10 to 25 years.

Q: I got a really great deal on 2 houses because they were fixer-uppers. I'm living in one and the other I'm renting out. However, the previous owner did everything himself in 950 95, so needless to say, things are not to todays standards. Both houses need rewiring (there are no ceiling lights, few outlets, and mine has two old fuse boxes and the other has a breaker box but it pops the breaker a lot). The only reason they are still functional is because both houses use natural gas for water and heat, so otherwise, they electrical work is getting us by, but who knows for how long. I thought that maybe instead of redoing the electric, that I could just add solar panels to compensate for the small electric boxes. Also, since I would have to hire electricians to do all the work, which would be more cost effective (not including the decrease in utilities since I don't pay the utilities in the rental anyways)?: No. solar panels would not solve your problems and are usually not cost effective. Solar panels will not help to compensate for undersized electrical service. You would still have to upgrade the existing service. Once that is done you should have no problems and all the electricity you need would come from your power company. Have an electrician come out and do an inspection and tell you what all needs upgrading. Solar panels would save you money on the monthly power bill but the cost to install them would be higher than your savings. If it made economic sense to have solar power then everybody would be doing it. That's why you see very few houses with solar panels on top.

Q: The colder a solar panel gets the more efficient it seems to be. As the panel warms, it loses some efficiency. Why is this so? Please explain in a way you would expect a high school kid to understand it, as I am a high-schooler and i have to explain this to other high-schoolers.: For water heater type of solar panel the hot panel has more radiation losses reducing the heat available to be transferred to the water. In PV panels it has got to be characteristics of the PV cells. If the conversion efficiency drops with temperature rise then only this can happen. PV=photo-voltaic

Q: I don't want to spend a fortune, maybe talking like over $200 but I would like to power my computer, the monitor, my tv, and a small fridge.I looked up the price on some but it does not make any sense to me because it says that it has reached the price of less than $ per watt but if I look up a 20 watt solar panel it is $560 dollars. Why would it not be $20 because they said $ a watt.Where would be the best place to buy the cheapest solar panels?: The first thing you need to do is look at the power needs of those things. Add up the power (Watts) to run all of those things at the same time. Then you're also in trouble if you plan to run those things when it's not peak sunlight, so you'll need some battery setup. And some appropriate fuses and diodes and a controller of some kind to protect your panels and the things you are powering. It would take a bit of physics and electrical knowledge to do this and do it safely. I built a car that ran off of solar energy in a college project last school year. We had a bank of Kyocera 50 Watt panels that cost 250 each. So, you won't be able to do this for under 200, sorry. If you wanted to spend more I could figure out everything you needed for you, but money will be a problem. And I don't know if it will really be cost effective.
