All solar energy systems work on the same basic principles. Solar panels first convert solar energy or sunlight into DC power using what is known as the photovoltaic (PV) effect.
Grid-tie solar or Solar on grid systems are by far the most common and widely used by homes and businesses. These systems do not require batteries and use solar inverters or micro-inverters and are connected to the public electricity grid. Any excess solar energy you produce is exported to the electricity grid and you are usually paid a feed-in-tariff (FiT) or credit for the energy you export.
