Buying or Selling a House With Solar and a Battery: What to Check and Hand Over

Checked and updated by our licensed electricians: November 2026

Short answer: Buying: ask for the system size and brands, the installer’s name, the compliance paperwork, the warranty documents and the monitoring app access, and check it is actually producing. Selling: hand all of that over, plus the shut-down procedure, and transfer the app to the new owner. A battery and solar can be a selling point when the paperwork is in order. If you are not sure what you are looking at, an electrician can inspect it.

If you are buying

  • What is it? Panel brand and number, inverter brand and size, battery brand and kWh. The labels on the inverter and battery tell you.
  • Who installed it, and when? The installer’s workmanship warranty may pass to the new owner (ours stays with the property). Product warranties come from the makers.
  • Paperwork: the electrical compliance certificate, the system’s warranty documents, the shut-down procedure and any grid connection details.
  • Is it working? Look at the monitoring app with the seller, or at the inverter display on a sunny day. A system that shows faults or zero production needs checking.
  • Battery position and condition: a compliant, protected position (see where a battery can go), no damage, and a backup reserve set if you want blackout cover.
  • Old or unsafe parts: cracked panels, burnt connectors or water in isolators are red flags. See upgrade, add to or replace an old system.

If you are selling

  • Gather the paperwork above in one folder for the buyer.
  • Note the system details for the listing: size, brands, battery kWh and the age of the system.
  • Transfer or share the monitoring app to the new owner at settlement (owner guides: Sigenergy, GoodWe).
  • Remove your personal settings and any VPP or retailer arrangement in your name, and tell the buyer.

Moving the system to your new house?

Usually not worth it: removal, reinstall and new paperwork cost a lot, and warranties can be affected. It is normally better to leave it and size a new system for the new home.

Questions we get asked

What should I check when buying a house with solar?

The system size and brands, who installed it and when, the compliance certificate and warranty documents, the monitoring app, and whether it is actually producing. Cracked panels or burnt connectors are red flags.

Do solar warranties transfer to a new owner?

Many do, but it depends on the maker and the installer. Our 25-year workmanship warranty stays with the property if the house is sold. Check each product warranty for the exact equipment.

How do I transfer the solar or battery app to the new owner?

Most apps let the owner share or transfer the system to another account. Do it at settlement and remove your personal settings and any VPP or retailer arrangement in your name.

Can I take my solar panels with me when I move?

You can, but it is rarely worth it: removal, reinstall and new paperwork cost a lot and can affect warranties. It is usually better to leave the system and get a new one sized for your new home.

Can you inspect a solar system before I buy a house?

Yes. Our own electricians do solar and battery inspections across the Northern Rivers, including systems installed by other companies.

Are you independently reviewed?

Yes. As well as our Google reviews, homeowners have reviewed us on SolarQuotes, where we’re rated 4.9 from 22 reviews.
