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.
5. Q: Do you accept custom design on size?
    A: Yes, if the size is reasonable.

Q: Rooftop solar panel (not sure if rubber or plastic?) has leak arising from thin vertical crack in panel about long. Any ideas for repair?Thanks.: bypass the whole panel if you can ( one individual panel of several ) , or bypass that loop in that panel - car part rubber hose clamps

Q: Does anybody know if there are any courses for solar panel installation, and/or what trades you need for this position?: If you are in the UK, then the Centre for Alternative Technology courses (CAT in Wales) have had some great feedback.. .. A lot of companies are actively recruiting and offer training courses as part of their induction. Have a look at the bigger ones recruiting near you.

Q: Can solar panels be used in areas with high levels of dust or sandstorms?: Yes, solar panels can be used in areas with high levels of dust or sandstorms. However, frequent and heavy exposure to dust or sand can reduce their efficiency over time. Regular cleaning and maintenance are necessary to ensure optimal performance in such areas. Additionally, advanced solar panel designs and coatings are being developed to mitigate the impact of dust and sand accumulation, making them more suitable for use in these challenging environments.

Q: Are there any noise concerns with solar panels?: No, solar panels do not produce any noise as they generate electricity from sunlight without any moving parts.

Q: Can solar panels be installed in rural areas?: Yes, solar panels can be installed in rural areas. In fact, rural areas are often ideal for solar panel installations due to the availability of open spaces and ample sunlight. Installing solar panels in rural areas can provide clean and renewable energy to these communities, reducing their dependence on traditional energy sources and improving energy access.

Q: How Much energy does Solar Panel Produce,and How long can Solar Panels go without maintenance.: The available energy is a function of several factors including insolation (sunpower) mounting angle, gathering area, type of cell and conversion efficiency.

Q: I thought that I had a fairly good understanding of watt's law, but i'm starting to doubt myself.If I have a load of 4500watts at 240 volts, how many watts of solar panels do I need, if the solar panels are at 2v?Yes, Yes... I have a charge controller, batteries, etc...So the way I looked at this at first:watts = volts * amps For the load4500 = 240 * xx would be 8.75aFor the power source (each solar panel)00 = 2 * xx would be 8.3a8.75 / 8.3 = 2.25, rounded up = 3So... based on that I came to the conclusion that I needed 3 solar panels...But... then I was thinking. Does it work that way?Or do I need 4500 / 00 = 45, aka 45 solar panels?In other words...If I have a 2v power source, how many watts do I need to drive a load of 4500w at 240v?ThanksMatt: The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.

Q: I live in Los Angeles area, I see the ads that, they will install solar panel for $0. I would like to know what is the catch ?Thanks You.: Sh*t is expensive. I live in FL.....to solar a 500 sq foot house here ...even with the gov rebates and the discounts..etc..etc.. sts the home owner @ $24,000 dollars. They say you will recoup your $$$ in 0 years. 0 YEARS??? The gov should get behind this and make it cheaper...but that will not happen.

Q: Can someone tell me the average savings you get PER solar panel installed? I do not have the money to invest in a bunch of them at once, so I am forced to buy one at a time, when I have the money. So how much can I expect to save after I buy the first one?: No matter what or how you do it it is best to get off coal and nukes. So it cost a little bit of money you are buying 30 years of electric. How much will you spend adding in cost of living increases over the next 30 years? Solar really is pretty cheap if you take the time to do the long term math. If you use your cost at to days rates it does seem like a lot. But if you do the math like in real life with 3.5% compounded cost of living increases per year and 6.5% fuel increases per year. Well, you pay a lot more renting power. One other thing to think about and Al Gore keeps pointing it out is, Will your off spring be alive in 50 years from now if you don't buy the solar panel? Kind of like not going to the doctor because you can't afford the bill. Well I would rather owe a bill to a doctor that I will have trouble paying then not be alive at all to try. If you don't have the money to jump in and go full blown Green you should buy a starter system. You can get a system that can be expanded to 3000 watts (enough to power an energy efficient home). Would cost you about $8000 USD to get started and then you could add three solar modules at a time till you get it up to the 3000 watt max. And even have backup power. Or you could just buy a 000 watt system for about the same price and just add 3 of them over the years. There are many ways to get started. The deal is everyone needs to get started even if it is a small system. If all 50 million homes in the USA would install a small 000 watt system with 4 hours of sun light a day. We would provide (000 watts times 4 hours times 365 days times 50 million homes) 29,000,000,000,000 watts not from coal or nuke plants per year. I wonder if that would help?

Q: i trying to make a solar panel. right now i dont have money to go and buy a copper sheet. so can i make it out of aluminum foil. if there is a way please tell me how. and what do i use for wires. i making this to charge batteries.: Presumably you plan to create a focused parabolic reflector and have it oriented to heat the bottom of a pan. It will obviously need to be larger than the pan in order to gather sunlight outside of the pan's shadow, as well as gather and concentrate enough light onto the bottom of the pan to heat its contents. If you use black paint on the bottom of the pan, make sure it's high temperature paint (available at auto supply stores, often used to paint engine blocks and exhaust manifolds). Yes, a cover on the pan will make it hotter.
