特斯拉于8月停止供应太阳能屋顶产品，转而仅提供传统太阳能电池板，这一突然决定给第三方认证安装商造成了重大经济损失1。这些承包商为支撑该业务投入了数十万美元用于员工培训、工具购置和人员配备，但该产品在七年内的实际装机量远未达预期1。
根据安装记录，太阳能屋顶系统七年来仅安装约3,000套，最高周装机量仅为21至32套，与马斯克曾承诺的周装机1,000套目标短缺超过95%1。这种巨大差距反映出该产品商业化进展的严峻现状。与此相比，传统太阳能系统仅需两天安装完成，而太阳能屋顶则需要两周多时间1。特斯拉曾要求承包商完成多周培训和三次受监督安装才能获得认证资格1。
对于现有客户，特斯拉表示将继续兑现现有保修并提供更换零件1。然而，承包商对产品在25年保修期内的长期零件供应前景仍持怀疑态度1。特斯拉内部评估认为太阳能屋顶"在财务上不可行"1。
Tesla halted supply of its Solar Roof product in August, shifting to offering only traditional solar panels instead 1. The abrupt decision has devastated third-party certified installers who invested hundreds of thousands of dollars in training, equipment, and personnel to support the product line 1. Over seven years, the Solar Roof program yielded only approximately 3,000 installed systems, with peak weekly installation rates reaching just 21 to 32 units—falling more than 95 percent short of Elon Musk's promised target of 1,000 weekly installations 1.
The installation process for Solar Roof systems is substantially more labor-intensive than conventional solar alternatives, requiring over two weeks per project compared to just two days for traditional systems 1. Contractors must also complete multi-week training courses and three supervised installations before obtaining certification 1. Tesla has stated it will honor existing warranties and supply replacement parts, though installers remain skeptical about long-term component availability within the 25-year warranty period 1. Internally, Tesla determined that the Solar Roof product was "financially unviable" 1.
