SolarX inverter vs SMA inverter?

lunazero

Hello

Anyone have an opinion about quality of these inverters?
Or using German panels vs Canadian vs Chinese?

Had following quotes so far:

We have been told we can fit 13 panels on our roof.

QUOTE 1:

13 x 300W LG Mono all black panels
Solar X1 3600T inverter
Eco-Eye smart PV monitor
South facing roof - pitch angle of 45 degrees
Shading factor of 1.0
Predicted annual output 3,326.7 kWh
Irradiance zone 10
Irradiation level 853
20 yr FIT income of £19,643.91

Total cost is £6295

QUOTE 2

This company is visiting property tonight

14x 270W Trina panels
SMA inverter
GEO monitor

Total cost £5495

What do you think?

Is it worth asking them about 330W panels?

Thanks again for everyone's help!

I think the majority of panels used in the UK are produced by China and I think Yingli and then Trina were the biggest supplier of panels when I was doing my research in 2013.

I also have a SMA inverter which is a well known make within the solar PV world. However there seem to be more and more makes and models coming onto the market. SMA do have a good reputation but I haven't heard of the SolarX

The 20 year FIT income looks much too high to me.

Based on an output of 3327kWh & RPI increases of 3% (probably too high!), you'd be looking at c. £14,500.

(If savings made by solar use have been included in the £19,643, then it's closer to the mark.)

So what happened? DId you fit them?

I'm in DUrham and just starting the search for a good installer.
