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:Pls is it ok to connect a 0watt and 20watt solar panel together into a charge controller port?
You should specify the controller ratings first. Otherwise it is not possible to answer your question.
Q:Hi trying to learn more about Solar panels!?
solar panels collect the suns energy and turns that into electricity that is then stored in batteries. attached to the batteries is another device that takes the power from the batteries and turns it into power you can use in your house. it is a very expensive power alternative.
Q:how do solar photovoltaic panels work?
Hey E Girl, photovoltiac panels are pretty simple. They start with a solid block of silicone, and shave thin layers off of them, called wafers. Once you have about 72 of them, you take half of them and dope them with boron, then the other half are doped with phosphorous. Once that's done, they take one each phosphorous and boron wafer, and glue them together with a special conductive epoxy glue, and attach a wire to each wafer. When the two glued wafers are exposed to the sun, a reaction occurs that forces free electrons from the silicone particles from one wafer onto the other, and a voltage is generated between them, about /2 volt to be exact. Once all 36 pairs are glued together, they are wired in series, connecting the phosphourous wafer from one to the boron wafer on the next, and so on. If you start with 72 wafers, you'll have 36 pairs glued together when you are done. At /2 volt each, that makes a 8 volt panel, which is used to charge a 2 volt battery. The charging source always has to have a few more volts than the battery. These 36 pairs of cells are then arranged on some kind of back board, glued down, covered with acrylic glass and mounted in a frame. There are some great websites you can go to for more info, I will list some below. Did you know that there are over 00,000 homes and businesses in the US alone that use some level of solar power to operate their electrical systems? That's good news. We actually live in one of those homes, it is powered by both the wind and sun and heated with solar and wood. I hope this answers your question, good luck, and take care, Rudydoo
Q:Do solar panels float?
They'll float if you tie enough hundred dollar bills to them.

Q:what is the volts of 75watts solar panel?
Many of the panels used on homes are designed to produce 2 volts DC. 0 of them wired in a series would produce 20 volts DC. An inverter is used to change the DC voltage to AC. The other aspect of electricity is amperage. With electrical units wired in series the voltage is added. When they are wired in parallel the amperage is added. The Volts x Amps produced will give you the wattage. A wise homeowner will examine their electric bills or the equipment used to determine their demand. They will consult tables that let them know how much sunlight their area receives each year as this will alter the rated performance of the panels. Then they will try and determine how much of the demand they want to fill. 80% may be economical. Then they also want to determine what they will do with excess electricity that may be produced during the summer months of intense sun and how they will supply the shortfall of low sun winter months. From all this they will determine the number of solar panels they need to purchase.

Q:Why won't my solar panels drive a motor?
to do basic electrical experiments with solar panels and motors, it is necessary to have a digital volt-amp-ohm meter sometimes called a DVM (digital volt meter). What is the voltage that the solar panels give when the motor is not connected? what is the voltage when the motor is connected? If the motor resistance is too low, then the solar panels will not be able to supply enough current to run the motor and the voltage with the motor attached will be very low. It might take a bright light on the solar panels or direct sunlight.
Q:Why are solar panels not that efficient?
The latter link has a decent explanation, if not a bit technical: One of the most fundamental limitations on solar cell efficiency is the band gap of the semiconductor from which the cell is made. In a photovoltaic cell, negatively doped (n-type) material, with extra electrons in its otherwise empty conduction band, makes a junction with positively doped (p-type) material, with extra holes in the band otherwise filled with valence electrons.
Q:Is heat a factor in how much energy is gained when using solar panels?
no only the sunlight is used in generating electricity
