Alectrona
Engineer-led solar & battery storage · YorkshireA 25-year asset deserves more than a sales call. We design, install and stand behind solar PV, retrofit battery storage and commercial systems, with the engineering shown, not hidden.

Alectrona is the residential and commercial PV arm of RVTC LTD, built and run by an engineer rather than a sales operation. Its sister arm, Solar Tech Support, is the UK's busiest independent solar diagnostics service, so every Alectrona install is informed by what actually fails in the field.
Prices stay low because the operation is lean: in-house warehousing and logistics, no commissioned sales reps, and trade discounts secured by buying in volume. The saving goes to the customer, not a sales team. Every quote is fully turnkey, one fixed and itemised price inclusive of VAT, scaffolding, DNO and Building Control.
No pressure-selling, no deposits, and prices set out plainly. The balance is only due once the system is installed and demonstrated as generating to your satisfaction. That is how confident the work stands behind itself.
One accountable engineer behind every design, survey and sign-off. No commissioned advisors, no disappearing subcontractors.
No field sales reps, in-house warehousing and trade discounts secured by buying volume.
Every system sized from your real usage, with the components and the reasons for them set out in writing before you commit.
Latest-generation panels and inverters, only from manufacturers that respond properly under warranty.
In the old Rhodian telling, Alectrona was a daughter of Helios, the Greek sun god, honoured as a goddess of the morning sun.
We took the name on purpose. Solar is sunlight made useful, and a name worth living up to keeps the bar high: engineered with care, built to last, and honest about what the sun can do for you.
We fit the brands we trust to last and know we can support: manufacturers that respond properly under warranty and ship parts in days, not weeks.
MC4 plug-and-socket connectors are the #1 fault category in the UK installed base, diagnosed in real time through our sister company Solar Tech Support. Every man-made MC4, the connectors we crimp on site, gets a sealed ArcBox enclosure: weatherproof, UV-stable, and proof against the arcing-on-corroded-pins failure that causes most rooftop fires. The field-made connectors are where the risk lives, so those are the ones we seal.
Where the cable run permits, we use PV Ultra: TÜV-certified to EN 50618, double-insulated, UV and ozone rated. It costs more than the bare-minimum H1Z2Z2-K most installers fit. Over a 25-year design life that price difference is the right call every time, and the only one our engineers will sign off.
Our Qualifying Supervisor, a qualified electrician, personally reviews the install report on every job before commissioning sign-off. Photos, test certificates, torque-check log, commissioning data: all filed, checked, signed. We are an engineering company first, so every install gets a second pair of trained eyes. The installer never signs themselves off.
Retrofit a battery to almost any existing solar system, any inverter brand, usually in a day. Keep your daytime solar for the evening instead of selling it back cheap.
A properly engineered home solar system, sized to your roof and your usage, with the components and the reasons for them set out in writing.
