1. Resiliency from Power Outages
In a solar system without storage, your solar system is grid-tied, which allows your solar system to send any
excess energy back to the grid and receive a credit for this through net metering. Since the system is grid-
tied, in the event of a utility-wide power outage, your solar system will turn off automatically and stop
producing electricity. When you have solar storage capability you are able to pull electricity from your
batteries while the grid is down, which can be helpful for regular power outages as well as outages in the
event of an emergency.
2. Great for States Without Net Metering
Solar storage is a great option for states that don't have a net metering policy in place. For any electricity
that is not used in your home, that electricity gets sent to your home battery system, rather than going to the
grid and not receiving credit for that electricity. This can make installing solar more economical because the
homeowner is able to utilize their solar energy throughout the day, not just during the time that it is being
produced. This leads us to our next advantage.
3. Utilizing Solar Energy at Night
By having a storage option, homeowners are able to utilize the electricity their solar panels produce during
the day to power their homes and appliances at night. This allows homeowners to utilize their solar energy
at any time they'd like, not just when the sun is shining,
4. Potential for an Off_Grid System
Having solar batteries does not mean you are required to be off-grid. If you have solar + storage, you're
able to pull from your batteries at night when your solar system is not producing electricity. If your batteries
run out of power, your house is still tied to the grid and will receive power from the grid.
There is also an option with solar + storage to have an off-grid system, where your solar panels and
batteries provide 100% of the energy you need and you are not tied to the grid. Essentially, your energy
consumption is through a closed system, where the energy you produce is only being used in your home.
An off-grid solar system will require a significantly larger battery capacity than an on-grid solar system that
has a battery backup. This is because the batteries in an off-grid system will have to be large enough to
comfortably manage all of the electricity load for a home to account for the days that have peak electricity
usage
Installing Solar Storage
Many installers will have an option to include solar batteries when installing solar panels. However, if you
already have solar installed on your home, you can add a storage option to your solar setup after your solar
panels have been installed. If you're planning on installing a storage option after you've installed solar and
your electricity usage has increased, either from using more electricity or purchasing an electric vehicle, you
can also add more panels to your existing solar system. With the addition of batteries, homeowners can add
more panels to ensure that the solar system is able to cover their complete energy load year-round.
