Due to my job, I'm away from home 3 days per week. The remote monitoring gives me valuable real time informations regarding the yield and the health of the System. I can even remotely switch between Solar and Grid with my smartphone while having a beer in a bar. I also get a notification when the switching occurs automaticaly. Keep in mind that the system is online 24/24 - 7 days per week.

PV systems last for many years. Some parameters like the efficiency are prone to slow drift due to following factors :

• Solar panels getting dirty
• Battery wear out
• Terminal blocks getting loose

The database provides long term (20 years) recording and allows comparison between large amounts of data. This helps finding out the root causes of efficiency drifts.

PV systems must also be tuned to deliver their maximum yield. Curves and charts provide valuable data regarding the behavior of the system every day. These informations help in taking modification decisions.
