product description

 

The photovoltaic effect was experimentally demonstrated first by French physicist Edmond Becquerel. In 1839, at age 19, he built the world's first photovoltaic cell in his father's laboratory. Willoughby Smith first described the "Effect of Light on Selenium during the passage of an Electric Current" in a 20 February 1873 issue of Nature. In 1883 Charles Fritts built the first solid state photovoltaic cell by coating the semiconductor selenium with a thin layer of gold to form the junctions; the device was only around 1% efficient.

Following the 1973 oil crisis oil companies used their higher profits to start (or buy) solar firms, and were for decades the largest producers. Exxon, ARCO, Shell, Amoco (later purchased by BP) and Mobil all had major solar divisions during the 1970s and 1980s. Technology companies also participated, including General Electric, Motorola, IBM, Tyco and RCA.[16]

Q:Homemade Solar Panel : Hi! guys i want to know what do you think about Homemade Solar Panel?
If you want to make hot water then they are easy to make. Search the web.
Q:Question about using solar panels......?
I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
Q:How to hook up a Solar Panel To a single outlet?
That panel you reference puts out about 20W. @ 8V of DC. You can't wire that to a standard 20V outlet without a battery/inverter unit. Even then, you don't get a useful amount of power. In a full day you would collect enough energy to run a small TV for about an hour.

Q:Need isntructions for solar panel diy?
This is my system: Solar Panelcharge controllerBatteryInverterLights. Keep positive to positive, negative to negative. The solar panel has a cable that has a polarised two pin disconnect (more or less takes care of itself), as does the harness that connects to the battery, a couple of extension cords, and the charge controller itself. The harness in its current install is fixed to the inverter DC in studs, which has a cable that is fixed to the battery. The harness also had a fuse holder and 0A fuse. Except the battery, panel, and lights themselves, all the works are in a mostly sealed box with only panel, battery, and AC cables leaving. The mains voltage lights (about 3x23W CFL) are connected to a power inlet, which is linked to the inverter power outlet with a short cord. The lights are controlled by turning the inverter on or off with its control switch. The inverter is a 400W cheapo, battery 36Ah AGM, panel 20W, controller basic 7A.

Q:_How many solar panels needed to light up a whole house?
this is according to the load, that is to say, how many electricity do you need in one day.
Q:Can I install solar panel straight to battery on my truck?

Q:How much energy would this solar panel produce?
The amount of power and how long a solar panel last depends on the quality of the components and how the solar panel is built. Why have a small vision of solar energy, like charging a battery. There are resourses that can show you how to build quality long lasting panels that could save you up to 75% on your home power bill. Start adding that up. Yea, it is a whole lot of money
Q:how instal solar panel?
There are MANY garden lights with built in batteries and solar panels that you just need to stick in the ground. There are also self contained units that are wall mountable. THAT way there is no need to run wiring, use battery stacks, etc. and will also probably be less expensive overall.
