Accurate. Complete. Installation-Ready.

Your Bill of Materials is more than just an equipment list—it's the foundation of successful project execution. At Solartro, we deliver precise, comprehensive BOMs that ensure accurate procurement, eliminate costly ordering errors, and keep your solar installations on schedule and within budget.

From procurement to installation, our detailed BOMs bridge the gap between design and execution—ensuring every component is accounted for, every specification is accurate, and every project runs smoothly.

Why Accurate BOMs Are Critical

Eliminate Procurement Errors & Project Delays

A single missing component or incorrect specification can halt an entire installation. Our detailed BOMs ensure you order exactly what you need—the right quantities, correct models, and proper specifications—preventing costly delays, emergency orders, and frustrated installation crews waiting for parts.

Optimize Cash Flow & Inventory Management

Accurate BOMs enable precise cost estimation and strategic procurement planning. Order equipment confidently, manage inventory efficiently, and improve cash flow by knowing exactly what you need before you commit capital. No over-ordering, no under-ordering—just accurate material planning that supports your business operations.

Streamline Installation & Reduce Site Delays

Installation crews depend on complete, accurate BOMs to work efficiently. When every component is specified correctly and delivered on time, installers can work without interruption—completing projects faster, reducing labor costs, and improving customer satisfaction.

Support Accurate Project Bidding & Pricing

Comprehensive BOMs provide the detailed cost data you need for competitive, accurate project quotes. Avoid underestimating material costs that erode profit margins or overestimating that loses you bids. Our BOMs give you the confidence to price projects accurately and profitably.

Ensure System Compatibility & Code Compliance

Every component in your BOM must work together seamlessly and meet code requirements. Our BOMs specify compatible equipment that meets NEC standards, AHJ requirements, and manufacturer specifications—preventing costly field modifications and compliance issues.
