5.FAQ of Solar Module

1. Q: Do you have your own factory?

A: Yes, we have. Our factory located in Jiangyin city, jiangsu province.

2. Q: How can I visit your factory?
A: Before you take off from your country, please let us know. We will show you the way,or arrange time to pick you up if possible.
3. Q: Do you provide free sample?
A: Usually we do not offer free sample

4. Q: Could you print our company LOGO on the nameplate and package?

A: Yes, we can do that.

Q:how much do solar panels cost?: The silicon ones(last 5 to 25 years) run about $4-$5 a watt the amorphous (thin film) a little less (may last 5-0 years). If you use megawatt hour (000 kilowatt hr) a month you will need at least 3000 watts minimum. Therefore if your electric is .0 per kilowatt hr( $00 per month) the payback is around 25 years once you add the batteries plus inverters(batteries $50-$00 each)(synchronous inverter $3000 to$20000)(ie $5.00/.0=50 months at optimum output).Figure (depending where you live) probably only 50% so break even is usualy about 20 yrs.Ie you pay 20 years electric bill and hope nothing breaks(insurance not included) then you can start saveing money.

Q:Do solar panels require direct sunlight to generate electricity?: Yes, solar panels do require direct sunlight to generate electricity. While they can still generate some electricity on cloudy days or in indirect sunlight, their efficiency is significantly reduced without direct sunlight.

Q:If you were to be asked to write a material(s) report on either -solar panelsor -aircraft fuselageWhich would you choose?well i was asked to choose between these two,so i guess that if i choose what the majority wouldn't, i might just score a little bit higher,what do you think?if you are the lecturer you would want something different right?: Aircraft fuselage. Right now solar panels are all the rage, and there's lots and lots of nonsense written about them. Aircraft design is old technology, but still quite fascinating. Learn about riveting and gluing techniques, the various aluminum alloys or plastics used, and compare the weight of an airplane fuselage with that of a building of comparable size.

Q:I'm looking to mount a solar panel to the top of my 2003 Pontiac Montana and was wondering how i could do it without any screws? Magnets maybe?: In whichever car I'm not using much, I plug in a small solar panel to the cigar lighter socket, and simply place it up on the dashboard. So long as it gets daylight, it's working, it doesn't need full, direct sun. I just slip it between the transmission-tunnel and passenger seat when I get in, and my cars start right on the first turn of the key. It only delivers a very low level of charge, but it's STILL a net-gain, rather than the battery slowly getting a little tired - even the clock in the car, and the armed alarm-system takes SOME current to run, but even the smallest of panels will sort this out for you.

Q:Okay, I think I understand what I'm doing, but I want to set up some solar panels on the roof of my garage, the building that gets the most sun, and I want to make sure all my math is correct in determining number of megawatts per year. However, my knowledge of electrical terms in quite n00bish, to say the least.Here is what I think I should be doing.The solar cells come at .75 Watts average power.I will install 4 panels of 64 cells each, with a total of 256 cells.: For comparison, 36 of these make a normal 2V x 50W panel. Note they are not tabbed. This means you have to find a way to connect them yourself. The tabs are probably spot welded on by the suppliers. A supplier below has kits of these with tabs, as needed to connect them together. These are not suitable for grid connect, because the higher voltage needed makes do it yourself panels a dangerous and litigious thing to have on your roof. Maybe you could buy a smaller pack from the link below to compare tabbed and untabbed and work out what to do. Your power calculation is a bit incorrect because the sun is only present some of the time. The 36 cell module would produce 50W when square on to the full sun. The sun may be out for around 2h a day in some places and times of the year. However it is the equivalent of 5h full sun, because of the changing angle throughout the day. Look this up on the internet for your region. Temperate zones may be a lot less. One pack in your link is 36x3 = 08 cells. Thus 50W per pack x 5h a day gives 750Wh per day and 274KWh/y. In reality it will always be less because of regions, weather, clouds, dust, inefficiencies, aging of cells.

Q:Why can not the solar panel load directly?: Solar panels (also known as solar modules) are the core of solar power systems and the most important part of solar power systems.

Q:How do solar panels affect the property's curb appeal?: Solar panels can enhance the curb appeal of a property by providing a modern and sustainable aesthetic. They showcase the homeowner's commitment to renewable energy, which is increasingly valued by prospective buyers.

Q:Solar panel packages have different levels of power. For instance you can get a kw system but is this kw per hour or day. How does this work?: kW is the unit of measurement used. kWh means you have kW steady for an entire hour. In the case of solar panels, say you are using 00W panels. That means at any given time assuming ample sunlight is hitting the panel, it is producing 00W. You wanted a kW so you will need ten panels at 00W (less or more depending on the rating of the panel) this will give you kW. That means at any given time you can get as many watts as needed up to kW (000W). Say the sun hits the panels for eight hours a day, you will have kWh each of those eight hours, or 8kWh per day. Unless you have a system of batteries to capture unused power, you will only be able to use up to kW (000W) at any given time, any unused power will be wasted. Solar panels alone are not like a generator, they do not slow down or speed up depending on demand. Even with no load on them, they will produce as much power as they are able, and without batteries that power is lost. To simply answer your question, if you get a kW system, that means kW per hour.

Q:How do solar panels affect my electricity bill?: Solar panels can significantly reduce your electricity bill by generating clean and renewable energy from the sun. By harnessing solar power, you can generate your own electricity, thus reducing reliance on the grid and lowering your monthly utility costs. In some cases, solar panels can even result in net metering, allowing you to receive credits or payments for surplus energy that you feed back into the grid.

Q:I have a solar panel I bought for a diy project and it has a small plug on the end of it, but I need to remove this plug to expose the positive and return wires so I can solder a bunch of stuff together. How do I cut off the plug without shorting out the solar panel when I make the cut? Can I just leave it in the dark a while before cutting? I don't think I can remove the wires from the solar panel end before cutting.: A solar panel doesn't store energy. As soon as the light stops, the current stops instantly. If it's a 200-watt panel or more, it won't be harmed by a short circuit, but it might be good to turn the panel over or cover it with cardboard before working on it. The spark can slightly mar the contacts. Doing the work indoors is enough to cut down the current, too. For a 60-watt panel or less, I wouldn't even worry about the spark, the power output is too low to do any damage.
