The biggest leak in solar lead generation isn't lead volume. It's follow-up. Here's a simple system built around QR scan alerts and your CRM.
Most solar installers don't have a lead problem. They have a follow-up problem.
A homeowner enquires. Someone calls once, gets voicemail, sends an email that lands in Promotions, and moves on to the next job. The quote sits in the CRM marked "sent". Three weeks later the homeowner signs with whoever called back.
You paid to generate that lead. Someone else got the install.
Where solar leads leak
- Slow first contact. The longer the gap between enquiry and call, the cooler the homeowner gets and the more competitors they've spoken to.
- One attempt, then nothing. Unknown numbers go unanswered and inboxes are crowded. One call and one email isn't a follow-up process.
- Quotes that go quiet. Solar decisions involve partners, finance and rebates. A quote with no follow-up for 7–14 days is usually a lost quote.
- No signal of who's actually interested. Sales teams chase everyone equally, so the hottest prospects wait in the same queue as the coldest.
Fewer leads to chase, because they're the right ones
Follow-up gets easier when every lead is someone who can actually buy. Stash Direct Mail generates your target database (or you can use your own prospect list), so your sales team only spends time on:
- Homeowners, not tenants
- Houses, not apartments
- Properties without solar for system sales, or with solar for battery sales
And we can prioritise homeowners at a buying moment: new movers into homes without solar, owners of systems over 10 years old, and recently storm-affected areas.
Start with a better signal: the QR scan alert
Every Stash Direct Mail letter carries a QR code unique to that household. When a homeowner scans it, we notify you with the property address.
That changes the follow-up conversation. Your team isn't working a cold list. They're following up an address where, in the last day, someone picked up your letter and scanned it. If that address is already in your CRM, call with context: "You scanned our letter about the battery rebate. Happy to answer any questions?" If it isn't, a door-knock or a second letter with a stronger offer is the fastest next step.
A follow-up workflow that runs every time
Plug scan alerts into whatever CRM or sales process you already use:
| Trigger | Action | Timing |
|---|---|---|
| QR scan alert received (property address) | Match the address against your CRM and prospect lists; assign to a salesperson | Same day |
| Address already in your CRM | Call, then SMS if no answer, using the contact details you hold | Within 24 hours |
| New address, no contact details | Door-knock, or send a follow-up letter with a stronger offer and a new QR code | Within 48 hours |
| Homeowner enquires but doesn't book | Email with the same offer as the letter | Day 3–5 |
| Quote sent, no reply | Check-in call | Day 7 |
| Quote still quiet | Follow-up letter: a personalised reminder of the quote and offer | Day 14 |
| Lost or "not now" | Add to a long-term letter cadence | Every 6–8 weeks |
Why a letter at day 14? Because by then the homeowner has stopped answering calls and is skimming emails. A personalised letter on the kitchen bench is the touch that cuts through, and with its own QR code you'll know if it reopened the conversation.
One service, done for you
Stash Direct Mail runs the whole loop:
- We generate the database, or load yours: past enquiries, stalled quotes, and existing solar customers without a battery.
- We send your letter, personalised to each homeowner, through our mail house.
- We track conversion with a unique QR code per household and send you a scan alert, which kicks off the workflow above.
With batteries now being installed at 153 for every 100 new solar systems (Clean Energy Council, Jan–Jun 2026), solar owners are a list in their own right. Owners whose systems are over 10 years old are the strongest of them: due for an upgrade, and usually without storage.
The bottom line
The cheapest solar lead is the one you already paid for, and the easiest to close is one that was qualified before it reached you. Stash Direct Mail builds the list, mails your letter and alerts you to every scanned address. Your CRM workflow makes sure nobody's missed, and a follow-up letter catches the quotes that went quiet.
