Prepared for lenders, CDCs, and federal agencies to SBA SOP 50 10 8, USDA RD Instruction 5001, and conventional underwriting standards. Fiduciary duty runs to the lender and the agency, never the borrower. More than 4,000 studies since 1998 covering $40.2 billion in evaluated project value.
Solar feasibility joins resource to revenue contract: the production estimate from irradiance data and system design — independently tested against P50 and P90 cases — the PPA, community-solar subscription, or merchant exposure behind the revenue line, interconnection position and upgrade cost allocation, and the incentive stack (investment tax credit, state programs, REAP grant where eligible) modeled at its real value and timing. Land control, setbacks, and decommissioning obligations are documented as the agency expects.
Methodology uses NREL irradiance and production modeling, interconnection-queue and utility data, PPA and subscription review, and installed-cost benchmarks by system class. Coverage is tested at P90 production under the contracted case, with REAP documentation prepared to RD Instruction 5001 where the program applies.
Every Wert-Berater financial model is fully linked with no hardcoded values, so any reviewer can stress any input. Deliverables comprise a complete narrative report and the linked Excel model, with ten-year pro forma, sensitivity analysis at ±5, 10, and 15 percent, interest-rate stress from +0.5 to +3.0 percent, and ratio analysis benchmarked against RMA and IBISWorld data.
SBA engagements are prepared to SOP 50 10 8, including its debt-service-coverage minimums of 1.15x operating and 1.00x global. USDA engagements follow RD Staff Instruction 5001 across the Business & Industry, Community Facilities, REAP, and Value-Added Producer Grant programs. Conventional engagements are built to the lender's stated coverage standard, typically 1.20x. Clean-energy engagements are prepared to USDA RD Instruction 5001 where REAP and B&I apply — including the energy-production documentation, incentive analysis, and payback arithmetic REAP requires — and to conventional and institutional standards otherwise, with interconnection and incentive risk addressed directly rather than assumed away.
Representative clean-energy work includes a $52,688,000 green carbon project evaluation and renewable-energy feasibility within the firm's USDA REAP and B&I practice. Independence is non-negotiable: determinations follow the evidence and are not revised under pressure, and studies are built to pass lender, agency, and third-party review without exception items.
