Frequently Asked Questions
A: Latitude +15° winter / Latitude -15° summer (Single-axis tracking recommended for >25% gain).
A: Requires changeover interlocks (4-pole isolation) and load prioritization via CUPS (Critical UPS Loads).
A: Increase conductor CSA, use CCVTs (constant current voltage transformers), or revise distribution topology.
