Your Top Solar + Tesla Powerwall Questions Answered.
Why Would I Want Grid-Tied Solar + Tesla Powerwall?
Grid-tied solar electric systems do not require batteries to work. Thanks to the net metering policy, you can get the full value of all of the electricity your system produces without relying on batteries. However, it is important to understand that a grid-tied solar electric system will not provide backup power during a power outage. If you would like to leverage your investment in a solar electric system to have a rechargeable backup source of power during a power outage, you need to add a battery backup system like the Tesla Powerwall.
What Is The Tesla Powerwall?
The Tesla Powerwall is a 13.5 kWh rechargeable lithium-ion battery primarily for home storage and commonly paired with solar panels. Like any other battery storage option, a Tesla Powerwall captures and holds the energy to provide backup power in the event of a power outage and can help you achieve a more independent energy lifestyle and peace of mind.
What Are The Benefits Of The Tesla Powerwall?
Its capacity to support larger loads makes the Telsa Powerwall different from other battery storage options currently on the market. That means you have the freedom to power up more of what you need. It is designed for self-consumption, Time-of-Use control, and short-term backup power. The Telsa Powerwall has a user-friendly customer interface and has an excellent dollar per kWh value.
Solar Day and Night
Most homes use a fraction of the solar energy they produce. Instead of sending it back to the grid, Powerwall stores it for later use.
Backup your home
Powerwall is a backup system that keeps your lights, Wi-Fi, and refrigerator running during a power outage.
Energy Independence
You will not even notice when the backup mode is on, as Powerwall will seamlessly switch to this mode for you.
How Does A Tesla Powerwall Battery Work?
The Tesla Powerwall connects to the electrical system in your home and has a stored energy bank that can power your loads. On its own, a Powerwall will automatically keep your home powered when the power goes out When combined with a solar array, the Powerwall can be recharged during an extended power outage. It can also be used to “Self-Consumption” more energy, storing power from your solar array during the day and then using battery power at night without drawing any energy from the utility.
Can I Install A Tesla Powerwall If I Already Have Solar?
Yes, in most circumstances, you can. A Powerwall can retrofit most existing home solar systems. In this case, a homeowner usually has a few brands that make up their solar electric system. Your current inverter and layout will determine the size and design of a battery for existing equipment. Contact us, and we will be able to tell you if your current solar configuration supports adding a Powerwall.
Can I Install A Powerwall If I Don’t Have Solar?
Though a Tesla Powerwall installed without solar can charge from the grid, there is not as much benefit of having battery storage if it’s not connected to a solar electric system in Maine. Unlike areas with high variation in on-peak and off-peak rates (think California), it isn’t as financially rewarding here.
Without solar, the Powerwall has no way to recharge during an extended outage. So a Powerwall may help with short, temporary power outages, but once the battery is depleted, you must wait until utility power is restored. A Powerwall cannot be configured to charge from a generator source.
The best solution is to include a battery backup with a solar electric system. This does add a cost to the system’s price, but batteries are eligible for the 30% Federal Solar Investment Tax Credit.
Who Can Install Tesla Powerwalls?
A company must be a Certified Tesla Powerwall Installer to purchase and install Powerwalls. Companies must adhere to strict quality, permitting, and inspection requirements to become Certified Installers. Maine Solar Solutions was one of the first Tesla Powerwall Certified Installers in Maine. We are thrilled to be the first *Tesla Solar Panel installer in the state, providing another panel option for our customers.
Will Tesla Be Launching A Powerwall 3? Should I Wait?
From what we know, there are no plans to launch a new Powerwall anytime soon. However, batteries are in the early adoption phase, and waiting is okay. That is one of the major reasons we future-proof our systems so you can install batteries later.
