SolarInstallationinCardiff

Cardiff's property market — centred around an average house price of £240,000 — is spread across approximately ~150,000 households throughout Wales. The mix of Victorian terraces, pre-war semis, post-war council stock, and modern new builds creates varied installation profiles. Roof pitch, orientation, material, and structural condition all factor into our MCS-compliant system designs, which are produced before each site survey using satellite imagery and then refined on the day by our certified surveyors.

Solar yield in Cardiff is approximately 900-950 kWh/kWp/yr kWh per kWp per year, based on 3.7 hrs/day avg of average daily sunshine across Wales. A south-facing 4kWp system will typically generate 3,300–3,600 kWh annually. Against a household consumption of around 3,500 kWh per year, that represents substantial self-sufficiency — particularly when paired with a battery that shifts daytime generation into peak evening demand. The Smart Export Guarantee (SEG) then pays an additional tariff for every unit you export to the national grid.

Cardiff has committed to a net zero target of 2030, and local planning authorities are broadly supportive of solar and heat pump installations under permitted development rights. Homes with renewable energy systems are also increasingly valued: a solar installation with battery storage typically adds 2–4% to property value according to estate agent surveys, while an improved EPC rating directly affects mortgage eligibility and future sale price under incoming MEES regulations.

Energy prices have roughly doubled since 2021, making the financial case for solar generation stronger than at any previous point in the technology's history. A 4kWp system costing £6,000–£7,000 installed and saving £900–£1,200 per year achieves payback within 5–7 years — then continues generating free electricity for 25 or more years. With ECO4 grants available for eligible lower-income Cardiff households and 0% VAT on solar and battery equipment, the barriers to entry have never been lower.
