Q:Why are solar panels made from silicon and not magnesium?
One of the primary reasons solar cells are made of silicon is that the bandgap energy of silicon happens to be nearly equal to the energy of visible light, which is the major portion of energy emitted by the sun. Therefore, silicon is the ideal substance to fabricate solar cells with.
Q:its about solar panels?
It depends on what you want to do with the solar panels, Heat your water , heat a pool or spa, or to make electricity to use instead of that supplied by the power company. The first three are fairly easy and straight forward. Depending on the amount of water that needs to be heated, the location you live at in relation to the equator and the location of the solar panels and piping . The panels for this applicatin are 00s of feet of piping that absorbs heat from the sun and circlate it. The panels them selves are sort of inert and can be very heavy when filled with water.. Makeing usable power to replace the power company is a real problem because among other things solar cells create DC voltage. A house runs on AC voltage. So all of the items to heat water still apply, location, placement, etc. But now we have to figure hrs of sunlight the output of the cells running the power to a transformer to transform the voltage from 2 volts DC to 20 volts DC and then running the power thru a converter to change it from DC to AC at each point ( transformer converter ) there is a loss of power do to a change in current. After all of the above if a cloud comes by your power will stop, and at night you will have no power. The fix for that is storage cells AKA batteries which store the power until you need it, like night time. The glamor of a all solar powered home is great,, but it isn't practical. So What to do, You eliminate the battery storage, and also hooking up the power to your home. You feed it right into the power companys wiring and guess what? The electric meter on you house runs back wards your send more power to them during off peak times that your using. For every dollar the meter runs backward you get a free dollars worth when you need it. This is a way of storing the power as credit with the power company instead of batteries Its a lot to understand and I hope I helped
Q:background of solar panel?
Hint: It's behind the foreground.
Q:can i join multiple solar panels?
Maybe. It depends on the panels involved, and what their output is. Not all panels are able to be daisy chained.
Q:How do you hook up solar panels to your electricity?
most of the listings are there to get you to send 'em money. some promise a refund if they don't work. good luck getting your money back. it's not going to happen. last, the inverter, and control to feed power back into the grid are expensive. the utility gets to control what you can use, and most often you have to buy it from them. in Calif, the utility has an interest in good solar installations. they provide power during the time of peak demand, so the utility does not have to build/buy the last, most expensive kilowatt. however, (A) any installation that will be at all useful is large, and expensive, and (B) as with all electronics, next year will be better. i'll probably do it. but not yet.
Q:Linking multiple solar panels?
Solar panels are like batteries, hook them up in series and you increased the voltage, hook them up in parallel and you increased the current. You should review your first year physics notes on the matter.
Q:What minerals are used in making solar panels?
Not minerals. Elements. Silicon. Found everywhere. Group III elements for doping. Group V elements for doping.
Q:is it worth it to install solar panels?
Solar is mroe expensive than just about every other form of generation for a centralized plant, but can still be cost-effective for a consumer living in the right place. This is because while a coal-fired plant may produce electricity for 2-3 cents per kWh, by the time it's marked up to retail, distributed, and taxed to get to a residence, it may be 5 cents per kWh - a figure which solar can match in many places.
Q:2V Solar panel directly to 2V inverter...and restult.?
Those tiny inverters that plug into cigarette lighters are horrendously inefficient, as they assume you have the car's battery and alternator at their disposal. It's possible that the inverter itself needs 50 watts without even attaching a load at the output. Second, many 5-watt amorphous panels are too optimistically rated, and may only deliver 5 watts in the best sun. Given that, the inverter probably failed from undervoltage at the input. This is why there is always a battery connected. The idea is that the battery is charged over a long period of time by the panel, then discharged quickly by the inverter. The panel is probably fine. You can short the outputs, and generally nothing is harmed.
Q:Solar panel trouble?
you don't need a capacitor. You can connect it to a light directly. Capacitors rarely break. You can check with an ohmeter.
