Poly Solar Panel 290W A Grade with Cheapest Price


Product description


60 cell multi-crystalline solar module. 40mm natural anodised frame. IP65 rated Jbox, 1m solar cable and a pair of MC4 connectors.TÜV SÜD,SABS ISO 9001:2008 certified.

Nominal voltage refers to the voltage of the battery that the module is best suited to charge; this is a leftover term from the days when solar modules were only used to charge batteries. The actual voltage output of the module changes as lighting, temperature and load conditions change, so there is never one specific voltage at which the module operates. Nominal voltage allows users, at a glance, to make sure the module is compatible with a given system.

Open circuit voltage or VOC is the maximum voltage that the module can produce when not connected to an electrical circuit or system. VOC can be measured with a meter directly on an illuminated module's terminals or on its disconnected cable.

Solar panel conversion efficiency, typically in the 20 percent range, is reduced by dust, grime, pollen, and other particulates that accumulate on the solar panel. "A dirty solar panel can reduce its power capabilities by up to 30 percent in high dust/pollen or desert areas", says Seamus Curran, associate professor of physics at the University of Houston and director of the Institute for NanoEnergy, which specializes in the design, engineering, and assembly of nanostructures.[16]

Product feather

solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.

A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricityin commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q:Are solar panels worth it?
There are two officially advanced desert storm offices with true solar equipping. The systems are both from Nasa type scientists both private property sales. The use of California for the study is because it requires 30 hours per month to keep the satellite sector in alignment. The owner was very specific to each company that all uses had to have junior sim companies for wider availability. The fact remains solar energy is magic, cost of a large ranch in the original maker was reduced with larger needs like barns, greenhouses, spas, and guest cabins by 78%. An average house would not save. The technology best junior designers is around 5000 and will save 25,000 in some high cost locations per lifetime.
Q:What exactly is a solar panel?
A solar panel (photovoltaic module or photovoltaic panel) is a packaged interconnected assembly of solar cells, also known as photovoltaic cells. The solar panel can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications.
Q:Are solar panels affordable?
solar panels take about 5 to 20 yrs to break even. for the average home
Q:How can you get affordable Solar Panels?
you okorder.com. all you have to do is watch the video.
Q:Solar Panel costs and sizes?
Take a look at the website from Retscreen International. This is a site sponsored by the Canadian government and they have everything that you will ever need to know about renewable energy. Download the free software and then feed in the position of your school (GPS Coordinates) and some data about energy useage. It will then link to the NASA websites to tell you the weather and work out what size of solar panel you need, what direction it should point and what angle it needs to be mounted on. I've used it for the UK, Afghanistan, Iraq, Jordan and other countries - It's brilliant - and its free. It also links to manufacturers websites and so gives you costings. Use this and you are guaranteed to be top of the class
Q:solar panels on projectors?
Unlikely to prove useful. Solar panels don't generate very much current. You would probably wind up spending several thousand dollars, and wind up with a solar panel array (including batteries and power inverter) that is certainly not portable. You will also need adequate current for your projection source (ie DVD player or computer), as well as sound. By and large, the cheapest projectors require the least amount of power. There is no way around the fact that, for a projector to be practical, it must output out a great deal of light. Adequate light requires adequate current.
Q:Solar Panels ????????
It means that it will deliver 00 watts of energy. Assuming correct voltages, etc. you could connect a 00W incandescent lamp and it will work just fine. So it is the instantaneous output of the panel. Storage is more typically measured in the watt/hour manner - identifying capacity rather than immediate availability. If you have 000 watt/hours of stored energy then you can run your 00W lamp for 0 hours - or two 00W lamps for 5 hours. See? It's simple.
Q:solar panel regulator?
wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
Q:solar panels on housing developments?
Solar Panels in housing developments is not being used because it would add $25,000 to $40,000 to the price of the home. Most people in the USA don't understand that after a few years the solar electric panels will start paying them back. It is not just the upfront cost. People would rather spend that 40K on somthing smart like a new corvette. Which has no pay back at all then something stupid like solar electric and helping themselfs or the rest of the world. So if the builders were to add them to the house people would just buy from another builder and the one adding the solar roof tops would just go broke. The State would have to find a way to credit the buyer or buider enough to make it worth it. Is it not more fun to spend millions on finding out where Anna Smith is going to be barried? Or maybe billions on top of billions on War? If we had spend the money on solar that we have spend on Iraq alone we could have put solar on every roof top in the whole USA and had few billion left over. Think about it.. 200 million people in the USA with three to a home would be 66 million homes. It would have only cost 528 billions dollars to put a kWh Solar Electric system on each house in America. But that would be stupid. War makes more money. We don't want Exxon to go broke do we?
Q:What is the best solar panel?
your initial outlay for a solar panel is very large in terms of output.......somewhere around $4 a watt......ie you want a panel that will run a 00 watt lightbulb? $400.00 please. enough panels to collect enough energy to recharge a battery bank to run the house overnight? well, I've been doing a lot of research for my condo project in St Thomas and it comes out to 0-20,000 US $ for a bedroom apartment. Now, after about ten years you have made your investemnt back.... and there are a lot of government rebate programs that lower the cost.. what I have found is solar is nice, but depending on how far north you live you may only have 4 usable hours of light a day. you may very well be better with a wind generator.wind blows all the time after all...Bergy and SouthWest Windpower make two good small home units...start there
