How Merthyr Tydfil compares
Among the places we publish figures for, Merthyr Tydfil is one of 32 Glamorgan towns we track, and it ranks 28th of 32 for solar yield. It is a medium town in the House of Commons Library classification, with 40,949 residents, and its roofs see 2.58 peak sun hours a day across the year. That drives the standard 12 panel model to 5,991 kWh of generation, of which around 5,054 kWh is exported at 12p for £607 a year, with £247 saved on electricity you would otherwise buy at 26.32p.

How to size a solar and battery system, properly
Usage, storage, connection, array. Four decisions, and the order between them matters.
Read the guide →Does a standalone battery actually pay back?
No panels means one job: buy cheap, use later. The tariff decides whether it pays.
Read the guide →Three phase and EV charging: what actually changes
Three phase buys 22kW charging. Most cars cannot use it, and load balancing usually solves the real problem.
Read the guide →How much does a heat pump cost? The 2026 numbers, before and after the grant
UK median installed cost around £12,908, before the up to £7,500 grant comes off.
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.
Read the guide →What MCS certification actually is, and why your export payments depend on it
The badge that decides whether your solar earns export payments. It cannot be added later.
