I no longer see solar forecast in vrm if I click it see below
A minimum amount of recorded solar irradiance data is required to show the forecast. This takes up to 3 hours.
In the next days the forecast will become increasingly accurate. Maximum accuracy is reached after 28 days.
I have have the same issue, it used to show the forecast then just seemed to stop and now I just get the info message as shown above (s1277).
I am not exactly sure yet that it is a bug?
It was a design choice that if the location changes, or the location is reset, that forecast should also be reset.
However in the cases where the location change is very small (like a moored boat with GPS), then the VRM team is already aware and looking at an improvement so that the location change needs to be significant.

There is a problem if you are using s GPS mouse.
I have been 3 weeks in the New Mexico sun and it still reports "collecting data." I have no geofence set and the location is set by an externa USBl NMEA 2000 GPS. It worked for several months until about 4 weeks ago.
Seems like a bug to me.
Somewhere on the Bug / known limitation / intended feature continuum
It was originally different, but people were complaining that they were moving their sites and then getting inaccurate forecasts, so it was changed.
Each time the location changes at all, which happens if any GPS is connected even in a stationary vehicle, the algorithm is reset. The team is looking into making this less sensitive, but there is a case for both extremes so it might be a while before a compromise is found.
