You will observe that the colors change as the copper starts to oxidize, and gently transform to black. Let the copper stay on the burner for about 40 minutes or up to the time that a thick coat of oxidized black material turns up. Turn the heat off on the burner, then let the copper cool in the air. The solar power delivered to utility companies and used by people for various electrical applications is used all over the globe. Solar panels can be used to heat and power different electrical appliances in the house. Solar panels can also be used to convert sunlight into electricity to power heating systems, lights and air conditioning systems. The flow of solar energy electricity is measured via a utility meter that spins forward and backward. The meter will move backward if more energy is produced than needed and the meter will move forward when extra power is required from the utility company. The two are only even when additional energy is paid for from the utility company. You can get a device rated at 12 volts or higher for only $100 at a marine supply store or RV store. Next, purchase a battery. Experts recommend that you get rechargeable batteries from available green companies. Get any size of deep cycle 12 volt lead/acid or gel battery. You will need the deep cycle battery for nonstop use. As soon as the heat is captured, people can put the energy into good use. Basic Heat Principles Heat is described as a form of energy that is related to the movement of molecules. Once the electromagnetic waves that emanate from the sun hit an object, these will excite the molecules of the object, triggering movement. Majority of solar cars were made with the objective of solar car races. A few exceptions include solar-powered cars and utility vehicles. Solar cars are usually fitted with the gauges similar to conventional cars. The driver has to watch the gauges closely to see potential problems and keep the car running very smoothly.
