Is $20,000 to install a 19.8kW solar system with 32kWh battery storage a fair price?
Project Details
I am looking to future-proof my home for further purchase of EVs, use of ducted air conditioning, and a pool heater. I also want to maximize the current solar and battery rebates offered by the Australian government. I live in Queensland, where it gets very hot in summer, and I run the air conditioning a fair bit. I currently don't have EVs but am looking to get one in the future. I am wondering if this is a competitive quote and if there are things I should be checking or asking for, or if there's any general advice.
