Q:What do i need to use a 2v solar panel to charge a 6v lead acid battery as i cant find a 2v to 6v regulator?
Yes, certainly. So long as the solar panel's voltage exceeds the voltage of the battery (which is probably going, certainly if it can be a discharged battery, which is lower than 2 volts), then it will recharge the battery. Additionally, a 2 V solar panel can produce bigger than 2 volts. Nevertheless, the rate of charging is more likely to be depdendent on the availabilty of daylight. And of course, the better the capcity of the battery, the longer it takes to cost.
Q:How does a solar panel turn sunlight into electricity?
my theory is that when sunlight hits the panel it excites the electrons from the rays there by making them move more quckly and attract them to a source with less elctrons making the panel positiveli charge and the electron collector negatively charged thereby connecting the negatively charged particles to which ever body it wishes to donate it too thereby causing electric charges
Q:i have three 30 watt solar panel and 6 battery cells of 2 volts 550AH. but my batteries are never fully charg?
you need to have a voltage regulator on the gadget. That suggested, i imagine you're literally not giving it sufficient time. The battery might want to convey the voltage all the way down to its element. it is merely you attempt to replenish a huge reservoir with an eye fixed dropper. Bringing the voltage down would not help both. That lowers your ability.
Q:Making a Charger out of small solar panels?
The first item is whether the psp charger output is ac or dc. IF, AC then you are stuck as the panels put out DC. (Increasing the voltage enough to cover invertor losses is not practical in this instance!) IF DC, then you need to combine panels to produce 2 Amps, after which it is run through the 3 terminal VOLTAGE regulator to limit the voltage to 5v. That is 8 panels in parallel in 2 groups placed in series = 2amps at 8 volts, then add regulator for 2 amps at 5v. (Parallel increases amps, series increases volts.) Total panels required is 6 panels.
Q:Why are solar panels placed on the roof of houses?
The roof receives the most direct sunlight, and the more direct the sunlight the more electricity is produced. I've never seen solar panels located elsewhere on a house, but I have seen some placed in a yard or field.
Q:Where can I find low power solar panels?
My suggestion is to first make sure that your calculator does not also use a tiny button cell. It could just be that the battery went dead. Also know that it's probably less trouble to just get a whole new calculator. If you have the skills to replace the solar cell, I'd suggest first disconnecting it, and wiring a .5 volt battery in its place. If that doesn't work either, maybe the problem is not the solar cell at all, but just its connection, or even a dirty ON button. As for where to get a replacement solar cell, if it were me, I'd go to a dollar store, and see if they have a cheap solar calculator that I could harvest one from.
Q:What to do with a solar panel?
Solar cells convert the energy of the sun into electricity. By using items commonly found in the home or your local hardware store, you can make a solar panel to demonstrate this photoelectric effect. You can also save energy by converting some of your traditional electrical supply over to solar power. Use sheet metal shears to cut the copper flashing in a square or rectangle to fit the size of the electric burner. Be sure to use a piece of copper flashing that is thoroughly cleaned. You may use sandpaper to thoroughly remove any sign of corrosion before proceeding. Place the copper flashing on the electric burner and turn the burner on. You will need to cook the flashing for as long as 30 minutes or more to develop a thick layer of black cupric oxide.
Q:I have 700watts ups and 2V,65amp battary..i want to add solar panel to just only charge my 2v,65amp batt.?
What you are stating is that the battery you have will operate the UPS for about 2 hours before it is drained past the point of no return (technically 2.82 hours, but that would be a dead battery - most well-designed UPS systems cut off when the battery gets below about a 30% charge so that battery is not damaged. Lead-Acid batteries have about a 0%/month self-discharge rate if there is no load connected. The very best systems are as low as 3%, the worst are over 20% - and all at a 'normal' temperature. So, you will need a maintenance charger of about ten (0) watts or so - amp will be more than enough. And about any solar panel will handle that much with the proper charging connection.
Q:solar panels disconnected from battery?
Know that solar panels almost always incorporate a blocking diode to prevent a battery from back-feeding through an un-illuminated panel. Know that solar panels are usually connected to a battery via an electronic switching charge controller, not directly connected. Know that when a solar panel is open-circuited (disconnected from everything) it's terminal voltage will rise to almost twice it's nominal voltage. (22V is common for a 2V panel), unless it is stored in total darkness.
Q:Solar Panel Help Please!?
I will give you the tools to answer your own question. Here is the solar resource map: Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
