Solar Sales Close Rate: What the Data Actually Shows

Quick answer

One industry source, AgentZap, puts average solar sales close rate at 8% to 12%, with top performers above 15%. That is a single-source, moderate-confidence figure, not an audited industry benchmark, and should be treated as directional. The more granular, separately sourced numbers come from SunVoy: referral leads book about 80% of the time and close about 37.5% of booked appointments, a 29.2% net close rate, while phone leads book about 71% of the time and close about 25%, a 17.75% net rate.

The Headline Number, and Why It Deserves a Caveat

Search "solar sales close rate" and one figure comes up repeatedly: 8% to 12% average, with top performers exceeding 15%, cited by AgentZap (AgentZap). This research found that number from a single source, with no independent second dataset to corroborate it. That does not make it wrong, but it means the honest way to use it is as a directional reference point, not a number to build a sales forecast around without also tracking your own team's numbers.

The More Useful Numbers: Close Rate by Lead Source

A second, separately sourced dataset from SunVoy breaks close rate down by where the lead actually came from, which is more actionable than any single blended average. Referral leads book roughly 80% of the time and close roughly 37.5% of booked appointments, a 29.2% net close rate. Phone leads book roughly 71% of the time and close roughly 25%, a 17.75% net rate (SunVoy). The gap between those two net rates, nearly 12 percentage points, is a bigger lever than most script or training changes could realistically produce.

Why Source Explains More Than Any Single Average

A company blending referral leads, phone leads, and other channels into one close-rate number hides exactly the gap SunVoy's data shows. The same logic that applies in roofing applies here: track close rate by source, not as one blended figure, before deciding which channel deserves more investment. A team running a 20% blended close rate could be closing nearly 30% of its referral leads and under 18% of its phone leads, and neither number is visible until the sources are separated.

What Actually Moves the Number in a Contracting Market

With residential installs forecast to contract 18% to 21% in 2026 (SEIA) and third-party ownership expected to reach 65% of reps' books, an appointment that can convert regardless of financing path matters more than raw volume. A close-rate strategy built only around cash and loan buyers is fighting the market's direction rather than the appointment's quality.

Lead source	Book rate	Close rate	Net close rate
Referral	~80%	~37.5%	~29.2%
Phone	~71%	~25%	~17.75%

Source: SunVoy. Net close rate is book rate multiplied by close rate, as reported. Compare against the separately sourced, single-source AgentZap benchmark of 8% to 12% average, 15%+ for top performers, treated here as directional, not audited.

FAQ

What is a good close rate for solar sales?

One source, AgentZap, cites 8% to 12% average, with top performers above 15%, but that is a single-source figure and should be treated as directional. More reliable is tracking your own close rate by lead source, since SunVoy's data shows referral and phone leads convert at very different rates.

Do referral leads close better than phone leads in solar?

Yes, by a wide margin according to SunVoy. Referral leads net a 29.2% close rate (80% book rate, 37.5% close rate) versus 17.75% for phone leads (71% book rate, 25% close rate).

Is the 8% to 12% solar close rate figure reliable?

It is a single-source figure from AgentZap, with no independently corroborating dataset found in this research. Use it as a rough directional reference, not an audited industry benchmark, and prioritize tracking your own numbers by lead source instead.

How should a solar company track close rate?

By lead or appointment source, not as one blended number. A single average hides which channels are actually performing, the same gap SunVoy's referral-versus-phone data makes visible.
