Generic estimates cost you thousands.

Every solar calculator gives you the same national average. But what your neighbor on the next street actually paid for their 8 kW system is a matter of public record. SunLedger makes that data accessible, so you walk into every quote knowing the real number.

How SunLedger works

01

Get real pricing

Enter your address. We pull building permit data from Honolulu's open data portal and show you what comparable systems in your area actually cost.

02

Compare quotes

Upload quotes from installers. SunLedger benchmarks them against real permit data and other consumer quotes, so you know if you're getting a fair deal.

03

Understand financing

The residential tax credit expired. But third-party ownership still qualifies for 30% ITC. We break down lease, PPA, and loan options for your budget.

Built for how you actually shop for solar

Neighborhood-level pricing

See what homes like yours paid for solar, down to the street level. No more generic state averages.

Module and battery guidance

Not all panels are equal. Compare modules and batteries based on your budget, roof, and energy needs.

🔒

Your data, your terms

We never sell your info without your explicit consent. Request a quote or financing inquiry only when you're ready.

📈

Quote analysis assistant

Upload proposals and get a clear breakdown of what each installer is offering, what's missing, and how they compare.

Tax credit alert

The residential solar tax credit expired. The 30% credit didn't.

The Section 25D credit ended December 31, 2025. But through lease and PPA structures, a commercial entity claims the 30% ITC on your behalf. SunLedger helps you understand which financing path unlocks the credit for your system.

Solar pricing should be transparent.

Hawaii has the highest electricity costs in the nation and the fastest solar payback. The only thing standing between homeowners and a good deal is information. SunLedger puts that information in your hands.
