By the time a commercial buyer actually calls or submits an enquiry, they've usually already narrowed a longer list down to a handful of candidates — based entirely on what they found online. Understanding that research process helps installers make sure they survive it, rather than losing consideration before ever getting the chance to make their case directly.
The Research Sequence, Roughly
A commercial buyer evaluating solar installers typically works through some version of: searching for installers in their area or industry, checking each candidate's website and Google Business Profile, looking for evidence of relevant commercial (not just residential) work, checking reviews and any visible credentials, and often cross-referencing against a directory like ADEO to see how a candidate compares against others. Only after this narrowing does first direct contact usually happen.
What Gets a Business Cut From Consideration Early
- No visible evidence of commercial (versus purely residential) experience
- A website or profile that looks outdated, incomplete, or unmaintained
- No certifications, insurance, or compliance information visible anywhere
- Reviews that are old, sparse, or entirely residential-focused when the buyer needs commercial credibility
- Slow or generic response to an initial enquiry, if one was already sent as a test
As covered in more depth in our piece on building trust before the first call, commercial buyers specifically look for proof points that residential-focused installer marketing often doesn't surface clearly.
The Cross-Referencing Behaviour
Commercial buyers, more than residential ones, often deliberately cross-check a business across multiple sources — company website, Google Business Profile, LinkedIn, a directory listing — looking for consistency and depth of presence rather than relying on a single source. A business that looks thin or inconsistent across these sources reads as higher-risk to a buyer making a significant capital decision, even if the underlying work quality is excellent.
Case Studies Get Read Closely
Unlike a residential homeowner who might skim a testimonial, a commercial buyer evaluating a meaningful investment tends to read case studies more carefully — looking for details that map to their own situation (similar business type, similar system size, similar priorities like load shedding resilience or cost reduction). Generic, detail-free case studies do less work here than a buyer's careful reading deserves.
What This Means Practically
Making commercial credibility genuinely easy to find — not buried, not assumed to be obvious from residential content — matters more than most installers realise, precisely because so much of the buyer's evaluation happens before any direct conversation occurs. By the time you're on the phone, a meaningful part of the decision has often already been shaped by what they found (or didn't find) online.
Where SolarTally and ADEO Fit In
Commercial buyers reaching ADEO — including those arriving after using our solar calculator to get an initial budget sense — are often already deep into this research process, comparing your profile against others on the same page. A complete, commercial-credible profile is doing real work at exactly the moment it matters most.
Frequently Asked Questions
How much of the buying decision is typically made before first contact? It varies, but commercial buyers commonly arrive at first contact with a strong existing impression, sometimes having already ranked their shortlist — meaning the online research phase carries real weight, not just the eventual sales conversation.
Should commercial and residential credibility be presented separately? Where possible, yes — clearly sectioned so a commercial buyer isn't left hunting through residential-focused content to find relevant proof points.
Does LinkedIn presence matter for a solar installer's commercial credibility? It can help, particularly for reaching decision-makers who use LinkedIn for professional research — worth maintaining a basic, current presence there if commercial clients are a meaningful part of your business.
