Equipment alternates that clear IE review
Alternates screened for real equivalence
Substitute equipment gets evaluated against the original spec's actual performance and durability characteristics, not just a similar price point, before it's proposed as a value-engineered option.
Vetted against IE review standards
Alternates get checked against the criteria an independent engineer typically applies during bankability review, reducing the risk a proposed substitution gets rejected late in financing diligence.
Savings that don't cost bankability
The goal is cost reduction that survives project financing scrutiny, not a cheaper part that saves money upfront and creates a financing problem later.
Savings that pass financing diligence
Find savings that actually clear diligence
Alternates are pre-screened against IE standards before they reach a financing conversation.
Reduce cost without reopening bankability questions
Substitutions target genuine equivalence, not just a lower price tag.
How it works
- 01
Flag the line
Mark the constrained spec, long-lead, over-budget or supply-short, on the BoM.
- 02
Match an equivalent
Sunhub surfaces spec-equivalent alternates with the engineering and bankability backup attached.
- 03
Clear the review
Submit the documented package to the IE and tax-equity team for sign-off.
- 04
Award the swap
Roll the approved alternate into the order without disturbing the rest of the BoM.
FAQs
What does spec-equivalent mean for a value-engineered equipment alternate?
Spec-equivalent means the alternate meets the same technical and performance requirements as the specified equipment, ratings, certifications, warranty terms, and performance figures, so it is a true substitute rather than a cheaper part that falls short. The point is savings that hold up under scrutiny, not a downgrade dressed up as an equal.
Does an alternate need independent engineer approval before it can be used?
On bankable projects, yes, an equipment alternate typically has to clear the independent engineer's review before it can be substituted, since the IE protects the financing party's assumptions. Sunhub screens alternates against IE review standards up front so they are more likely to clear diligence rather than getting kicked back late in the process.
Can value engineering find savings without affecting bankability?
Yes, that is the whole aim. By limiting alternates to genuinely spec-equivalent equipment that still clears the independent engineer's review, you capture cost savings without reopening the bankability questions that a true downgrade would raise. Savings that fail diligence are not savings, so equivalence is screened before the alternate is proposed.
Will a substitution survive the independent engineer's review?
That is the point of how alternates are presented. Each comes matched on power class and electrical spec with datasheets, certifications and bankability backup attached, so the IE reviews a complete package rather than an undocumented swap.
Could a value-engineering swap break my tax-equity case?
Alternates are screened against bankability and domestic-content implications before you see them, so you can weigh a cost or lead-time gain against any effect on the financing case before you commit.
