Please could those in the know give me a second opinion on my proposal for a 3 way split installation. This is my first install (my place) which I shall use for MSC verificatiion.
The bungalow has adjacent neighbours house due south so initially I opted for east west split. However after carrying out a shade survey. (sunpath charts attached, dam only south one uploading and top missing!) and learning of Solar edge power optimizers, I hope to fit 4 panels east, 3 on the very top of south facing roof (300 mm in from roof edge) 3 on the west facing roof.
The bungalow is 11' of south towards west hence opting for more panels on east facing. velux window and chimney allowing.

From the sunpath charts, which I compiled using a azimuth and elevation protractors, printed courtesy of university of Oregan of all places! This has to be adjusting for our latitude.. photo of said tool attached. I took readings on the roof at the base of proposed panel positions, recording the obstacles on the horizon I hope I am right in concluding the south roof to be mostly clear of shade from mid march which seems to make sense for the best part of the season. I hope that the shading that does occur should be acceptable using power optimizers. Although Doubling the price of the inverter my hope is using optimizers, the install will give more worthwhile outputs overall, compared to a more conventional two way split install using one or dual inverters, the latter being almost as expensive as the optimizers.
Please see attached photos of Bungalow, the East one indicates the proximity of neighbors house due south. although picture not very helpful, I am trying to get to grips with the free Google sketch up program which you should be able to produce a shade animation with, this may take some time. The Google earth picture is a good indication of bungalow orientation.South +11' west. This must have been taken in winter despite looking like a bright summers day, looking at the shading on my bunglow.
A bit of brain storming now does any one know of a resource that would give indication of ratio of light levels spread over the day. I heard that where we are On the coast, we tend to have clearer mornings, then when the sea has warmed up and starts evaporating the afternoons can cloud over, I have noticed this happening, Is the opposite phenomenon true the further inland you go? With this theory it is another reason for my place, to fit more solar east, together with the 11' leaning south.
Sorry for disparate nature of post and I hope there are some opinions out there, perhaps other Kooks may glean something from my experiences.
