solar charging

[Tieutieu]

@surfboomerang today tried during a car travel.
With this amount, I didn’t won any single % of battery. Still have to experiment…maybe amount of sun behind glasses was not as strong as direct sun.

[surfboomerang]

@Tieutieu No, the amount of sunlight in the car is way less than outside. When I wrote 4-5 bars, I meant totally full bars. I was outside and the watch was facing the sun.

Also, if I understood correctly, the bars are only showing 50000 lux and the watch is capable of collecting more than that. So it could be that in my test the watch was receiving way more light than a full bar.

@surfboomerang thanks for explanations ! It Confirms I need more time (more sun !!) to have decent results. I have a long race to come next weekend, it will be a good test !
My only concern is that I my skin turns usually very quickly to full red when there is a bright sun !!

@Tieutieu
…the solar charging bar can be dual use… when one bar is full it’s time to think about putting on sunscreen

Is it known what exactly the stripes on the viewer represent? Suunto only reports light output in lux (or I didn’t read something) but that’s not information on how much of that energy we gained.
A cool addition, by the way would be a statistic info in the solar widget showing how much energy we gained from the solar panel during the day and the whole week

@aroo7 And graph in SA like steps/calories

@freeheeler I know that if the battery of my Vertical solar starts going up I need to apply suncreen more than once. Happened to me twice.

@vlado
I guess the big drawback is the useful surface of the solar panel. Each m2 of a conventional solar panels have a power around 250w which, extrapolating to our Vertical, would be about 0.25w at full sun.
As a general rule, USB chargers usually have an output voltage of 5V. So, for example, a charger that is capable of supplying 1.5 A (amps) at 5V (volts) will have a power about of 7.5 W (watts).
Solar charger does not more than a little help to extend the life of the battery;)

@valdis830 as the watch has a super high battery efficiency, luckly not so much energy is needed.
The solar option in Suunto Vertical will increase the battery time during activity significantly (in the range of +30%)!
This is leading the competition of comparable watches and really makes a difference.

Even if on a 2A power supply, the charging circuit of the watch will reduce the charging current to what is healthy for the battery. It will not reach 7.5W

Is it known what the bars on the widget graph mean? And how to interpret them when they are “full” of light?

[SuperFlo75]

Today, I went on holidays by car… the sun was shining on my left wrist about 4 or 5 hours… solar charging increased the battery from 78% to 80%… i could see a little effectiveness of solar charging!

[SuperFlo75]

I noticed all these days that the scale of the solar display is changing… when I go into the sun in the morning, the stripe of of display increases, and if the sun is strong, the stripe is ‚full‘… but after some more 10min periods, the scale changes and the stripes don‘t reach the max anymore… in the evening, when the sun goes down, it goes backwards and the scale is like in the morning. Regarding to this, it is not possible to reach a ‚full‘ max solar stripe at noon… who can explain? How can I increase solar charging when sittung in the full sun at noon?

Only one minute later…

@Tieutieu modern cars often have athermic window treatments in order not to become too much of a hot oven in the summer. I guess what does not warm your car is also what you would need to charge your battery through the solar panel…

[BrunoH]

@SuperFlo75 Just noticed the same thing. I had my first full solar bar, but the next minute the scale had changed . What’s going on?

[surfboomerang]

@BrunoH I noticed this behaviour if the watch collects a lot of sun in 10 minutes.
For example, if your watch collects enough sun for almost a full bar it will show this. If the next 10 minutes it collects even more because you intentionally point it towards the sun, the old bar is cut in half.

I suspect that the graph scale changes when the solar charge was near or over 100% for 10 minutes.

This was the previous post
@surfboomerang said in solar charging:

Is the some kind of scale on the solar history bars?

I noticed today that 2 10min bars were almost full. Once a third appeared, with a slightly higher value than the previous ones, the previous two changed to half full.

@surfboomerang the solar charging is very fast if there is sun i several tmes reset the watch before i noticed no charge percentage after resetting the watch the charging is very fast

[Danny poleg]

@Dimitrios-Kanellopoulos I’m trying to understand why two suunto verticl at the same point show a different level of solar charging, one very weak and the other a full circle

[inkognito]

@Danny-poleg Screen protector on one of them?

@Anton-Vanderpoel said in solar charging:

@surfboomerang the solar charging is very fast if there is sun i several tmes reset the watch before i noticed no charge percentage after resetting the watch the charging is very fast

Is there any truth in this? I don’t know if Anton is referring to soft reset or factory reset, but is there a possibility that solar charging might become more effective after wipeout?

[aroo7]

@SuperFlo75 I have the same and it looks very strange. Especially when you leave the watch in the sun for an hour and the straps don’t even get halfway up.
What are your experiences with charging? I never bumped up the battery more than 1% even when I left the watch in full sunlight for several hours. Not counting when the battery was almost full, then it charged to 100%, but this is probably a known bug so I don’t count that
