Lighting – High Tech With Solar Power
From the first time I saw, first hand, a solar cell making electricity, I was hooked. It was magnetic. I was going to have one, making electricity for me, one day. I didn’t get around to trying it, until about 1979. I ordered $400.00 worth of solar cells from a company in California. I made a makeshift solar panel with them, which worked for a while.
A solar cell reacts with sunlight making a positive and negative charge. When you link the two charges by attaching a wire to both ends of the solar cell, charged electrons move along the wire, and an electric current flows. When the cells are joined together, to increase the voltage and amperage, you have made a solar panel. So all this makes the electricity your light uses.
Once you have the electricity, you have to store find a deck builder it somewhere, or use it right away. Since the whole point of a light is to use it in the dark, and solar panels only work in sunlight, you need a battery, to store the electricity until you are ready to turn the light on.
To keep the electricity in the battery while the solar panel is connected, a diode is used. A diode is an electronic device which only allows direct current to travel in one direction. If the current tries to go in the other direction, then the diode stops it. This happens when a big dark cloud moves in front of the sun. Your panel makes so little power the battery has more voltage push, than what is coming from the panel. So the voltage from the battery tries to send current out from the battery. We want the battery to charge, and not waste the electricity until we turn on the light.
When you switch your light on, you are using the power from the sunlight captured during the day time. The advantage of using compact florescent light bulbs is that they are very energy efficient, using little electricity, and giving out the same amount of light used by a 60 watt regular light bulb. You make your own power and don’t care if the power from the electric company goes off. Your lighting system will still work.
