Q:Charging batteries with a solar panel?
can I use a 2volt .5 amp solar panel on a 2 volt battery in a boat that i use for trolling motor and if I can can I leave it hooked up when using the trolling motor ? Plus how long would it take to charge a half drain battery with this panel??
Q:Charge Laptop with Solar Panel?
humm..... .need HUGE solar panel (alot) 2. wires 3. aligato clips . put the panels on the roof 2. use the aligator clip to clip the wire from the panel to the bars of the pluger of the comp. charger 3.tada mark me best:)
Q:i have three 30 watt solar panel and 6 battery cells of 2 volts 550AH. but my batteries are never fully charg?
Wow I think that your battery are too big or in othercase your solar system panels are too small. But making some calcs if you connect your panels in parallel you will have 30 Amps of Recharge for your batteries. Assuming that your batteries are discharged to .75 V/C you will need at least (. x Ah removed)/Recharge Amps = (. x 550Ah)/30A, that means that you will need 20 Hours to recharge your batteries Literally this is imposible to have fully charged your batteries for a proper application you will need 65 Amps from your panels to recharge your batts in 4 hours or de-rate your batteries to 00 Ah
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:solar panel??????????????
You okorder.com Basically, I wanted to do the same as you but didn't know how. I found this book and it showed me exactly how to do it and for a cheap price too! It's a good guide if you want to save a bunch of money on electricity bills. I highly recommend it.

Q:what are bad things about solar panels?
They require the use of Silicon which requires refining. This process of refining uses non-ecofriendly chemicals. It damages the environment. Solar panels are only about 20-30% efficient whereas coal is around 60-70%. Solar panels require much space for such small output. Do note, that new solar panels are being worked on and that with the correct alignment of solar cells, solar panels may become ~80% efficient, rendering coal useless.

Q:solar panel help needed ?
One square meter of solar panels can produce up to 50 watts of maintenance-free power for up to thirty years. The most common solar panels are for 2 V applications. For sq meter: I = P/V = 50/2 = 2.5 A A single solar cell always produces a voltage of approximately 0.5 volts, regardless of its size. For higher voltages, you have to connect individual cells in series to add their voltages. The larger the solar cell, the greater the current will be. You can also connect cells in parallel to increase current. Hope this helps!
