As you can see about 9 days during February the panels generated over half of our electricity. On 2/25 the panels generated roughly all the electricity we used. As we move towards June 21 when the Sun is the highest angle we'll have more and more days like 2/25 Over the whole month the solar panels generated roughly 44% of our electricity.
The reason there is so much variability from day to day in power output is due to the variation in cloud cover. The other factor that influences power output is how high the Sun is above the Southern horizon. In the summer months there will be more and more days where our solar array will generate all of our power (21 kWhrs) each day.
