Calculate Solar Project Wiring Needs Upfront for the Most Accurate BOM Estimates

In Industry Perspectives, Press Clips by

It’s not unusual for a bill of materials (BOM) to serve as an essential economic data point in early stage solar projects. The problem is, when it comes to Balance of System (BOS) costs, most preliminary BOMs only include racking and inverters, and not the cables/wires and other components that make up the BOS. Given that the cost of wiring is very expensive, calculating wiring needs up front is essential to develop a more accurate and informed total project cost analysis.

Thankfully, new advances in solar design software are automating BOM calculations, empowering developers with greater insight. With the ability to account for BOS accessory parts at the outset, developers can for the first time factor the complete BOS into project costs.
