Tesla Powerwall Without Solar
Powerwall is a system designed to save solar energy for emergency backup purposes, but there is also a way to store low-cost energy for your home without the need for solar.
Tesla’s Powerwall is a battery system that stores backup solar energy.
This is for protection in case there is a power grid outage and therefore no means to get electrical power in your home.
The question then is, what happens to Powerwall when solar power is not available?
Luckily, there are ways to use Powerwall to keep electricity running through your home without the use of solar, maintaining your energy independence.
Can You Use a Tesla Powerwall Without Solar?
Yes, the system is able to function using grid power, giving you access to backup power and more electrical freedom if there is a power outage in your area.
The Powerwall system is primarily designed for solar power, but it has some options for you if you are not interested in purchasing solar panels for your home.
The Powerwall system can instead store power from the grid power, giving you the same level of backup as with solar panels, but with less electrical freedom, since you will still be relying entirely on grid power for all your electricity needs.
Are Powerwalls Worth it Without Solar Panels?
The backup battery may be useful for your home, but it will not be cost-effective like it would be to get solar as well due to the tax credit and the lowered cost of electricity.
Although it is convenient to have the Powerwall in the event of a power outage, it may not be worth the money without also purchasing solar panels.
Grid power is significantly more expensive than solar power, making it a lot less cost effective to invest in Powerwall without the solar panel installation.
Additionally, without solar panels, you become ineligible for the 30% tax credit for solar power, which would bring down the cost of the installation significantly.
Having back up power is great for your home, and you still may want to invest in Powerwall for that reason, but it is not as cost effective as having solar panels installed in addition to the Powerwall.
Can I Buy a Tesla Battery Without Solar?
Yes, Tesla will install the Powerwall in your home without installing solar panels along with it.
Even without solar panels, you are still able to have Powerwall installed in your home, increasing your electrical independence.
The cost for the most recent version of the Powerwall battery by itself is $8500, which does not include the cost of installation, which would vary by the home.
Unlike with solar panels, there would be no means of making up this cost though electrical savings, but this may not be what you are after when purchasing a Powerwall battery system.
Getting a backup battery like the Tesla Powerwall would help to increase electrical independence and get backup power to your home when the power grid malfunctions.
How Long Will the Tesla Powerwall Last?
The backup energy can last more than a week if your home does not use too much electricity.
The unit itself is predicted to last around 10 years.
When your home has no power from the grid, the Tesla Powerwall can last a week or more as a backup energy source.
This may not be the case if your home has a lot of energy intensive appliances or equipment. In the case of a home with a lot of electrical needs, two Powerwalls may need to be installed to ensure the home is protected in an emergency.
Your energy professional will work with you to ensure you have the suitable amount of power to cover the needs of your home.
The lifespan of the Powerwall is approximately ten years.
This is how long Tesla’s warranty on them lasts, and though it is possible, it is unlikely they will be very functional beyond the ten year mark.
It is important to keep track of when you will need maintenance or replacements on your Powerwall in order to keep your home fully protected.
Final Thoughts
Getting Tesla Powerwall without getting solar panels installed is an option if you are looking for backup power without solar, but it is more cost-effective to also get solar power in addition to the Powerwall battery system.
