Bachelor thesis subject, a waste water treatment system using solar power, the air conditioner degrees Sunday to reduce power consumption, Eli is intended to study the efficiency of solar cells for electricity to be able to adjust the angle in degrees by using dc motors 12 Eli Sunday, Volt. With the light intensity sensor to make the solar cell Panel angle Eli Sunday. And energy that has been applied to waste water treatment system can be used in areas where there is no electricity available. In creating the artifacts to create solar cells can be adjusted to degrees Eli Sunday has itself without the use of solar panels to rotate and can be more than electricity generation solar cells.
