The number of solar panels you’ll need depends on three main things:
- How much electricity your home uses
- How much roof space you have
- The power output of the panels we install
🏠 Typical Household Example
A typical UK home uses about 3,000 to 4,500 kWh of electricity per year.
Using standard panels (around 400W each), most homes need:
| Annual Usage | Panels Needed | System Size |
| 3,000 kWh | 8–10 panels | 3.2–4 kW |
| 4,500 kWh | 10–14 panels | 4–5.6 kW |
🧠 But Here’s the Good News
At Sunmate, we offer a range of panel sizes and power outputs, so we’ll design a system that maximizes the energy you can generate—even if your roof is small or shaded in some areas.
That means:
- Fewer high-efficiency panels can be used if space is tight
- We customize the layout to match your roof shape and sun exposure
📌 Summary
Most homes need 8 to 14 panels, but we’ll tailor the system to your energy needs and roof size. The goal is to get you as close to 100% energy coverage as possible.
