Domestic Solar Panel InstallationChester, Deeside & North Wales

Cost depends on roof size, panel count and whether you add battery storage. A typical domestic solar PV system in the UK is commonly quoted between £5,000 and £10,000 installed, with larger arrays and battery storage costing more. MARA Electrical give a fixed written quote after a free solar survey, including a generation estimate and payback projection for your specific roof.

Most domestic solar panel installations pay back in roughly 7 to 12 years, depending on how much of the generation you use in the home rather than export. Panels typically carry 20 to 25 year performance warranties, so the system keeps generating long after payback. Adding battery storage raises self-consumption and shortens payback.

The Smart Export Guarantee (SEG) obliges larger energy suppliers to pay you for surplus electricity exported to the grid. Rates vary by supplier, so it is worth comparing. SEG payments require an MCS certified installation, which is one practical reason accreditation matters when choosing an installer.

For most homes, roof-mounted solar panels fall under permitted development and need no planning permission. Listed buildings, conservation areas and some flat-roof or ground-mounted arrays are exceptions. MARA Electrical confirm the position for your property during the free survey.

South-facing is ideal, but east and west-facing roofs still perform well — often around 80% of a south-facing yield, and they spread generation across the morning and evening rather than peaking at midday. North-facing roofs are not viable. We model your actual roof orientation, pitch and shading before quoting.

Yes. Photovoltaic panels generate from daylight, not direct heat, and actually run slightly more efficiently in cooler conditions. Cloudy days produce less than bright ones, but a well-designed system in Flintshire or Cheshire generates usefully across the whole year.

Battery storage stores daytime generation for use in the evening, which raises self-consumption and cuts more from your bill. It suits households that are out during the day. MARA Electrical model both options so you can see the numbers before deciding — read more on our solar battery storage page.

Yes. MARA Electrical are MCS certified solar installers and NICEIC approved electrical contractors, based in Queensferry on Deeside since 2010. MCS certification is required for Smart Export Guarantee eligibility and is the standard accreditation for domestic solar in the UK.
