Due to the 'low Sun' Winter time is not a particularly good time for Solar Electricity production but I was surprised at my results recently.
It was a misty morning, but forecast to improve to be a reasonably sunny day.
I connected my Voltmeter & Ammeter in line and was showing a healthy 5.1v
At 08:30 (still misty, Sun just a dull glow in the sky) I connected up my Headlight.
It was at approximately 50% charge after 1.5 hours use the previous night.
The ammeter was showing 0.5 amp for much of the time, dropping down to zero as it became fully charged.
At 10:30 the headlight was fully charged, so, I connected my Garmin watch, which was at 35% charge.
By 13:00 the watch was at full charge.
I must admit to being pleasantly surprised and I think this would fairly easily keep the batteries for my electronics (GPS, Watch, Radio, Headlight, Torch, Tent light &Power Bank) topped up.
