| System size | Typical cost | Annual generation | Annual saving (est.) | Payback period (est.) |
|---|---|---|---|---|
| -3.2kWp (2-bed) | £4,000–£6,500 | -2,368kWh/yr | £-406 | ~-12.9 yrs |
| 2.4kWp (3-bed) ← typical | £4,500–£7,500 | 1,776kWh/yr | £885 | ~7.5 yrs |
| 3.5kWp (4-bed) | £6,000–£10,000 | 2,590kWh/yr | £444 | ~18.0 yrs |
Cost ranges sourced from MCS guidance, Which? research, and Energy Saving Trust estimates (2025 figures). Annual saving assumes export tariff (SEG) plus self-consumption at current Ofgem unit rate of 24.5p/kWh. Individual results vary based on roof orientation, shading, occupancy, and energy usage patterns.
What Affects Solar Panel Costs in Edinburgh?
Several factors influence the final price of solar panels for a 3-Bedroom House in Edinburgh. The region records around 1258.0 hours of sunlight per year, which determines how much electricity your panels will generate. This translates to a generation rate of approximately 740.0kWh per kWp installed annually in this area.
Roof orientation is one of the biggest cost-efficiency variables. A south-facing roof at a 30–40° pitch achieves optimal output; east or west-facing roofs typically produce 15–20% less. Shading from trees, chimneys, or nearby buildings can significantly reduce yield and may require micro-inverters or power optimisers, adding to the system cost.
Roof type and accessibility also affect labour costs. A simple pitched tile roof is straightforward to work on; slate, flat roofs, or awkward access points require additional equipment and time. For a 3-Bedroom House in Edinburgh, you should expect typical quoted prices to fall within the ranges shown above, though the final cost will depend on your specific installation requirements. Always obtain at least three quotes from MCS-certified installers.

Solar Panel Grants in Edinburgh — 2026
Several UK government schemes can reduce the cost of going solar in Edinburgh. These change regularly, so always check gov.uk for the most current eligibility criteria and amounts before making any decisions.
ECO4 (Energy Company Obligation) — Available to households on certain benefits or with a low energy performance rating (EPC D or below). This scheme funds energy efficiency improvements including solar through your energy supplier. Eligibility is means-tested.
Great British Insulation Scheme — Primarily focused on insulation, but homes improved under this scheme often become better candidates for solar as their overall energy efficiency improves. A warmer, better-insulated home makes solar investment more effective.
Boiler Upgrade Scheme (BUS) — If you are also considering a heat pump alongside solar, the BUS grant provides significant support. Solar and heat pump combinations are increasingly popular as they work well together. Check gov.uk for current BUS grant values, as these are revised periodically.
Smart Export Guarantee (SEG) — Not a grant, but an important income stream. Every licensed electricity supplier with more than 150,000 customers must offer SEG tariffs, paying you for electricity you export to the grid. The figures in our savings estimates above include a modest export contribution.
