4.FAQ:
We have organized several common questions for our clients，may help you sincerely：
（1）What price for each watt?
It depends on the quantity, delivery date and payment terms.
（2）What is your size for each module? Can you tell me the Parameter of your module?
We have different series of panels in different output, both c-Si and a-Si. Please take the specification sheet for your reference.
（3）Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?
Actually we are only manufacturer of solar panels, but we could try to source them for you in China if you need. We could provide you an optimal system design to instruct you how to install.
（4）Do you have the CE, TUV, UL Certification?
We’ve already passed all the tests, and any certificate is available.
（5）Have you ever sold your products to companies in my country?
Of course, we have customers in all general PV markets, but I think we should expand our market share along with the market growth.
- Q: I'm thinking of having solar panels to generate electricity. The drawbacks are that I'm afraid if it needs repair, I won't be able to find anyone. Also I'm afraid that the roof is not very accessible. If it is a new house, should the roof have a roof hatch? What can make the system not work?
- Modern solar electric panels rarely fail. Because of this, if you would be installing them over a roof that only has a few years left on it, it would be better to redo the roof, first. In the unlikely event that a panel needs to be changed, this can be done in 30 minutes or so, because the panels are mounted on racks, with everything simply plugging together. I have never personally seen a solar installation go bad, but from what I hear, the inverter (a box that goes in next to your electric service panel) is usually what burns out after 5 years, assuming the install was done right in the first place. If you were to call roofers to repair your roof, they would somehow be able to get to your roof, by ladders, or a special truck. Solar installers use the same kind of equipment. They won't have a problem getting up there. A solar electric system is actually a very straightforward thing. No matter who installs it, if there is a problem, another installer should be able to diagnose and fix it.
- Q: Can solar panels be used to power a public transportation system?
- Yes, solar panels can be used to power a public transportation system. Solar energy can be harnessed through photovoltaic panels and converted into electricity to power electric buses, trams, or trains. This renewable energy source can significantly reduce carbon emissions and dependence on fossil fuels in public transportation, making it a more sustainable and environmentally friendly option.
- Q: Hi, I have in my sailboat 2 2 V batteries. I would like to buy solar panel(s) in order to recharge them. As i am in mexico and there is always high sun . i think it is a good idea.Usage of the batteries is very light . I have found 5-2V pannels with 80mA that fit in the sailboat. I want to know if and how i can have like 5 to 0 of them set together to charge the batteries and what other material would i need.also, i would like to know what happend if the pannels only send on 5V in a 2 V battery? Is it still charging but on 40 % of the capacity a 2 v pannel would charge or its just not doing nothing ?
- 0 of the panels wired in parrell will give you enough power to trickle charge the batteries. You will need a charge controller to prevent a overcharge from damaging your batteries. A panel array that is rated at 2 volts actually puts out a unregulated voltage up to 2 volts. I have bought some charger controllers from OKorder at good prices. They will also prevent the discharge of your batteries at night or when the panels are in the shade. If the panels only put out 5 volts they will not charge the batteries. Check each panel outside in the sun with a DC volt meter for proper operation before connecting them.
- Q: Do solar panels require a specific orientation or angle for optimal performance?
- Yes, solar panels generally require a specific orientation and angle for optimal performance. The ideal orientation for solar panels is facing south in the Northern Hemisphere and north in the Southern Hemisphere to maximize exposure to sunlight. Additionally, the optimal angle of tilt varies depending on the latitude of the installation site to maximize energy production throughout the year.
- Q: Can solar panels be installed on flat surfaces?
- Yes, solar panels can be installed on flat surfaces. However, for optimal performance, it is recommended to tilt the panels at an angle that allows them to capture maximum sunlight.
- Q: i have a 2v 2a solar panel that i want to use to charge a 2v battery .Have found out that i need a charge controller so i don't over charge the battery.I have found a cheep one its 2v but 7a will it still work ?All-so im planing on running a 2v water pump off the battery with a timer,its for watering my garden.Will the timer have to be 2v as well ?any help on this would be greatly appreciated thanks .
- The charger will accept whatever current is necessary from the solar panel up to 7A. It's not like the solar panel will force 2amps into the charger/battery -- the charger will control the current going to the battery. I question whether or not the 2V panel will actually charge the battery, though, because in order to charge a standard lead-acid 2V battery you need to have about 4.5 volts applied to the terminals. Perhaps the charger has a boost circuit -- I don't know without looking at it or knowing the brand/model number, etc. The timer must be 2VDC, but, if you only have a timer that is rated for 20VAC, you can buy a small inverter that will take 2V and supply the necessary 20VAC. An inverter rated for 20 to 50 Watts should be sufficient. These usually cost under US$25. .
- Q: Can solar panels be installed on water bodies or reservoirs?
- Yes, solar panels can be installed on water bodies or reservoirs. This is known as a floating solar power plant or floating photovoltaic system. It involves placing solar panels on floating platforms that are anchored to the bottom of the water body or reservoir. This innovative approach allows for the utilization of otherwise unused space, reduces evaporation, and provides cooling benefits to the solar panels, increasing their efficiency.
- Q: How about using Solar Panals to provide the electrical power to separate the H2 from the O? H2 would be fed into the engines carburator like a gas/air mixture ratio, but H2/air mixture ratio instead. How would you control the exact measurements?
- It's a great idea, but there are problems. The first is that hydrogen is very difficult to control; it is a small molecule, and very slippery. It is difficult to handle from that perspective; Teflon tape and other common plumbing techniques just don't cut it. Secondly, once you have the hydrogen, you'd have to compress it in order to put it into a cylinder of some sort. This takes electrical power, and in turn is wasteful. Compressed hydrogen storage has is own risks, including hydrogen embrittlement, and the peculiar nature of hydrogen (including having an invisible flame, and a remarkably wide flammable range) makes it quite dangerous. After all, relatively safe products such as propane gas and butane lighters- well-established and very common- are surprisingly dangerous, causing injuries and fatalities each year. In order for something that is more dangerous (hydrogen) to come to market as being a hydrolysis product, either the products will have to be home-made (and therefore more dangerous), or very expensive.
- Q: Just curious.
- Since you said does instead of do I think it would be fruitless trying to explain it...
- Q: Can solar panels work at night?
- No, solar panels cannot work at night as they rely on sunlight to generate electricity.
