I have the same question. From Feb to July 2010 the HIT Hybrid Silicon Sanyo array (No.27) seems way down? Then it seems to come online and outperforms all others. I didn't find an explanation in the 'notes on the data' section under Historical Data tab either. Can anyone explain?
Looking at the HIT Hybrid Silicon Sanyo array on the interactive graphing page, it seems to perform well compared to other fixed array technologies since its installation was completed in March 2010. There was some brief downtime in November of last year, which is explained in the Notes on the Data page, but apart from that it has performed well.
Can you please elaborate on or provide a screenshot of the performance issues you are seeing?
There was actually a different technology model installed earlier on that array (no. 27), which was replaced with the current model of Q-Cells technology in June/July. We will be removing the older data soon. Additionally, not all the Q-Cells information is on the website yet so you may wish to wait until it is all on the website before asking any more questions about it.
