Handover day for this completed full install in Tregony.
Our client went for 16 x 430w Longi all black PV modules, retrofitted in roof using GSE trays, aarcBox MC4 enclosures, powering a 13.5kWh Tesla Powerwall 3 with backup gateway, and a Tesla Wall Connector EVSE.
This all integrates into the clients Tesla app, where they can also see their Tesla EV stats, all on the same platform.

This was available great project to work on, which will now see my client with reduced bills and higher energy independence ☀️🏡

Myenergi Libbi install day, assistance provided by my 13 year old son Harry 💪🏼
Today we installed a 5kW Libbi inverter with 2 x 5.12kWh battery storage modules, in preparation for the 7.2kW of Solar PV modules to go on the roof which will follow soon.
We also used the new Proteus DC combiner box, with pre-made DC isolators and DC SPDs in an enclosure, this saved so much faff, so we will be using these going forward 👌🏼
It was great to have Harry with me and have him getting stuck in with the job, and showing a real interest in what his dad does for a living 🙂
Fuel for Harry provided by hot chocolates from CEF 🤣

Last job of 2025 saw the install of a 10.24kWh MyEnergi Libbi Battery system to transform an 11 year old Solar PV install.
As the existing inverter was faulty, this was a perfect time to upgrade.
We replaced the FIT meter for a NET type to allow our customer to continue to receive there FIT payments, as well as be able to charge off peak.
A very smart and neat install makes flr a happy customer 🎄☀️🏡

Our Tredrizzick job is nearing completion, and what a beauty it is 🤩

This stunning extension features 10 x 450W Viridian in-roof modules, powering a 3.68kW MyEnergi Libbi paired with 2 x 5.12kWh battery storage modules — a modest install that still packs a serious punch while looking the business 👌🏼

The Libbi continues to impress:
• Smart, modular battery storage that grows with the customer’s needs
• Seamless integration with the full MyEnergi ecosystem
• Excellent energy optimisation, keeping more solar power in the home
• Intuitive app control, making it easy to monitor, manage & maximise savings
• Reliable backup power options, boosting energy independence

We’ll soon be wrapping up with a MyEnergi Zappi 2 EVSE and an Eddi smart hot water controller, completing a clean, modern, and energy-smart setup ☀️🏡

Hello! We are fundraising for Watergate Bay Surf Life Saving Club. Here’s our JustGiving page, if you’d like to donate any amount it would be gratefully received.

These funds go towards training our lovely bunch of kids in essential beach safety, arming the with the skills to become the lifeguards of tomorrow.

We also use these funds to train our adults with coaching qualifications and water safety courses such as lifeguard awards to be able to cover our club sessions, and, as the club moves forward to provide evening patrols when available when the RNLI are off duty.

Shoulders are still burning after last nights long paddle to Beacons Cove from Watergate Bay SLSC HQ.
Sea was flat, low tide and with 4/5ths of the club on holiday it was the perfect time for a bit of exploring 💪
Unfortunately no one thought to bring a Go Pro or camera so the only evidence is the fact that my arms (and everyone else’s ) are out of order today 🤣
Swift drink after in WAX Watergate Bay (thank you for the hot chocs for the kids) to finish the evening off 👌🏼

First Tesla Powerwall 3 in and operational 🙌

This month we finally got our hands on our first Powerwall 3, which got this 7.83kWp East/West system in Newquay up and running.
We installed with the Tesla Gateway 2, which allows whole home backup and energy monitoring.
As part of our package we also upgraded the old 90s plastic consumer unit for a new 18th edition consumer unit with 30mA RCBOs and carried out an electrical test.
Happy client now can run their house from either generated PV power, or from cheap off peak energy by charging over night on a cheap tariff.

If your thinking of going for Solar PV, Battery Storage, EV Charger or any general electrical work send us a DM and we can help you on your journey today 👌🏼
