Alectrona
Commercial solar by areaYorkshire-based and quick to your site in Selby, designing commercial solar over 50 kWp for the distribution sheds, rail-freight units and manufacturing roofs across the Vale of York. We have not installed in Selby yet, so we lead with an on-site drone survey and a load-matched design, not a local job count we don't have.
These are representative example reviews, not yet-collected customer feedback. They are written to illustrate the kind of feedback Alectrona aims to earn and are shown as design placeholders while we gather and verify reviews from our first commercial clients. Alectrona is the commercial solar trading brand of RVTC LTD.
What set Alectrona apart was the documented design pack. We had quotes from three installers, but only Alectrona handed us a full set of drawings, a single-line diagram and a design referencing BS 7671 and the G99 connection process. The whole thing read like an engineering submission rather than a sales brochure. Our M&E consultant reviewed it and signed it off without a single query. That gave the board the confidence to release the capital.
Other firms priced our roof off a satellite image and a desktop guess. Alectrona flew an in-house drone survey, fully insured and flown by a qualified commercial drone pilot, and built a 3D model of the actual roof. It picked up plant, vents and a parapet line that a flat aerial photo had completely missed, which changed the panel layout. I would rather find that out at design stage than on the day the scaffold goes up. The accuracy of that survey is the reason I trusted everything that followed.
As a finance director I was wary of being oversold a system bigger than we could use. Alectrona modelled the array against our actual half-hourly consumption data rather than an annual total, so it is sized to what we genuinely draw on site during the day. They were honest that exporting surplus is worth far less than self-consumption, and built the design around that. The capital case stacked up because the engineering was honest, not because the numbers were inflated.
We were undecided between buying outright, leasing and a PPA. Alectrona laid out all three side by side with the pros and cons of each against our balance sheet, instead of pushing the one that pays them best. They were clear about where a PPA makes sense and where capex wins, and pointed us at our own accountant for the tax treatment. The survey and design took a little longer than I expected, but the thoroughness was worth the wait. Genuinely consultative.
The install crew were tidy and well run, and worked to a clear CDM 2015 plan with a proper site induction and RAMS. What impressed me most was the handover. We received a full commissioning pack with the IEC 62446-1 test results, certification, O&M documentation and an as-built record for our maintenance team. As the people who have to live with this asset for the next twenty years, having that paperwork in order matters enormously. Nothing was left loose.
I expected the usual hard sell and got the opposite. After surveying our site Alectrona told us one roof section was not worth covering because of shading, and that a smaller, well-sited array was the better investment than filling every square metre. There was no commission-driven upselling and no pressure. For a six-figure capital project, that straight talk is exactly what you want from the people advising you. We will be using them again on our second site.
Selby is a market town that traded its coal and milling past for energy generation, logistics and manufacturing, and the commercial roofs that came with that shift are large, single-storey and electrically busy through the working day. Alectrona is the commercial arm of RVTC LTD, Yorkshire-based and working across North Yorkshire for rooftop and ground-mount solar above 50 kWp. We reach Selby quickly, from the YO8 town core out to the Sherburn-in-Elmet estates on the LS25 fringe, and we are honest that this is coverage and engineering capability rather than a list of finished local installs.
A system at this scale sits outside the domestic MCS route, which is where the structural loading, the single-line electrical design and the grid connection start to decide whether a roof pays back. That work begins with a measured 3D survey of the actual roof and a PV*SOL model built against your half-hourly load, not a number read off an aerial image. It is the same method whether your unit is a Sherburn distribution shed or an older industrial building off Barlby Road.
Selby's commercial roof stock is dominated by distribution and warehousing, and the road network is why. The Selby bypass on the A63, the A19 and the A1(M) at Junction 42 put the town inside a strong catchment for large-footprint sheds, and that is the building type solar is built for: broad, lightly-shaded roofs over operations running lighting, conveyors, racking and charging fleets through daylight, which is exactly when a south-facing array generates. Sherburn Enterprise Park at Sherburn-in-Elmet, a few miles off Junction 42 of the A1(M) in the LS25 area, is the major logistics and manufacturing hub on this side of the district, a stock of big-box distribution warehouses; the named occupiers there describe the local economy and the kind of roof we design for, not customers of ours. The A19 Business Park near Riccall, built on the former Riccall colliery of the Selby coalfield and redeveloped into a multi-let industrial estate, is the same large-footprint shed profile.
Closer to the town, Selby Business Park off Barlby Road sits a short distance from the bypass and runs trade and distribution units, with established industrial addresses such as Vivars Way off Canal Road nearby. Barlby Road also carries the town's intermodal capability: the Selby Rail Freight Terminal on the former Olympia Mills site gives the area rail-connected distribution, and the wider Olympia Park scheme is redeveloping that ground into a large mixed-use scheme. An animal-feed and agricultural mill has stood on the Barlby Road site since the early 1900s, latterly as Olympia Mills, which is a reminder that the food and agricultural-processing base around Selby is long-standing and still part of the roof stock.
The largest energy presence in the area is Drax, the biomass power station a few miles south of the town near the village of Drax, and we name it as the dominant industrial energy site here rather than as a client. For our work the point of all of this is the load shape underneath the roof. A distribution shed self-consumes a high share of what an array makes because its demand runs through the working day, while a processing or manufacturing unit on a flatter round-the-clock load consumes even more on site. We model each building on its own half-hourly data rather than assume a single Selby template.
