Q:2v about 600ma Solar Panel?
Hey Jeff, what you're talking about is frequently referred to as a, solar battery maintainer. There are lots of places that make and sell them, I have seen them in many auto parts stores and truck stops along the freeways. Go to google and search for a solar battery maintainer, they come is sizes similar to what you are searching for, but it will be difficult to find one that is not over 4 wide. Lots of them are about the size of the top of a shoe box, maybe 2 X 6, and come with a cigarette lighter cord attached. A 2 volt model at 500 ma, or /2 amp, works out to about 9 watts, assuming the 2 volt nominal voltage panel is actually optimized for 8 volts, as most of them are. These devices are designed to sit on the dash board of your car and keep your battery charged if you leave the car for a long period of time, like at the airport for a week in the winter. They actually work for that, we've used one before. What are you planning on doing with it? Charging a battery or running a device directly? Remember if you hook it straight to a device, and the current requirements of the device are less than the available sun will develope with your panel, the voltage may climb to a level too high for your device. If you're charging a battery, this does not cause a problem. Another option is to build your own. It can be a lot of work for just one panel, I've not done it myself, but there are videos on the subject. That device in real goods is a flexible panel, known in the solar world as, Amorphous. They are still a bit experimental, the ones they made a few years ago did not hold up as well as the solid ones, and they are expensive. You can get a /2 amp maintainer for around $25. Good luck Jeff, and take care, Rudydoo
Q:Does a solar panel work on a cloudy day or a rainy day?
This Site Might Help You. RE: Does a solar panel work on a cloudy day or a rainy day? I've heard that solar panels have back-up batteries for when it is cloudy or rainy that day.. is this true?
Q:Why don't scientists use the design of a tree for solar panels?
solar panels do not use generators, but i like your idea, very creative.though i don't see the practicality of this being used commercially, i think it would make a great solar promotional piece though! off-subject, it is time we stop looking at the upfront costs of things and start looking at what the long term costs are. most green-technology, although expensive at first, end up saving tons of resources and actually increase profits of businesses! studies show that people who work in a green building tend to be happier which benefits health, more excited to go to work due to the business's environmental ethics, are more productive because of natural lighting, and are more efficient because more work is getting done. green buildings can actually boost the efficiency of a business! thus saving tons of money and reducing tons of waste. Doesn't this just make sense to you?
Q:Have a 40watt 20volt solar panel, how many watt of inverter do I need?
500 Watt Solar Panel
Q:How do you make a homemade solar panel?
Did okorder.com/ . Possibly this could immediately instruct each and every one!
Q:solar panel webcam?
Q:What are solar panels made of?
Solar panels are slabs of semi-conductor metal. Technically speaking, they are a slab of silicon semi-conductor doped or added with impurities to make it a better conductor. Solar panels could also be made of Gallium Arsenide which is a semi-conductor metal exclusively used in photo-voltaic cells.The silicon slabs are polished and glossed before doping. After processing, for protection, a thin glass layer is embossed on the solar cells slab. Silicon also is shiny and reflects about 35% of sunlight. Hence, an anti-reflective coating is usually applied over the slabs to reduce the amount of sunlight lost.
Q:What should the voltage be on a small marine solar panel?
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:what is one benifit in a solar panel?
what do you want to know ? there is so many benefit of the solar panel , such as no pollution , ETC
Q:i have three 30 watt solar panel and 6 battery cells of 2 volts 550AH. but my batteries are never fully charg?
you need to have a voltage regulator on the gadget. That suggested, i imagine you're literally not giving it sufficient time. The battery might want to convey the voltage all the way down to its element. it is merely you attempt to replenish a huge reservoir with an eye fixed dropper. Bringing the voltage down would not help both. That lowers your ability.
