Off-grid panels 10–109 W

The range

Eight sizes, 10 to 109 W

All 18 V nominal except PA-S87, which is 24 V class (Vmp 21.1 V). Check the battery bank voltage before you specify — an 18 V panel on a 24 V bank will not charge it.

Electrical data pending confirmation. For PA-S10, PA-S40 and PA-S50 the catalogue's Vmp × Impp does not reconcile with the rated power (PA-S50: 18.0 V × 2.42 A = 43.6 W against a 50 W rating). We are not going to publish a number we cannot stand behind, so those three show "pending datasheet". Ask us before you size a charge controller on them.

Before you specify

What these panels are, and what they are not

What they are. Poly and mono small-format panels with a 18 V nominal output, sized for PWM/MPPT charge controllers on 12 V banks. Typical fit: telecom repeaters, street lights, CCTV, gate openers, small irrigation pumps, village charging points.

What they are not. Not grid-tie modules — no 1500 V system voltage, no IEC 61215/61730 module certification claimed for this range at the time of writing. If your project is grid-connected or tender-driven, use the 600–740 W TOPCon range instead.

Private label. The part numbers on this page are ours. The panels ship with our nameplate and our model code, not the producer's — that is the default, not an extra. If you need your own brand instead, that is a separate conversation with a minimum quantity attached.

Small panels for sites with no grid.
