Enter a full Hawaiʻi Island street address for Google’s imagery-derived roof analysis.
Optional — the manual estimator below still works without a satellite scan.
Editable. Default reflects recent Hawaiʻi Island residential pricing.
Planning assumptions: 450 W modules, about 22 sq. ft. per module, and a Hawaiʻi planning production factor before roof orientation and shading adjustments. Final engineering must verify roof geometry, structural conditions, code setbacks, obstructions, utility rules and equipment selection.
2. Preliminary solar potential
A planning estimate — not a construction design.

How this digital estimate works
1. Energy demandYour electric bill and editable utility rate approximate monthly electricity use.
2. Roof capacityRoof dimensions, usable-area percentage, orientation and shading constrain the preliminary panel layout.
3. Google roof analysis + professional verificationFor supported Hawaiʻi Island addresses, Google Solar building insights can add imagery-derived roof geometry and production modeling. Island PV Solutions then verifies setbacks, equipment, structure and field conditions.
