The Complete Guide to Solar Project Management & BOM Control

Solar panels, high-capacity inverters, mounting structures, and thick copper cabling are high-value assets. If your operations team is manually tracking stock levels, you will face either overstocking that ties up cash flow or material shortages that leave installation crews sitting idle in the field.

A robust Bill of Materials (BOM) control system prevents these issues by linking design dimensions to inventory levels. When a system layout is finalized, OnlyWorks automatically reserves the exact quantity of modules and racking structures required, preventing them from being double-allocated to other active projects.

Establishing Goods Received Notes (GRN) controls

When supplies arrive from vendors, they must be checked immediately against your original Purchase Order (PO). Use a structured Goods Received Note (GRN) to document details and register serial numbers for panels and inverters before unloading. This holds suppliers accountable for transit damages and registers hardware warranties from day one.

• Associate unique serial numbers with specific project records for warrantee tracking.
• Track material transport to job sites via digital transfer logs.
• Conduct monthly physical audits of stock to reconcile database records.
• Flag variances between design BOM requirements and actual stock consumption to catch material leakage.

Real-Time Project Profitability

By linking purchase orders, vendor invoices, and labor expenses directly to the project dashboard, OnlyWorks calculates the actual profitability of each installation in real time. Managers can easily compare budgeted costs against actual spend, protecting solar EPC margins.
