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 vehicles?: Yes, solar panels can be installed on vehicles. They are commonly used on electric cars, boats, and recreational vehicles to harness solar energy and help charge their batteries.

Q: Why would someone use a solar panel? Does it have to do with the economy right now, global warming, or what?: The sun provides power where ever the sun shines. That means you can have power without paying for power cables running for miles across rivers and valleys or just out in the middle of nowhere. Or in the middle of somewhere, you can get more or less off the grid (of electrical delivery) and save money and not be a slave to big business. And since the carbon footprint of making power with solar cells is entirely in the making of them and the batteries, it is a cleaner form of electricity. With the batteries needed to have power at night, it can mean that power doesn't fail when the wires go down in the grid.

Q: I have a small marine solar panel on my boat It came with the boat. I want to make sure it is working before I connect it. With a volt meter It is only reading .2 volts dc. I would think it should be 2-5 volts?: Mark, the 2 vdc is pretty typical. Most panels for home use are set up to charge 2 volt batteries, and they are wired for an, open circuit voltage of 8 to 9 volts. This allows it to have enough voltage to feed through a few diodes, perhaps a charge controller and 30 or 40 feet of wire and still have at least 5 volts left over. Once you connect it to the battery the panel will drop to whatever the batteries charging curve voltage would be. If you have a few minutes, I would suggest getting a book at the library called, The Complete Battery Book, by Richard Perez. Just read the chapters pertaining to lead acid batteries, the other discussions on lithium, ni cads and such won't apply to your boat system. If your panel is not large, and it's short circuit current rating in amps is less than 2% of the amp hour capacity of the battery, you can even run the panel without a charge controller. The book explains this as well. There is a great magazine that gets into the nuts and bolts of this stuff, it's called Home Power, you can find it online. You might also find some info at a couple renewable energy websites, I will list them below. Panels are rated in two ways, open circuit voltage, which you measure with a multimeter while the panel is in open sun and nothing is connected to it. The other rating is short cirucuit current, which you measure with an ammeter while the panel is in the sun as well. You connect the ammeter across the output of the panel and let all the power short right through the meter, so you'll need an ammeter big enough to handle more amps than the panel puts out. A 0 amp unit will work for your boat panel. These tests won't hurt the panel, or the meters, we do it all the time in the field, and the manufacturers will tell you to do the same test if you have a problem with a panel and they want to know if it's malfunctioning. You can check one of their websites if you like. Good luck Mark, and take care, Rudydoo

Q: My husband is interested in buying solar panels for the roof and i dont know where to find them.: Buying solar panels can be very expensive, especially for installation. If your average daily usage is 6.6 kilowatt per hour, then you would need a 2 kilowatt system that could generate ten kilowatts per hour in a day. This system could cost between $0,000 to $20,000. Of course, the higher wattage, the higher the cost. There are some alternatives to spending thousands of dollars on solar panels. ) Buy several solar panel kits and link them together yourself. 2) Combine solar with wind power to decrease the number of panels you will need. 3) Build your own solar panels for around $200 each. If you are handy with some basic soldering, then you can make your own solar panels.

Q: I thought they were going to make solar powered cars and solar power plants among other things. It was only nearly 0 years ago that solar power was the big thing. Just curious, why did it die out?: The technology did not die out. It is in fact quite alive and well, and there exist many different manufacturers of solar panels and devices utilizing them. The problem is that the technology has not yet advanced sufficiently to generate large amounts of power with solar panels, at least not with panels of any practical size and weight. You can easily buy a panel which will trickle-charge your car's battery during the day, but nothing that can generate anywhere near the power required to actually move a car's mass at any significant speed. You would need to buy panels with a very large surface area to make any significant amount of power, and these panels would be very heavy and very expensive.

Q: Can solar panels be used in areas with frequent power outages?: Yes, solar panels can be used in areas with frequent power outages. Solar panels generate electricity from sunlight, which means they can continue to produce power even when the main grid is down. However, for uninterrupted power supply during outages, it is important to have an energy storage system, such as batteries, to store excess energy generated during the day for use at night or during power outages.

Q: Can solar panels be installed on airports?: Yes, solar panels can be installed on airports. In fact, many airports around the world have already adopted solar power systems to generate clean and renewable energy. These panels can be installed on rooftops, parking lots, or open spaces within the airport premises, effectively reducing their reliance on traditional energy sources and contributing to a more sustainable aviation industry.

Q: i need to make a mini-solar car which shouldn't cost much. it's for my science project. for now, i just found out how to make a solar panel using copper oxide, but it does not generate enough power to power up the engine of the toy car [ the small engine they used in the toys, like from TAMIA]: There are several types of solar panels. If you mean photovoltaic panels for generating electricity, that is a really advanced project that few amateurs are equipped to do. In the long run, it will be a lot cheaper and easier to buy factory made PV panels. You can try building one by sandwiching an array of photovoltaic cells between a sheet of glass or plexiglass and a sheet of aluminum. Remember that this assembly must be able to withstand great heat, and it must be sealed to make absolutely sure it does not leak.

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: What is the most powerful solar panel made?: Yeah lead acid is the desirable yet once you've a higher image voltaic setup like 200watts or extra you extremely want a cost controller in addition they favor to be vented because even as they're charged the produce hydrogen that once concentrated burns and is no longer good to respire in. the worst section about lithium ion is they imeadiatly commence to decompose once they're used so that they in straight forward words very last 2-4 years the position lead acid can very last over 2 years if good maintained.
