If your solar energy system produces more energy than your family needs at a given time. Electrical energy can often be utilized in different ways. In a grid-connected system, the electricity can flow into the city’s power grid company. In an off-grid system, the electricity can be stored in solar batteries for later use.
Where the excess electrical energy goes:
1. stored into batteries
In an off-grid or Hybrid solar system, for households that have a home solar and battery storage system, excess solar power can be stored in the batteries connected to that system for charging the batteries. The solar panels convert the solar energy into DC power, which is converted to AC power by an inverter for the home’s use, and the remainder is charged to the batteries by a solar charger. When there is a shortfall in the household’s power needs, the battery will supply the required power to make up the difference.
2. Flow back to the city grid company
In grid-connected and hybrid systems, the city grid company keeps track of how much energy you consume from the grid and how much you export to the grid based on net metering, which measures how much excess energy your solar system sends to the city grid company and how much electricity you receive from the city grid company. From this, you are likely to receive credit for the energy you export, which provides you with additional power, which offsets the cost of the power you consume from the grid company.
During the day solar panels provide plenty of energy, far more than what we use in our homes. And at night, on cloudy days or when the sun isn’t shining enough and may not be able to provide us with the power we need, you can get power from the city utility company as a way to achieve a balance of power.
As a result, not only can we meet our energy needs, but we can also save some money on our electricity costs. However, not all markets offer net metering, and for areas with limited net metering, energy delivered to City Utilities and net metering credits may be limited.
Can excess energy produced by solar energy damage a solar system?
The answer is no. In a grid-connected system, all excess energy goes to the grid company, so it will not damage the solar battery system. In an off-grid system, when the batteries are full and the household electricity requirements are met, there is still power left over, at which point the PV panels will be lowered by the inverter to reduce the power, and thus the power supply, so that the excess power will not damage the panels.
To summarize
Even though your solar system produces far more energy than your home uses, there is no need to worry. This excess energy is often utilized efficiently in different ways, thus saving you money on electricity costs.
