Amazingly, no. I thought we were going to have to, but our natural usage peaks at about 20 to 30kWh per day, and we can generate far more than that on a sunny day. Thanks to the oversized PV array, we generate power even in cloudy conditions. The PV array is also split in half and oriented east+west so it catches more sun through the entire day instead of a midday peak. For things like clothes washing, drying, and hot water heating, those are the heavy users but can be moved to times of good sunlight. We only run out of power if we have 2 or more days of heavy rain in a row, which only happens a few times a year.
