5 Volt Solar Panel

I have a solar panel that lights some garden lights. However, I'd like to use this to power a small 9 volt device. Will the 4.5 volt panel slowly recharge the 9volt battery, or doe sit not work this way?

No, the charging voltage has to be greater than the battery voltage.

Today we test a small soalr panel I made!

I'm making a USB charger and since I want to also with my iPod I want to make sure that if I buy 5 volt solar panels and wire them in parallel that they won't achieve greater than 5 volts which would fry my iPod.

Have you considered using a small battery in between the solar panel and the IPOD? That would prevent the IPOD from having to absorb voltage spikes from direct power from the panel.

A solar panel's rating is at standard testing...

I have created a solar panel made from copper and aluminum that produces .5 volts. I would like to connect multiple panels and power an LED or something similar. Thanks.

connecting them in series should give you the same amps, but boost your voltage. Most LEDs run on 1.5-3volts.

I think that that solar panel will give 17,777.78 W at standard voltage (110V in the US), which comes out to be about double of what a standard household uses, taking into account efficiency (decrease to 70%) and cloud cover, night, etc (decrease...

I dont understand your 17,777.78 figure.

Anyway, a 400 wat panel is unlikely to b enough to power your home unless your power requirement is vry low.
Those on solar power (off grid) generally start by reducing their power...

better question...
Which one of these are better?

Keep in mind, I am on a tight budget. that is why I am thinking that I might be able

Nata's math is a little off - the units don't work out. If a 12 V battery does indeed have 50 wh of energy in it as he suggests (that sounds right to me), it will take 50wh/1.5w = 33 h. Nata converted to amps and then ignored the voltage rating of...

This is for a highschool science project, and any suggestions would be helpful.
Thanks for the suggestions. I was also thinking of maybe using a small desk fan kinda deal too (probably around 5x5 ish). SO if you have any idea how many solar...

1 pannel is sufficeint to light Torchlight bulb.

Regular Light Bulbs are designed to glow in Alternating Current.

Bulb connected to 100 nos Solar Pannel through a sine wave converter should enable the bulb glow.
