  1. Solar Photovoltaic Demonstration

  2. History of the Solar Panel The solar panel was developed in 1839 by Charles Fritts, with very high expectations. With the overpopulation of the world the energy that was being both used and produced exceeded the amount the earth could sustain. The greenhouse gases that were a result of this production of energy and created a major problem within the earth’s atmosphere. The solar panel was then developed to take the energy produced by the sun and transfer it into usable energy within the household or office. When the sun’s rays hit the panel, its light gives electrons energy that are embedded in the panels surface. These electrons begin to move and bounce off each other rapidly which in return creates the energy needed to run the electronics used in everyday life.

  3. Objective The objective of our project was to determine the amount of energy that one solar panel produces on a daily basis and interpret this data to estimate the number and size of solar panels an average family would need to run their house.

  4. Materials Throughout our project we used the following materials : -One 40W Solar Panel -Sunforce 7A Charge Controller -UB12220 12V Battery -PowerBright 200W Inverter -Multi-meter or datalogger capable of measuring current -Ladder -Black Tape -two stools

  5. Procedure • This was the process we used to create our project • We connected the solar panel to the Sunforce 7A controller • We then connected the high current sensor into the circuit to measure the amount • of energy produced by the panel. • We connected the positive and negative wires of the Sunforce 7A controller to • the battery through the cables of the 200W power converter.

  6. Results Our project resulted in the solar panel fully charging the battery. The time it took for the battery to charge varied on the day. Some days the solar panel would create no power because the sun was covered throughout the entire day, on other days the battery would become charged within that day while in direct sunlight. The measurement on current however failed to produce any results because for some unknown reason the sensor would not log any data. In the end we conclude that one solar panel could not sustain an entire household and we would like more time to run some more tests to determine the size and number of solar panels needed to sustain a family.
