First and foremost on that list is protecting the home from rain. Installing a Solar Roof also means the entire systems is installed to maximize the collective goals of a roofing system. Our two Tesla Powerwalls after installation. On the other hand, it’s likely the third Powerwall would not see much use in the winter months when our system generates less power. A third Powerwall would store more of our locally generated power and give us a larger margin for backup power. They fill up a bit earlier in the sunny summer months and a bit later in the foggy winter months, but it’s clear we could have made use of a third Powerwall. When the Powerwalls are set to maximize self-consumption, we tend to fill them up right around noon. It feels strange to not be maximizing our consumption of the power generated by our solar system, but using the time of use mode results in a more stable grid and ultimately, lower emissions for everyone. On the other side of the coin, we use power from the grid at night. This has allowed us to change our Powerwall settings to the time of use mode, which tends to push power back to the grid during peak grid usage periods, powering the house from the Powerwalls. The overproduction is exacerbated by COVID-19, as we are not driving nearly as much as before the pandemic. Conversely, in the summer months, it produces more than we need, resulting in a credit with our local utility. In the first few months as we exited winter, the system slightly underproduced versus our usage. In the first six months of production, we tracked the output of the system and it is producing enough for our needs. On the production front, the system silently cranks out power day in and day out. We opted for the solar roof because it was a more seamless product and was aesthetically better looking. Compared to a traditional rooftop solar system, the cost of our solar roof was effectively neutral. More than a justification of the Solar Roof purchase, the savings illustrate the base case for installing a rooftop solar system. When we installed our Solar Roof, my analysis estimated we would save more than $53,000 over 25 years compared to the cost of purchasing a traditional roof and paying for electricity from the local utility. The result is a product that produces a better return on investment and a more durable roof at the same time.

Integrating both lets Tesla tap into the money typically allocated for a traditional roofing system and the cost to install a residential rooftop solar system with a single product. The Tesla Solar Roof provides both a roof covering and a photovoltaic solar system in a single package. I compared offerings from Sunrun, Sun Power, sonnen, and Tesla before making what I felt was the best decision for my family and recommend you do the same. Tesla is just one of many solar providers out there, so don’t go with Tesla just because I did.

To run the numbers on a Tesla Solar Roof, Solar, or Powerwall for yourself in about two minutes, use my referral code ( ) and you can save $100. I unpacked everything I learned over the course of the installation in an article that walks through everything I think you should know before ordering a Tesla Solar Roof.Ī closeup look at the solar cells embedded in each of the solar producing tiles in version 2 of the Tesla Solar Roof. I unpacked the cost of the Tesla Solar Roof system compared to traditional systems at the time, but it’s worth noting that prices for the Solar Roof have come down significantly since then due to the aforementioned optimizations achieved with version 3. The result is a more durable roof that produces more power, can be manufactured at scale, and installed faster. The new system cranks out more power per roof tile and perhaps more importantly, does not require installers to cut any glass tiles to fit the system onto a customer roof. A few months after we inked our deal, Tesla launched version 3 of the Solar Roof, with larger tiles optimized both for manufacturing and installation. Version 2 used individual roof tiles and was really Tesla’s first attempt at making a scalable version of the solar roof product.
