Case Study

The reason for installing solar with battery backup was not just to save the planet but to get rid of the monthly electricity bill — and given the right weather conditions, generate enough power to supply to the main grid and receive payment for power supplied.

As I have a renewable energy background, I knew generation was the key to the success of my main goal: to end the monthly electricity bill and be paid for generating power. This is where receiving payment for supplying power to the National Grid comes into play, not as income, but as a fund for the maintenance of the system during its lifecycle. The investment part comes from receiving a bigger return on the dollars invested in the solar system versus a monthly return from a Superfund or a bank, by not paying an electricity bill of anywhere between $100 and $300 a month.

In researching the above, I came across Greenfox NZ, agents for Super Capacitors. The first thing that struck me was the 45-year lifespan which doubled the lifespan of the solar installation. The other key factor was how this battery operated — it is not your conventional type of battery. The battery charges up very quickly (unlike conventional batteries which trickle feed) and once charged it allows the solar power to direct all its power to either the local electricity network, while maintaining what is required for the property.

The Super Capacitor will not carry the same Health & Safety risk as normal batteries (Lead Acid & Lithium). The H&S Standards for battery installation around private properties is in the review process (Australia and New Zealand) and is going to be very strict when released. The Super Capacitor I believe will not carry the same restrictions as normal batteries regarding installation.

“Do I like the super capacitor? I think it’s wonderful. Will I be adding another super capacitor? Yes when I can afford it.”
