Roof on the house is broadly south facing but has a dormer which limits the number of panels to 4, maybe 5, with a small amount of shading for a few hours a day.
Two to each side of the dormer, vertically, and one in front, horizontal.
We had already been considering a garden building at the bottom of our garden, 18'w by 10'd, again south facing.
Spoken to a local company and they're reasonably confident they could build one that could hold an array.
Building would be roughly 23 metres from the electricity meter in a mostly straight run and, ideally, we'd want the inverter/batteries/etc. in it.
(Very) rough sizing says we could fit potentially 5-8 panels on the building.
Five at the front, vertical alignment, with three behind in a horizontal alignment.
Would need some kind of risers as the building pent will be so small it might as well be considered a flat roof.
Depending on how they're laid out I suspect there may be a small amount of shading of the back panels in that configuration.
So questions are;
- Given the potential shading I'm guessing we would be best looking at DC optimizers or microinverters?
- We would need to run cable from the house array, either directly to the inverter or to the building array, and then a second cable run from the inverter back to the meter?
So (23m x 2) + ~9m (2.5 story and assuming it just goes down side of house) = 55m, 23m AC, 32 DC
So does that all look practicable and any obvious pitfalls or stoppers?
Have I got any assumptions obviously wrong?
Thanks.
