Summary

Shade tolerant in A small frame, 19.7 percent efficient

The RSP120DC-ASR is Renogy's 120 W ShadowFlux rigid panel, a 48-cell N-type glass module built to keep producing when part of it is shaded.

Verdict

It suits a van or boat roof with room for a 41 x 23 in panel and shade from racks or rigging, at a lower output per square foot than the 200 W ShadowFlux.

Complaints

Over-voltage warning on a power station, per one owner

One r/bluetti owner of the 120 W panel reports an over-voltage message on a power station unless the panel is shaded while connecting, after which it delivers about 86 W.

GoogleProduct-line6.0 out of 10

Forum discussion of the ShadowFlux range centres on the 200 W size, and a DIY Solar Power Forum request for real-world 120 W shading data drew no owner results. On the 200 W panel, one member works Renogy's 25 percent cell claim down to 20.7 percent at module level.

About 110 W aimed at the sun, per one tester supplied by Renogy
36 W with half the panel covered, per one tester supplied by Renogy

Primal Outdoors, which received the panels from Renogy, measured about 95 W with the 120 W panel lying flat and about 110 W aimed at the sun. With half the panel covered it held 36 W, and about 10 W with three quarters covered.

Description

The Renogy ShadowFlux 120W (RSP120DC-ASR) is a 48-cell monocrystalline N-type rigid panel with a tempered-glass front, an anodized aluminium frame and 16-busbar cells. Renogy's datasheet rates it at 120 W, 28.9 V and 4.21 A at maximum power, with a 33.7 V open-circuit voltage and a 4.57 A short-circuit current. It measures 41.42 x 22.76 x 1.18 in and weighs 15.87 lb. Renogy describes its anti-shading design as cell-level bypass technology. The junction box is rated IP67 and the MC4 connectors IP68, on 14 AWG leads of 23.6 in. Renogy's datasheet gives a temperature coefficient of Pmax of -0.29 percent per degree C and an operating range of -40 to 185 degrees F. Renogy covers materials and workmanship for 5 years and output for 25 years at 80 percent, by its datasheet and warranty document. It sells singly at $129.99, in a 2-pack at $259.99 and in a 4-pack at $493.99, and the same listing offers a 600 W 12 V ShadowFlux kit with a 5.12 kWh battery at $3,199.99.
