Solar in KY12: roof size may be the main upside, so compare proposed system sizes carefully.

This is a modelled local view, not a promise of savings. Use it as a quick sense-check before comparing installer quotes for KY12.

Why KY12 differs

South-facing yield is about 3.8% above the Southern Scotland median.

The starting system size is close to the regional typical size at 6.0 kW.

Battery payback depends heavily on evening use, export tariff and whether the installer has assumed optimistic self-consumption.

How we calculate this

Solar generation: Based on typical south-facing roof at 35° angle. We account for weather, dirt, and system losses (14%).

How much you'll use directly:

  • Without battery: You'll use about 40% of what you generate. The rest gets sold back to the grid.
  • With 5 kWh battery: You'll use about 70% (battery stores extra for evening use).
  • With 10 kWh battery: You'll use about 75% (more storage means less exported).
  • Panel-only payback: The official cost per kW is lower above 4 kW, so a 5–6 kW system can pay back a little faster than a 3–4 kW system on otherwise identical assumptions.
  • Battery & payback: Batteries raise self-use and cut bills, but added hardware cost often lengthens break-even at typical UK rates.
  • When a battery can still make sense:
    • Evening-heavy usage patterns
    • Time-of-use tariffs / cheap night rates
    • Low export rate vs. high unit rate
    • Heat pump or EV charging synergy
    • Optional backup/resilience (system-dependent)
    • Lower evening-hour CO₂ vs. grid

Panel costs: Uses March 2026 TIC mean installation costs: £1,827/kW up to 4 kW and £1,628/kW above 4 kW.

Other costs: Battery prices are modelled at £700 per kWh. Export tariffs vary by supplier (usually 5–15p per kWh).

Grid connection: Systems up to about 3.7 kW typically need just a notification (G98). Larger systems may need permission (G99).

These are typical values based on average usage patterns. Your actual results will vary based on your roof, shading, and how you use electricity.

Before you sign

What to challenge in solar quotes for KY12

Use the calculator above as a baseline, then ask installers to explain where their quote differs from the local assumptions.

If the proposed system is much larger than 6.0 kW, ask why it fits your roof and usage.

Compare payback with and without a battery before accepting a bundled quote.

Check which Smart Export Guarantee tariff is assumed. The calculator baseline uses 10p/kWh.

Confirm who handles MCS certification and DNO/G98/G99 paperwork before comparing finance or warranties.

Your area in context

In Southern Scotland, the current unit rate is 25.85p/kWh with a 64.17p/day standing charge. Your postcode’s south-facing sunshine yield is 882 kWh/kW — 32 above the regional median (850).

Read the full story

A typical roof here lands around 6.0 kW, with most eligible homes comfortably fitting within 3–6 kW. Each kilowatt of panels produces roughly 882 kWh per year on a south-facing roof. We value self-used electricity at 25.9p and exported surplus at a baseline 10p via SEG. Use the calculator above for your exact tariff.

For each system size (2–8 kW) we show annual output, how much you use directly, what gets exported, annual benefit, upfront cost, break-even, and a 20-year net. Negative numbers are possible — that’s the honest trade-off when adding more battery than your usage profile justifies.

Winter output: 41.0% of an average month (Dec–Feb)

Best / worst month: May / Dec

These figures show output per kilowatt (kW) of panels installed. In winter, a 1 kW system here produces about 30 kWh per month; the average month produces around 73 kWh. So a typical 4 kW home system would generate roughly 121 kWh in winter, or 294 kWh in an average month.
