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: Could you print our company LOGO on the nameplate and package?
    A: Yes, we can do that.
4. Q: Do you accept custom design on size?
    A: Yes, if the size is reasonable.

Q: What is the difference b/w them which one is better .: how much does these pannels way and which are the most efficient?

Q: What is the impact of snow accumulation on solar panels' performance?: Snow accumulation on solar panels can have a significant impact on their performance. When snow covers the panels, it blocks sunlight from reaching the photovoltaic cells, reducing their ability to generate electricity. Additionally, the weight of the snow can put stress on the panels and potentially damage them. However, some modern solar panels are designed with anti-reflective coatings and tilted surfaces to minimize snow accumulation and aid in self-cleaning. In regions with heavy snowfall, regular cleaning or snow removal may be necessary to maintain optimal solar panel performance.

Q: Can solar panels be leased or financed?: Yes, solar panels can be leased or financed. Many companies offer leasing or financing options for solar panel installation, allowing homeowners and businesses to enjoy the benefits of solar power without the upfront cost. Leasing or financing arrangements typically involve monthly payments over a set period of time, making solar energy more accessible and affordable for a wider range of people.

Q: Which of these units determines how much electric energy a solar panel can generate?: For a particular solar panel, you can't choose between the intensity and the power in terms of which determines the energy produced in a given time, because the two concepts are related. Intensity is the power per unit area. So if you have twice the intensity on a particular panel, solar energy is being delivered at twice the rate. However, if you were to compare two solar panels on which the same light intensity was falling, the panel with greater area would produce electrical energy at a greater rate, as power in intensity times area. In that sense, I'd say that the solar power input determines the electrical power output.

Q: I am working on a project and I have to build a house with solar panels. My teacher asked me how would I get solar energy if it is rainy or cloudy? I looked it up but didn't understand. Please help me!!: You okorder /

Q: I know what they do and how they work, but at this point they're expensive, don't always produce enough electricity as needed, and can't be used when there's no sun, as in half the day. Wouldn't wind power seem so more efficient? Or if they do use solar panels, how about putting them in the desert. But I really believe that research money should go to fusion generators since that's the future and the answer to our problems. Which is best in your opinion?: There is not a yes or no answer. But for the majority of the population it is a definite no. Because the energy needed to make a solar panel is more than the energy that a solar panel can return in its life time. so No for cities and urbanized areas because there is already existing infrastructure therefore you'll be wasting more energy getting them installed. And it is better and more efficient to have the more common energy sources for populated areas. However that being said it would be more efficient if you live in a remote area as it would not be worth it to build a huge electricity grid just to power one small house in the middle of no where.

Q: How do solar panels affect the property's community engagement?: Solar panels can have a positive impact on a property's community engagement by promoting sustainable practices and sparking conversations about renewable energy. Solar panels serve as a visible symbol of a property's commitment to reducing carbon emissions and reliance on fossil fuels, which can inspire and encourage others in the community to adopt similar eco-friendly practices. Additionally, solar panels can be used as an educational tool, offering opportunities for community members to learn about solar energy and its benefits, fostering a sense of environmental awareness and collective action.

Q: I need to know how solar photovoltaic panels work. Anyone have a good explanation?: 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: Got a small project here in a remote location. There is to be a 2 volt deep cycle battery, the equipment to be powered from battery and solar panel to charge battery. The 2 volt battery puts out 55 AH. the max constant power draw from the equipment to be powered is 7.9 watts. Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight?And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge?Thanks to all the input!: Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight? Maybe theoretically, but you're going to have very little margin for losses and clouds. I'll bet it has very little power when cloudy. 7.9/30 = 0.26. So at 00% efficiency, you'd need it to be charging more than 25% of each 24 hour period. In a summer with long days and a climate with few clouds, you might make it. But I think you're very close to the edge. And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge? For an ideal battery: time = Q V / P time = 55 A h * 2V / 7.9W time = 83 hours So you've got pretty good margin on your battery.
