Here's our Solar PV Installation using 15 Sanyo HIT-H250-E01 and SolarEdge SE4000 in a 5-4-3-2-1 Pyramid configuration ! (3.75KWh)

Welcome and looking good - I think you mean 3.75 kWp (kWh = kilowatt hours & you have 250W x 15 = 3.75 kilowatt peak)

It looks a good neat installation. Did you specially choose the panels to match the roof slope or was it luck?
Any particular reason for all the connector boxes? I thought most panels have boxes on the back of them and leads to daisy chain from one to the next.

I think they're cleverer than just connector boxes. From the SolarEdge datasheet: A proprietary data monitoring receiver is integrated in the inverter
and aggregates SolarEdge PowerBox performance data from each
PV module.
It's not made overly obvious what they actually do, though. |

It's not made overly obvious what they actually do, though. The link from EccentricAnomaly is to the inverter but this link is probably the link for the black boxes: http://www.solaredge.com/groups/products/overviewIf the black boxes are power optimisers, I'm surprised that you need them. They are used in shaded situations to stop all panel generation being affected by shade on just one or two. You don't seem to have a shading problem unless the TV aerial is a problem, so I'm also asking why you need them. It may help if they give data monitoring for individual panels but most roof unshaded systems don't really need that. |

Thanks guys, we are also well impressed with the layout of the panels.
You are correct these are power optimisers, typically used for shading issues (which we do get from October through winter months due to neighbouring trees) it is a little overkill admittedly, but this coupled with the fact that each and every panel can be monitored for production of energy and that you can use this info over time to show panels efficiency losses (and compare with your panels warranty, how else can you do this?) and each panels MPP voltage is tracked separately, and this info is available via a web portal, for an additional £300 over SMA & Sunnybeam, really a no brainer for us!

Sorry to say but unless I am mistaken don't the Sanyo panels need vertical rails (2 rails spaced 70-90cm apart and so 35-45cm overhang on each side) when installed landscape in order to stay within the manufacturer's installation guidelines and so make their guarantee valid.
That is certainly how we would install them

Peter1919,
don't know what you mean by your statement can you please clarify?
The installation has been by a reputable MCS accredited installer, do you believe that the installation has not been done correctly? I would appreciate your feedback so that I can ask the installer themselves. Thanks.javascript:void(0);

The panels should not be installed on the short side, the panels as fitted will not be warrantied, they flex to much. this is of course unless they have changed the warranty and I have not seen it. Ask the install for the instalation document for the panles, it will be in there.
cheers
Jon

If the rails were installed vertically and the panels fixed as per picture No 4 here--- http://www.navitron.org.uk/forum/index.php/topic,15488.msg173406.html#msg173406would have save a lot of expensive rail ie half as much! as installed =48m of rail - (30x1.6m) as pic No 4 =24m of rail - (30x0.8m) |
