Led Solar Power

at school im making a lamp which is done but now i need to make it run on solar power. It needs a solar panel, rechargable battery, and LED bulb but i dont no wat type or voltage etc..do i need resistors and if i do wat type? and also wat type of...

The easiest way to power a lightbulb with a solar panel is to keep everything at DC voltage. Get a 12V solar panel, a 12V battery, and a 12V lightbulb. I'm trying to put together an inexpensive solution below.

This LED bulb will plug

My friend owns a store here in Minneapolis called The Green Goober.
Her sign does not light up at night very well, and she needs more light... Shes looking to put up LED lights and solar panels strictly to power them.

Does...

Of course, night lights can only be powered by solar by having batteries to hold the power from day to night. Practically, that means using standard 12 volt panels with a charging regulator. The solar panel is rated in watts, but the amount of sun

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'm interested in purchasing some LED icicle-style light strings to go around the house and was thinking it would be nice if they were solar powered to cut back even more on energy consumption. I've seen icicle-style LED strings with a regular a/c...

Those LED lights use so little power, I'm afraid there is not much to be saved by powering them off solar. If solar was all you had, then it might be worth tinkering, but I'd say just plug them in to the wall, and if you're not using them, turn them

It depends on the type of LED you are using (voltage, colour of light, etc.) You should figure on about 0.05W for each LED you want to use, but check the data sheet for the LED first.

Most solar systems have a battery that is...

I want to make a circuit consisting of multiple LEDs that will be solar powered. Will a voltage or current regulator be useful? What else will be useful in the circuit besides resistors?

A VR is useful if you expect greater-than-design voltage at the source - and your circuit is sensitive to over-voltage. Otherwise it is not necessary. For instance if your solar panel will deliver 12V at 1A, and all you need is 6V at 0.5A, you...
