How We Work

We ask for your bill before we look at your roof

Most solar quotes begin with how many panels fit. That produces a number quickly and it answers the wrong question. What decides whether a system pays for itself is how much of its output you use yourself, and that is a fact about your household, not your roof.

So the first thing we want is your annual kWh figure, and ideally half-hourly data from your smart meter. It costs you five minutes and it is the difference between a system that fits and a system that was in stock.

We measure shading rather than guessing it

One shaded panel can drag down everything wired in series with it, and shade moves through the day and through the year. We survey it properly, plan the strings around it, and fit optimisers where they genuinely earn their keep instead of adding them to every quote as a matter of course.

The quote is the price

Fixed in writing before any work begins, after a free on-site survey. Panels, inverter, battery, mounting, scaffolding, electrical work and the network operator application, all itemised. Nothing added afterwards.

We model honestly

Generation is modelled using the standard MCS methodology against your actual roof. Battery performance is modelled on realistic round-trip efficiency and usable capacity, not nameplate figures. Payback comes as a range with its assumptions attached, so you can interrogate it — and use the same questions on anyone else’s quote.

If the numbers do not work, we will say so before a survey rather than after one.

We handle the network operator and the certification

G98 notification or G99 approval, submitted by us, with the response time built into the programme. MCS registration on completion, because you need it to claim an export tariff. Electrical certification to the current wiring regulations. You get the whole file at handover.

We tell you about the roof

Panels are up there for twenty-five years or more. If the covering underneath has a few years left in it, you should hear that before we fix rails to it, not after. It is an awkward conversation that saves an expensive one later.

Part of a group, which occasionally matters

ZenithNord is one of five specialist businesses. If solar is not the right first move — because the heating is the real problem, or because the site is commercial or industrial scale — there is a team in the group who does that properly, and we would rather point you at them than sell you something that half fits.

• ArcticNord — air conditioning and air-to-air systems.
• EmberNord — boilers and heating.
• AuraNord — air source heat pumps.
• SOLARFIELD — commercial and industrial solar at scale.

Send us your annual kWh figure and a photo of the roof and we will tell you what is realistic before anyone visits.
