Hi, sorry, new to this forum and new to solar power. Some Background: We are in the process of paying for a 4kW system to be put on our home on the Mornington Peninsula in Victoria. My father recently had a 3.6kW system installed (18 panels + inverter) from the same company for approx $13500.
We've been quoted for a 4kW system $16500 approx. However, I'm somewhat confused. We are getting the same inverter and the same number of panels as my fathers system.
When we questioned it we were advised that a 3.6kW inverter would "handle" 4kW, but to me we are being taken for a ride to the tune of $3000.
Can someone set me straigh by explaining how this works?
Any advice in laymans terms would be greatly appreciated!
Thanks.
