Our Expertise in Commercial Solar Installation

At Craftex Design & Construction, we deliver complete solar solutions for commercial spaces — from planning to installation — helping businesses reduce energy costs and transition to clean, reliable power.

As experienced commercial solar installers, we ensure every project is designed for maximum efficiency and long-term value.

  • Solar PV Design & Engineering

    We carry out site assessments and create custom system designs based on your building layout, energy usage, and future requirements.

  • Roof-Mounted & Ground Solar Systems

    Our team installs solar panels on flat or pitched rooftops, as well as ground-mounted systems where roof space isn’t suitable, ensuring safety and compliance.

  • Battery Storage Integration

    We offer integrated battery storage options to help businesses store unused solar energy for later use, improving energy efficiency and resilience.

  • Grid Connection & DNO Approvals

    We handle all paperwork and coordination with the Distribution Network Operator (DNO), making sure your system is connected to the grid and ready for export.

  • System Monitoring & Maintenance

    Our service includes ongoing support, system checks, and performance monitoring to ensure your solar setup continues to deliver value over time.

  • EV Charging & Renewable Integration

    We provide end-to-end EV charging point installations and integrate them with your solar system—offering sustainable energy solutions that future-proof your business and reduce carbon footprint.

How We Work (Process)

Gaining a thorough understanding of your commercial premises including any obstacles to business success, we begin to formulate ideas for your space in-line with your timescales, goals and budget.

Taking into account your objectives, we deliver well considered, innovative design proposals for your consideration.

From costing to minimising disruption to your normal business functions, we create highly detailed plans on the agreed scope of works to ensure all elements of the project are in line with your expectations.

Reducing disruption via detailed planning and attention to pre-agreed timescales, suppliers and contractors get to work delivering a shared vision for your premises.
