Battery Systems

Solar systems with batteries can dramatically enhance flexibility and self-sustainability.


The ‘grid’ is the name given to the electricity network that delivers power from generators (like the Clyde Dam) all the way to your home via pylons and power lines.

Solar battery systems are pretty much essential for ‘off-grid’ systems, where there is no back-up from the grid when your panels aren’t generation. However, they are also used in many ‘grid-tied’ systems, where some people even charge their batteries from the grid during their ‘free hour of power’.

Battery systems are becoming increasingly popular in New Zealand as their costs have come down considerably in recent years.
