After three years of operation, I have a summary of the system generation. The data is collected from the SMA inverter that has an Ethernet cable connected to the internet and is pushed to a cloud database that is accessible to customers.
The three year average equals 5294 kWh (although I know I had a few data losses that should make it more like 5400 kWh). Not bad from a ~4800W nominal panel power system.
Here is my home metering net summary over the past 3 years. Negative numbers on top are solar generation surplus and positive numbers below are consumption. There are some data holes from faulty connections a few times but it gives the picture. Summer generation generally exceeds winter consumption. Hopefully I get a full data set this year and can get an accurate reading beyond the flawed meter data from the utility.
This is currently far exceeding our consumption but will change with our future purchase of either an electric or PHEV car along with a planned transition to a heat pump space and water heating system. I would like to make these transitions sooner rather than later but am stuck with poor product choices that are currently on the market. We hope that this opens up in the next 2 years.
