At present, there are usually three "grid-connected modes" of solar photovoltaic power plants in the market: spontaneous self-use surplus electricity grid-connected mode, full grid-connected mode and full self-use mode.

First of all, if you choose one of these three grid-connected modes, you need to choose it according to your actual situation: for example, like ordinary families, most people choose the mode of spontaneous self-use surplus electricity to access the Internet, which is also the mode with the highest proportion of distributed photovoltaic power plants.

The advantage of this model is that the electricity generated by photovoltaic power plants is used for household power supply first, and then the excess electricity is automatically merged into the power grid, which can avoid waste and make money. This mode is more suitable for ordinary home users and economical, because there is no need to spend extra money on batteries to store electricity.
