A mere three years ago the solar benchmark for electrical potential was 600 volts DC. Then 1,000 VDC systems came of age, and now in less than three years, 1,500 VDC will be the new notch carved into the bench. Sooner rather than later, the benchmark could hit 2,000 VDC. Yet, despite the rapid U.S. …
