Ok, i have to ask, why the solaredge? Do you have shading? Any shading? A little bit of shading?
As for the price....forget it...too expensive
8 x benQ 285W panels are a little over £1200 RETAIL(sunedison equiv)
1 x inverter(single string) £500
1 x scaffold £500
Racking/cables/switches etc etc £500
Price £2700 + fitting
There are also higher rated panels(benQ 330W) to make the most of a small roof
Again...above prices are retail NOT trade prices of which the installers are privy too2 kWp SEbE , 2kWp SSW & 2.5kWp NWbW.....in sunny North Derbyshire17.7kWh Givenergy battery added(for the power hungry kids)0 -

Bit of shading from a chimney - up to 8% affected on their snazzy colour system on panel piccy.
So factoring in the higher wattage panels and offer of monitoring equipment they have also what sort of cost would you suggest?
Thanks again.0 -

Not sure exactly how costs scale with smaller numbers of panels but I was quoted £5995 for twelve BenQ 330W panels. This was by a seller on EBay who strangely enough had it listed for about £500 more.
I think the duration of the shading is going to be more important than the amount. Solar modules are very sensitive to shading and unfortunately a small amount on one panel will dramatically cut the output without some mitigation. Even something like a TV antenna can do it. Once one module is slightly shaded it will drag the whole lot down... You might think 8% shading will only cut output by 8% but that is not how it works.
On the other hand if the shading is only say early or late in the day especially in winter it may not be important as you'll be getting little generation then anyway and even a big percentage of very little isn't much.

8 panels is £2400 retail(roughly)
Micros £85 each(retail) £680(roughly)
Fixtures & fittings with scaffold £1000
In summary, same price you're quoted but a higher kWp system. Just bear in mind these are retail prices and any decent installer will get the kit a lot cheaper so maybe even shave a few quid off that price.
ps, have a look at wattson solar plus with energive for your monitoring needs, there's plenty of guys on the renewables thread that will happily share a link to their online monitoring for you to feast your eyes on.
Do you not have any other rooves?2 kWp SEbE , 2kWp SSW & 2.5kWp NWbW.....in sunny North Derbyshire17.7kWh Givenergy battery added(for the power hungry kids)0 -
We have a North facing roof - same size and another smaller roof and a flat roof but lower on the North side - will get the 2 local companies to survey and come back here - thanks all0

Hi
Got 3 companies visiting -now know the roof is SE, other NW
Shading is basically a chimney and rising edges - that's it so wonder if the optimisers are worth it at all?

Hi Andy,
DO NOT underestimate the effects of shading....ever, it takes only one panel to have around 10-15% shade to bring the rest of the panels down with it.
Now, where exactly is the chimney? Is it to the west side of your roof, bottom (near gutters) or to the east. It is important so we can understand just how much of a difference it will make now you have the right direction of the roof.
Ps, LG quote, still to much.
Maybe post your rough location(nearest town will do), hopefully get a couple of recommendations for installers the guys and gals on here have used and who'll quote sensibly.2 kWp SEbE , 2kWp SSW & 2.5kWp NWbW.....in sunny North Derbyshire17.7kWh Givenergy battery added(for the power hungry kids)0 -
OK Central Bristol
Got three local companies visiting
Our chimney is the culprit - though as you face the SE roof it is on the left side so whole roof is basking in sunshine currently - so any shading would be later in the day0 -
Oh and do Solar Edge Power Optimisers have to be used with a solar edge inverter? Or can they be used with say a Sunny Boy?0
