Solar Power
My house is completely disconnected from the state power electricity grid - commonly called 'off grid'.
The Panels
The house and workshop are run pretty well 100% from solar power. The solar system includes a 24V deep cycle battery with an inverter which steps the battery voltage up to 240V - Australian domestic voltage.
The batteries
There is an LPG powered generator which runs as a backup system for very cloudy periods, of which there are very few in this part of the world.
