Keeping tab on your solar power-house

The monitoring solution for PV installations provides the following advantages

1. Provide data to calculate energy produced per panel per hr/day. This can help estimate the cost saving for standalone system as well as grid tied systems.
2. Total energy produced/saved data by itself is not as valuable as it is when compared with expected energy production for given location. There are several applications available that can give the annual expected energy production based on irradiation levels. This when compared for you system can help identify system performance issues. 
3. The above data is closely monitored by PPA providers as several of them provide minimum power production guarantee. The PPA provider would have to pay a fee to consumer in case minimum
   guaranteed power is not generated by the system.
4. This data can further be used to identify periodic maintenance needs. The panels gather dust and debris that reduce the power produced. The reduction in power produced is could be also a factor of aging of both panel and inverter. 
5. The monitoring information provides status feedback for the electrical elements including the inverter. In several cases troubleshooting can be done remotely to save time and provide the correct parts to repair technician. 
6. The data collected from in-service failures, can be used for systematic diagnosis of issues. This can help in improvement of component design and reliability.
