Sunroom photovoltaic panels connected to the grid
In a grid connected PV system, also known as a “grid-tied”, or “on-grid” solar system, the PV solar panels or array are electrically connected or “tied” to the local mains electricity grid which feeds electrical energy back into the grid. . Here are design tips for methods of PV system utility interconnection. Load-Side Connection Dominates Residential Installations: The 120% rule limits total. . To connect solar panels to the grid, you need to install a bi-directional meter on your home. This allows energy produced by your solar panels to be fed into the grid when you're not using it, and for you to draw energy back from the grid when you need it. Each photovoltaic panel has a power rating of 550W.
