The new path of the wire is twice as long as last year's wire. It was made longer because the client requested that the wire run around the edge of the roof before running down to the school's battery station. As a result the gauge of wire was increased to 10 gauge to increase safety and reduce resistance in the electrical current being transmitted.
The electric energy the solar panel and turbine generator is direct current. In this system a 1-amp diode was placed on the positive line from the solar panel and a 6-amp diode was placed on the positive line from the turbine generator. Additionally a 2-amp fuse was placed on the positive line from the turbine to prevent energy spikes from the wind turbine. A fuse was omitted on the positive line from the solar panel because the maximum power output (10W) was not considered a hazard to the system.
The combined electrical power is then transmitted to the relay in the battery station that takes any excess energy (24+ volts) to a shunt resistor to prevent energy surges from damaging the system. A shunt resistor is a coil of wire that turns electric energy into heat energy, expending the excess energy diverted by the relay.
