Solar Panels for Homes Across Wales
Generate your own clean electricity, reduce your reliance on the grid and protect your home from rising energy prices with a professionally installed solar PV system.
Lower Bills. More Control. A Greener Future.
Residential solar panels help you generate electricity from daylight, reduce what you buy from the grid and make your home better prepared for future energy costs.
Lower Electricity Bills
Generate your own clean power and reduce what you buy from the grid.
Energy Independence
Use more of your own electricity and rely less on rising energy prices.

Residential Solar Panel FAQs
How much do solar panels cost in Wales?
Residential solar panel costs depend on the system size, roof layout, equipment selected and whether battery storage is included. A home survey gives the most accurate quotation.
How much can solar panels save?
Savings depend on how much electricity your home uses, when you use it, system size, export tariff and whether you add battery storage. A well-designed system can reduce grid reliance significantly.
Do solar panels work on cloudy days?
Yes. Solar panels generate electricity from daylight, not only direct sunshine, so they can still work across Wales on cloudy days.
Is my roof suitable for solar panels?
Roof size, pitch, orientation, shading and condition all matter. South-facing roofs are ideal, but east and west-facing roofs can also perform well.
Do I need planning permission?
Many domestic solar installations fall under permitted development, but listed buildings, conservation areas and unusual roof layouts may need extra checks.
Can I add battery storage later?
Yes. 3Phase can design many solar PV systems to be battery-ready, subject to the inverter, electrical setup and space available.
How long do solar panels last?
Solar panels are typically supported by long performance warranties, often around 25 years, depending on the manufacturer and system selected.
What is the Smart Export Guarantee?
The Smart Export Guarantee allows eligible homeowners to receive payment for electricity exported back to the grid through participating energy suppliers.
