Hi there, were in NSW, we’ve had a couple of quotes for Solar System. We had a 12 panel 2kw system put in about 10 years ago and the Inverter is not working any more. Initially our thoughts were just replace the Inverter and quoted $2,100 for a Fronius 4kw inverter and $1,700 for a Sungrow. Keeping our 10 year old panels and rewiring them.
So we decided to get a quote for a totally new system and take down the old 12 panels.
Powersmart quoted for a 6.6kw system with a 5kw Sungrow Inverter (Dual MPPT) including upgrade to 10 year premium Manufacture Warranty and 22 x Canadian SolarKu Power 300w Panels (New super High Efficiency Panels PERC polypanels with 25 yr warranty) .
The other quote from a smaller local company (with a good reputation) was for a 6.3 System 21 x Suntech 300w Panels (15 yr warranty) plus a Fronius Inverter $6,929 or with a Sungrow Inverter for $600 less.
Both quotes included the Rebate and removal of the old system
Would love some constructive advice, thanks
