Sunrun stock falls 5% to a 52-week low ahead of Q3 earnings amid sector weakness.

Sunrun's stock dropped 5% to $6.93, hitting its lowest level in a year, while other solar stocks like Enphase Energy and First Solar also slipped but less sharply. The decline comes ahead of Sunrun's Q3 2026 earnings report scheduled for early November, which investors see as a key test for the company's growth and cash generation. Sunrun faces challenges from softer residential solar demand, policy uncertainties, and rising capital costs, but strong home battery storage demand and new grid programs offer potential upside. The upcoming earnings report will be crucial to gauge if Sunrun's expanded sales force is driving improved results.
