Tesla has launched the third iteration of its solar roof tile for residential home use, which it officially detailed in a blog post on Friday and in a call with media.
特斯拉推出了第三代家用太阳能光伏瓦，在周五的一篇博文和与媒体的通话中正式进行了详细说明。
Tesla CEO Elon Musk kicked off the call with some explanatory remarks on the V3 Solar Roof, and then took a number of questions.
特斯拉首席执行官埃隆·马斯克在通话中就第三代太阳能屋顶进行了解释，然后回答了一些问题。
The company says it'll begin installations in the coming weeks (Musk says some installations have already begun) and that it hopes to ramp production to as many as 1,000 new roofs per week.
该公司说未来几周将开始安装（马斯克说一部分已经开始安装），而且希望将产量提高到每周1000顶。
Tesla's solar roof tiles — which are designed to look just like normal roof tiles when installed on a house, while doubling as solar panels to generate power — are something of a work-in-progress.
特斯拉的太阳能光伏瓦安装在房顶上看起来就像正常的屋顶瓦片，同时又兼作太阳能电池板来发电，现在仍然是半成品。
The company is still tinkering with the product three years after announcing the concept, having done trial installations with two different iterations so far.
该公司提出这一概念的三年后仍然在对该产品进行改进，到目前为止已经试安装了两代产品。
"Versions one and two we were still figuring things out," said Elon Musk on an earnings call earlier this week, adding that he thinks "version three is finally ready for the big time".
本周早些时候埃隆·马斯克在业绩电话会议上说：“我们还在研究第一代和第二代产品，第三代产品终于可以大展身手了。”
Tesla's Solar Roof website now includes a pricing estimator, which lists $42,500 as the total price for the average 2,000 square-foot home, with 10kW solar panels. It also lists $33,950 as the price after an $8,550 federal tax incentive.
特斯拉的太阳能屋顶官网上现在有价格计算器，普通的2,000平方英尺房子的瓦片总价为42,500美元，带有10千瓦的太阳能电池板，联邦税优惠8,550美元后价格为33,950美元。
You can also enter your address and get an updated estimate that takes into account local costs and incentives, and add on any Powerwalls (with three as the default for a 2,000 square-foot roof).
你也可以输入地址，获取最新估价，会把当地成本和联邦税优惠考虑在内，还会算上Powerwalls家用电池（2000平方英尺的屋顶默认有三块电池）。
