The system’s figures, before you sign.
Watts per square metre worked out from the dimensions, kits by kW, and the annual yield multiplied from the figure we write, with its source beside it.
The film runs without sound and stays still if you have turned on reduced motion in your system.
Panels, inverters and batteries
Three ways to have it fitted
The same rows on every option: what is included, what is not, who is responsible.
| The kit only | Kit and installationMost chosen | Turnkey | |
|---|---|---|---|
| Who it is for | Anyone with an electrician | Houses with a simple roof | Anyone who wants no hassle |
| What the price includes | Panels, inverter, mounting, cabling | The kit plus labour and commissioning | Everything, including the grid connection file |
| Who installs it | You, with your electrician | Our own crew | Our own crew |
| Who handles the permits | You | You, with the documents from us | Us |
| Workmanship warranty | The product warranties | The product warranties plus the workmanship one | The product warranties plus the workmanship one |
Installation prices are quoted after we see the roof, not from a table.
By part of the system
From the energy bill to commissioning
What happens, in order, and how long each step takes.
-
You send a bill and a photo of the roof 5 minutes
The bill shows the annual consumption, the photo the orientation and the shading. Without them, any yield figure is a guess.
-
You get the sizing 2 working days
How many kWp, how many panels, which inverter and what yield comes out at your area’s figure — with the source written in the report.
-
You confirm the kit
The order goes through like any other in the shop, with an invoice and the warranties in order.
-
The installation 1–2 days per house
Mounting, panels, inverter and the board. The roof is left closed as it was found.
-
Commissioning and the paperwork on the grid operator’s schedule
The checks, the inverter settings, then the documents for the connection. The timings here are not ours.
The durations are from our projects so far; the connection file depends on the grid operator, not on us.
A multiplication written in the open, not a promise
Annual yield is not guessed: the system size is multiplied by the area’s yield per kWp. We write that figure with its source beside it, and where the source is missing we show no figure at all.
A south-facing roof and an east-facing one, with the same kit, give different yields. So do two neighbours, if one has a walnut tree in the yard.
The kit, the installation, the commissioning and the connection file. What is not up to us — the grid operator’s timings — is stated separately, so it does not read as a promise.
A full spec sheet
Wp, efficiency, voltage.
Watts per square metre
Worked out from the dimensions.
Two warranties, stated separately
Product and performance.
Sizing from your own bill
Not from what fits on the roof.
Questions before the installation
What people ask us most often on the phone.
How many kW do I need?
Why will you not tell me the yield right away?
What is the difference between the product and performance warranties?
Does any battery work with any inverter?
