Installer Quote Review & Validation

Installer Quotes Are Hard to Compare and Harder to Trust

Installer proposals are built using different assumptions, pricing structures, and performance forecasts, making side-by-side comparison difficult. Without independent validation, decision-makers are left to rely on vendor-provided models that may obscure true costs, risks, and long-term performance.

Different Assumptions Behind Every Quote

Installers use their own assumptions for pricing, performance, incentives, degradation, and timelines, making proposals look comparable when the underlying economics are not.

Headline Numbers Mask Risk and Exclusions

Quoted savings and payback periods often exclude key costs, contingencies, or downside scenarios that materially affect long-term outcomes.

Vendor Models Are Built to Sell, Not to Invest

Installer models are typically structured to highlight projected benefits, making it difficult to assess true economic value and risk without independent review.

Turn Vendor Quotes into Investment-Ready Comparisons

We independently review pricing, assumptions, and performance claims so you can compare proposals on true economic value, understand downside risk, and choose the option that best protects your investment.

Comparable Quotes

Compare installer quotes using consistent economic assumptions.

Lower Downside Risk

Identify optimistic inputs and hidden costs before committing.

Confident Approval

Make capital decisions with independent validation.

What the Analysis Covers

An independent, like-for-like evaluation of installer proposals to clarify true cost, risk, and value before you sign.

Quoted System Costs: Review of EPC pricing, equipment assumptions, scope inclusions, exclusions, and hidden cost drivers.
Production & Performance Assumptions: Validation of generation estimates, degradation rates, availability, and performance guarantees.
Financial Assumptions: Assessment of financing terms, incentives, escalators, and cash flow assumptions embedded in the quote.
Returns & Payback Claims: Verification of IRR, payback period, savings projections, and downside exposure if assumptions miss.
Like-for-Like Comparison: Normalized comparison across multiple installer proposals to isolate real differences in value.
Risk Allocation: Identification of who bears performance, construction, interconnection, and long-term operating risk.
Red Flags & Optimism Bias: Detection of aggressive assumptions, unsupported claims, or structures designed to sell rather than protect capital.
Decision Summary: Clear recommendation on which quote holds up economically, and why.
