A Tesla solar roof will cost you about $21.85 per square foot. This is really pretty remarkable since it’s not not terribly more expensive than a premium traditional roof, and it will save you substantially on your energy use over time.
Keep in mind of course, that this number is an average, and there are many factors that will affect the actual cost. Depending on the climate in your location, the orientation of your roof, and shading, the number of “active” versus “passive” tiles will vary. Obviously, these factors will also assure that your energy savings vary as well. Still, Tesla beats Consumer Reports’ initial cost estimation by seven percent.
Tesla provides on online calculator to help you get a better grasp on your individualized costs and savings. It requires your address, square footage, and number of stories. It factors in the size of your roof and energy costs in your area, to come up with a figure. The calculator leaves out shading, as well as roof orientation.
EnergySage will hook you up with a local company that can handle your solar roof needs, whereas Tesla’s calculator deals with only Tesla roofs. The EnergySage calculator gives you a detailed report including information like of the amount of time it will take you to reap a full return on your investment, and estimated savings if you lease a system. Tesla’s calculator just provides bottom line pricing and return on investment.
Tesla shows a net ROI of $3900 over 30 years, but remember that the Tesla roof is intended for new constructions or houses that are being re-shingled, and the Tesla estimate includes the cost of a Powerwall battery, which is not included in the EnergySage report.
The takeaway from this is that – much like Tesla’s vehicles – you will likely pay more for a Tesla solar roof than you would for the competition. Tesla products tend to be more extravagant and stylish (bells and whistles … “whiz bang” as Elon Musk puts it). You will be hard-pressed to find a solar roof with the look and style of the Tesla product. Like Model S, Tesla Solar Roof Is Expensive, But Stylish
