Enphase misses earnings estimates as weak home solar demand weighs on its outlook

Enphase Energy released its third-quarter 2026 results on October 27. The company supplies home solar equipment, including devices that convert solar-panel output into electricity homes can use; quarterly earnings were $0.41 per share, below analysts’ $0.47 estimate and $0.90 a year earlier.^[1][2]

Coverage of the results cited softer-than-expected US residential solar demand, persistent weakness in Europe and a disappointing fourth-quarter outlook. That outlook describes expectations for the next quarter; the results are still to come.^[3]

Interest-rate pressure is weakening US residential solar demand: for households borrowing to install a system, higher financing costs make electricity savings less able to cover monthly payments, potentially delaying purchases.^[4] As a benchmark for broader borrowing costs, the 10-year US Treasury yield rose to 5.05% on October 28 from 4.99% the previous session; solar loans carry their own rates.

Fewer installations mean fewer equipment purchases by installers and less revenue to cover suppliers’ fixed costs, such as factories and research. Enphase’s sales and margins declined, and operating profit fell 90%, showing how weaker demand is already reaching earnings.^[5] Weakness in both the US and Europe also limits the company’s ability to offset lost sales in one market with growth in the other.^[3]

Impact

What to watch next

• The September core PCE price index, which excludes food and energy, is due October 29. A 0.3% monthly rise is expected, versus 0.2% previously; a hotter reading could reinforce expectations of sustained high rates, making relief in solar financing costs harder to achieve.
