... tells you what % of max power you should be generating based on the local weather ?

For example today - bright sunshine through hazy sky - only seeing 66% of max rated value.
Would be great if there was some sort of "sun index" so that we could tell if its just atmospherics affecting everyone locally, or a specific issue with my panels.

Have a look at Solcast.com, it's more of a commercial site but they let you set up as a home user and it gives a pretty accurate assessment of the solar expectations for your system based on the local atmospherics.
