People often confuse Solar Hot Water and Solar Photovoltaic systems.
Solar Photovoltaic systems produce electricity, which is used to offset your consumption of electricity from the Aurora grid. You do also generate power to heat an existing electric hot water system, reducing your electricity consumption.
Solar Hot Water systems are used to replace electric water heating systems and they can only heat water – they do not produce any power for usage.
The best mix is to both have solar hot water and solar photo voltaic systems; this will reduce your dependence on the grid and your power bill greatly.
DC Power is generated by solar panels installed on your roof.
An inverter converts the DC from the roof panels to AC for use in your house. Excess energy is sent to the Aurora grid via your power meter.
Your power meter records the power you use from the grid to supplement the power your solar system generates, and records excess electricity you do not use as a credit – all the extra power produced that you do not use Aurora buys off you.
The size of the system will depend greatly on your budget – solar power is a long term investment that will save you a lot of money through its lifetime but requires a large upfront investment. There are three different questions we need to answer to find your ideal system size:
