Frequently Asked Questions
How much do solar panels cost in Wales?
Costs depend on roof size, access, system design and whether you add battery storage. We provide a clear quote after a home survey.
Can air conditioning heat as well as cool?
Yes. Modern wall mounted systems use air-to-air heat pump technology, so they can cool in summer and provide useful heating in winter.
Are solar batteries worth it?
They can be worthwhile if you want to store more of your solar generation and use it later in the day. Suitability depends on your usage pattern.
How long do solar panels last?
Good quality solar panels are designed to last for decades. We will explain product warranties and expected performance during your quote.
Can I get a grant for a heat pump?
Grant support changes over time. We can advise what is currently available and whether your home is likely to qualify.
Do you cover my area?
We cover homes across South, Mid and West Wales, including Swansea, Neath, Llanelli, Carmarthenshire, Cardiff and surrounding areas.
