Engineer. Futurist. Father.

I'm Dale Barnard.

Solar engineer, leader and technologist. I've spent more than a decade across renewables and digitalisation tackling climate-related challenges, and my children are what keep me motivated to solve them.

Independent engineering for solar and storage

In 2025 I founded Apex Renewable Engineering in Glasgow, an independent engineering practice for solar PV, battery storage and hybrid assets. It works for the lenders, investors, owners, developers and solicitors who need a straight answer: is the asset what it is said to be, what should it produce, and what happens when it doesn't?

I started in technical due diligence at SgurrEnergy in Glasgow, then spent seven years in Copenhagen on the other side of the table: designing utility-scale PV at European Energy, then, at Better Energy, building the systems that run an operating fleet, leading digitalisation and running plant engineering.

Apex Renewable Engineering

My independent engineering practice for solar PV, battery storage and hybrid assets: technical due diligence, asset health checks, portfolio reviews, owner’s engineering, contract review and expert witness work. Its two websites, the main site and a residential site for homeowners, are static sites I built and run on Cloudflare Pages.

ApexYield

A PV energy yield simulator built on pvlib. A Python engine does the modelling; a browser front end lays the system out on a site map, models shading in a 3D editor and produces PDF reports. It runs on Windows, macOS and Linux, and powers the free solar yield check on the Apex residential site.

NetAtlas

A self-hosted map of my home network. It finds every device on the LAN, names the manufacturer from its MAC address, guesses what kind of device it is, and draws the result as a top-down network diagram or an Obsidian-style graph.
