USE THE ESTIMATE WELL

A planning tool—not a roof survey or proposal.

The strongest next step is to replace planning inputs with the homeowner's 12-month usage, measured roof geometry, shade analysis, equipment selection, and confirmed utility terms.

What the model does

Estimates annual production, first-year bill value, long-term savings, and modeled payback using editable assumptions.

What to verify

Roof condition, shade, structural and electrical scope, permitting, interconnection, current utility rates, and tax eligibility.

Planning defaults

The $3.65/W cost and 1,050 kWh/kW production values are editable starting points—not VECOR pricing or guarantees.
