Common Questions
Click a question below to reveal the answer.
What is the difference between the Aiko Stellar 3N+ and Neostar 3P+ ranges?
The Stellar 3N+ is the commercial/utility range with larger 144-cell panels in the 650–685 W range (2,382 mm tall, silver frame) designed for large-scale arrays. The Neostar 3P+ is the residential range with 54-cell (490 W) and 60-cell (540 W) formats in black frame with MC4-EVO2A connectors. Both use the same N-Type ABC cell technology and -0.26%/°C temperature coefficient.
What is the NOCT performance of the 665W panel?
Under NOCT conditions (800 W/m², 20°C, 1 m/s wind), the 665 W panel delivers 531 W with Voc 51.53 V, Vmp 43.25 V, Isc 13.26 A, and Imp 12.28 A. NOCT values give a more realistic indication of real-world output than STC ratings.
Is this panel MCS certified for the UK?
Yes. The Aiko Stellar 665 W is MCS certified (MR 50677721 0001/1110).
What degradation guarantees does the 665W panel offer?
Aiko guarantees ≤1% first-year degradation and ≤0.35% per year from year 2 to 30, backed by a 30-year linear performance warranty with optional Munich Re coverage.
