Can you connect a solar panel to speakers that use a wall outlet plug, by cutting the plug off and connect copper wire between the solar panel and cord?Confusing i know. I'm trying to connect a solar panel to speakers for a science project.
Leave the two positive terminals connected together.Disconnect the negative leads from each other. Get two amp diodes from radio shack. Connect each diode in series with each negative lead. there is a band on one end of the diode. Connect each diode so that the end with the band is attached to the negative side of each solar panel. Tie the other ends of the diodes together. This will become the new negative end of your solar panel supply. With the sun shining on the panels , you will now measure the voltage from the plus side of the solar panels to the new negative junction. Connect your load leds in place of the voltmeter and enjoy. Without the diodes , each solar cell thinks the other solar cell is the load. In effect each solar panel is shorting out the other. Some solar panels that you buy already have a diode in their junction box connected for that purpose. You need the diodes to provide the necessary isolation between the two panels, then they can both act in parallel to provide current to the load.
Solar panels produce direct current, the wall plug is alternating. You cannot without an inverter. However, electrical devices smooth out this alternating current using those big power adapters and such. If you find how much voltage your speaker requires you should be able to power the amplifier directly with the solar panel, and have the input from the normal source..
NO NO you will cause a fire and lots of damage. Do not play with the power from a wall outlet. Outlets supply 20 or 240 volts AC Your solar panel supplies low voltage (perhaps 2 volts) DC. The two are totally incompatible. Speakers require no power, just the audio signal from a power (audio) amplifier. .
If you mean powered computer speakers, I think you have a chance. They're low power, and often low voltage. What you want is a parent or your science teacher to give you advice. You will want to find the kind of speaker that has a power adapter that plugs into the wall. The power adapter will put out, say, 6 volts at 200 mA. That's what you want to replace with the solar panel, not wire to the part that plugs into the wall.
