December is supposed to be the cosy month. Fairy lights, hot chocolates, Christmas films, family time… and then bam – the energy bill arrives and ruins the vibe.
Because here’s the brutal truth:
Your energy bills don’t care that it’s Christmas.
But solar does, and it quietly works in the background to keep December from becoming financially painful.
If there was ever a month where solar proves its worth, it’s this one. Let’s break down how solar helps you stay festive, warm and in control while the grid does everything it can to drain your wallet.
🎄 December Is Basically the Olympics of Energy Usage
Families use more energy in December than almost any other month because:
- Heating is constantly on
- Evenings start at 4pm
- Kids are home more
- Cooking goes through the roof
- Laundry triples
- Christmas lights twinkle 12 hours a day
- You’re hosting, visiting, entertaining…
It’s adorable.
It’s chaotic.
And it’s expensive.
This is where solar steps in and plays Santa.
☀️ Solar Still Works in Winter, Even with Grey UK Skies
A lot of homeowners think solar switches off this time of year. It doesn’t.
December daylight still gives panels enough diffuse light to generate meaningful energy.
Typical output on winter days:
- Bright day: 30–40% of summer output
- Cloudy day: 10–20%
- Very dark day: small but still something
It’s not summer-level sunshine, but it’s enough to offset your most expensive daytime usage, the heating circulation pump, lights, TVs, chargers, appliances and more.
🔋 The Real Christmas Miracle? Your Battery
Solar is great in winter.
A battery is a Christmas lifesaver.
Here’s how it helps:
1. Stores daytime solar to use during expensive evenings
Use free solar power when you’re streaming Netflix under a blanket.
2. Works with cheap overnight tariffs
Charge the battery at 8–10p/kWh and avoid 30–35p daytime prices.
3. Powers all those festive extras
Christmas lights?
Slow cookers?
Heated blankets?
Hair dryers for party prep?
Your battery handles it.
4. Gives you energy stability during chaotic schedules
Guests unexpectedly staying over?
Big cooking days?
Battery’s got your back.
💷 What This Looks Like for a Typical Home in December
A 6 kW system + 10 kWh battery can save:
- £60–£140 in December alone
- Up to 70% of your grid usage
- £600–£1,200 over winter
Even if the panels don’t produce much on a particularly dark week, the battery + cheap-rate charging still reduces your bill.
That’s the magic:
Solar + battery gives you options.
The grid gives you none.
🎁 Solar Gives You Something the Grid Never Will: Control
December feels like a month where money just leaves your account uncontrollably.
But solar flips that feeling:
- You know what you’re generating
- You know what you’re saving
- Your battery is working while you sleep
- Your bills stay stable even when everyone else’s spike
It’s one of the few upgrades that actually makes December easier.
