Do solar panels have to be connected to the grid?

Uncertain, whether solar panels need to be connected to the grid depends on which power generation system you choose. There are grid-connected solar systems and off-grid power generation systems. You should choose according to your usage scenario conditions and needs

Grid-connected solar power generation system

The grid-connected power generation system must be connected to the grid, mainly including solar panels, grid-connected inverters, grid-connected cabinets, junction boxes, controllers, and grids. The stability of the grid is very important for the operation of the grid-connected system. When the grid is out of power, the photovoltaic power generation system will also stop working. Therefore, when choosing a grid-connected solar system, places with stable grids can be given priority. If you want to save electricity costs and have convenient power supply, a grid-connected solar power generation system is indeed a good choice

Off-grid solar power generation system

The off-grid solar power generation system is also called an independent solar power generation system. It is a power generation system that can operate independently without connecting to the grid. It mainly includes solar panels, off-grid inverters, batteries, junction boxes and other components. The direct current converted by solar panels through sunlight is converted into alternating current for household use through inverters, and the battery will also store electricity.
