Solar Panel Installers Cardiff
Solar and battery systems sized around what your property actually uses, designed and installed by MCS-certified electricians in Cardiff.
Solar Panel Installation In Cardiff
Sized On Your Usage, Not Your Roof Area
We design from your consumption rather than the space available, because the largest array that fits on a roof is rarely the one that pays back fastest. Being MCS certified and RECC members means your system qualifies for export payments and the paperwork stands up when you sell.
Our solar panel services include:
- Solar PV design and installation
- In roof and on roof mounting systems
- Battery storage and retrofit batteries
- Hybrid and string inverter installation
- Solar diverters for hot water
- Smart Export Guarantee paperwork
- DNO notification and applications
- Consumer unit upgrades for solar
- EV charger integration
- Commercial rooftop and unit installations
Everything is commissioned, tested and handed over with the MCS certificate you need for export payments.
Considering Solar Panels For Your Property?
4 panels on a terrace or a full warehouse roof, no job is too big or too small for our electricians.
Solar Installations Across Cardiff & Nearby
Cardiff-based and MCS-certified, so the survey, the install and the aftercare all come from the same team.
We install across the whole city and out into the Vale.
Roof pitch, orientation and shading vary enormously street to street, and all three change what a system will realistically produce, so every quote follows a survey.

Battery Storage & Export
Using What You Make Instead Of Selling It Cheap
The economics of solar have moved. Exporting a unit earns you a fraction of what buying one costs, so the value now sits in using as much of your own generation as possible rather than in the size of the array.
That is what a battery does. It holds what you generate at midday for the evening when the house is actually busy. On a tariff with cheap overnight rates, it can also charge from the grid and carry you through the expensive part of the day, which works whether the sun shows up or not.
A solar diverter is the cheaper version of the same idea. Surplus generation heats your hot water cylinder instead of going out to the grid. Not as flexible as a battery, but a lot less to buy.
We will model what your own consumption pattern does with each option before you commit. Sometimes the honest answer is that a battery does not pay on your usage, and we would rather say that than sell you one.
Commercial Solar & Roof Space
Warehouses, Units & Business Premises
Commercial solar stacks up differently from domestic. A business that consumes most of its electricity during the working day uses far more of its own generation, which is exactly when a rooftop array produces. That makes the payback simpler than it is on a house that is empty until six.
We install on warehouses, industrial units, offices and retail premises across Cardiff, working with your roof structure and whatever the landlord or lease allows. Larger arrays need a DNO application before anything goes up, and we handle that rather than leaving it with you.
Where three-phase supply is involved, the inverter arrangement and protection change, and so does the metering. That is normal for the industrial units around Ocean Park, Leckwith and Rumney, and it is work we do regularly.
Everything is tested and certified upon completion, alongside any additional testing the premises require.
Frequently Asked Questions
Our Solar Panel FAQs
Do solar panels work in Wales?
Yes. Panels generate from daylight rather than direct sun, so cloud reduces output without stopping it. A properly sized system performs perfectly well on a Cardiff roof.
What does a solar installation cost?
Every roof is different, so we survey before quoting. Pitch, orientation, shading, scaffolding access, panel count, and whether you want a battery all change the work involved.
Do I need MCS certification?
You do if you want Smart Export Guarantee payments, and it makes the paperwork straightforward when you sell. We are MCS-certified and RECC members, so your install qualifies.
Can I add a battery to panels I already have?
In most cases, yes. It depends on your existing inverter, whether it is hybrid-ready, and whether there is space near the board. We can survey what you have and advise.
