☀️ Are your solar panels producing less this October?
Don’t panic—some seasonal change is completely normal.
As Southern California moves into fall, shorter days and a lower sun angle can reduce overall solar production compared with summer. But cooler temperatures can also help solar panels operate efficiently.
The important part is knowing what’s normal for your system—and what could signal an issue.
🍂 This fall, take a few minutes to:
☀️ Compare this October’s production with last October's
📱 Check your solar monitoring for alerts
🌳 Look for new seasonal shading
✨ Check for dirt, dust, and debris
🔧 Have unusual production drops inspected
New Day Solar has been helping Southern California homeowners get more from their solar systems for decades.
