FAQ
1. Q: Do you have your own factory?
A: Yes, we have. Our factory located in 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: Can solar panels be installed on data centers?
- Yes, solar panels can be installed on data centers. In fact, many data centers are increasingly adopting solar energy solutions to reduce their carbon footprint and dependence on non-renewable energy sources. Installing solar panels on data centers helps generate clean and sustainable electricity, thereby promoting environmental sustainability and cost savings in the long run.
- Q: Can solar panels be used during a power outage?
- No, solar panels cannot be used during a power outage unless they are connected to a battery storage system.
- Q: What are the different applications for solar panels for residential use? How many should I purchase if the avg panel produces 80 watts .
- Let me start off by saying we (my family and I) live completely, 00% “off of the grid and are completely self sufficient” The house is built utilizing natures natural elements, in the shape of an octagon with 8ft wide arch doors on every wall to catch every angle of wind (typical 4 sided homes have half the chance as one with 8 sides.
- Q: can a small solar panel be charged with lamps?
- That would depend on the frequency that the solar panel accepts and the frequency of light that your lamp gives out. It may or may not work. The sun gives out a much broader spectrum of light, which is why solar panels are much more effective in sunlight. I have seen solar panels charged by lamps, but it usually doesn't work that well and I have never seen it work with fluorescent lighting.
- Q: Can solar panels be used for powering a mining operation?
- Yes, solar panels can be used to power a mining operation. Solar energy can be harnessed to generate electricity, which can then be used to power various equipment and machinery required for mining operations. The solar panels would need to be properly sized and installed to meet the energy demands of the mining operation, taking into account factors such as the required power capacity and the availability of sunlight in the location. Additionally, energy storage systems may be necessary to ensure a consistent power supply, especially during periods of low sunlight.
- Q: i'm talking abt bulk panelling, how many MW do we get from km sq?
- Solar panels are being improved on a continuing basis. Price is coming down and performance is going up. Still, they are expensive. A panel roughly /2 X /2 meter runs about $00. It generates 0 watts of power. To make a panel km square would take 4000 of these at a cost of $400,000. They would generate 40,000 watts or 40 kw or 0.04 Mw.
- Q: Are solar panels fire hazards?
- Solar panels are generally not considered fire hazards. While there have been some isolated incidents of fires related to solar panels, they are extremely rare and typically caused by faulty installations, damaged equipment, or external factors. When installed properly and maintained regularly, solar panels pose no significant fire risk.
- Q: If this was sold back to the grids what would be the profit i would stand to make per day on energy received in these panels? How did you come up with this answer?
- This question is too generalized to answer. Are you australia? If so ergon buys the power back at 45cents a KWH which is 3 times what they sell it for.(this is guaranteed for 20years) We have a 2.4kw system and it will take approx 5years to pay itself off. Once carbon trading is in full swing electricity costs are going to go up by 40%, then obviously it will take approx half the time.
- Q: Here's a little idea I though might help everyone out in Iraq a little: How about if the US mass produces solar panels that are small enough to carry (maybe one foot by three feet) that have a regular power outlet on them to the Iraqis? We could send convoys to the people waiting in line to buy gas and give each person one free solar panel. Why?. A lot of people are buying gas to run generators for air conditioning, not to fuel vehicles. 2. It would help reduce the gas lines if people only needed gas for cars instead of their generators too.3. It would help reduce the fighting over the power grid if people didn't need the grid for their own electrical power.My theory is, once every family in Iraq has enough of these panels that they don't even care about the power grid (during the daytime anyway) it would be much easier to fix the power grid. Maybe these solar panels could even connect to and add to the power grid.
- In oil rich Iraq it would be counter productive to take such an initiative. There is already a huge shortage of solar panels. If you drive the price up more, which you're plan would do, It would just set back their growth in the U.S. and other developed oil poor places. This would hurt us a lot more than it would help them.
- Q: Okay, so I have a science fair coming up soon and I need help with my project. SO - What should I use to demonstrate with the propeller? A toy boat? Plane? And I only have mini solar panels ; so how do I put the solar panels on the toy boat/plane to make the propeller move off of the sun's energy? Thanks. Steps please!
- Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.
