On average, a typical UK home uses about 2,900 kWh of electricity per year. To cover this, most homes in Edinburgh would need a 3kW to 4kW solar system, which usually means installing 8 to 12 panels.

Each standard solar panel produces around 300 to 400 watts, depending on the brand and type. If you go for higher-efficiency panels, you might need fewer to meet your energy needs. If space is limited, you may be able to install fewer, more powerful panels.
Here’s a rough guide:
- Small home (low usage): 6–8 panels (around 2–3kW)
- Medium home: 8–12 panels (around 3–4kW)
- Large home (high usage): 12–16+ panels (5kW+)
Your roof’s direction and shading will also affect performance. A solar company in Edinburgh can assess your property and suggest the most efficient system. Local solar installers in Edinburgh will also help factor in your budget and whether you plan to add battery storage.
