Bioenno's 100-watt foldable solar panel

A few days ago I sold my two 100-watt Renogy panels that performed well in a 3-year stint at powering my station.

Their part-time replacement arrived today: Bioenno's 100-watt foldable solar panel.

As Murphy dictates, today is completely cloudy - but cloudy weather is good for photographing them without harsh shadows, so here they are for your inspection.

Folded, the panels are the size of a skinny brief case. A zippered pocket on the reverse side has the output cable which is terminated with a 120-amp Anderson Power Pole.

Can you say overkill?!

I removed it and will either put on a more shack-standard 15A PP or just wire it directly to the input of my solar controller which will also live in the panel's pocket.

Sunday is forecast to be sunny and here's the experiment I want to perform on one of those days:

Activate a park with the IC-705 and Hardrock-50 with the solar panels deployed. I'll use power analyzers on both the input and output of the battery to compare how many mAH the panels are putting into the battery and how much the radio/amp is taking out as I operate at 50 watts.

What I want to know (or at least get an idea of) is how long I could theoretically operate indefinitely, under sunny skies, without draining the battery. Is a 100-watt panel too much, too little or just right.

Incidentally, this weekend is Support Your Parks - Spring 2021 so there will probably be a lot of outdoor radio activity this weekend.

IC-705 for size comparison

  1. Hah - Support Your Parks - Spring!!! 26 degrees and snowing in Denver CO this morning. A pair of 3-500's are heating the shack nicely. I guess my support will be from inside....

    1. I know how you feel, but with opposite temperatures for the event - during Winter Field Day, it's often in the mid-60's here!
