Sources of Energy You have different sources of electricity generation on your tables. Each set shows the electrical generation process Sort the cards at your table in the correct order. You may not need to use all the cards. Once you have it, line up the cards along the wall in order.

Where Does Arizona Get Electricity? There are 12 sections. Think in terms of fractions or percentages. Try to think of all the sources Arizona uses. Assign a value to each.

Where Does Arizona Get Electricity? Create a Pie Chart Use different colors for different sources. For example, solar might be green and hydro power might be blue. Use the template as a guide. Think of all the ways electricity is generated. Think about what percentage or fraction each source is of all the electricity Arizona generates.

Electromotive Force What similarities do you see? Is there anything different in the process? Which ones would you consider “efficient”? Which ones would you consider “green”? Which is the cheapest? Which is the most expensive?

Moving Electrons Connect the hand-crank generator to the test bed. Set the switch to “Incan” for incandescent bulbs. Turn the generator and see if you can light all the lights. Now set the switch to LED and turn the generator again. What happened? Discuss at your table.

Passive Solar These homes in Montana and California with a passive solar design heats the home in the winter and cools the home in the winter.

Daylighting Langston High School in Arlington, VA and Caywood Elementary in Kentucky use daylighting to keep energy costs down.

Active solar heating is much like passive solar heating except it takes the power of the sun and amplifies it. The people living in this house enjoy heated water using a solar thermal system. Flat plate solar collectors are usually large flat boxes with one or more glass covers. Inside the boxes are dark colored metal plates that absorb heat. Air or liquid, such as water, flows through the tubes and is warmed by heat stored in the plates. These systems are particularly useful for providing hot water to households. Active Solar Heating

Concentrating Solar Power A clean, large-scale solar thermal technology known as concentrating solar power is used in special power plants (Concentrating Solar Power or CSP plants) that use different kinds of mirror configurations to convert the sun's energy into high-temperature heat. The heat energy is then used to generate electricity in a steam generator.

Power Tower World’s largest solar power tower in Seville, Spain. Solar power tower consists of a large field of sun tracking mirrors, called heliostats, which focus solar energy on a receiver atop of a centrally located tower. The enormous amount of energy, coming out of the suns rays, concentrated at one point (the tower in the middle) produces temperatures of approx. 550 C TO 1500 C. The gained thermal energy can be used for heating water or molten salt, which saves the energy for later use. Heated water gets to steam, which is used to move the turbine generator. This way thermal energy is converted into electricity.

Photovoltaic systems convert sunlight directly into electricity, and are potentially one of the most useful of the renewable energy technologies. Also known as solar cells, PV systems are already an important part of our lives. The simplest systems power many of the small calculators and wrist watches we use everyday. Photovoltaics

PV Cell The photovoltaic cell is the basic building block of a PV system. Individual cells can vary in sizes from about 1cm to about 10 cm across. Most cells are made with silicon today. Silicon must be purified– this is one of the biggest expenses in the production of solar cells.

PV Array Components PV Cells Modules Arrays One PV cell only produces 1 or 2 watts of electricity, which isn't enough power for most applications. To Increase power groups of solar cells are electrically connected and packaged into packaged weather-tight modules and arrays to provide useful output voltages and currents to provide a specific power output. A PV System typically consists of 3 basic components. PV cells - Electricity is generated by PV cells, the smallest unit of a PV system, Modules - PV cells are wired together to form modules which are usually a sealed, or encapsulated, unit of convenient size for handling. Arrays – Groups of panels make up an array.

PV System Components Solar PV System
Solar cells produce direct current (DC), therefore they are only used for DC equipments. If alternating current (AC) is needed for AC equipments or backup energy is needed, solar photovoltaic systems require other components in addition to solar modules. These components are specially designed to integrate into solar PV system, that is to say they are renewable energy products or energy conservation products and one or more of components may be included depending on the type of application. The components of a solar photovoltaic system are: Solar Module is the essential component of any solar PV system that converts sunlight directly into DC electricity. 2. Solar Charge Controller regulates voltage and current from solar arrays, charges the battery, prevents battery from overcharging and also performs controlled over discharges. 3.Battery stores current electricity that produces from solar arrays for using when sunlight is not visible, nighttime or other purposes. 4. Inverter is a critical component of any solar PV system that converts DC power output of solar arrays into AC for AC appliances. 5. Lightning protection prevents electrical equipments from damages caused by lightning or induction of high voltage surge. It is required for the large size and critical solar PV systems, which include the efficient grounding.
