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.

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:Parts needed to build a solar panel?
You're missing a few assumptions: - where on the globe? - how well is your house insulated, how do you plan to heat/cool your house? - why do you insist on power wasting appliances like plasma screens? Usually, unless it's absolutely impossible, a grid-tie-in system is much better than an insular system. You could use the grid to 'store' electricity for those times when the sun isn't shining and as fall-back if your yield isn't quite as good as you calculated. With the battery system, you'll have to specify your reliability requirements. If you want a 00% guarantee that you'll always have electricity, even if the sun is not shining for a week longer than you've planned according to the past weather history of your area, you'll either have to ridiculously oversize your battery (and panel) system, or plan for some sort of backup system anyway. Finally, if you're really planing such a system, you might want to take a look at the fridges and freezers used on sailboats: these use a eutectic cold accumulator, i.e. you 'charge' the fridge when the engine is running (or the sun is shining) and it'll then keep the temperature for another ~2...35 (professional systems) hours.
Q:how many 45 watt solar panels would I need?
I doubt you will be able to get anywhere near the amount of light needed to run anything for 6 hours a day. You will probably need a battery or something as well. At the least, you will need 3 solar panels, but you will probably need more than that in order to charge the batteries to get it to last long enough.
Q:How do solar panel power systems work?
Solar power works by making solar cells of two kinds of glass; one which has been “doped” to have too many electrons, and the other which has been “doped” to have too few electrons. These layers of glass are then glued together with a thin insulation layer in between them. The top layer of glass is the one with too many electrons, the bottom layer of glass has too few electrons, and the insulation allows electrons to pass from the bottom layer to the top layer easily, but not from the top layer to the bottom layer as easily. As photons come flying into this glass sandwich at the speed of light, the photons crash into the electrons in both layers and cause them to start moving. The electrons in the top layer are tightly packed and can’t move much, but the electrons in the bottom layer can move around enough that they end up crossing through the insulation into the top layer. However, because there are already too many electrons in the top layer, the newly arrived electrons have no place to rest. This buildup of electrons creates an “electrical pressure”. Then contacts are glued to the glass top and bottom, and a wire is added to connect the top layer to the bottom, and the electrical pressure which has built up in the top layer now has a way to escape, and the extra electrons which crossed over the bottom to the top can now return to the bottom layer. This flow of electrons from the top layer to the bottom layer is the electricity generated by the solar cell. A solar “panel” is made up of many of these cells wired in series to increase the voltage to make it high enough to do some useful work, such as charging batteries, and many of these panels can be wired together to do such things as supplying power to a building, or even supplying power to the utility grid.
Q:Do solar panels keep a structure cooler?
I asked the same question once to a PV install during a seminar a few years back, and he explained the following: No, PV panels do not reflect or absorb much heat from going into the building below but there is a reason for this: PV panels that reflect / absorb heat produce less electricity. They are designed to Thermally Transparent. Even worse if installed incorrectly without a good angle and air gap to allow the heat to escape the panels will actually trap this heat and increase the interior temperature of the building below! Below is the scientific analysis that is quite verbose but has two nice graphs at the end. To summarize: Adding PV panels, at best, shaded the building enough to reduce the load of the interior A/C unit by .8 kWh/sq-m/year. The electricity generated by the panels was about 356 kWh/sq-m/year. You can see the big advantage of PV panels is to make power, not reflect heat. Proper insulation is much cheaper and will do a much better job. Don’t worry, I was shocked too, but like anything it makes sense after it is explained.

Q:Solar panels........................?
If your purchasing solar panels for a building or colony where a few families live together, the cost of the panels can be distributed or shared. And loan and electricity bill wont be the same. Loan is a one time transaction while electricity bill you have to pay monthly and everytime. You dont have to buy solar panels every month lol. So its a better option to spend on solar panels although it maybe a big amount, rather than paying high bills every month....
Q:How long does it take to charge a 2v deep cycle battery with a 0 watt solar panel?
0 Watt Solar Panel
Q:Why are solar panels grid-like?
Solar cells are semiconductor devices like computer chips. Current manufacturing methods create small squares of semiconductors. Companies are researching ways to make thin film solar cells that can be painted on or manufactured in large, possibly flexible sheets, but so far the technology to do that is still more expensive than making little squares and then assembling them into big panels. That may change in the near future, but I can't be sure.
Q:How to wire solar panels?
You will have to wire them in such a way that provides the battery with the optimal voltage for it to charge, which on a car 2v battery is around 4v. You said you have some background in electronics so this shouldnt be too difficult. You can connect them straight to the battery yes. Like you said, I believe a power inverter from 2VDC to 0VAC would work just fine. PS3 pulls a lot lot lot of current though so it probably wouldnt last too long. Look up the specs for PS3 and see how many amps it is pulling and purchase your inverter based off of that. I remember trying to run an xbox in my car one time and the inverter I had didnt work because of that. Be careful working with batteries, I had one explode in my face about a month ago.. scariest moment of my life! Good luck!
Q:How to hook up a Solar Panel To a single outlet?
That solar panel puts out about amp (in round numbers). If you are talking about a 20vac outlet, you'll have to send the output of the solar panel through an inverter. That brings it up to 20vac. 20 watts at 20 volts means you'll only be able to draw 0.6667 amps. With an inverter at 85% efficiency, you'll only get about 0.4 amps. That would barely light a CFL. 20 watts of power at 7 volts = amp (in round numbers) 20 watts of power at 20vac = 0.6667 amp (in round numbers) Power (watts) = current x voltage. If you increase voltate, you must decrease current to get the same watts. Watts is the common denominator in power measurement.
