Suunto Vertical Titanium Solar: Reduced Solar Harvest Efficiency Over Time?

[mehmetalidurgay]

Hi everyone,

I’ve been happily using my Suunto Vertical Titanium Solar for about a year and have been very satisfied with it overall.

However, I’ve noticed a change in the solar harvest performance. When the watch was new, under the same sunny conditions, the solar harvest indicator would often show High or even Maximal levels. Recently, in what appear to be similar sunlight conditions, I’m mostly seeing Low to Medium solar harvest values.

Before

After

Has anyone experienced a similar decrease in solar harvesting performance over time? If so, did you identify the cause or find any solution?

I’m wondering whether this could be related to sensor aging, changes in calibration, software updates, dirt or scratches on the solar panel area, battery behavior, or simply seasonal differences in sunlight intensity and sun angle.

I’d appreciate hearing about your experiences and any recommendations for troubleshooting.

Best regards,

@mehmetalidurgay I’m having the same behaviour with the watch than you, the max level that I see is medium. I think it is a bug in the widget that does not show the real harvesting. I think that because when the watch is under the sun the bars show solar harvesting.
I’ve read that some people have has their unit exchanged because of faulty solar panel but I do not know if the issue that they noticed was the same than us.

@mehmetalidurgay I see max on mine the last time I used it. I will check this again tomorrow. There have been reports of the wire connecting solar collector to the watch internals failing and some have had their watches replaced. You could contact support.

@Brad_Olwin Brad, please check. I can only get medium in my watch but the bars with the accumulated harvesting acan be filled to the top. I still have 3 months of warranty, so I would use it if necessary.
