This is the original model. This model is all full-amount online mode, whether it is the photovoltaic company renting the roof mode or the owner self-investment mode. All the electricity generated by photovoltaic solar panels is sold to the power grid.

The second point is that the electricity generated by household photovoltaics installed in the whole village is self-generated and self-used.

The third point is that it needs to be installed Install 50% of the energy storage equipment, that is, energy storage batteries are needed.

A photovoltaic company installed 4 megawatts of photovoltaic solar panels in a small town. The solar company needs to install 2 megawatts of energy storage equipment, and the photovoltaic electricity generated by the solar company needs to handle it by itself. The unused electricity is stored through the storage equipment. When the storage capacity is full, it is traded through the electricity market.

Then there is another point. No matter how many household photovoltaics you install in the village, it can only be counted as one household. All the above-mentioned mode changes are called household photovoltaics being industrialized and commercialized.
