Procurement Services

We at ACE assure to protect the owner’s interest by confirming that the technical, procurement specification and construction are adhering sufficiently to the standards and regulations. The constant review will be made at every phase of the project. The procurement selection criteria is based on the following:

Estimation of Bill of Quantity (BOQ)

Preparation of detailed BOQ (Bill of Quantity) with technical specifications for procurement of following major items,

  • Modules
  • Inverters
  • Module Mounting Structure (MMS)
  • String combiner boxes (SCB)
  • DC, AC, Control cables & Connectors
  • SCADA System, Module washing system, Power interfacing panel, Fire Alarm protection, Lightning system, Earthing system, Cables, Transformers, Switchgear panels, Civil works for building and AC electrical installation & miscellaneous supply.

Validation of equipment cost based on vendor quotes for various equipment and systems for firming up project cost.

Request for Proposal (RFP) & Review
  • Preparation of RFP documents with technical specifications, standard bill of materials (BOM)
  • Reviewing of all the required components to be procured, providing clarifications, submitting offer evaluation report
  • Review of vendor documents such as specification sheet/datasheet, obtained BIS/IEC certifications, test reports and certifications warranty documents, organization profile, etc.
  • Working out various options and alternatives and carrying out financial analysis for each option.
  • Presenting the results of the above analysis to clients to have a proper understanding of anticipated profitability and strategize to arrive at a competitive final price to be offered to the vendor.
