Neutral Conductor Value Engineering in 3-Phase String-Inverter Systems

Value engineering is the process of maximizing the ratio between function and cost in commercial and industrial (C&I) or utility solar applications. By identifying low- or no-cost ways to improve energy harvest, for example, Pure Power...

Roof-Mounted Solar: Structural and Waterproofing Considerations in C&I Applications

In the first part of this two-part article, I covered the roof membranes and roofing systems commonly used in commercial and industrial (C&I) buildings. Roof identification is important because this information drives other design and engineering...

Aluminum Conductors in Solar Applications: How to Save Costs without Sacrificing Reliability

A principle goal of value engineering is to deliver long-term performance and reliability at the lowest cost practicable. One effective way to reduce the levelized cost of energy (LCOE) in large-scale or commercial and industrial (C&I) solar...

Free Voltage Drop

This is a follow up to the article 1500V Design Recommendations for 1500V String inverters, where we only briefly mentioned "Free Voltage Drop" and wanted to dive in a little deeper here.

When we value engineer a large solar project, we can take...
