Eligible Project Cost ($)

A key variable in determining your solar investment tax credit (itc) estimate.

Marginal Tax Rate

Ranges from "21% Corporate Rate" to "37% Top Individual Rate." Choosing 37% Top Individual Rate can cost 1.8x more than 21% Corporate Rate.

Scenario Complexity

Ranges from "Basic / Standard" to "Advanced / Complex." Choosing Advanced / Complex can cost 1.5x more than Basic / Standard.

Company Size & Scope

Enterprise pricing often differs significantly from SMB pricing. Vendor volume discounts, implementation complexity, and support tiers all scale with company size.
