Tesla’s mission is to accelerate the world’s transition to a sustainable energy future by creating products that are so compelling, there is no alternative. Solar energy has always been part of our master plan, and we recognized the need for a roof that is simultaneously affordable, durable, beautiful and integrated with battery storage.
Solar Roof complements a home’s architecture while turning sunlight into electricity. With an integrated Powerwall, energy collected during the day is stored and made available any time, effectively turning a home into a personal utility. Solar energy can be generated, stored and used day and night, providing uninterrupted power even if the grid goes down.
Solar Roof is more affordable than conventional roofs because in most cases, it ultimately pays for itself by reducing or eliminating a home’s electricity bill. Consumer Reports estimates that a Solar Roof for an average size U.S. home would need to cost less than $24.50 per square foot to be cost competitive with a regular roof. The cost of Solar Roof is less. The typical homeowner can expect to pay $21.85 per square foot for Solar Roof,1 and benefit from a beautiful new roof that also increases the value of their home.
Solar Roof uses two types of tiles—solar and non-solar. Looking at the roof from street level, the tiles look the same. Customers can select how many solar tiles they need based on their home’s electricity consumption. For example, households that charge an electric vehicle every day may want more solar tiles on their roof.
In doing our own research on the roofing industry, it became clear that roofing costs vary widely, and that buying a roof is often a worse experience than buying a car through a dealership. Initial contracts tend to be overly optimistic, and later customers face hidden costs that were never mentioned up front.
At Tesla, we believe in transparency and putting the customer in control. That’s why we created a Solar Roof calculator that lets homeowners estimate the upfront price of Solar Roof, as well as the value of the energy it can generate for their home. The calculator is based on factors like roof size, the average local price of electricity, and how much sunlight a neighborhood receives throughout the year.
As shown in the graph below, the cost of our non-solar tiles is comparable to regular roofing tiles.2Although the cost of our solar tiles is more expensive up front, it can be more than offset by the value of energy the tiles produce.3 In many cases, the reduction in a home’s electricity bill over time will be greater than the cost of the roof.
