Selection Process

Phase 1 solar installation, we requested quotes from three local companies, one was our local electrical company we’ve used, the other ones were new to us, one was recommended one we found through web search. Two of the companies provided a quote which were very similar. Both provided very detailed calculations with links to datasheets for all the proposed equipment.

Phase 2 and 3, we stuck with our installer of phase 1

Phase 4 we were recommended to Australian Hot Water in Mona Vale by our solar installer.

Reason for Selection

We selected Waterview Electrical as they had done work for us before, had knowledge of our home automation system (KNX) and we had references from other industry players.

Outcome

In phase 1 we reduced our electricity bill from $800 a quarter to $200. Once we introduced the EV we realised the charging from the solar panels was not as simple so by adding more panels and a battery we can now comfortably charge the EV from the solar panels plus batteries. Our savings are both a much lower electricity bill, typically $800 per annum plus savings of over $4,500 per annum in fuel.

What I would do differently

I would start by using a website that allows you to compare quote such as Solar Choice

Select a system that allows you to integrate your hot water system, with your EV charger, with your solar production to optimise the usage of the electricity you produce.
