The seamless look of the new technology is thanks to “integrated front skirts and no visible mounting hardware” according to Tesla’s website. Electrek said these features come from Zep Solar, a mounting equipment company SolarCity acquired before Tesla’s acquisition. Zep Solar engineers designed the rail-less system Solar City employed to slash solar installation times in half.
Tesla says their panels “exceed industry standards for durability and lifespan” on their website. Panasonic will be manufacturing the exclusive panels at the Gigafactory 2 in Buffalo, New York. There aren’t many specifics available for the new solar panels yet, but Electrek said they will be 325-watt panels. They noted Panasonic sells other 325 watt panels, and those have a 25-year power output warranty and a 21.76 percent module efficiency.
If you visit Tesla’s website, you’ll find a very handy calculator that lets you estimate the cost of installing their new solar roof system. Here’s a sample calculation:
From a marketing perspective, I love how Tesla is shifting all the focus to the net benefit that an end-user receives. This is not at all unlike value-based fees for consulting services, a topic I’ve written about extensively.
Where else in the construction industry can one find pricing expressed in terms of the value delivered to the end user?
Instead of competing with every established roofing contractor in the country, and/or competing with every established solar installer in the country, Tesla has shifted the conversation to value that could only be derived from a single-source provider like Tesla. And last time I checked, there aren’t too many competitors in this space.
Great work disrupting the market, Tesla.
What About Risk?
The riskiest aspects of any roofing work on an existing residential structure include the following:
- Water intrusion from penetrations to the building envelope
- Reduced useful life of various building components due to improper manufacturing and/or installation
- Injuries to workers from safety violations, unsafe conditions, inadequate fall protection
- Injuries to people on the ground from improperly secured components on the roof
- Electrocution, other issues related to the presence of power-generating equipment integrated into the roofing assembly
A lot of the mitigation of those issues comes down to who will actually be installing the equipment. That topic is not addressed whatsoever on Tesla’s FAQs.
The real test of course will come once Tesla starts getting sued after their initial installations so that underlying liability coverage and contract language can be uncovered and examined more fully.
