A great solar offer at the wrong moment gets binned. Here are the trigger moments that make homeowners ready to act, and how to be in the letterbox when they happen.
The same letter can be ignored in March and acted on in June. Nothing about the offer changed. The homeowner's situation did.
Most solar marketing goes out when the installer has time or budget, not when the homeowner is ready. Timing the letter to the moment of need is one of the cheapest ways to lift response.
The trigger moments that move solar buyers
The three triggers Stash Direct Mail targets for you:
| Trigger | Why it works | What the letter should say |
|---|---|---|
| Just moved in, no solar | New owners are setting up bills and planning upgrades for the home | "Start life in your new home on lower power bills" |
| Panels over 10 years old | Older systems produce less and rarely have a battery | An upgrade and storage offer: more output, store what you generate |
| Recently storm-affected area | Roofs are being repaired or replaced | "If your roof's being fixed, it's the best time to add solar" |
Other moments worth adding to your calendar:
| Trigger | Why it works | What the letter should say |
|---|---|---|
| Bill shock (after peak summer and winter quarters) | The pain is fresh and has a dollar figure on it | "Your last bill doesn't have to be your next one" |
| Rebate step-downs | The battery discount under the Cheaper Home Batteries Program reduces on a set schedule | A clear, honest deadline: book before the next reduction |
| Website enquiry or quote gone quiet | They've shown intent but didn't book | Personalised follow-up on what they asked about |

Timing on top of tight targeting
Every trigger list is still filtered the Stash Direct Mail way: homeowners only (no tenants), houses only (no apartments), and no solar for system offers or existing solar for battery offers. And it's done for you: we generate the list (or you can use your own prospect list), send your letter, and track every response with a unique QR code.
Why letters are faster than you think
The old knock on mail was that it was slow. But once letter production is automated, a follow-up letter can be generated from your existing template and sent within days of the trigger, not weeks. For a decision that takes most homeowners several weeks anyway, that's well inside the window.
Following up website enquiries, the privacy-safe way
Some US direct mail firms match anonymous website visitors to home addresses and mail them automatically. In Australia that approach raises real privacy questions, and it isn't something we recommend.
There's a simpler, safer version that works just as well for installers:
- Capture the address on your site. A savings calculator or roof assessment form that asks for the address in exchange for a personalised estimate.
- Load those enquiries into Stash Direct Mail as your own database.
- Send a tracked letter to anyone who didn't book, referencing what they asked about.
- Get a scan alert when they engage, and follow up while they're warm, using the contact details they gave you with the enquiry.
The homeowner gave you their address. A letter that follows up on their own enquiry feels like service, not surveillance.

Build a trigger calendar
Put the predictable triggers in the diary so letters go out on time, every time:
- Ongoing, monthly: new movers into homes without solar.
- Ongoing, quarterly: owners whose systems have passed 10 years.
- As events happen: streets in recently storm-affected areas.
- Seasonal: after the January–February and July–August bill cycles.
- Policy: in the weeks before each scheduled battery rebate reduction.
- Weekly: new enquiries that didn't book, quotes quiet for 14 days.
The bottom line
You can't make a homeowner ready. You can make sure your letter is in their hand when they are. Stash Direct Mail finds them at the moments that matter (new move, ageing system, storm damage), mails your letter, and alerts you to the address of every scan.
