Add-ons

System expansion

Add panels to an existing system when your electricity use grows.

Installer fixing new solar panels beside an existing array on a roof.

More panels for a household or business that now uses more power, checked against your inverter capacity and the Solar ATAP limits.

Who it is for

Owners who have added air-conditioning, an EV, or new equipment since their system went in.

How it works

We review your current system, roof space, inverter, and programme limits, then propose added panels and any inverter change needed.

What to send us

Your current system size, inverter model, installation year, and a recent TNB bill.
