Hi guys,

I’ve got a quotation from solaroo and the parts they gave are

Solar modules: Longi Solar
Inverters: Hoymiles Micro-inverter HMS-1800

Want to ask if Hoymiles inverter any good? As compared to Huawei’s fusion solar?

Pretty noob at this.

Thanks!

I think the app they are using is Solaroo’s own mobile app. Any idea how bad it is for this app?

From what I have survey so far, the pricing seems to be the cheapest. Any comments here from the specs?

I think i’m ok so far using circa 7+ kwp system since my monthly bill is around 300 only. But yeah I wonder if Longi’s panel is able to generate 610w per panel compared to other brands like Trina, Jinko where its rates at 590w per panel?

Nope. I didnt specify what panel and inverter. I just asked for their quick default quotation as I was rushing.

As far as my research tells, usually panels you cant choose. Inverter you can ‘upgrade’ or choose other brands for an extra cost.

By the way, anyone has any feedback if say for panels from same brand ie Trina, some vendors use different power panels..ie 580w vs 590w vs 600w
Does it matter? I mean I understand it affects your total system power but would higher power panels comes with stronger materials(?) or whatever additional materials.
