Commercial arrays sized against a year of your half-hourly data, with the grid application, the export limitation and the handover pack handled by us.
The right route depends on whether you want the asset on your balance sheet or the saving in your P and L. We will quote more than one.
You own the array, you keep every unit it makes and every pound it saves, and you take the maintenance with it. The shortest payback of the three and the one most sites choose when the capital is available.

This is the single most useful thing you can send us. It shows when you actually use power, which decides how much of the generation you can consume on site rather than export. Any supplier will provide it for a half-hourly metered site; ask for the HH data for the MPAN.
The value of a self-consumed unit is whatever you are paying for an imported one. Without the current rate the model is guesswork.
Plans speed things up. Where there are none we survey, and for larger roofs that means a measured survey and a structural opinion rather than an estimate from aerial imagery.
This sets what we can connect and whether the application is G98 or G99. It is also what the DNO will ask for first.
Penetrating a roof under warranty can void it. On single-ply and standing-seam roofs there are non-penetrative systems that keep the warranty intact, and we need to know before the design rather than after.
An array sized for today is the wrong size for a site that is about to add a fleet of vans. Tell us the plan and we size for it, or we design in headroom and say what it costs.
Commercial systems almost always need G99 approval from the Distribution Network Operator, which is Electricity North West or SP Energy Networks, depending on where you are, before any installation work starts. The application goes in with the design, and the lead time is measured in weeks, not days.
A constrained part of the network may offer a smaller export capacity than the array could produce, or offer a connection subject to reinforcement works at your cost. Neither is unusual and neither is fatal.
The application, the single line diagram, the inverter compliance certificates and the protection settings. We deal with the DNO correspondence and we tell you the moment a condition appears that changes the design or the price.
We take a year of half-hourly readings and your current import rate and model how much of the generation the site would actually use. That tells us the array size worth building rather than the one the roof would hold. You get the assumptions written down with the numbers.
An engineer goes on the roof, checks the sheet profile, the fixings and the condition, and confirms the access route for plant. Where the loading is close to the limit we get a structural opinion before the design is fixed, because that is cheaper than finding out at installation.
The layout, the string design, the inverter schedule and the single line diagram go together, and the grid application goes in with them. Once the DNO position is known the price is fixed, and it only moves if the scope moves or a connection condition changes the design.
We programme the work around your hours rather than asking you to shut down. Deliveries, plant and roof access are agreed in advance with whoever runs the site, and the electrical tie-in is booked for a window you choose.
We commission with the DNO protection settings in place, set the monitoring up so your own people can see generation and consumption, and hand over the certificates, the as-built drawings and the operating and maintenance information in one pack.
No. The zero rate applies to domestic installations only, so a commercial install is charged at the standard rate. We show the VAT separately on the quote so the capital figure and the recoverable element are both clear.
It depends on the roof area and on how quickly plant can get to the roof. We programme around your operating hours rather than assuming you can shut down, and we give you a week by week plan with the fixed price so you can see what happens on site and when.
Often yes, and the route depends on who holds the lease and who holds the roof. We will talk to the landlord as well as to you, and the funded route tends to suit a tenant because the agreement follows the electricity rather than the asset.
Yes, where there is land and a sensible cable route back to the supply. It sidesteps roof condition and roof warranties entirely, and access for maintenance is easier, so on a site with spare land it is often the better answer.
Asset finance and power purchase agreements are tied to the site rather than to you, so raise it before signing anything. If a move is possible inside the term we will say so and look at the capital route instead.
