Elon Musk is no longer leading the charge in residential solar.

Tesla Inc. installed 87 megawatts of commercial and residential solar in the fourth quarter, including about 50 megawatts at homes, according to a GTM Research estimate. Rival Sunrun Inc. added 85 megawatts of residential systems in the same period, according to a statement Tuesday. Counting only that part of Tesla’s operation, Sunrun took the lead in the third quarter.
