Hawaii solar planning tool
This planning tool gives a rough educational estimate based on electric bill, offset goal, battery preference, and incentive assumptions. It is not a quote. Roof condition, equipment, permitting, electrical upgrades, battery design, financing, and tax eligibility can change the final proposal.
Enter your assumptions
Adjust each input to model the kind of project you are considering. Defaults are intended for Hawaii planning conversations, not final pricing.
Use the result to understand order-of-magnitude cost drivers. Your actual solar proposal may change after reviewing roof condition, shade, electrical upgrades, panel layout, battery configuration, financing, incentives, and utility requirements.

Use these answers to understand what the planning estimate can and cannot tell you before a site-specific proposal.
No. This calculator is an educational planning tool. A real quote requires an electric bill review, roof and electrical assessment, equipment selection, battery design, permitting review, financing discussion, and current incentive review.
Solar pricing, utility rates, production, and incentive treatment vary by project. Editable assumptions let users model different scenarios without pretending there is one universal Hawaii solar price.
The calculator includes simple battery allowances for planning only. Actual battery pricing and value depend on capacity, inverter compatibility, backup loads, electrical work, utility programs, and installation conditions.
It includes an editable tax credit assumption for planning. Tax credit eligibility and value depend on current rules and individual tax circumstances, so customers should consult a qualified tax professional.
The next step is a site-specific estimate that reviews your bill, roof, energy goals, battery needs, financing, and incentive assumptions. That is the only way to create a reliable proposal.
