Electrical system interconnected to the grid

Let’s start using the simplest home solar power system connection, which is grid tie solar electric power system. The grid that is being talked about is the electrical grid that your house is on. Each and every city has built a power grid so that the power company can provide power to your residence.

If you’re on the power grid, you’ll spend money on electricity as soon as you open an account and turn on the lights. With the grid-tied system, any solar-powered electricity you generate from your home solar system is piped directly into your home’s electrical grid. The electrical power produced in the solar electrical panel array is then passed through a DC disconnect panel. This device interrupts the power flow of the matrix.

After that, an inverter changes the direct current from the solar electric panel into alternating current for the outlets in your home. The inverter is connected to your main panel. When you use electricity from solar power, you may find your meter running in reverse while you pay the price of your electricity bills. Tell your utility company and hire a qualified electrician to do the wiring work.

Electric system interconnected to the grid with battery backup

The difference between this method and the first is that you can literally store excess electricity for a rainy day. If the sun is bright and strong like in the summer season, you can use a grid-connected electricity system that is equipped with a battery.

Solar electricity still flows from the photovoltaic (PV) array to your entire system, but it is sent to a battery landfill. A load control panel monitors the movement of electrical power. The electricity then flows to the inverter and the rest of the system just like the grid-tied system. Only the surplus is kept inside the battery.

Off Grid Solar Power System

This method will work great for those who are not installed on a power grid. They sit too far from cities and towns to be covered. The solar electric system is your only source of electricity.

This particular type of home solar power systems flows similarly to the grid-tied system with battery backup. A battery stores electricity for days when the sunlight is not strong. You still need electricity all those days. From the breaker panel, electricity goes directly to your sockets rather than to the meter since you won’t be connected to an electrical grid. At the same time, you will see a backup power generator with most of these systems.

Each of these home solar power systems is priced differently. The purchase price increases with additional features. Choose a system that meets your requirements to save the most money possible on electricity for your home.
