Frequently asked
Solar Panel Installation in Cardiff — common questions
QHow much does solar panel installation cost in the UK?
Solar panel installation typically costs between £5,000 and £12,000 for a standard residential system. Prices depend on system size, property location, roof condition, and installer experience. Most homeowners install 3-4 kW systems. The Government's SEG scheme and VAT reductions can offset costs. Get multiple quotes to compare.
QWhat affects the cost of solar panel installation?
Key cost factors include system kilowattage (kW rating), roof pitch and orientation, existing structural repairs needed, distance to electrical panel, battery storage addition, scaffolding requirements, and regional labour rates. Materials like panel efficiency ratings and inverter type also influence pricing significantly across UK regions.
QWhat does a solar panel installation service actually include?
Installation includes site survey, roof assessment, panel mounting system fitting, electrical wiring integration, inverter installation, consumer unit integration, meter installation, safety certificates, and commissioning. Professional installers also handle planning documentation, building regulation approval coordination, and system testing. Aftercare support and maintenance guidance are typically provided.
QWhat's the difference between grid-tied and battery storage solar installations?
Grid-tied systems feed excess power to the national grid for SEG payments, costing less but requiring grid connection. Battery storage systems store unused power locally for evening use, costing £3,000-£5,000 more but maximising self-consumption and providing backup during outages.
QWhat should I check before hiring a solar panel installation provider?
Verify installers hold MCS (Microgeneration Certification Scheme) accreditation and NAPIT electrical certification. Check they're registered with Trading Standards and hold public liability insurance. Review customer testimonials, request written quotes with breakdown, and confirm warranty terms. Avoid cash-only operators; legitimate traders invoice properly.
QHow long does solar panel installation take and when will I see savings?
Installation typically takes 2-3 days for standard residential systems. Systems generate electricity immediately but ROI takes 7-10 years depending on consumption and SEG tariffs. Annual savings range from £300-£600 for average households. Performance peaks during spring and summer months.
QDoes solar panel installation need a certified professional installer?
Yes, solar installation must be completed by MCS-certified electricians meeting Building Regulations Part P requirements. Electrical integration and safety certification are mandatory. Using uncertified installers voids warranties, breaches building codes, and disqualifies you from Government SEG payments and future grants.
