The public first heard of Tesla’s intent to acquire SolarCity earlier this year. Despite the fact that the deal hasn’t officially closed, both companies are keen to demonstrate the potential of this collaboration. This made the most recent announcement, which happened yesterday evening, something that everyone was really looking forward to.
Elon Musk has already talked about what could be expected. Leading up to this big reveal, he spoke about creating a new roofing system that could redefine how we use solar power. It turns out, this will be directly integrated with the Powerwall 2.0, which will serve as the home energy storage solution.
This was discussed on the SolarCity blog:
Now is the right time to bring our two companies together: Tesla is getting ready to scale our Powerwall and Powerpack stationary storage products and SolarCity is getting ready to offer next-generation differentiated solar solutions. By joining forces, we can operate more efficiently and fully integrate our products, while providing customers with an aesthetically beautiful and simple one-stop solar + storage experience: one installation, one service contract, one phone app.
Just this week, during Tesla’s third quarter earnings call, Musk shared additional information about the new product, describing it as “impressive” and noting that it has exceeded his expectations.
The goal? To replace 5 million rooftops with Tesla’s more sustainable solar alternative.
Tesla Roofing System
At the event, Musk was surrounded by houses of many styles, all newly fitted with the solar technology. The roofing material has been designed to aesthetically match a few different roofing structures, such as French slate, flat modern, and even Tuscan style curved roof tiles.
From the ground, the tiles look like the tiles they are mimicking, but as they are viewed at a more extreme angle (such as that of the sun) they become more transparent. Musk stated, "The goal is... to have solar roofs that look better than a normal roof, generate electricity, last longer, have better insulation and actually have an installed cost that is less than a normal roof plus the cost of electricity."
During the unveiling, Musk also discussed an upgrade to the Tesla's Powerwall. The Powerwall 2 will cost $5,500 and will have double the capacity (14kWh) of the first generation product.
Majority of American homes use asphalt shingles for roofs. While cheap, its affordability does come at a price. They absorb heat, and aren’t very durable, and in terms of sustainability, they are fossil fuel based and are difficult to dispose. An affordable, environmentally friendly option would indeed be a welcome alternative.
Still, the availability of these alternatives, including Tesla’s new roofing system isn’t an all encompassing solution.
As Musk explained prior to the launch of his latest product, the system isn’t designed to be a retrofitted into existing homes. It’s designed for anyone constructing new homes or those planning to replace an aging roof. Other concerns, such as the need to install it at “latitude-appropirate angles,” or its durability when exposed to harsh elements, have also been raised.
