Overall many utilities are trying their best to dilute the value of a solar PV installation on one’s home. The ‘new’ bifacial solar PV panels may be much cheaper, easier to install, maintain, troubleshoot, than a “tile system” BIPV nail down system. When solar PV panels are mounted on a roof, there is usually at least a 2″ to 3″ air gap under the panels. The problem with direct nail down solar PV systems is the PTC rating of the solar PV product is affected by the lack of air flow to the underside of the tiles. RGS has ‘partnered’ with DOW on what they call the RGS POWERHOUSE 3.0 solar PV shingle. another company that took over where DOW tried to get into the market is RGS. IF TESLA is vague on costs, try a company named CertainTeed, they have the “Apollo II series” of solar PV roofing tiles. This installation included two Tesla battery units and three inverters, according to the home owners.Īlthough, solar PV “tiles” have been around since 2005 or so, there are some reasons, they have not caught on. Josh Pomilio, a Tesla solar glass crew lead, put up these version 3 installation photos on Instagram taken of a home in San Jose. Prepping for Austin Flack’s version 3 install. #solarglass #tesla #solarroof /hy21vicLkP Twitter user Austin Flack provided a time-lapse of his version 3 installation. According to Nikola’s Stache, these homeowners have pulled a permit for the version 3.0 roof. Here’s a roof that’s seen better days on a home in San Jose, California. Here’s another San Jose home with a version 2.0 roof. Here’s a version 2.0 installation in San Jose, California photo by author There were several piles of unused or scrapped tiles on the side of the home. This home in Los Gatos, California had V2 tiles on the roof and was undergoing a complete remodel. This installation included a Tesla battery. Here’s the version 3.0 roof in Cupertino, California. And so we’re scaling up production of the version 3 solar roof at our Buffalo Gigafactory.” He said version 3 is “finally ready for the big time. Musk said that Tesla “was still sort of figuring things out” with version 1 and 2. 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. Ginotra said that the goal was to install the solar roof as quickly as traditional composition shingles - with a target of eight hours. Kunal Ginotra, senior director of energy operations, said that Tesla has “increased the size and power density” of the tiles while changing some of the materials and reducing the number of parts and assemblies. 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. Twitter user Nikola’s Stache suggests that less than 100 solar roofs have been installed and only a handful of version 3 roofs are complete. Getting the exact number of solar roof installations from Tesla is difficult as Tesla press relations doesn’t relate to the press. 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. Musk’s second priority, “just as important, is that we immediately increase the rate of solar deployments by a significant degree,” said the CEO in the same memo. Tesla has a market cap of $94.5 billion as of today. Tesla built almost 105,000 cars in the fourth quarter and delivered roughly 112,000 vehicles - both records for the pioneering EV maker that have driven Tesla’s share price to new highs. It turned out that 2019 was not the year of the solar roof.Īt the end of 2019, Musk announced in a memo to employees that Tesla’s first priority was to deliver “all cars” by year end - before the expiration of Tesla’s EV tax credit. Last year, Tesla CEO Elon Musk dubbed 2019 “the year of the solar roof,” its long-promised building-integrated photovoltaic product.
