Elon Musk, one of the world’s richest men, says a $50,000 abode near Brownsville, Texas, is his primary home these days. He has tweeted that he’s made some improvements to the house, without specifying what they are.

But earlier this year, Tesla Inc. employees traveled to Brownsville to install the company’s Solar Roof on that bungalow and several other houses on Weems Street that are owned by another Musk company, SpaceX. The construction project gave Musk an up-close look at a challenge that’s been vexing him.
