Another option to consider when selling your car is word of mouth. Car collecting represents a relatively tight community, and the interconnections between its members can be very useful. When it comes time to sell your car, tell friends and other collectors with a shared interest that it’s for sale. Part of the magic of the collec- tor car hobby is that if you tell fellow enthusiasts you’re selling your car, they’ll tell their friends who share the same interests and so on. It’s not unusual for a car to sell on word of mouth alone when the informa- tion is. | Snarer ur Own Background Not only is the sun a source of heat and light it s a source of electricity too Solar cells also called photovoltaic cells are used to convert sunlight to electricity. Solar cells are used to provide electricity all kinds of equipment from calculators and watches to roadside emergency phones and recreational vehicles. Solar panels are becoming common on many homes. Solar cells are most commonly made from silicon the same material used to make computer chips. Silicon is one of the Earth s most common elements and is a major component of sand and many kinds of rocks. A solar cell is built like a sandwich with two layers of silicon separated by a thin layer of insulating material. All three layers work together to convert sunlight into electricity. When sunlight falls onto the solar cell it produces a small electric charge. Like a battery the charge is positive on one side of the cell and negative on the other. A wire connects the two sides of the cell allowing electricity to flow. This flow or current of electricity can be used to power a small light bulb turn an electric motor or recharge a battery. . renewab e Energy Page 1 of 1 Solar cells are often used in locations where there isn t any electricity and where electricity is needed in small amounts. In such cases solar cells are usually connected to batteries allowing electricity to be stored for use during times when the sun isn t shining. A single solar cell is able to produce only a small amount of electricity. But solar cells can be connected together on a multi-cell panel to produce larger amounts of electricity. As with batteries the more cells that are connected to one another the greater the current of electricity that can be Solar panels can produce enough electricity to power satellites recreational vehicles and equipment for other applications where electricity is used in large amounts. For this project you will be using the electricity from solar .
