Alectrona
Commercial solar by areaAlectrona is Yorkshire-based and quick to reach Sheffield for commercial solar over 50 kWp. We have not yet installed in the city, so we lead with what we can show you: an in-house drone survey of your roof and a PV*SOL design built against your own half-hourly load.
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.
Alectrona is the commercial arm of RVTC LTD, working UK-wide on rooftop and ground-mount solar above 50 kWp. We are based in South Yorkshire, so Sheffield sits inside easy reach for a site visit rather than a long haul. We are honest about one thing up front: we hold no completed installs in the city yet, so this page is about coverage, the engineering a system of this size demands, and the on-site survey we run before any design is drawn.
A system over 50 kWp falls outside the domestic schemes and carries real structural, electrical and grid-connection weight. That is why every Sheffield enquiry starts with an insured drone pilot flying a 3D survey of the roof, a PV*SOL model built against your half-hourly consumption, and a design to BS 7671. The aim is a system sized to what your building actually uses through the working day rather than a number pulled from a roof area.
Sheffield's commercial roof stock is unusually well suited to self-consumption, because so much of it sits on energy-intensive industry. The Don Valley corridor through Tinsley and Attercliffe carries the largest concentration of advanced manufacturing and steel outside the Midlands, the kind of stainless, forging and heavy-engineering plants the city is known for. These are continuous-process buildings with a flat, high daytime baseload, which is the load shape solar serves best: most of what the array generates is consumed on site at the meter rather than exported, so the economics lean on avoided import rather than export tariffs.
On the Rotherham border, the Advanced Manufacturing Park gathers research and production halls of the sort occupied by aerospace and automotive engineering and the university's AMRC, large flat-roof structures with steady technical loads. North-east of the centre, Meadowhall and the retail parks around it form one of the densest runs of flat-roof retail in England, and Sheffield Business Park carries 160-plus occupiers across big single-storey commercial and R&D units. Different roofs, different load profiles, but the same logic: a system designed around the building's real demand curve, modelled in PV*SOL before anyone quotes a figure.
The mix matters for the design as much as for the sizing. A forging plant in the S9 postcode and a retail unit at Meadowhall want very different inverter strategies, mounting approaches and export-management settings, and we work those out from the survey and the half-hourly data rather than a template.
The on-site survey travels to Sheffield exactly as it does anywhere we work. Our in-house drone pilot, A2 CofC and GVC qualified and insured, flies a 3D survey of your roof so the design starts from accurate geometry, shading and condition rather than a satellite guess. That model feeds the PV*SOL simulation against your half-hourly load, and the result is a system designed to BS 7671 and sized to your building. Sheffield is a short trip from our South Yorkshire base, so booking a survey here is straightforward.
The distribution network operator across Sheffield is Northern Powergrid, and any system this size connects under a G99 application to them before it energises. The Don Valley carries a genuine advantage here. The legacy heavy-industrial grid laid down for steel and engineering means the low-voltage and high-voltage capacity around Tinsley, Attercliffe and the S9 corridor is often more generous than the constrained residential primaries elsewhere in the city. That can shorten the connection conversation for a larger array, though it is never assumed: we check the specific point of connection and frame the G99 application, and where headroom is tight or export needs limiting we design around it with on-site export management rather than promising capacity we have not confirmed.
Sheffield has a deep base of FiT-era commercial solar, much of it installed on steel-industry and manufacturing buildings between 2012 and 2016. A lot of those arrays are now running on ageing inverters with little or no monitoring, quietly losing yield that the owner never sees. Through Solar Tech Support we take on independent operation and maintenance and the takeover of older systems regardless of who installed them or which brand sits on the roof. That means inverter checks and replacement, fault-finding, monitoring brought up to date and performance restored.
We do not publish fixed service levels we cannot stand behind. The honest starting point is a site assessment of the existing system, a clear picture of what it is producing against what it should, and a maintenance plan scoped to that, whether you have one ageing array or a portfolio across the Don Valley.
