I’m not a big fan of traditional c-Si glass mounted panels using racks with roof penetrations.Ĥ. We do this now with Barrel Roof Tile and Flat Traditional Roof Tile. There are many areas on a roof that are concealed from the observer on the ground that can be embedded with flexible thin film without all the expense and complexities of a Tesla Solar Roof. The many connections this system takes with all its components just to make a claimed 30 year roof does not add up just so you can not distinguish a solar tile from a non-solar one. This creates obvious fodder for Workmans Comp issues.ģ. And I’m very concerned with the walk-ability on flat glass tile without texture on pitched roofs. Right now, all the versions of Tesla look like they turned the whole roof into a solar panel. That way, other manufacturers can use the technology to offer their own tile systems and we have variety. If you want to create scale, you should make designs that can be used by other manufacturers for scalability. I don’t like the fact that the design cant be used with other manufactured tile. Low life-cycle roofing systems with or without PV made with non-recycled materials doesn’t get us there.Ģ. I would like to think that the vast majority of people that support Tesla do so because they wish to save our Earth. Glass waste is already a big problem at the landfill and PV embedded complicates this even further. If the use of tempered glass was used to create a 30 year life cycle for the roof, this is a fail because 30 years is too short a life cycle for such a cost and would create a problem for sustainability via landfill issues. Tempered glass from Tesla cant come from recycled glass from the landfill and makes it difficult to fashion on the jobsite so you lose flexibility in the install. We actually made a traditional handmade barrel tile from recycled glass one year before Tesla made their first one and it tested to twice the break-strength of clay tile and at half the thickness. There are mountains of it waiting for secondary use at the landfill. If you’re going to use glass to make your tiles, they should be sustainable and be made from recycled glass. Oh I have a whole laundry list of things I find undesirable……Here are a few…ġ. So far, we’re very satisfied, but obviously very much looking forward to turning the system on.” Worked with me to get stuff right: like placing the inverter in a more appealing location. Took 7 days, they originally estimated 5.” He said, “Everyone was very professional. He told pv magazine that the “install went fairly smoothly. Twitter user Austin Flack provided a video of his solar roof tile installation that includes the economics of the roof tile along with a bonus drone crash. This installation, also in San Carlos, California is two or three days in, and had a crew of six men when I was there. The homeowners are documenting the install, which includes battery storage, here. The owner lauded the professional nature of the crew and expected about seven more days of work until the job is complete. There was a crew of five to seven people, including a separate crew for the Power Wall battery install. The old roof material has been removed, Firestone Clad-Gard SA-FR underlayment has been installed.Ībout half the tiles have been laid on this relatively simple roof. This installation in San Carlos, California is four days into the process. This requires a streamlined process of getting parts to the field along with assembly equipment to allow customization for flashing, edges and trim in the field. Musk said that the goal was to install the solar roof as quickly as traditional composition shingles - with a target of eight hours. He said, “The solar roof does not make financial sense for someone with a relatively new roof.”.Tesla intends to open up the product to roofing contractors.Musk said the goal is to install the roof in a single visit.The tiles now look the same from any angle - using new cell technology and new materials.The solar roof version 3.0 with larger tiles is ready for mass deployment.Late last year, Musk introduced version 3.0 of the solar roof tile and, with characteristic optimism, claimed that the company would ramp production to 1,000 roofs per week by December of 2019. It turned out that 2019 was not the year of the solar roof. Last year, Tesla CEO Elon Musk dubbed 2019 “the year of the solar roof,” its long-promised building-integrated photovoltaic product. This is an update of an earlier photo gallery. Pv magazine has been chasing down these installations, speaking to the homeowners, and taking photos. More than three years after its introduction, and after having received deposits from interested homeowners, Tesla has connected just a handful of solar-integrated roofs to the grid.
