Alectrona
ContactSend your site address and twelve months of half-hourly consumption data. An engineer models your roof against your own load and sends back a report with your figures in it. No charge, no site visit, no obligation attached to receiving it.
A real engineer reads every enquiry.
Your enquiry goes to the engineering team rather than a call centre. If something is missing we ask one short question by email instead of booking a call to find it out.
Usually within one working day
From your address and your half-hourly data the array is set out across the usable roof planes in PV*SOL and run against how the site actually draws power across the year, rather than a generic profile.
Desk work, nobody visits
Indicative system size, the generation the array should produce, how much of it your site would use rather than export, and an early read on whether the connection is what caps the size. Yours to keep and circulate.
Free, and yours either way
If the report reads well, the next step is the measured on-site 3D drone survey and a fixed price against a designed scope. If it does not, you have your answer, and we will say whether the roof, the load or the connection decided it.
Your call, in your time
Each one takes a guess out of the model. Send what you have and we will tell you what is missing.
The address lets an engineer pull the roof from aerial imagery and read its rough size, orientation, pitch and the obvious shading. It also fixes which distribution network operator sets your connection terms, and that is often what caps the system size.
Anything showing the roof will do: an as-built plan, a lease drawing, a photograph from the yard, or the pin you dropped on a map. Rooflights, plant, parapet set-backs and access zones take real area out of a roof, and a plan shows them long before a survey does.
On a commercial site the return comes from the power you use on site rather than the power you export, and only your half-hourly demand profile shows which is which. Your supplier or broker can release it for a metered commercial supply.
No qualifying call to sit through, and nobody will visit at this stage.
Alectrona is the commercial arm of RVTC Installations Ltd, and it is deliberately small. The person who reads your enquiry is the person who models the roof, and the same team carries the design through the grid connection, the installation and the maintenance afterwards, which is how a project runs from end to end. Nobody here earns a percentage of what you sign, so there is no incentive to talk you into a bigger array than your load can use.
It also means we say no when the answer is no. Three findings end a commercial project: a roof needing strengthening that costs more than the solar saves, a connection with no headroom for the export the array would produce, and a load sitting outside daylight hours. The remote survey tests all three, and it is cheaper for both of us if one of them surfaces at the desktop stage.
The same team that quotes the system is the team that maintains it.
If one of these is you, there is a better page to start from than the form.
If the firm that built your array has folded or stopped answering the phone, the system can be adopted: diagnosed first, put right, then carried forward under a written maintenance contract so the asset has an accountable owner again.
System takeoverFor procurement officers, estates teams and sustainability leads: what a solar specification should ask for so the bids you score are genuinely comparable, and how we respond to one.
Tenders and ITT responsesDomestic solar and battery storage are handled by the residential side of the business. The same engineers, a different set of rules, and a different page to start from.
Residential solar PVThe office is in Leeds and most of our work sits within a comfortable drive of it: West, South, North and East Yorkshire, the Humber, Greater Manchester and Lancashire. That is where a survey, a snagging visit and a maintenance call are all straightforward.
Above 50 kWp we travel, because a project that size carries enough survey, design and connection work to justify the distance. If the building sits elsewhere in the United Kingdom, ask. What we will not do is claim a local presence we do not have: outside the north, the honest description is that we come to you.
The details in full
Office visits are by arrangement. It is a working office rather than a showroom, and the useful conversation happens at your site.
