Plug-In Solar After the Clocks Change: October UK Guide
The clocks go back in October and daylight drops. Here's how to adjust your plug-in solar setup for shorter days.
The October Shift
When the clocks go back (last Sunday in October), sunset moves from ~6pm to ~5pm. Your solar system loses roughly one hour of evening generation, and morning start-up is earlier in clock time.
Output Expectations
| Period | Daily output (800W, Midlands) |
|---|---|
| Early October | 2.0-2.5 kWh |
| Late October | 1.4-1.8 kWh |
| November | 1.0-1.5 kWh |
The drop from summer (~3.5 kWh/day) is noticeable but gradual.
Adjustments to Make
Shift Load Schedules
If you've been running washing machines at 1-2pm, move to 11am-1pm. The solar peak narrows and shifts earlier in autumn.
Increase Panel Tilt
If using adjustable brackets, increase tilt by 10-15° from summer angle. The lower sun benefits from steeper panels.
Self-Consumption Gets Easier
Ironically, lower generation means less export waste. Your self-consumption ratio may actually improve in autumn — you use a higher percentage of what you generate.
Monitor for New Shading
Trees still in leaf combined with low sun angles create new shading patterns. Check if nearby vegetation now casts shadows that weren't there in summer.

Is October output worth worrying about?
Yes — October alone generates ~50 kWh (800W, Midlands), worth roughly £7 in savings. Small but cumulative.
When does solar really drop off?
November-January is the low period. From February, generation recovers quickly. See our monthly performance guide.
