Self Consumption


Consume what you generate. Intelligent energy management.


What is self-consumption?


With some power retailers announcing reductions in solar power buy-back rates, “self-consumption” systems are now much talked about.

Self-consumption is the use of solar PV energy directly at source – either immediately or delayed through the use of battery storage systems.

Self-consumption has become possible through the use of:

  • An appropriate unit size – the unit should suit each individual consumption situation
  • A change in consumption behaviour – consuming energy as it’s generated
  • Intelligent energy management through use of smart technologies such as SolaX Hybrid Inverters.
  • A battery storage system to store unused solar energy for consumption at a later date
  • A solar diverter to send unused solar energy to the hot water cylinder


Appropriate unit size

When sizing your solar PV system and deciding on the type of panels needed, we take into consideration your typical usage by reviewing recent electricity bills, the number of occupants in your household and your consumption patterns.It is important not to oversize the storage system as the investment costs would begin to outweigh the economic benefits.

Consumption behaviour

Self-consumption can be increased by up to ten percent by changing consumption behaviour: only using major electrical appliances during hours when most energy is generated.

Intelligent energy management

New technologies enable self-consumption by monitoring your energy export.  When the system detects that you are exporting your free energy it redirects it to your hot water tank or other heating source, ensuring that no additional power is ever imported to supply the hot water tank. Many of these technologies, such as SolaX Hybrid Inverters, can be controlled remotely through a smart phone app.

Battery storage systems

In a conventional grid-tied solar system, excess power is fed back into the grid earning you a credit on your power bill. Increasingly, the amount paid for electricity exported to the grid may be well below the price you pay when you buy electricity. So you may create power and sell it to the electricity retailer, only to buy back in the evening at a higher rate.

Battery storage allows solar panels to continue powering your world at night or when there is insufficient sun – without the need for importation of energy from the grid. The result is continuous, free solar power under any conditions.

Solar diverter for hot water

A hot water diverter is a device that sends surplus electricity from your solar power system to your hot water system.  This saves you having to use expensive grid electricity to heat water. It also means you can consume up to 95% of the electricity you generate. Effectively you are using your hot water cylinder as a battery!
