Use the SEANZ Solar Optimiser to estimate the cost of moving to solar.



If you are building or live in a remote area where the cost of installing power lines from the main electricity grid is too great; an off-grid solar electric system could be for you.

An Off-Grid solar power system is for those looking for complete independence from the power companies.  Typically this type of system is installed where the national power grid is either not available, or too expensive to connect to or you wish cut loose from the utilities and become self-sufficient.  Whether providing power for a couple of lights in a camper van, powering a modern tiny house, or the pad on Waiheke – the off-grid solar power system offers a solution with a combination of solar power generation and energy storage batteries meaning you can power what you want, when you want.

Off-grid systems need to have both their solar power and their battery system sized for the job.  This can be a very simple process when the required power output is known, we will take your list of appliances you wish to have and complete a load assessment which will tell us exactly how much power you need to produce and store, this needs to be carried out to to ensure your system will provide for you when you need it most and last as long as possible.
