London Suburb Dweller's Megawatt-Hour Battery Dream

A London suburban resident attempts to calculate the battery size needed for complete home energy self-sufficiency. Using data from their solar panels (generating 3800 kWh annually, matching their consumption), and years of data analysis, they find a massive 1068 kWh (nearly a megawatt-hour) battery is required to store summer's excess energy for winter use. While currently unrealistic due to technology and cost, they remain optimistic about future battery technology advancements and price drops, envisioning a future where every home has such a battery, achieving complete solar self-sufficiency.
