Overview of Solar PV Systems
Solar PV systems, more commonly known as solar panel systems, convert sunlight directly into electricity. They are composed of photovoltaic cells, which capture solar energy and transform it into electrical power. This on-demand conversion allows for effective energy usage in various applications.
In residential solar installations, three primary types of systems are commonly used: grid-tied, off-grid, and hybrid systems. Grid-tied systems are directly connected to the power grid, allowing excess energy to flow back to the grid and reduce electrical costs. Off-grid systems, on the other hand, are standalone units, suited for remote locations without grid access. Hybrid systems combine both configurations, offering flexibility and reliability by utilising solar panels along with a grid connection and storage solutions.
