On-grid solar system
Solar panels convert solar energy into DC power. A solar inverter then converts the DC power into AC power which can be used to run home appliances. Depending on the type of system excess solar energy can also be fed into the electricity grid or stored in a battery system.
On-grid or grid-tie solar systems are by far the most common and widely used by homes and businesses. These systems do not need batteries and use common solar inverters and are connected to the public electricity grid. Any excess solar power that you generate is exported to the electricity grid and you usually get paid a feed-in-tariff (FiT) or credits for the energy you export.
