 * 1) The energy source that powers a solar panel is free.
 * 2) Photovoltaic systems convert light into electricity.
 * 3) The transfer modules that capture the sunlight are called panels.
 * 4) The solar panels produce Direct Current energy.
 * 5) The device in the panels convert the Direct Current in to Alternating Currents.
 * 6) The device is called an inverter.
 * 7) Alternating Currents is the form of energy used in the United States.
 * 8) There are three types of solar electric systems.
 * 9) The three systems are grid connected, off-grid, and grid connected with backup.
 * 10) The grid connected system uses solar panels and then balances the rest of the houses electrical need with the grid.
 * 11) The off-grid system is "true energy independence'.
 * 12) Grid connected with back up is connected with the grid but if there is a power outage, the solar panel's batteries kick in.
 * 13) Grid connected systems are the cheapest.
 * 14) Most panels in suburbs and cities are mounted on roofs.
 * 15) The tilt of the panels should correspond to the latitude that they're being set at.
