Green Collar Careers - Solar Heating System Bill of Materials

Specifications for a solar heating system will drive the content for the Bill of Materials (BOM) required. 

The Solar Heat Site Survey workbook includes a worksheet Solar Heat BOM that identifies the list of materials required for nearly all Closed Loop solar water heating systems.  Components are grouped by classes:

  • SC - Solar Collectors
  • ST - Storage Tank
  • CL - Closed Loop subsystem
  • VE - Valves, Gauges, and Expansion Tank for Closed Loop subsystem
  • IRM - Installer Related Materials

Data Fields in the Columns are:

  • Class
  • Description
  • Quantity
  • Manufacturer/Vendor
  • Model Number
  • Specifications

The purpose of this BOM is to identify the content of the system along with specifications and sources.  You may want to add a column for component cost to add up the total system cost for system pricing.  You will want to keep these records and provide the customer with a detailed list of equipment - just don't include the costing data.

SC Component Data
Specifications should include the panel size and any ratings provided by the vendor such as efficiency or ratings.

ST Component Data
Specifications should include storage volume, insulation rating, and whether the ST unit is dual or single purpose.  Dual purpose units should include the water heater specifications.

CL Component Data
Specifications should include:

  • Pumps - voltage, current rating, flow volume (Gallons per Hour) pressure
  • Solar Panel - peak voltage, peak current, size
  • Controller - voltage, current, battery, input channels, thermocouple type, output relay rating, or output power rating
  • Thermocouples - type

VE Component Data
Specifications should include:

  • Pipe Diameters
  • Joint type (soldered, crimp, ferrule)
  • Gauges - range, thread size of coupling
  • Size and pressure ratings for Expansion Tank and Pressure Relief Valves

IRM Component Data
Quantities for the system should be given a liberal estimate based on the Site Survey.  Mounting Stilts and Mounting Brackets should specify the intended tilt angles and the roof or structural mounting type.

The BOM Worksheet has been provided as a guideline and may have other materials added depending on the system.  Note that all the materials provided by the solar heating kit wholesaler should be identified.

This BOM will be valuable for the installer to review along with the SRCC compliant installation data provided by the solar heating kit wholesaler.
