It’s 45 degrees outside (yes Fahrenheit!) That’s 25 degrees below my comfort level. It is also quite damp and raining. It’s not quite cold enough for a wood fire but it’s great weather for a heat pump! Our Mitsubishi HyperHeat has been keeping it nice and cozy in here. And doing it on a budget too!
The chart below shows our energy production in green and consumption in red over the last 3 hours. The solid green area is excess solar energy that was sold back to the utility. Solid red area is energy we bought from utility when our load exceed our solar generation. The white area under the graph is energy that we generated and then used on-site.
Even with all the rain and clouds our 9kW solar PV array is covering all the energy loads of the house. This includes the heat and hot water, refrigerator & even the coffee maker!
