Why Self Consumption matters
Your solar will offset your general household usage first, such as your dishwasher, fridge and general 'stand by' appliances. Larger loads like kettles, dryers, and air conditioning units, are a little more complicated. Even though you may be generating solar, the full load may not fit completely under the solar curve and may use some mains power to support the load.
Once your household needs are met any surplus solar will be sent to the grid for a 'Feed in Tariff'. The average household without batteries or load management devices will generally only consume 30-40% of the solar their systems produce, exporting the remaining energy for a low feed in tariff!
The aim is to 'shift' loads to fit under the solar curve in the most efficient way, to use more of the solar that is being produced. The difference between running a load inside the solar curve and exporting to the grid can be as much as $0.20 in savings if not more, depending on your energy plan.
A great example of 'Load Shifting' is Electric Hot Water. This load is generally heated as a 'Control Load' this occurs between 11pm-3am and is generally on a cheaper rate p/kWh. With the CATCH Power technology, you can shift this load and many others to be controlled from surplus solar. Saving your home hundreds of dollars every year.
