A common question we get at Keenan Solar is: “Can solar panels actually power my whole house?”
The short answer is: Yes — with the right system and battery setup, most North London homes can be 80–100% self-sufficient.
Let’s break down how it works.
☀️ How Much Power Do Solar Panels Produce?
The amount of electricity your panels generate depends on:
- System size (number of panels)
- Roof direction & tilt
- Shading from trees or nearby buildings
In North London, a well-positioned 4.5kW solar system can generate around 4,500–4,800 kWh per year — roughly the same as the average household’s annual energy usage.
🔋 The Role of Battery Storage
Without a battery, your solar system powers your home during the day but sends unused energy back to the grid.
With a battery, you can:
- Store that excess energy to use at night
- Power key appliances 24/7
- Cut your grid reliance by up to 90%
This is how homes in North London achieve almost complete energy independence.
🏡 Real Example – Enfield, North London
- System: 16 panels + 5kW inverter + 10.2kWh EcoFlow battery
- Annual Usage: ~5,000 kWh
- Solar Generation: ~4,800 kWh
- Grid Reliance: Only 12%
- Savings: ~£1,150/year
The customer runs their lights, appliances, and even EV charging from solar power for most of the year.
💷 Bonus Tip – Combine Solar with a Smart Tariff
Pairing your battery with a smart energy tariff like Octopus Flux or Agile allows you to:
- Charge from the grid overnight when rates are cheap
- Sell back excess power during high-rate times
- Further reduce your bills year-round
