Residential Solar PV Flat Roof Installation

CT Walters Electrical completed a challenging domestic solar PV and battery storage installation at a private residence in Oxford, delivering a carefully designed solution tailored to the property and the client’s long-term energy goals.

The project involved a 10kWp flat roof solar PV system, installed using a non-penetrative, ballasted mounting system to protect the roof structure while ensuring long-term stability. The system was paired with 20kWh of battery storage, significantly increasing self-consumption and providing a high level of energy independence throughout the day.

Due to the complexity of the installation, the project required close coordination with a structural engineer, ensuring every aspect of the design and installation met the highest technical and safety standards.

Client Testimonial

“What’s the best solar solution for a flat roof? What size of battery would be optimal? How best to configure with an Air Source Heat Pump? These aren’t straightforward questions, and there’s a bewildering amount of conflicting information out there.

CT Walters were recommended to us and helped us break things down step by step in a way that enabled us to make straightforward decisions through the whole design, installation and commissioning process.

We wanted confidence in good customer support, a high-quality job and an installer who will still be there in years to come. We couldn’t praise Danny Kelly and the team more highly. Every wrinkle was ironed out, everything delivered to the highest standard, and the system works beautifully — effectively taking us ‘off grid’ for much of every day.

While CT Walters Electrical Ltd weren’t the cheapest, we feel we received excellent value for money and would highly recommend them to others.”
