Season 2 is officially LIVE! First off, a massive thank you to everyone who tuned into Season 1. Honestly, the number of views and listens we had was overwhelming. We started this to help the industry, and seeing how many of you got stuck in was the best motivation to get back behind the mics.

In this kickoff episode, we aren't hanging about. We’re diving straight into the "why" behind the new Hands-On Installer Training Day happening on April 23rd.

We know the accredited courses often leave you hanging when it comes to the actual graft. That’s why we’ve teamed up—myself, Mike, Ollie (Zinc Electrical), Sam (Oval Renewables), and the legend that is Mark Allison (Apprentice 1-to-1)—to get people on actual roofs. No fluff, just real-world mounting, clamping zones, and navigating the nightmare that can be the ENA portal.

What we cover in this one:

• Where we’ve been (including some jet-setting to China).

• Why "sandwiches and solar" is the training combo you didn't know you needed.

• Getting hands-on with tile, slate, and Rosemary roofs.

• Mastering G98/G99 applications and SolarEdge design tools.

• A sneak peek at what’s coming this season (Longi Solar and the new Sigenergy Neo).

Whether you’re a sparky looking to get onto the roof for the first time or a seasoned installer wanting to sharpen your tech game, we’re here to help you succeed.

Join us every Wednesday at 7 PM.

• How Apprentice 121 grew into a national training movement

• Why classroom-only solar courses miss the mark

• FIT retrofits with batteries, smart metering & commissioning quirks

• PAS guidance, large domestic storage & practical safety tips

• Gateways are coming – Tesla, SIG Energy, EcoFlow & more

• Battery recycling, packaging waste & sustainability

• SolarEdge vs SIG, Victron everywhere & manufacturer pitfalls

Three mics. One office. No filter.
Jay joins Mike & Dan back in the DMH HQ for a brutally honest chat about what life’s really like inside the business. From HGV driving to PV installs, broken panels, red-tape madness and why he’s still not trusted with the van keys — nothing’s off-limits.

This one’s half therapy session, half toolbox talk, all chaos.

What’s inside:

• £10k career switch and the training company that went bust

• Industrial vs renewables: real work vs red tape

• Storm-proofing gone wrong (and right)

• Josh the apprentice, the “whoever drives it washes it” rule

• That moment when the smart meter hits 0 kW ⚡

• Why renewables installers stick together tighter than duct tape

Heads-up: Recorded live in one room — bit of echo, plenty of energy.

In this episode of Only Panels, Michael and Dan are joined by Oli from Zinc Electrical to unpack one of the biggest questions in solar: how do you size a solar PV system properly?

We kick things off with highlights from Elex Coventry — including the Safe Isolate stand and plenty of installer chatter — before diving into real-world solar design.

Topics we cover:

• Should you design a solar system based on household consumption, maximise roof space, or stick to a set budget?

• The “120% rule” explained – why oversizing panels or inverters can actually improve performance.

• Inverter sizing myths: why a smaller inverter can sometimes generate more power over the year.

• Battery storage challenges – charge/discharge rates, hybrid inverters, and when to add batteries later.

• Real-life analogies to make sense of kWp, kWh, and inverter ratings (think: car top speed vs speed limit 🚗⚡).

• How to future-proof PV systems for EV charging, heat pumps, and growing family usage.

Oli also shares his personal journey: leaving corporate IT sales, training with Oval Renewables, and eventually launching Zinc Electrical. We talk about the realities of being a one-man-band installer, the importance of community in the UK renewables sector, and balancing business with family life.

Whether you’re a solar installer, an electrician moving into PV, or a homeowner thinking about solar panels and battery storage, this episode gives you practical insights into how systems are really designed — and why no two installs are ever the same.
