Project Overview

CES Renewables has successfully completed another high-quality domestic renewable installation. This 6.8kW Solar PV system was designed for a flat roof application, delivering maximum efficiency and long-term performance for our customer.

System Details

  • 15 × 455W All-Black AIKO Panels
  • 9kWh SolaX Battery Storage
  • 6kW SolaX Hybrid Inverter
  • VanderValk Flat Roof Mounting System
  • Partial Shading Optimisation
  • Full Offsite Monitoring
  • MCS certified, NICEIC approved

This system combines efficient energy generation with advanced hybrid inverter
technology and battery storage, ensuring the homeowner benefits from reduced grid reliance and long-term energy savings.

Key Benefits

  • Lower electricity bills through self-consumption
  • Optimised generation despite partial shading
  • Increased energy independence
  • Full monitoring and control via the Solax app
  • Sustainable, future-proof home energy solution

Outcome

This project highlights CES Renewables’ expertise in designing and installing bespoke
domestic solar systems, combining cutting-edge technology, neat installation, and
professional certification. The result is a reliable and efficient solar PV system built to
perform for years to come.
