How Helensburgh compares
Small towns rarely get published solar figures, so here are the numbers for Helensburgh. It is one of 7 Dunbartonshire towns we track, and it ranks 6th of 7 for solar yield, a town of 14,053 people in the House of Commons Library settlement data. PVGIS gives its roofs 834 kWh per kWp a year, 2.29 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £771 of year one benefit, £247 of it from your own generation and £524 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Helensburgh's own yield, and at Helensburgh's 834 kWh per kWp it prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
Planning applications here go through Argyll and Bute; nationally, the House of Commons Library classes Helensburgh as a small town.
The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.

G98 vs G99: the 28-day form and the eight-week wait, in plain English
One number on your quote decides between a formality and an eight week wait.

Usable capacity, kW output, round trip losses and chemistry, in plain terms.

Why your charger arrives pre-set to charge overnight, and why it waits before it starts.
Read the guide →Heat pump running costs versus a gas boiler, assumptions shown
Four numbers decide it: seasonal efficiency, flow temperature, tariff and heat demand.
Read the guide →The price cap explained, and what it does to solar payback
The cap limits unit rates, not bills. That changes what solar payback means.

A logo proves nothing. Certification is business specific, technology specific and checkable.

Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
