3. INTRODUCTION What is Solar Energy? Solar energy is energy(light or heat) that comes from the sun. Solar energy examples What makes your car or hot when it is parked in the sun ? What makes your solar calculator work ? What makes plant grow ? FORMS OF SOLAR ENERGY There are two basic categories of Solar Energy: 1) Solar Thermal- Using the sun’s energy to heatthings like your house, water, food, etc. Solar Electric- Turning light from the sun directlyinto electricity, using solar panels.

4. What is a Solar Panel? Solar Panels are commonly called Photovoltaic Panels (PVPanels) Photo means light and voltaic means electricity. Photovoltaic panels are made from Silicon which is the samematerial that makes up sand. When the sunlight hits the PV panel, it moves around tinyparticles of silicon called electron Sunlight’s Affect on the Earth The earth rotates on its axis which creates the change from day tonight. The earth’s axis is at an angle of 23.5 degrees, this tilt createsseasons.

5. Solar Collector Position So the optimal tilt angle for solar panel for a certain month/season is based on: Season The location (North/South) on the planet Solar Thermal Design PV panel will collect the solar energyand convert it into electricity to be stored within the battery The battery will operate the pumpdevice which will force liquid throughthe system

6. Solar Air Collector Design:- DESIGN POSITIVES DESIGN NEGATIVES Extremely efficient! Only two PV panels required Design will not be able to run on cloudy days. Design will only run for an average of three hours per day

7. Conclusion An important benefit of solar energy is the secure and independent energy supply in rural and remote areas that can advance the development process more rapidly at lower cost than comparable efforts based on non- renewable conventional energy sources.
