Looking again at Swedish number, the average house need around 200kwh per month for the period of December to April, and about half that for the rest of the year (https://hemsol.se/wp-content/uploads/Elforbrukning-villa-02....). If your maximum is 1000kwh your battery need for the winter will be around 125-150 kwh, not counting capacity for harsher winters or degrading panels. Using the power walls examples above, you then need around 10 units. |
