Seraphim v Hyundai

jrfarrim

I'm currently in the process of gaining qoutes for a 4kwh PV installation.

One installer who is coming in cheapest so far is quoting £5200 for the following.

16 x Seraphim Energy 250w all black mono
1 x Solis 3.6 Dual MPPT
Schletter Mountings
Landis+GYR 1 PG Generation meter.

He's given another option for the panels for an extra £295, 16 x Hyundai 250w Black framed panels (HiS-S250RF(BF)).

The Hyundai's run at 16.9% eficiency against 15.4% for the Seraphim panels. Is this enough to justify the extra cost of the Hyundai panels or will I just be paying the extra for a known brand name?

Thanks

If the panels generate 250w, that's what they generate.

The efficiency just effects how big they have to be to generate the quoted watts. So, a more efficient panel is capable of generating the same watts from a smaller surface area.

In respect of efficiency, essentially all this means is that the Hyundai panels are a little bit smaller. They won't necessarily produce any more output.

Hi. Efficiencies can confuse. A 250Wp panel is pretty much the same as any other 250Wp panel, and should generate the same amount per year.

Where efficiency comes into it, is just how much space is needed to produce that 250W.

16.9% is 1.4% more than 15.4%, an increase of approx 10%.

The Seraphim panel is 0.992m by 1.64m = 1.62688m2
The Hyundai is 0.998m by 1.48m = 1.47704m2

So the Hyundai is approx 10% smaller.

Don't let anyone try to confuse you with solar efficiencies. A 250W panel will produce as much electricity as another 250W panel. The Hyundai higher efficiency just means it can achieve this with a slightly smaller panel. This only becomes relevant in relation to roof sizes and what will fit... Obviously if the Seraphims don't fit, the Hyundais will be the better choice! They'll produce just as much electricity for practical purposes though.

Thanks Guys, got it now. Space is not an Issue so Seraphims it would be. Now for some negoiations as my aim is to get an Installed system sub £5000!

Try posting your rough location on here and you may get some recommendations. I've just had a price for a friend of mine that comes in at £4495 for a 4kWp system.

I'm in North Manchester. 4 quotes in so far, 3 of those have been over £6k for a 4kwp system. From what I've been reading £4.5k is realistic at the moment.
