A grid-connected solar system, also known as an on-grid or grid-tied system, is a type of solar power setup that is directly connected to the utility grid. Unlike off-grid systems that rely solely on solar energy stored in batteries, grid-connected systems utilize the utility grid as a backup power source, ensuring continuous electricity supply even when solar energy production is insufficient. These systems consist of solar panels, inverters, and electrical wiring that connect the solar array to the existing grid infrastructure. When the sun is shining, the solar panels generate electricity, which is converted from direct current (DC) to alternating current (AC) by the inverter for use in homes or businesses. Any excess electricity generated can be fed back into the grid, often through net metering arrangements, allowing users to earn credits or even receive payments from the utility company. Grid-connected solar systems offer a reliable and cost-effective way to generate clean electricity while maintaining connectivity to the existing utility infrastructure, contributing to a more sustainable energy future.
