Q:What would happen if a car ran over a solar panel?
Even running over one with a mountain bike will break the pannel. Now depending on how you run it over it might still produce power. If the circut is unbroken then what ever cells were not shattered and severed will work but most likely at a lesser capacity.
Q:Solar Panel Batteries?
Sorry, I can't really help you :[ Google some stuff, look for help from people who know what to use. If I were you, I'd go with the lead-acid battery.
Q:How can I power 5v or .08 amps in a remote loaction via solar panel.?
First things first. 5 Volts @ .08 amps would be .2 Watts. therefore you would need at least the same amount from a solar panel to replenish the batteries. But what puzzles me is the notion that plugging it in a wall outlet ? If you use 20 V @ 0.08 then the power consumption is 9.6 Watts And what is a meraki wireless repeater? I never heard of one. I'm a FCC licensed Ham and have some idea what is available. If you need 5 volts DC, you could use twelve Ni-cads in series and just keep them trickle charged with the solar panel That would make it compact. If you were to use an automotive battery (or motorcycle), then you would need a DC/DC converter.
Q:what is solar panel? full description needed?
Solar Panel is a broad term for gathering energy from the sun. It could be Photo Voltaic, or Thermal. A thermal panel is often used to heat a swimming pool. It consists of plastic tubing laid out in a black case to directly heat water or oil. The Photo Voltaic panels are batteries that convert photons into electrical potential and current.
Q:Will a 3w Solar Panel Charge A 55ah Car Battery?
I don't think so, but if it did, it would take a very long time. You need enough wattage or amps to push the power in the battery and 3w may not be enough. You would be better off with a small 2v battery, maybe the type they use for emergency lights. I would use a sealed battery for this type of setup because car batteries are designed for heavy charging with alternators from 60 amps and up.
Q:electronics help solar panel?
[] Use it to charge 4 pieces AA cell ( connect in series to make 5V battery pack ) for 0 to 4 hours. Good for cell rated 600mAH ,2000mAH,2500mAH. [2] Cannot increase current. Buy some more this panel and hook them together in parallel to increase current. You need at least ten pieces to make current reaches .6A to light up some 6V bulbs.
Q:Solar panels for home info?
It depends on what type of solar panels you are looking for. PV panels for electricity or heating panels for hot water. For more info about hot water heating panels, check out my source.
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:lighting my pond with solar panels?
You can get 6V cells and SLA batteries. You would get a panel and batteries suitable for the lights you get though. Depending on what you want to do, you shoud look into LED lighting, which is more efficient than incandescent. You do not want to drain your battery flat. Rather you want to draw only 2/3 of its capacity of so. You would find the lights you want (likely 2VDC), and add up the current they draw, and get a battery that would supply enough capacity (in AH, which is amps time hours) for a couple nights use (to account for weak solar days), and a solar panel to charge two days of use in one good day. You would use a charge controller so that the solar panel does not over charge the battery, and some sort of dusk timer to turn your lights on at dusk and off several hours later.
Q:Can you connect a solar panel to a regular plug, using copper wire?
