Zero Energy Building

A building with zero net energy consumption over a year, achieved through a combination of energy efficiency and renewable energy generation, often including Tesla Solar Roofs.


The guarantee provided by Tesla covering the performance and quality of Solar Roof tiles and systems for a specified period.


A unit of energy representing one watt of power expended for one hour, used to measure electricity consumption.


A unit of power measuring the rate of energy conversion or transfer. In solar, it’s used to describe the output of panels or systems.


The measure of electric potential difference between two points, important in determining the electrical output of solar tiles and the overall performance of the system.

Uninterruptible Power Supply

A system that provides backup power during grid outages, often used in conjunction with Tesla Solar Roofs and Powerwall systems.

Utility-Scale Solar

Large solar power plants that generate electricity for sale to the grid. Tesla also engages in utility-scale energy storage solutions.

Tilt Angle

The angle at which solar panels or tiles are installed relative to the ground, which can affect their exposure to sunlight and overall efficiency.

Time-Based Control

A feature in Tesla’s energy management software that optimizes energy usage and battery charging based on time-of-use rates and energy demand.

Thin-Film Solar Cells

A type of solar cell made by depositing thin layers of photovoltaic material on a substrate, used for flexibility and integration in products like Tesla’s Solar Roof tiles.
