Alectrona
Commercial solar panels · over 50 kWp · outside MCSJinkoSolar commercial solar panels come from a China-headquartered module maker with Silicon Module Super League heritage (2015 to 2019). It is a BloombergNEF Tier 1 manufacturer (Q1 2026); we re-verify the live quarter for the exact module before contract.
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.
One of the highest-shipping module makers in the world and a historical Silicon Module Super League member (PV-Tech, founding member 2015). It is on the BloombergNEF Tier 1 list as of Q1 2026 and holds a PV ModuleTech AA bankability rating, and is a 2026 Kiwa PVEL Top Performer. We are precise here: JinkoSolar was removed from the BNEF Tier 1 list in Q2 2024 over a minor unresolved legal matter and subsequently reinstated, so we describe its current Q1 2026 listing rather than an unbroken record.
JinkoSolar earns a place on a commercial roof as a high-volume mainstream module, so it usually sits in the value part of our bankable line-up rather than the premium end. On larger, simpler arrays, where the limit is budget and roof area is not tight, that pricing position lets the panel count and the balance-of-system work without compromise. We treat its bankability honestly. It is on the BloombergNEF Tier 1 list as of Q1 2026, a financing track-record signal lenders and funders look for on schemes above 50 kWp, and that is a measure of financeability rather than how a module performs in the field. Because the list is quarterly and JinkoSolar was removed in Q2 2024 and later reinstated, we describe its current Q1 2026 listing and re-verify the live quarter for the exact module before contract instead of claiming an unbroken record.
The choice is never a brand decision made in advance. We fly the roof, build the design in PV*SOL, and match the module to the geometry, the structural loading and your generation target. Where JinkoSolar fits the case, we name its scheme, grade and quarter; where a constrained roof needs a higher-efficiency module, we say so. See how we read Tier 1 and bankability.
JinkoSolar reaches the UK commercial market mainly through its mainstream n-type TOPCon range, the cell technology that now leads most large-format module lines. TOPCon places a thin tunnel-oxide passivating layer behind the cell, which lifts efficiency over older p-type PERC and gives a flatter temperature coefficient, so output holds up better on a warm summer roof and a higher bifacial gain is available on reflective commercial surfaces. For larger arrays, the practical effect is steadier real-world yield against the datasheet model and a long linear-output curve over the asset life.
We do not lead JinkoSolar with a single flagship SKU on this page, and we do not hold its module specifications in our registry, so we will not quote a wattage, an efficiency percentage or a dimension figure we cannot stand behind. The exact module, its cell technology, nameplate power, efficiency and physical size are confirmed against the current manufacturer datasheet for the SKU specified for your roof, then set out in your written proposal. That keeps roof-fit honest. The module we model in PV*SOL, size the mounting and structural loading around, and order is the same module documented in the specification. If you want the technology comparison in full, see TOPCon vs HJT vs PERC.
Warranty terms are not held in our brand registry, and product and performance cover varies by JinkoSolar series and revision, so we will not quote a figure here. We confirm the exact product warranty years, the linear performance warranty and the claims route against the manufacturer datasheet for the specific module specified for your roof, then set them out in writing in your proposal, so the cover you rely on matches the panel actually installed. Behind that warranty sits a maker that is a BloombergNEF Tier 1 manufacturer as of Q1 2026 and holds a PV ModuleTech AA bankability rating, with a 2026 Kiwa PVEL Top Performer result naming its measured field reliability alongside that financeability evidence.
A commercial array above 50 kWp sits outside the domestic MCS scheme, so assurance comes from the engineering rather than a badge. We design and certify to BS 7671, commission and test to IEC 62446-1, run the G99 application with the DNO, work to CDM 2015 duties throughout, and base the array on a structural survey of the roof. RVTC LTD holds the contract and the responsibility. The route to quality without MCS is explained in our quality without MCS guide.
MCS does not cover systems this size, so the rigour is what you rely on instead. These are the component-level standards we hold on every install, at commercial scale.
MC4 plug-and-socket connectors are one of the most common failure points in the UK installed base, and the field-made ones are where the risk lives. Every connector we crimp on site gets a sealed ArcBox enclosure: weatherproof, UV-stable, and proof against the arcing-on-corroded-pins failure behind many rooftop PV fires. Diagnosed in real time through our sister company, Solar Tech Support.
A commercial array is a large metal structure on an exposed roof, wired straight into your distribution board. We earth and bond every array to BS 7671 and fit the surge protection that stands between a lightning transient or a grid spike and your inverters and switchgear. It protects the asset and the building it feeds, and it is built into the base design on every install.
Our Qualifying Supervisor, a fully AM2-trained electrician, personally reviews the install report on every job before commissioning sign-off: photos, test certificates, torque-check log and commissioning data, all filed and checked. We are an engineering company first, so the installer never signs themselves off.
