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 used in areas with high levels of sand or dust deposition?
- Yes, solar panels can be used in areas with high levels of sand or dust deposition. However, the accumulation of sand or dust on the surface of the panels can reduce their efficiency over time. Regular cleaning and maintenance are necessary to ensure optimal performance in such environments. Additionally, certain design features, such as tilt angles and surface coatings, can be incorporated to minimize the impact of sand or dust deposition on solar panel efficiency.
- Q: I'm re-doing my roof. Is it workable?Can I get a government grant or something to put solar panels on my roof?I know they did something like that for windows.
- solar panels are only about 20% or so efficient right now but you get great tax break in the US --- mostly.. wish you well... ps not that cheap but most companies installing these systems will supply with all grant papers for free.
- Q: Are solar panels durable?
- Yes, solar panels are durable. They are designed to withstand various weather conditions, including hail, snow, and strong winds. Additionally, most solar panels come with warranties that guarantee their performance for 25 to 30 years, indicating their long-lasting durability.
- Q: I have a 2 volt deep cylce Everstart battery with 845 cranking amps, and a Grape Solar GS-S-250-Fab5 250-Watt Monocrystalline Solar Panel . I use them to power a 48Flat screen TV, a Roku, my 65 watt consuming MacBook Pro, and a 65 watt Fan.I know from previous experience that just the battery, an inverter, and the fan, that the fan will blow for 0 hours straight.Should I really be concerned with a Charge Controller?
- Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.
- Q: I just moved into somewhere with solar panels but don't really understand them...all I know is that they heat the water.Do I still have to turn the hot water on with the solar panels or do they heat it automatically or do they store the energy until I turn on the hot water?!
- Custom solar-heating systems are unique. Does yours have a circulating pump? Does it have a storage tank? Is the fluid that goes to the panels separated from the household water and transfers heat through a heat-exchanger radiator, and the fluid has antifreeze in it? If it does, is the antifreeze of the variety that won't poison your family if there is a leak? Does your system have a thermostat-controlled pump that turns on when the water in the panels are hot? Does it have a limit-thermostat to turn off the pump when water in the storage tank is hot? There are many more variations to operation of solar-heating panels. Find out who designed it or who knows how to operate it and ask them.
- Q: What controllers and all that stuff do I need for these solar panels. Oh and the the batteries will be rigged up to a big electric motor so please leave information on how to wire the batteries to the motor...THANKS!!! 0 POINTS!

- Q: im making an energy efficiant house for science class and i need to price the house. im putting solar pannels on the roof and would u please tell me how much they are per like 2 sq. feet of a pannel?
- You are way out of your depth if your report for science class is supposed to be knowledgable. First of all, Solar panels alone will NOT be enough to charge the battery bank, which you don't even mention in your quesiton. Secondly, the only way to have a usable 2 VDC system is to use a wind generator to keep the batteries charged to capacity and, as a plus, they will work at night. A 65 Watt ARCO Solar Panel is about $300 and you need to figure your power by the Wattage Rading for the particular panels . You also need to add in the cost of a 2VDC to 0VAC invertor, monitoring panels etc.... AND... just how big is the ROOF of the house you are planning to use.? This is an area of involved study and it's a bit more than what you are imagining for your high school science class report.
- Q: Can solar panels be installed on concert venues or music festivals?
- Yes, solar panels can be installed on concert venues or music festivals. In fact, many venues and festivals are increasingly adopting solar power as a sustainable and renewable energy source. Solar panels can be installed on roofs, canopies, or even on the ground surrounding the venue, providing clean energy to power the event and reduce its carbon footprint.
- Q: all i want to do is provide enough electricity for 2 fluorescent bulbs i was looking at some 80 watt panels how many of those would i need and what else do i need for storing the electricity for use at nite? and how much would it all cost?
- The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
- Q: Can solar panels be used for powering agricultural equipment?
- Yes, solar panels can be used for powering agricultural equipment. Solar energy can be converted into electricity, which can then be used to power various agricultural machinery and equipment such as pumps, irrigation systems, electric fences, and even small tractors. This helps reduce reliance on traditional fossil fuels, promotes sustainable farming practices, and can save farmers money in the long run.