Every Selby design starts with an on-site survey rather than a satellite guess. Our in-house drone pilot, fully insured and qualified to A2 CofC and GVC standard, flies a 3D survey of the roof to capture the real surface: pitch, orientation, parapets, plant, rooflights, shading and the true usable area. That model feeds a PV*SOL simulation run against your half-hourly load, so the array is sized to what the building actually uses rather than to its floor area.
The survey travels to Selby exactly as it does anywhere in Yorkshire. Whether the roof is a Sherburn Enterprise Park distribution shed, a rail-freight unit off Barlby Road or an older industrial building in the YO8 core, the pilot comes to you and the design is built from what the drone records on the day.
The distribution network operator for Selby is Northern Powergrid, and any system over 50 kWp connects under a G99 application to them. Selby is one to plan the connection on early, and for a specific reason worth raising honestly. The Selby A grid supply point, linked to the Drax connection, is reported as one of the more constrained supply points in Yorkshire, which means larger schemes in the area may carry Active Network Management or curtailment conditions. We flag that as an indicative consideration rather than a settled fact for your postcode: it comes from market reporting, not Northern Powergrid's own published figures, so we confirm the actual position with a current connection enquiry for your site before designing to it.
That constraint, where it applies, is not a reason to install less. A high self-consumption design keeps most of the generation behind the meter on a Selby distribution or process roof, which eases the export side of the G99 position and protects the case against any curtailment terms. Where export needs limiting we design to it from the start, including export-limitation engineering and, where it improves the case, battery storage to hold surplus on site rather than push it to a busy grid. We prepare and manage the G99 application and the network correspondence as part of the project.
The older estates around Selby and Sherburn-in-Elmet carry a real number of commercial arrays from the Feed-in Tariff years, much of it now well into its working life, often with no single party clearly accountable for it after the original installer moved on. Through our sister operation Solar Tech Support we offer independent, brand-agnostic operation and maintenance, and we take over those older systems whoever fitted them and whatever the panels and inverters are. That covers performance monitoring, fault-finding, inverter and string work, cleaning on these large flat roofs and a clear read on whether an array is still earning what it should.
We will not publish a fixed response-time promise we cannot stand behind for Selby specifically. What we will do is assess the existing system on site, tell you honestly what it is producing against what it should, and agree a maintenance scope that fits the asset and the site, whether that is one ageing array on a Barlby Road unit or several across the Sherburn estates.

Not yet, and we say so plainly. We are Yorkshire-based and cover Selby and the wider Vale of York for commercial solar over 50 kWp, but we make no claim of a local track record we have not earned. What we bring is the engineering a system this size needs: an in-house drone survey of your roof, a PV*SOL model built against your own half-hourly load, a design to BS 7671 and a G99 connection to Northern Powergrid.
The large distribution and warehousing sheds around Sherburn Enterprise Park, the A19 Business Park and Selby Business Park, the rail-freight and industrial units off Barlby Road, and the processing and manufacturing buildings across the area. These carry steady daytime demand, which lets a well-sized array be consumed on site rather than exported. We model each building on its own half-hourly data rather than assume a single template.
It may be. Northern Powergrid is the network operator, and the Selby A grid supply point, linked to the Drax connection, is reported as one of the more constrained in Yorkshire, so larger schemes can carry Active Network Management or curtailment conditions. We treat that as indicative rather than settled fact, because it comes from market reporting and not Northern Powergrid's published figures, and we confirm the actual position with a G99 connection enquiry for your site before designing to it.
Yes. Through our sister operation Solar Tech Support we provide independent, brand-agnostic operation and maintenance and take over older systems, including Feed-in Tariff-era arrays on the estates around Selby and Sherburn-in-Elmet whose original installer has moved on. We assess the system on site first and agree the scope against what we find, rather than quoting a fixed promise sight unseen.
The honest answer is that the figure comes from the survey and the PV*SOL model, not a per-mile rate or a from-price we could quote before seeing the roof. A system over 50 kWp on a Sherburn distribution shed prices differently from one on an older industrial unit off Barlby Road, because the cost is driven by the roof structure, the panel and inverter specification, the electrical and grid-connection work and whether storage earns its place against your load. Our approach is the same wherever you are in Yorkshire: an in-house drone survey of the actual roof, then a model built against your half-hourly consumption, and the cost falls out of that engineered design rather than a headline rate. We would rather give you a number we can stand behind after the survey than a cheap one we cannot.
We are Yorkshire-based, so the survey comes to you and a site visit in Selby is straightforward to arrange, from the YO8 town core out to the Sherburn-in-Elmet estates on the LS25 fringe. Travel is not the long pole on the programme. What sets the timeline is the G99 connection with Northern Powergrid, and Selby is one to start early, because the Selby A grid supply point linked to the Drax connection is reported as one of the more constrained in Yorkshire and a larger scheme there may carry Active Network Management or curtailment conditions that the connection enquiry needs to confirm. Survey, PV*SOL design and a costed proposal move quickly once we have access to the roof and your half-hourly data; it is the network response, not the drive over, that governs when the array can be energised.
Wherever you are in the region, the on-site drone survey comes to you and the PV*SOL model sets the figure. Send us the site and the half-hourly load, and we will come back with a designed system.
