We delivered a high-quality solar installation in Cardiff on a beautifully preserved period property with plain tiles 🏡
Thanks to the system’s efficiency and smart design, the customer is set to save an estimated £1,043 per year on their electricity bills, with a projected payback period of just 6 years 💷
The system comprises 18 Aiko modules totalling 8.5kW installed across three roof aspects, integrated with a Fox inverter with 3 mppts and a 5.2kWh battery to provide an efficient and future-proof energy solution ⚡

The team designing a bespoke residential system for a customer
Solar is a long-term investment — your system will be on your roof for 25+ years. So getting the design right from day one is crucial. That’s why our team starts every project with a precise 3D model of your property to engineer a system that perfectly fits your home and maximises your return on investment.
We map out panel layouts to make the full use of your roof space, testing different sizes and orientations, to ensure you roof captures its greatest generation potential. We analyse shading from chimneys, trees and nearby buildings so nothing compromises performance. And we run detailed generation estimates across multiple layout options so you can confidently choose the setup that delivers the greatest return for your budget.

We had the pleasure of completing this installation in a scenic part of Swansea this week.
Several options were explored with the customer during the design stage which included using the southwest roof only for 12 panels, both the southwest and northeast roofs for 24 panels and using no battery, a 6kW battery and a 12kW battery.
This customer went for the two roofs with a 6kW Solax TP30 battery, which is expected to generate 7,900kWh of clean electricity, and save them £1,300, every year.

A 19-panel system paired with 6kWh battery storage.
This system is projected to generate approximately 6,650kWh per year, and with intelligent battery storage in place, the homeowner is expected to go from paying around £90 per month in electricity to earning approximately £15 per month.
We maximised the available roof space by installing all 19 panels in landscape orientation. Interestingly, a neighbouring property with the same roof only had 16 panels fitted in portrait.
This is a perfect example of how a considered design makes a measurable difference. Those additional three panels are estimated to deliver at least £2,700 in extra savings over 25 years.

4theRegion Green Economy Conference, November 2025
It was brilliant to join the Green Economy Conference and connect with homeowners and businesses across Swansea, Pembrokeshire, Carmarthenshire and Neath Port Talbot.
Many people we talked to mentioned their worries about the ever increasing energy prices and were surprised when learning that a well-designed solar system can provide a return on investment in just 6 to 8 years, whilst still providing cheap electricity for another 15 to 20 years.
Valuable conversations, fresh ideas, and plenty of energy for a greener future.

We’re delighted to have completed another solar installation in Cardiff.
During the design stage, we explored no fewer than six different system options with the customer — carefully assessing roof configuration alongside projected return on investment.
Ultimately, they selected an 11-panel system without battery storage, tailored perfectly to their goals.
This is what sets us apart.
At Ulex Energy, we design and install bespoke solar solutions that match your property, your needs, and your budget. We don't use packaged, one-size-fits-all solar solutions.

We’ve just installed a powerful system featuring 16 high-performance solar panels — all perfectly positioned on a beautiful south-west facing roof for maximum generation — paired with a 11.6kWh battery.
This setup is expected to generate an impressive 4,900kWh per year, helping the homeowner save around £90 every month on their energy bills — with a payback period of under 7 years.

This installation in Uplands, Swansea has a total of 19no. Aiko 510W panels for a total of 9.69kW of solar.
The customer is planning to have a heat pump fitted so coupled the system with a 16kWh Fogstar battery to be able to cover their consumption most days of the year.
The system is expected to save the customer £113 per month and pay itself back in 6 years and 6 months.
