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...

Solar Carport Design Optimization

Designing PV carports is an involved process, and key decisions—such as maximum system voltage, rapid shutdown requirements, inverter selection and location—must account for site-specific conditions. Here I discuss some of the main considerations...

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...
