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:what parts and tool do i need to build and connect a solar electric panel to my home
- Dear Matadora, Very good, good, good step to change your home electric supply to solar cell, because in long run, solar cell is cheaper. First you have to consider Power need for your house, eg. 200W, then you go to sellers and choose one with lowest price but best quality. After that you should assemble/attach your solar panel in place that gets most Sunlight, most probably in your roof. Attach them tightly, avoid burglar. Original solar cell current is DC. Current from solar cell placed first in several car batteries, so you could use electricity in night either. After that if your home appliances use DC, you could directly connect your appliances to batteries. But if your appliances need AC, current should be converted first from DC to AC use DC to AC converter. Car battery used to have 2 Volt DC. So if you need 220VAC, after DC converted into AC, then passed through transformer to increase voltage. Thank you very much Matadora.
- Q:Can solar panels be installed on universities or educational campuses?
- Yes, solar panels can be installed on universities or educational campuses. In fact, many educational institutions around the world have already embraced solar energy as a sustainable and renewable source of power. Installing solar panels on universities and educational campuses not only helps reduce carbon emissions and dependence on fossil fuels but also provides valuable hands-on learning opportunities for students studying renewable energy and sustainability. Additionally, solar panels can help universities save on energy costs in the long run, allowing them to allocate more resources to other educational initiatives.
- Q:Can u guys help on how solar panels work and how it generates electricity?(or u can give me a good website that has solar panel info on it)~Thanks in advance!~
- Solar okorder under products that are sorted by watts per area. Also go to wikipedia to get more detailed information on solar cells.
- Q:My solar panel is 24long..It is set at 45deg..the arms are 8quot;long to achieve that angle for winter. I need to get to 7deg for summer..how long will the new arms need to be?..in layman's terms please...thx
- You did not give the details of how the legs are attached to the panel. I did some calculations on my right triangle analysis application. Based on an assumption that the legs are vertical and attached to the bottom of the panel top, i calculated the legs must be 6.97 inches long. This compares favorably with the 8 inches you quoted. t If my assumption is true, the leg length for a 7 degree angle is 2.925 inches. The configuration, if my assumption is correct, will be a right triangle. The hypotenuse (longest leg of the triangle) is the panel length and the vertical legs are the supports. If my assumption is incorrect, edit your question to detail the support /panel configuration. TexMav
- Q:i already have solar/gas water heating, but was wondering if getting solar panels for electricity installed was a good idea.

- Q:Can solar panels be used for charging batteries?
- Yes, solar panels can be used for charging batteries. Solar panels convert sunlight into electricity, which can be used to charge batteries and store energy for later use. This process is commonly used in off-grid systems or to power portable devices and vehicles.
- Q:So, assuming that a solar panel is flush with the ground (i.e. only the photovoltaic side is visible, the other sides are covered by dirt,) what would happen if it was run over by a car? How about an SUV? Would it break?Would the solar panel still generate electricity?
- it would ruin and it ought to nevertheless do power yet no longer plenty yet maximum possibly there may well be no power and plus why might somebody placed a photo voltaic panel on the line? that should in basic terms be stupid.
- Q:want to run 400 watt heater 8 hrs a day how many solar panels do i need and batteries
- Get the rating from the manufacturer, they will give you the watts per m2 of their panels. divide 400 into the rating and will have the total area, then get the area of the panel that physically fits better the project and divide the total area into that of the panel selected, you will have how many panels you need. For the batteries is more complicated because of the available light hours of your location and what time of day are you going to use the heater, to be safe make a bank of batteries to store 600 watts to have a 50% stored power for emergency
- Q:It measured volts before I attached it, and after attaching the voltage regulator device, the voltage dropped down to 3 volts, even when just measuring the difference in the solar panels nodes themselves, suggesting that the entire panels voltage dropped and not just the voltage in the regulator. I tried testing it with a power supply of 7 V 0. A and it works fine, but I don't know why it won't work for the solar panel.
- you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
- Q:Currently being sold today! I know SunPower corp. commercial panels are about 20%.
- 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.