Sheffield's commercial roof stock is not only heavy industry. The city carries one of the larger public and institutional property estates in the North, and those buildings own their roofs for the long term, which is exactly the ownership profile a twenty-year asset suits. Two universities, the University of Sheffield and Sheffield Hallam, run substantial campus estates across the city centre and the S1 and S10 districts, with teaching blocks, laboratories and student accommodation carrying steady weekday and term-time demand. The acute NHS estate is significant too, anchored by the major teaching hospitals to the west of the centre, where heating, ventilation and clinical plant draw a continuous load that a rooftop array offsets behind the meter.
Add the local authority's own estate, the leisure centres, depots and operational buildings, and there is a deep run of institutional flat and low-pitch roof that sits outside the Tinsley and Attercliffe manufacturing belt this page leads on. These are the kinds of organisation for which a system over 50 kWp is a planned capital decision against a published carbon target rather than an opportunistic add-on. Our work on any of them starts the same way: a drone site survey and a PV*SOL model against the building's half-hourly load, then a design to BS 7671. For these sectors the relevant cluster is public-sector and council estates, where procurement, programme and connection all run to their own rhythm.
For a rooftop array on an existing commercial building, the planning position in Sheffield is usually straightforward, because solar on a roof generally falls under permitted development rather than a full application. That changes where the building is listed, sits in one of the city's conservation areas, such as those around the historic centre and Kelham Island, or where a ground-mount scheme is proposed on open land. Sheffield is unusually green for a major city, with a large share of its area inside the Peak District National Park boundary to the west and a substantial green belt, so a ground-mount enquiry on the rural fringe carries a real planning dimension that a Don Valley rooftop does not.
The local planning authority is Sheffield City Council, and the policy framework is set by the city's emerging Local Plan, which guides where development and land use sit across the district. We are not a planning consultancy and we say so plainly, but the survey and design stage is where these questions surface, so we flag them early rather than late. Where a scheme needs a planning route or a structural sign-off, that becomes part of the programme alongside the G99 connection. The honest sequence is the same one we run everywhere: survey the roof, model the load, confirm the grid position with Northern Powergrid, and only then commit to a design. Our commercial process sets out each of those stages in order.

No. We are honest that we have not yet completed an installation in Sheffield, so we do not claim a local track record. What we offer is full coverage of the city for systems over 50 kWp, an in-house drone survey of your roof, and a PV*SOL design built against your own half-hourly consumption and to BS 7671.
We are Yorkshire-based, in South Yorkshire, which puts Sheffield within easy reach for a site visit. We are not claiming a Sheffield office. The advantage is simply that our surveyor and drone pilot can get to your roof quickly rather than travelling a long distance.
Northern Powergrid is the distribution network operator for Sheffield, and a system over 50 kWp connects under a G99 application to them. The Don Valley's legacy heavy-industrial grid often gives better low-voltage and high-voltage headroom than constrained residential areas, though we confirm capacity at your specific connection point rather than assuming it.
Yes. Sheffield has many FiT-era arrays from 2012 to 2016 on manufacturing and steel-industry roofs, often with ageing inverters and no monitoring. Through Solar Tech Support we provide independent, brand-agnostic operation and maintenance and take over older systems, starting with a site assessment of what the array is producing against what it should.
We do not quote a per-kWp or from-price for Sheffield, because a system over 50 kWp is sized to your building rather than priced off a rate card. The figure comes from the survey and the PV*SOL model rather than a per-mile charge or a headline number. What sets the cost is your roof area and structure, the array size your half-hourly load actually justifies, the inverter and any export-limitation or battery, and the G99 connection works. We carry out the drone survey and produce that costed design before you commit to anything, so the number you see reflects your own building and load, whether it is a Don Valley manufacturing roof or a city-centre institutional estate.
Quickly. We are based in South Yorkshire, so a Sheffield survey is a short run rather than a long haul, and booking a drone survey of your roof is straightforward. The wider programme, though, is set mainly by the G99 connection process with Northern Powergrid rather than travel time. Once the survey and PV*SOL design are agreed, the connection application and any approval are usually the longest lead item, and for a larger array that is the part we resolve early. We will give you an honest timeline for your specific site rather than a fixed promise, because the connection position drives the schedule more than anything we control.
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.
