What's Included

Complete Renewable Energy Takeoff

Every renewable energy takeoff is 100% drawing-referenced — every panel, inverter, conduit run, and civil item tied to a specific PV layout drawing, electrical one-line, or civil plan.

Solar PV Array Quantities

Panel counts by wattage and model, racking system LF and unit counts, inverter counts by capacity, and combiner box counts — from solar PV drawings and equipment schedules.

Battery Energy Storage Systems (BESS)

Battery module counts, inverter/charger counts, BMS units, and enclosure counts — from BESS drawings and equipment schedules. Electrical service requirements noted.

Electrical Balance of Plant

LF of DC and AC conduit by size, wire LF by gauge, disconnect counts, transformer counts, and utility interconnection equipment — from electrical drawings.

Wind & Generator Systems

Wind turbine counts by capacity, generator set counts, transfer switch counts, and fuel system quantities — from equipment schedules and electrical one-line diagrams.

Civil & Structural Balance of Plant

SF of ground-mount racking foundations, CY of concrete for equipment pads, LF of access roads, and fencing LF — from civil and structural drawings.

Excel Workbook + Annotated Markups

Quantities in Excel organized by system type and array zone — with annotated PDF markups tied to PV layout drawings, electrical one-lines, and civil plans.

Why Choose Us

The Union Estimating Difference

PV Layout & One-Line Reading

We read solar PV layout drawings, electrical one-line diagrams, and string sizing documents — capturing every panel, inverter, and balance-of-plant component.

Electrical & Civil in One Deliverable

Electrical balance of plant and civil/structural quantities are covered together — one takeoff for the complete renewable energy project.

BESS & Storage Included

Battery energy storage system quantities are included when BESS drawings are supplied — module counts, inverters, and electrical service requirements.

Fixed-Fee Quote Before Work Begins

We review your drawings and provide a firm fee before starting. No hourly billing, no surprises.

48–72 Hour Standard Turnaround

Most renewable energy takeoffs are delivered within 48 to 72 hours. Large utility-scale projects may require additional time.

System Design & Engineering Excluded

We quantify from your supplied drawings. PV system design, energy modeling, interconnection engineering, and installation are not included.

Delivery Packages

Quantity-Only or Cost Estimate

Two delivery packages available. Quantity-Only delivers measured quantities with no pricing. Cost Estimate adds agreed material and labor pricing using our proprietary database and current supplier/vendor quotes — all assumptions documented.

Quantity-Only Package

  • All measured quantities in Excel — LF, SF, CY, unit counts by type
  • Annotated PDF markups showing every counted item
  • No pricing, no labor rates — quantities only
  • Use with your own pricing or subcontractor quotes

Cost Estimate Package

  • Quantity-Only: panel counts, LF, unit counts, and annotated markups — no pricing
  • Cost Estimate: material pricing from proprietary DB + current supplier/vendor quotes
  • Labor pricing based on trade productivity and documented wage assumptions
  • Subcontractor budget allowances for specialty electrical and civil BOP where applicable
  • RSMeans used only for government/DOB work where required by scope agreement
