Product description

A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.[2] It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.

Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.

 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:Linking multiple solar panels?
No problem linking them in series.
Q:What exactly is a solar panel?
they are a long way from producing enough electricity to keep a cell phone charged. but maybe some day in the future. but as our culture is recognizing the importance of solar electricity they are starting to mass produce solar panels and creating major problems of wast when they get old and stop producing electricity. they are super toxic and shouldnt be thrown away. they will prob have special places set of for those in the future.
Q:Do solar panels float?
I've had people banging on my door to install them unfortunately i can't test the theory The offer came between the government sign-up of insulation where the ensuing deaths of several installers halted the program and the Queensland floods - not a floating panel in sight!
Q:How do you make your own solar panels?
Well, I can think of a couple places, that you might have got that info from. There are several plans on the net. to build solar heaters from auxillary window units, to full thermal mass walls, with stacked 55 gallon barrels painted flat black, and filled with water. Old Mother Earth News magazines are a great source for these, but its basically sittin a closed box in the sun. . . Not very sexy, and not exactly Rocket Science, I'm thinkin what your askin about is Photovoltaics. Basically a reaction in a silicon chip, that pushes an electron toward the grid. Electiricty producing solar panels, are beyond the capabilities of a single person, however, they''re are (or were a couple months ago). a couple retail sales OKorder stores, scavaging they''re broken panels, cutting out the individual single cells, and then selling them as kits, with instructions how to wire, solder and assmeble working cells. Thats probably what your hearing about, and I think they ended up being about /2 price what they''re new ones sell for. Then you can move on to the bottlemeck problem, that all the green alternative ideas run into . . .How to store it Good luck, and Good Hunting . . Tim
Q:Solar panel question?
4 in series for the 48V, a rack of 3 sets wired in parallel to give the current. (total of 2 panels)
Q:what materials would you use and how would you construct solar panels enough to run a household?
If you think that a solar storm is going to knock out most power utilities in that time, what makes you think that your solar panels will not be affected as well? The cost to even come close to light up half your house will be prohibitive and will take at least a decade or 2 to just break even on your original costs. May want to do a little more research on your 202 storms. If you are concerned about the power going out for a while, then you better check at what else may happen.
Q:how to make your own solar panels ?
If okorder.com/ . Beware of anyone who makes claims you can save tons of money by making your own panels. Those are scams. It's possible to save money with solar, but not with homemade panels.
Q:i have three 30 watt solar panel and 6 battery cells of 2 volts 550AH. but my batteries are never fully charg?
Wow I think that your battery are too big or in othercase your solar system panels are too small. But making some calcs if you connect your panels in parallel you will have 30 Amps of Recharge for your batteries. Assuming that your batteries are discharged to .75 V/C you will need at least (. x Ah removed)/Recharge Amps = (. x 550Ah)/30A, that means that you will need 20 Hours to recharge your batteries Literally this is imposible to have fully charged your batteries for a proper application you will need 65 Amps from your panels to recharge your batts in 4 hours or de-rate your batteries to 00 Ah
Q:Opinions on Solar Panels?
I have a boat in a sunny place and four 80 watt panels. These will run my fridge Tv and a few LED's. I still have to run my engine for hot water and washing machine. My Batteries only last a few years and are a real pain. I go on the mains when I can to get the batteries topped up. The panels are ok if there is nothing else, they are not the answer to the future of energy supply. There is also the moral aspect of the feed in tariff. For the rich to load their electricity bill onto the less well off is not acceptable and those panels on the roof tell all your neighbors that you are doing it. That will show a greedy selfish attitude. If they are any good why don't the power companies buy them and save buying coal?
Q:I would like some info on Solar panels and Wind Generators...please?
You may have to put a snow roof over the wind generator to keep it working. A solar hot water system might be hard investment where you are but it could work if it's designed right. Check out the solar companies in your area for ideas.
