Frequently Asked Questions
How do I choose between the 610W, 620W, 630W and 640W panels in this series?
Pick by roof space: 610W and 620W suit homes, while 630W and 640W add efficiency and power for tighter spaces. All share the same size and 1500V rating.
Will this panel work with my existing string inverter?
Yes, with standard string inverters rated for 1500V system voltage. Confirm your inverter's MPPT window covers the module's 49.02V open-circuit and 40.98V operating voltage.
Is this a bifacial panel, and do I need a special mount?
Yes, it is bifacial with an 80±5% factor that captures reflected light; a standard frame works, and a light-colored surface behind it boosts rear-side gain.
What cleaning and maintenance does the panel require?
Routine cleaning with water to remove dust, pollen, or snow keeps output near peak; no specialized upkeep is needed. Avoid abrasive tools that could scratch the anti-reflective glass.
