Impact Cards

The ‘Impact’ screen on the Tesla app provides you with cards that help measure the high-level impact and performance of your solar and Powerwall systems. Tap the timescale selector on the top right of the screen to change the time period for all impact cards.

Self-Powered

Tesla App Self-Powered Impact Card

The ‘Self-Powered’ card measures self-sufficiency, or how effectively solar and Powerwall power your home without the need to use energy from the grid. A ‘Self-Powered’ value of 100% indicates that your home is fully powered by stored solar rather than energy from the grid.

Energy Value

Solar and Energy Value impact cards

The 'Energy Value' cards estimates the value generated by your Solar and Powerwall system.

Energy Value is the estimate of the value of solar energy generated at your home, based on the price of energy from your tariff, which may vary throughout the day. This estimate accounts for your own solar consumption, and the exports to the grid for the value of the electricity on your tariff.

Energy Value also accounts for the additional value that your Powerwall generates by storing solar energy and lowering your consumption from the grid.

Solar Offset

Tesla App Solar Offset Impact Card

The ‘Solar Offset’ card contrasts your system’s solar generation against your home’s energy usage. Your ‘Solar Offset’ value can be higher than 100%, indicating that your system is producing more solar energy than your home is consuming — this typically occurs during the summer months. A low ‘Solar Offset’ value may indicate that you need to install more solar to fully cover your home’s energy usage. Viewing your ‘Solar Offset’ card by the ‘Year’ timescale can help you identify seasonal effects on solar production.

Time-of-Use

Tesla App Time-of-Use Impact Card

The ‘Time-of-Use’ card visualises your energy use while in Time-Based Control mode. Typically, while in Time-Based Control mode, you are reducing grid use during peak hours and shifting your grid use during off-peak hours. Tap the timescale selector on the top right of the screen to measure how well you’re meeting your Time-Based Control goals over time.

Backup History

Tesla App Backup History Impact Card

The ‘Backup History’ card displays events in which your Powerwall has powered your home during a grid outage. By default, this card only shows events during the selected timescale, but you can tap ‘View All Events’ to see backup events throughout the lifetime of your system.
