Solar charging on cloudy days
The 12s makes the charger have a bit longer run time during the day (more power loss), but also a bit more charging time. For the 4s3p the charger just powered on, never started charging, because the charger powers on when solar voltage goes above 120v, but charging doesn''t start until it reaches 150v, which never happened during these days.

Does anyone have experience using the Dark Energy 15W Spectre solar
Solar doesn''t fare much better, anything under 9 days is better served with batteries rather than solar (for its weight) before considering weather and that you have to stop to charge if traveling. If you''re looking at long term survival then you''re likely going to be static somewhere with resources, so solar makes more sense, but for most people just taking another powerbank is most sensible.
