Ask any solar installer what the first question on every enquiry is, and it's the same three words: “how much would I save?” If your website can't answer that, the homeowner does what everyone does — closes the tab and asks someone whose site could. A solar savings checker answers it on the spot, and turns the visitor into a lead in the process.
The problem with “get a free quote”
Most solar sites lead with “get a free quote — fill in the form.” That asks a curious, unsure homeowner to commit before they know if solar is even worth it for them. Most won't. They want a number first. Deny them that number and you've handed them to a competitor.
What a savings checker actually does
A SolarCheck tool flips it. The visitor enters their postcode, and in about 30 seconds it estimates their roof's generation and yearly saving — then, while they're looking at a real figure, it captures their name and number.
- It answers the only question that matters, instantly, no phone call.
- It captures a named, pre-qualified lead — someone who's just seen solar could save them money.
- It builds trust — a homeowner who gets a straight answer from your site assumes they'll get straight answers from you.
A quote form asks “will you commit?”. A savings checker says “here's what you'd save” — then asks. One of those converts far better.
Why the data matters
A cheap calculator that just multiplies your bill by a guess looks like a gimmick. A good one uses real data. SolarCheck uses live satellite roof analysis where it's available — the actual roof size and orientation — and falls back to live solar-irradiance data for the postcode everywhere else. So the number is believable, which is exactly what makes the homeowner pick up the phone. The full design comes from your survey; the checker's job is to start the conversation.
Why “custom-built” matters
A generic third-party widget looks bolted on and erodes trust. SolarCheck is custom-built and integrated into your website in your logo, colours and domain — visitors think it's yours, because it is. One good tool, capturing the savings-curious visitors your competitors let walk away. See how it works for solar installers, or how we help solar installers escape the price war more broadly.
