To use solar panels during a power outage, homeowners need to have a battery backup system in place. This backup system allows the solar panels to continue generating electricity even when the grid is down. The battery backup system stores the excess energy generated by the solar panels during the day, which can then be used to power appliances and devices when needed.
Not all solar panel systems are designed to work during power outages. Homeowners who are interested in using solar panels as a backup power source should look for systems that are specifically designed for this purpose. These systems typically include a battery backup and other features that allow them to operate independently of the grid.
Types of Solar Panel Systems for Power Outages
During a power outage, a solar panel system can be a reliable source of energy. There are various types of solar panel systems that can be used during power outages.
Grid-Tied Solar System
A grid-tied solar system is connected to the electrical grid, and the excess energy produced by the solar panels is sent back to the grid.
During a power outage, the grid-tied solar system will not provide electricity unless it has a battery backup or a generator.
Off-Grid Solar System
An off-grid solar system operates independently of the electrical grid. It typically includes a battery storage system, which stores excess energy produced by the solar panels for use during power outages.
Off-grid solar systems require careful planning and sizing of the solar panels and battery storage system to ensure that they can provide enough power to meet the needs of the home.
Hybrid Solar System
A hybrid solar system is a combination of a grid-tied solar system and an off-grid solar system. It can operate independently of the electrical grid and provide power during a power outage.

Understanding Solar Power and Outages
The Difference Between Off-Grid and Grid-Tied Solar
Solar panels can be used in two ways: off-grid and grid-tied:
- Off-Grid: Off-grid solar systems are independent power systems that do not rely on the electrical grid. They store excess energy in batteries for use when the sun is not shining.
- Grid-Tied: On the other hand, a grid-tied solar system is connected to the electrical grid. The excess energy produced by the solar panels is fed back into the grid, and the homeowner receives credits for the energy produced.
What Happens to Solar Energy if My Power Goes Out?
During a power outage, a grid-tied solar system will automatically shut down to prevent any potential safety hazards to utility workers trying to fix the power lines. This means that even if you have solar panels, you will still be without power during an outage. However, homeowners with off-grid solar systems will still have access to power during an outage.
The Role of Inverters
Inverters convert the direct current (DC) produced by the solar panels into alternating current (AC) that can be used to power homes and businesses.
During power outages, inverters are designed to shut down to prevent any back feed into the grid. However, some inverters have a feature called “islanding” that allows the solar system to continue providing power to the home during an outage, but this feature is not available in all inverters.
Solar Battery Systems
Solar Batteries Keeps Your Electricity Going
During power outages, a solar battery system can keep your electricity running.
A solar battery stores excess energy generated by your solar panels during the day, so you can use it at night or during a blackout. With a solar battery system, you can power your home with clean energy even when the grid is down.
Battery-Backed Solar Systems
A battery-backed solar system is designed to keep your home powered during a blackout. These systems are connected to the grid, but also have a battery backup to provide power when the grid goes down.
The battery backup can provide power for a few hours or even days, depending on the size of the battery and the amount of energy your home uses.
How Solar Works During a Blackout
When the power grid goes down, your solar panels will continue to generate power as long as the sun is shining. However, without a battery backup, you won’t be able to use that power.
This is because your solar panels are connected to the grid, and when the grid goes down, your solar panels shut off to protect utility workers from electrocution.
Battery Storage During a Blackout
With a battery backup, your solar panels can continue to generate power even when the grid is down. The excess energy is stored in the battery, which can then be used to power your home. During a blackout, your home will draw power from the battery instead of the grid.
