Solar growth math, run in your browser.
Four calculators built from the same published numbers cited throughout our solar pages: Wood Mackenzie's 2026 CAC forecast, SunVoy's lead-source conversion data, Enervio's pipeline formula, aged and exclusive lead pricing, and IntegrateSun's dealer fee analysis. No signup, no email gate, and every source is linked at the bottom of each tool.

Each calculator runs entirely client-side. Your inputs never leave your browser, and every default links to the source it came from.
Customer Acquisition Cost (CAC) Calculator
Turn your monthly spend, installs, and system size into a cost per install and a cost per watt, then compare it against a pay-per-sit appointment model at $249 flat.
- ✓Benchmarked against Wood Mackenzie's 2025-2026 CAC data
- ✓Converts CAC into the cost-per-watt figure the industry tracks
- ✓Compares your CAC to VA Horizon's flat appointment rate
No signup. Live client-side math.
Setter Pipeline Calculator
Set a monthly install goal and work backward to appointments needed, leads needed at your lead-to-appointment and appointment-to-sale rates, a weekly booking target, and a monthly budget.
- ✓Uses Enervio's published leads-per-sale formula
- ✓Defaults to SunVoy's sourced phone-lead conversion rates
- ✓Turns an install goal into a weekly appointment target
No signup. Live client-side math.
Cost Per Install Calculator
Compare aged leads, exclusive leads, and VA Horizon appointments on real cost per installed system, using sourced pricing and close-rate bands for each preset.
- ✓Aged Lead Store and Invention Solar aged-lead pricing tiers
- ✓Separates show rate from close rate for an honest comparison
- ✓Will not always show VA Horizon as the cheapest option
No signup. Live client-side math.
Dealer Fee Calculator
See the dollar amount a solar loan's dealer fee actually embeds, the effective system cost without it, and how many direct appointments that money could buy instead.
- ✓IntegrateSun-sourced 22% average dealer fee default
- ✓Breaks out embedded fee dollars from the physical system cost
- ✓Compares the fee against a direct appointment purchase

Efficiency math for a contracting market.
Residential solar installs are forecast to decline 18 to 21% in 2026, and Wood Mackenzie found customer acquisition cost is set to spike 40%, from a five-year low of $0.60 per watt in 2025 to a forecast $0.84 per watt in 2026, as the federal tax credit expiration pulls demand forward and then fades. Dealer-network installers are the most exposed to that squeeze, since embedded loan dealer fees average around 22% and fund a commission stack that scales with every deal, whether the market is growing or not.
None of that math argues for spending more to chase a shrinking pool of buyers. It argues for knowing your real cost per install, per watt, and per appointment down to the decimal, so every dollar you do spend is doing measurable work. These four calculators put the same sourced numbers behind our solar pages into tools you can run with your own figures instead of ours.
These tools are not built to produce a predetermined answer. The cost per install calculator will sometimes show a cheap aged lead costing less on paper than a $249 booked appointment, depending on the show rate and close rate you set. That is intentional. Every output is labeled as an estimate from your inputs, not a guarantee.
