At time of highest 'capture', there will also be 'demand', as the liquid pumps in the house will be working flat out, but these are low energy demand pumps. I shall also put additional demand onto the battery, such as the laptop, printer, broadband modem, hard disk, cordless phone. All useful in case of a power cut in the grid.
You have to get the balance right. If demand exceeds supply, then systems do not work, but worse than that, a fully flat lead-acid battery is difficult to restart.
