Clear Answers to Frequently Asked Questions about Solar Panels

Questions about solar energy can be as varied as the many applications for which it is used. However, there are answers to some frequently asked questions about solar panels that provide basic knowledge for a solid foundation if you want learn more about and perhaps implement the use of solar panels. It just takes some solar education.

• What exactly is a solar panel and how does it work?

Solar panels have evolved over time. Technology continues to advance as time goes by and solar energy gains in popularity. The basic idea behind current solar panels is that a substance that readily loses an electron is contained in a substrate in order to provide a way to capture energy of the sun. Photons excite the atoms in the substance and cause a flow of electricity. The panel is designed to fully utilize this flow of energy and wires are present to capture the flow of electrons and direct them to other components of the system where electricity can be used or stored.

• If I set up a system, what equipment will I need?
• Some of the basic parts of a solar system include solar panels, a charge controller, a solar inverter and batteries for storage. Specific auxiliary components may be required, such as specific mounting hardware to best capture the sunlight available in your location.
• How much will a solar system cost and how many solar panels will I need to purchase?
• The answer to this question depends on the scope of your project. If you are setting up a system to run a garden fountain, you will need very little equipment. If you want to heat and cool your home and provide hot water, the answer depends on the size of your home and your energy consumption. The number of solar panels varies widely, although many people start small and continue to add to their system over time.
• If I use solar energy, can I still have my normal utility system as back up?

Check with your local utility company to find out what the requirements are for solar users. Not only do most people opt to have a solar system that remains tied to their local utility organization (grid-tied), but many solar users gain credits to their account when their utility meter 'spins backward' when they produce more solar energy than they can use.
