Q: I am curious about how much of the energy that a solar panel of a given size and capacity will produce in it's lifetime, and what fraction of that energy was required to produce it in the first place?: At present the technology to create silicon solar cells is incredibly energy intensive. It is not logical to compare the cost of oil to the cost of a solar cell because they are not priced according to energy input. Oil has a strong advantage in that it is concentrated solar and geothermal chemical energy that has accumulated over millions of years. The price of oil does not reflect its energy content, but the cost to retreive it. Electrical energy used to produce a Photovoltaic cell is not priced in any proportion to oil. By some calculations it will take about 50,000 KWh of energy produced by the PV cell before it can recover the energy used to manufacture it.

Q: Which is more efficient at producing energy? Reference(s) would be nice, but not required.: Depends on the planet and solar panel. Generally, solar panels are more efficient according to these figures I bumped into. Photosynthetic efficiencies range from 0.% - 8%!

Q: Can solar panels be used in areas with extreme temperatures?: Yes, solar panels can be used in areas with extreme temperatures. While extreme heat can reduce the efficiency of solar panels, modern solar technologies are designed to withstand high temperatures. Similarly, solar panels can also operate in extremely cold temperatures, although their performance may be slightly affected. Overall, solar panels can still generate electricity effectively in areas with extreme temperatures.

Q: Can solar panels be used in areas with high levels of snow or ice?: Yes, solar panels can be used in areas with high levels of snow or ice. However, the efficiency of solar panels may be reduced during these conditions. Regular maintenance and snow removal are necessary to ensure optimal performance. Additionally, tilted solar panel installation and using anti-reflective coatings can help minimize snow accumulation.

Q: 3.8 volts is required to fully charge a battery. But at 3.8 volts, the battery can be overcharged without the use of a controller correct? What if I don't care if the battery is fully charged? In the case of our family boat, I just installed a new radio, so I'm a little worried about power consumption. So now for the real question; If I hook a 2 volt panel to the batteries, do I need to worry about overcharging them? Or will the batteries stop the charging process once they reach 2 volt?I built the panel myself, it's 8 volts at 3.5 amps open circuit. I have tabs at every 3 volt increment on the panel so that I can use less voltage than 8 if I want to power something directly, (ex:2 volt radio)So I'm using the 2 volt tab at 3.5 amps(approx) for a total of approx 48 watts: It is cheaper to have a solar regulator to extend the battery lifespan. A lead acid battery can vent hydrogen if charged too much and run out of electrolytes. The battery would cost more than a $30 5 amp solar regulator.

Q: So you know how the bigger the surface area exposed to the heat radiation means the quicker it'll heat up.Is this what happens with solar panels, they have a large surface area exposing to the sun, so they can get more heat?: Solar panels do heat up. But that's because the radiant energy from the Sun that lies within the infrared (IR) band of energy causes the material in the panels to heat up. And that's the same for any body that has the Sun shine on it. Your face, for example, will heat up while you get a nice tan on the beach. That's due to the heat producing IR radiant energy. Now if those solar panels are supposed to heat buildings etc., that heat produced in the panels when the IR strikes them will be transferred, usually by some fluid, to floors of the rooms to be heated. And as the amount of heat generated by the Sun is proportional to the area of the solar panels, bigger areas of panel will generate more heat than smaller areas. Photoelectric solar panels are another kind. Here the interest is in the visible band of radiant energy from the Sun. Heat, from IR, is still there, but it is not the product sought by PE solar panels. The visible light photons knock off loosely bound electrons from the photoelectric material (typically silicon based) and those electrons are siphoned off as current. That's where the electrical power comes from for buildings using PE solar panels to provide their own electricity.

Q: i have a 50 watt 2 Volt solar panel..Will it can switch on directly a car head light on a sunny day??? How much head lights it can support on a bright sunny day??? if its cloudy then can it run a single Head light???? i have no batteries just want to connect a car Head light directly to solar panel.: Indestructible okorder /

Q: I want to build a standalone wifi repeater -- powered by the sun. The problem is how much solar power and how big of a battery?net draw 4.5v @ 0.66A with loadnet draw 4.5v @ 0.60A no loadI'm assuming the best choice would be a 6v battery with a a couple diodes in series to induce ~.5v drop. Then, I need something to charge it -- I found 2v 6w solar chargers in the automotive section of Sears and 6v 2w solar chargers in the marine section of Dick's Sporting Goods.How many solar panels and what capacity batteries should I use? Is this the best method or should I use a voltage regulator and go with 2v batteries?I need this to be as cheap and simple as possible...: You won't get very far with THAT lash-up. First of all.. WHY would you want to use diodes to drop the voltage.. they DRAW CURRENT and that is something you don't have to spare. That draw of (660 ma) comes out to just under 3 watts. You DO KNOW that you can get that 4.5 Volts by driving a NAIL into the THIRD CELL in a 6 Volt wet cell battery... right? and for what you are doing, you have more current available with a 6 volt battery than a 2 volt battery. Anyway, you could use two 6 Volt batteries and tap them at the 4.5 volt point then tie them in parallel, but you could still use the 6 volt solar panel to charge them. Trying to use an inverter is just an exercise in futility.. With TWO of the LARGEST DEEP CYCLE BATTERIES you can buy at AutoZone running in Parallel and being charged by solar panels.. if you hook a 75 watt inverter to them, they will go flat in about 4 hours of use during the night. This is not rocket science. Back when cars were changing over from 6 volts to 2 volts, I powered up more than one 6 volt car radio off a 2 volt battery... when you grow up as poor as I did.. you get inventive. I later used the same trick on the 24 volt electrical systems the Jeeps were using, to power up clandestine repeaters in places where no repeaters should have been. About 25 years ago I was living in the Denver area and built up a 0 watt 2 meter repeater on a split channel and took it up to Mt. Evans during the summer and hid it in a pile of rocks. I used tone control, so we were the only ones using it and, as I said, It was a split channel.. so it wasn't on a regular repeater channel. That thing was still running when I moved from the Denver area about 3 years later and for all I know, It's still up there on Mt. Evans (find the Brittlecone Pines and look towards that small peak about a mile to the west)

Q: I need to know where I can buy the parts or find them as scrap to make my own solar panels. Is there a cheap way of buying the panels or can I make them myself.: Build okorder /

Q: okay so my teacher is trying to install a solar panel but we have a problem we don't know where to ground it because it will be a movil house. guys do you have any ideas?: Typically you mount it with the frame as a ground and you ground the frame with a wire or cable tied into the ground when the mobile home is parked.
