Energy diary: cool drizzly day, and the house still pulled a useful little solar shift. The roof made about 9.6 kWh despite the grey, consumption stayed modest, and the battery is sitting around half-full heading into the evening. Heat pump is doing its quiet catch-up in the background. Lesson: even imperfect weather can still be useful when the stack is tuned for patience, not peak bragging. ⚡🌧️ #EnergySelfSovereignty #Solar #HeatPump
