What to expect at our Cardiff showroom

A proper sit-down

Sit down with the team and talk through your home, your bills and what you'd like from solar. Bring a recent energy bill and we'll work out your own numbers.

See the kit up close

Have a look at the Tesla Powerwall display, the panels and the other kit we fit, and ask anything. It's much easier to picture once you've seen it in person.

No pressure to decide

There's nothing to sign on the day. Take your figures home, think it over and compare quotes if you like. We'll go through it together, and you decide.

Easy to find in Whitchurch

We're at 11 Penlline Road in Whitchurch, open weekdays and Saturday mornings. Book a time that suits you, or give us a ring first if you'd like a chat.

Come in and see your potential savings

Every home is different, so we won’t pretend there’s one number that applies to everyone. 
As a guide: a typical terraced house with six panels and a small battery might save around £1,100 a year, while a large detached home with a bigger system can save £2,900 or more. Payback usually lands between four and seven years, and the panels keep working long after that.

The only way to know your number is to look at your home, your roof and your bills, which is exactly what our free Return on Investment Assessment does. There’s no obligation attached, and if the numbers don’t work for your property, we’ll be the ones to tell you.

What our Cardiff customers say

Rated Excellent on TrustpilotRated 4.9 to 5 stars on Google

“What makes them standout from other Cardiff based suppliers is the showroom in Whitchurch.”

“We got several quotes and these guys were head and shoulders above the rest in their approach. The end result looks very smart - the quality of the install really is top notch”

“The team at Solar House Cardiff were superb from start to finish. From the initial consultation and design accommodating our needs, to finding a solution to the cable runs. The install ran smoothly, and the after care has been great too”

“I contacted them, arranged a meeting, they explained everything clearly answered questions on every level and followed up with a quote. No hard sales during or after the meeting.”

“Truly amazing service from The Solar House, from start to finish they answered all my questions, helped me with every decision and provided a great level of service. The install itself is amazing and has exceeded my expectations.”

“A great experience from my initial enquiry at the shop in Whitchurch, through to the survey and then the install. Everything was arranged and communicated well, scaffolders turned up when they were supposed to.”

“Dan took the time to invite us into the showroom and explain everything clearly and professionally. There was absolutely no pressure selling, just honest advice and guidance, which we really appreciated.”

Questions before you visit

Not a salesperson. If you decide to go ahead after your showroom visit, one of our team carries out the survey. On installation day you'll meet our electricians, along with the roofing and scaffolding teams we work with, and your project manager stays your single point of contact from start to finish.

Our electricians are qualified and we're an MCS-certified installer and NICEIC approved contractor, so your system is designed and installed to the standards needed for warranties and export payments. We're also a Tesla Powerwall Certified Installer.

The scaffolding usually goes up a day or two before. On the day, the roofing team fits the panels while our electricians install the inverter, battery and any EV charger. Your power is off for a short time while we connect everything, and most installs are finished within a couple of days.

We treat every home as if it were our own. The team protects floors and furniture where they're working, keeps the site tidy and clears up properly before they leave. Cable routes and equipment positions are agreed with you at the survey, so nothing comes as a surprise.

Your showroom visit is free and there's nothing to sign on the day. If you'd like to go ahead, the survey comes next, then a clear quotation for the whole project. There are no discount deadlines; take your quote, compare it with others and come back if it makes sense for you.

Getting the panels on the roof isn't the end of the job. If a question pops into your head six months later, about your app, your bills or adding a battery, ring us or drop into the showroom. You'll speak to people who answer the phone and know your system.
