Solar panels are just the first step in solar energy production. Capturing the photons from the sun, the individual cells on a solar panel release a flow of electrons, otherwise known as dc current. This initial raw energy will eventually make it into our homes or back to the grid – clean, green and renewable.
For maximum electricity production, solar panels must be mounted in an area with little to no shade and in a south facing orientation (in the northern hemisphere). As solar panels can only produce electricity during the day when there is sun exposure, back-up systems such as generators (for remote areas) or having access to the grid (when possible) must be used during the night or when there is limited sun. While typically found on rooftops, panels can also be mounted up on poles, high and out of the way of any obstructions, or even be mounted on a tracking system that follows the sun to produce even more energy.
The use of renewable energies benefits the entire planet and its inhabitants because it reduces fuel consumption and our carbon footprint. With the installation of solar energy systems, savings and the resulting reduction of environmental impact is significant. Studies indicate that more than 8,000 tons of carbon dioxide would no longer be issued for every 5,000 homes that had this technology.
