So I got a quote for a solar system from a door-to-door salesman (which is already a bit suspicious) from Clean Power Australia, but I don't know enough about solar to know if it's any good. I know the prices vary wildly, as does the quality, but I don't know what is good hardware and what isn't.
From scanning around a bit, it seems this is just about the most expensive system I can find, so I feel as though this isn't a good deal.
Notes about the quote:
- it is an 8.6kW system with a 10kW inverter because, due to our roof configuration, apparently it was either going to cost $300 in optimisers, or we could pay $500 for a higher kW inverter, which might see some extra kW in summer, and allows for future expansion without requiring upgrading the inverter. [EDIT: to clarify, we went with the $500 inverter upgrade which is what is in the quote below. The system normally comes with a 7kW inverter and is $9999, but I've listed the upgraded version and price below.]
- estimated annual electricity bill savings came in at $1700
- payback estimate time is 5y 9mo
- apparently the 25 year Hyundai warranty is transferrable, meaning we can use it as a selling point if we decide to sell in future (as the warranty will transfer to the new owner)
So the quote is $10,499 and the hardware is:
