Storage capacity is determined based on optimal performance yields of a Smartflower system. With the storage options on offer, personal use levels of 80 – 90% are attained according to personal application habits. In theory it is possible to raise the self-sufficiency level to 100% with the application of a large storage unit (>10 kWh). Additional acquisition costs would make no economic sense in relation to use. What is pivotal is the use of small storage units in combination with simultaneously intelligent user control. (i.e, turning on washing machines at midday).
