FAQs
Yes! By adding a Tesla solar battery backup system to your home, you can potentially save money on your power bill. Since the Tesla Powerwall charges with your solar panel system, having a solar battery backup can help you achieve greater savings.
The Tesla Powerwall is warrantied for 10 years with a guarantee that the battery will retain 70% of its capacity by year 10. Battery life is influenced by the number of times it is charged and discharged, which is known as a cycle. Therefore, when used for backup only and not regularly cycling, battery capacity is expected to be stronger than 70%.
Solar battery backup systems, like the Tesla Powerwall, can power large appliances for a short period of time, or small appliances for a long period of time. For example, without recharging from solar, one Powerwall can power 20 LED lights for two days or one refrigerator for six days.
Like solar panels, the number of Tesla Powerwall home batteries that you will need will depend on your home’s needs and usage. While one Tesla battery is sufficient to cover your basic energy needs, we generally recommend two or three battery back up systems to provide the best comfort and value.
Yes! While solar and batteries work best together, maximizing efficiency and savings, you can install a battery backup by itself. The installation of a standalone batteries can also qualify for the 30% federal tax credit.
Similar to a solar inverter, batteries are ideally located near the main electrical service panel. Our team will work with you to determine the best location. Indoor installation is always preferred, however they cannot be located in a living space or on a wall opposite a bedroom. In some cases, they can be installed outdoors, however an enclosure may be required.
Battery systems are designed to operate safely both indoors and outdoors, and do not pose any environmental threat during standard operation. We recommend that you exercise the same precautions that you would take with other electrical utility equipment.
When the power goes out in your home, the solar panels will stop working and automatically disconnect from the grid to maintain the safety of the utility workers attempting to restore power. Once the power is restored, your system will continue production after a few minutes. If it is important for you to maintain power during a blackout, we recommend adding one or more Tesla Powerwall home batteries to your system.
The battery inverter may make a faint humming noise, but should not be disruptive or even noticeable. Solar batteries are significantly quieter than other solutions, like generators.
One Powerwall can provide 13.5 kilowatt hours (kWh) per charge. The Powerwall 2 will discharge 5 kW continuously and the Powerwall 3 will discharge 11 kW until that 13.5 kWh is used.
When the sun is out, your home’s solar system collects that solar energy, which it then uses to directly power your home. If you don’t have immediate energy needs matching the amount of energy stored, that excess energy can be saved in your Tesla home battery for later use instead of sending it back to the power grid.
