Customer Comments

  • Hi, I was wondering if there is any additional information regarding the connection for the panel. Is the plug center positive?

  • Lutorm / last year / 1

    I assume the polyurethane coating holds up to UV exposure better than the epoxy coating on the old models, but has anyone had one of these outside for 6 months or so and can comment on how they look?

  • Would this cell work for the SparkFun Sunny Buddy? The description for the Sunny Buddy says there’s a minimum voltage requirement of 6V, which this panel is rated for.

Support Tips

Tested output.

Tested output on this panel on Jan 14th around noon. (Winter sunshine) Summer time numbers will be better

A          V      Load
0.380 - 0.4 - 1 ohm load
0.380 - 0.8 - 2 ohm load
0.390 - 1.5 - 4 ohm load
0.395 - 3.0 - 8 ohm load
0.370 - 5.7 - 16 ohm load

350 to 380mA is probably the maximum you can expect from this panel.
