Could you please comment on this quote, particularly on the recommended inverter. Its also much more expensive than the Solar Price Calculator suggests. Perhaps Tasmania has less competition than mainland Australia?
We’ve been quoted $7133 (after STC rebate) for a 5.185kW PV system with 17x Trina Honey M Plus (TSM-305DD05A.08) panels; Solis 1P5K-4G Inverter. Its from Home Efficiency Group.
We have a fairly small tin roof. Panels are 8 facing east (landscape), and 9 facing north (portrait). We get all day sun. The north and east sides are two storey.
The Solis inverter looks like a cheap option. Am I better off spending more?
Overall, how do I calculate the right size system? Do I really need 5kW?
I’m getting at least 2 other quotes. Which Tasmanian installers can you recommend?
