Why do solar cells only produce direct current? When the sun shines on the surface of the solar cell, it will stimulate the flow of electrons, thus generating an electric current. Now, these electrons only flow in one direction. One-way electron flow generates direct current or direct current. Therefore, solar cells can only produce direct current, not alternating current. Otherwise, the inverter will not be needed in this case. Why do we use AC instead of DC in our home? There are two main reasons why we use AC instead of DC at home. Therefore, we cannot directly use the DC output of solar cells and solar panels. They are as follows: 1. Most of our household outlets and appliances use alternating current. 2. Power from the public grid is also in the form of alternating current. Household sockets and appliances use AC instead of DC. DC is not something that we can directly use to power most household equipment. This is the main reason why we need to use inverters to benefit from solar energy. In the daytime, solar energy can supply power for our family with the help of inverters. Inverters can convert DC voltage and electric energy into AC power, enabling us to use household appliances. In the case of solar grid-connected power generation system, when the solar energy exceeds the energy demand of our family, the surplus power will be output to the grid. The distribution network uses AC instead of DC. Unless you want to leave the grid, you need to get electricity from the public grid to use household appliances. The way they transmit electricity from power plants is through transmission and distribution lines. These lines use high voltage and low current AC power to minimize electrical losses. Therefore, your solar panel system needs to be adjusted according to the power demand of your home, that is, the form of alternating current. When you connect the grid-connected solar system, you also need to synchronize its output power to the grid. Now, this is another reason why solar cells and solar panels need inverters.
