What are the Common Grid Connection Modes of 10 kw on Grid Solar System

Distributed photovoltaic power station refers to the power generation system with small installed capacity and arranged near the user. It is generally connected to the power grid of 10 kV or lower voltage level. The small-scale household rooftop photovoltaic power stations we usually see are distributed photovoltaic power stations.

At present, the grid company allows the owners of photovoltaic power stations to adopt three grid-connected settlement methods for the application of distributed photovoltaic power stations, namely, self-use, self-use, surplus power grid, and complete grid connection.

Spontaneous self-use means that the power generated by distributed photovoltaic power stations is used by the power generation enterprises themselves. This mode is applicable to production and manufacturing enterprises that need long-term and durable electricity. The demand for electricity is large, and can completely or largely absorb the electricity generated by photovoltaic power stations. In order to avoid reverse power transmission, it is necessary to configure anti-reverse current device for alarm, and the inverter will adjust the capacity according to the received signal.

The advantage of the self-use grid-connection mode is that it is relatively independent and has very obvious economic benefits for enterprises with large demand for electricity. This grid connection mode can also be selected for areas where power transmission is limited or photovoltaic power generation is not supported.

Spontaneous self-use and surplus power grid access means that enterprises only use a part of the power generated by distributed photovoltaic power stations and sell the remaining power to grid companies. This mode is applicable to enterprises with small power demand in production. For such enterprises, spontaneous self-use and surplus electricity are the most ideal mode of grid connection. After all, while the enterprises enjoy clean and low-price green electricity, the rest is sold to the power grid company to obtain corresponding income, killing two birds with one stone.

Full grid connection means that the power generated by distributed photovoltaic power stations is directly connected to the grid company, and the power used by enterprises is obtained from the grid. This grid-connected mode is the most mainstream and simplest in the past ten years. After all, the subsidies in various places are relatively large. For enterprises, while enjoying the original electricity price, the extra electricity price benefits of the power station are also very considerable.

In the process of application of the grid-connected mode of distributed photovoltaic power stations, enterprises need to analyze specific problems and choose the most suitable mode according to the installed scale of photovoltaic power stations, power generation, their own power consumption, power cycle, local policies, local electricity prices and other relevant factors.
