Hooked the Ecom box up to my batteries and deployed the solar panel in the backyard.





Don't have a ampmeter on the leads from the solar charger to batteries (to compare what I have coming in from the panel to what is going to the radio) but it seemed as if the panel was able to handle the 1.03A draw of listening.  I had a steady green light unless some clouds came by, then I got a blinking green (which meant it was trying to charge the batteries--I assume that means the income was not enough to handle the draw and brought the batteries down a little), but it recovered quickly.

I then heard W100AW calling CQ from Oregon, and with the power set to 30 watts, I gave him a shout.

He heard me. Hit a max of around 5-6 amp draw when broadcasting, but everything worked as it should, and I don't think I touched the batteries (as the charged showed stead green).

For me, that makes my day.

Very cool.

I've been unable to contact anyone, bands have been s8+ noise for me in Miami, FL.


Which solar panel?

There is a lot of noise.

The panel is a ALEKO 140W 140-Watt Monocrystalline Solar Panel I got off Amazon (before they started getting tax from us). I just store in my reloading room and move it out back when I want to use it.





I put an aluminum piece which I can fold out to prop it up.





The plan is to try to use just the go box every weekend (at least through Hurricane season) to get used to everything.

At one point in my life I spent 3 years living in an old school bus. Winters here in Maine were tough but with a decent wood stove & 4 deep cycle batteries I managed quite nicely.
I had a 45 watt panel on the roof which served me well from April to October.. After that the sun was too low for good insolation.
For awhile I charged with a 2Kw genny & a battery charger. Next I obtained a few parts from The Epicenter (universal bracket & pulley) & bought a hundred dollar, Honda knockoff motor from a local junk store. Add a few more pieces from a junk yard & $20. bux worth of hardware & a used alternator I had myself a 12 volt genny.
I rationed the charge time to ~~ 1 quart of gas per day... which was very sufficient to run a small light, a 2M Yaesu (on 24/7) & a Yaesu 847 daily for 3-4 nets. Had dipoles for 40 & 80M, quarter wave verticals for 2, 6 & 10m

So.... The bottom line being... It IS do-able. However it does take work, knowledge, patience & a good amount of self discipline & power management to keep it all well charged & running when you needed it the most.

I still have the genny I built & it's a solid machine. I use it several times a year at field day etc..

If I can find a camera I'll post some pix....my cam didn't float ....'nother story........
