Questions: 1. The ways solar panels work is from the energy generated from photons hitting the surface a solar panel. This makes the electrons pushed out of their orbits and released, and electric fields in the solar cells pull the electrons in a directional current. The electrons hit the metal in the solar cell which then generates electricity. 2. 3 types of renewable sources are hydropower, geo thermal, and wind power. Hydropower is used in rivers and its natural flow. Dams are built across the river and have turbines inside them. When the water flows the turbine spins which turns an alternator which

Unformatted text preview: generates electricity. Geothermal power uses a turbine, hot water and cold water to generate steam. This steam also turns a turbine which is attached to a generator to generate electricity. Wind power is the most common using windmills that spin. The spinning occurs from the natural wind blowing which turns the generator making electricity. 3. The role of the inverter in the cell is to change the voltage to either 12v DC, or 120v Ac depending on where the electricity is going....
