A good install company should explain & provide monitoring of your system’s performance on a monthly basis. A glance at a smart phone app once a month tells you all you need to know. Many customers want to see the instant output of a PV system to determine system performance, but this is unrealistic. Such data requires specialized equipment, which few install companies have. SynergyPower has this apparatus- We can conduct such a test on a clear day at a time when your panels have full sun (no shade).
