Edge of cloud event captured

[sternwake]

My 100 watt Sunpower 'flex' panel, to which I added a light frame, to keep it from flexing so much that it prematurely fails,  and assist in  its ease of portability, and positioning, and storage, was employed today, as the marine layer was burning off around noon time.


I have an additional 45 amp anderson powerpole 10awg input to my Bluesky 2512i Mppt solar charge controller, which makes it easy to hook one of my inline wattmeters to, and see just how much the portable parallelled  panel adds to the harvest from  the roof mounted dirty 2007 Kyocera 130gt panel, in parallel with a 2011 unisolar pvl-68 watt panel, into batteries which have not yet been brought to absorption voltage.

I waited for a cloud to pass and watched wattage delivered from 100 watt Sun power flex panel with camera aimed at wattmeter.


Battery voltage of 5+ year old Deka intimidator GC-2s,  was still under 14,  and about 35 amp hours from full when I added the flexpanel.

max captured by camera was 110.2 watts from a 100 watt panel, peak recorded  via wattmeter, was 110.7 watts
   


When no more clouds were around, to cause the EOC harvest Yoyo, and 100 watt  panel at full temp in full sun with ~ 80f ambient,  max output settles into the 82 to 85 watt range.

I and my batteries would  enjoy a permanent 300+  watts on the roof, but that is unlikely to occur.

Honestly it is easier to just plug in for an hour or so, and let the meanwell's adjustable voltage power supply's  40 amp potential bring voltage to absorption until the solar can take over and hold absorption on its own, but I've been working on drivers door hinges and the Sunpower panel mounted to shading the door, and I enjoy not needing grid power.
