This graph shows the amount of electricity generated and the amount used for two people. It also shows solar declination and average daily temperature. The only natural gas used is for a water heater and a few days a year for heating since electrical heating is mostly used. We have neither a gas or electric dryer.

Data was gathered using the house meter, inverter measurements, and smart plugs. More information here: https://github.com/animatedb/solar.

Graphs were created usingPython with matplotlib.
