Solar Panels

A correctly designed system can significantly cut your electricity costs by generating free power during the day and reducing what you buy from the grid. Many households offset 40–70% of their annual usage, and even more when battery storage is added. The exact saving depends on system size, usage habits, and roof space.

System sizing should be based on your real energy consumption, not guesswork. At Plumbwise, we analyse your bills, roof orientation, and property layout to design a system that maximises return without overspending on unnecessary panels.

Yes. Solar PV generates electricity from daylight, not just sunshine. Panels still perform on cloudy days, making them highly effective year-round across Wales and the wider UK.

If you’re out during the day, a battery stores excess power for evening use, increasing savings and reducing reliance on the grid. It’s one of the fastest ways to improve system efficiency and long-term value.

Most panels last 25–30+ years with minimal maintenance. Inverters and batteries have shorter lifespans but are easily replaceable. A properly installed system delivers decades of reliable performance.

Very little. Panels are self-cleaning in rain, and we recommend periodic checks to ensure everything is operating efficiently. Monitoring systems also flag any issues early.

Most residential installs are completed within 1–3 days, depending on system size and complexity. We plan carefully to minimise disruption to your home.

Poor layout, incorrect sizing, or substandard installation reduces output and savings. A professionally engineered system generates more energy, lasts longer, and delivers a faster payback — which is exactly why we take a design-first approach.
