Hi,
I’m in Wagga, NSW, and have a couple of quotes for systems. I see much cheaper quotes around so that concerns me,
I’d have panels on the north, east and west facing sections of roof. The north face has some shading from a large street tree, particularly in winter.
I’ve been quoted:
6.65kw system net price $9,192
Jinko Tiger Neo 60HL4-V panels
Enphase IQ8AC micro inverters (5.04kw inverter power)
6.65kw system with Sungrow string inverters (same panels as above) net system price $7,833
Another provider
6.9kw system net price $12,709
REC alpha pure - rx series panels (460AA-PURE-RX)
Enphasr IQ8X-80-M-INT (5.7kw inverter power)
Are these quotes reasonable?
Is it worth the money to go for the most expensive quote? Will the extra spend be recouped over the life of the panels?
The company with the expensive quote sent their sales person round, rather than installer, and they have sold me on that system… but I don’t know if it’s worth the extra $3,700.
Are micro inverters worth the extra $1300 when 6 Jinko panels are likely to be partially shaded for part of the year?
Thank you
