Which panels and inverter to choose?

[jgtec]

Thanks both!

I think I'll go for the Suntechs as they are much cheaper (I now have some quotes in) and the differences in output seem hard to quantify. I am not limited space-wise, taking away another reason for going with the Sanyos.

Hi All

Been following various discussions on panels and inverters over time. Am in the process of fleshing out the details of he system we shall be getting installed. We are looking at a 4kWsystem using Sharp 250w panels and a Fronius IG TL 3.6 inverter. Can anyone offer a view on the inverter proposed for a 4kW system? Should I be looking at the requesting a Fronius IG TL 4.0 or even two smaller inverters? Any advise grateful received!

I'd say that the IG TL 36 is perfect for this size of system. I certainly wouldn't advice using two smaller inverters either.

Do you mind me asking why you're choosing the Sharp panels?

 

[jag1972]

Not at all. Sanyo out of our price range and to be honest it is probably the familiarity with Sharp as a brand as opposed to some of the others on the market.

Btw, thanks for the advise!

No probs

 

[jag1972]

Any view on the panels? As I say, I've gone for Sharp out of familiarity but how would you rate the Sharp panel against say the Suntech (I take it it's not as simple as that though!)

 

[SolarCity]

I'd say that brand familiarity is the only thing going for Sharp panels. They don't compare with Suntech in any way at all.

There are better panels than Suntech, but not in the price range. I've yet to see better options than Sanyo (as a high end, high yield panel) or the Suntech (impressive yield for fantastic price) although I'm always on the look out.

Plenty to think about!

Thanks for that. I had planned to go for the Sharp panels but will certainly think about my options before proceeding.

 

[jag1972]

Just an update chaps. I've spoken to my installer and he's come back with the Suntech STP250S-20/Wd+ panels as a options. As I said earlier, I'm not as familiar with Suntech but the performance and warranty on these panels looks impressive. Cheaper than the Sharp as well!

Cheaper than the Sharp as well!

Better than sharp as well!!

I now have full quote on the Suntech's:16 x Suntech Wd+ 250w
1 Fronius IG TL 3.6 Inverter (Plus extended warranty)

Fully installed £10,666 (inc VAT).

Am I allowed to ask whether anyone knows or has experience of the company I am proposing on going with?

You may want to check the leadtime on the Suntechs, some suppliers are quoting Oct/Nov delivery.

Thats a great price, almost too cheap.

Hi all, I've had three quotes from different companies, I live in south Wales but not sure which to go for, one company has quoted

10 x Canadian solar 240w panels £8120.00
Or
10 x sanyo 250w panels £9140
Or
14 x upsolar 190w panels £7980
All with fronius inverter would the upsolar setup be better as it's 2.66kw
