Sunpower review: Monitoring unit is not working

The monitor unit is not working. I should be receiving information on how my solar system is working. It has stopped working for at least a month now. I contacted Sunpower and they said someone will call me back in 48 hours. Nobody called. After a week I called Sunpower back and they said I needed a new monitoring unit and they gave me a case number and they were looking for a new monitoring unit. This was two weeks ago. This company is not reliable. They still have not contacted me to let me know what is going on with monitoring unit. I still don’t know if my solar system is working.
