I had someone around yesterday to discuss installing a PV system for me, the discussion was mostly just an overview of technologies and different pricing such as loaning the roof and paying nothing, paying outright or paying with 5 years 0% finance.
I've done a bit of reading and know a bit more about what to ask about such as what panels, inverter etc. As my main roof is East facing the guy suggested putting a 4kw system on that roof section as well as installing an iBoost so that spare electricity goes to heating my hot water cylinder.
I've read that you are limited to 16amp without permission from the grid supplier, I was thinking that with my main roof section being east facing it would be good to put the main 4kw on that, but possibly installing an additional 1kw on the small south facing section of my roof (see attached picture)
If the inverter is limited to 16amp is it fine to have 5kw hooked up to it? It seems things start to get confusing at this point as I've read various accounts of FiT and G83 rules etc on whether its based on the peak power of the panels or the inverters output.
The guy estimated the 4kw system would be in the region of £7000 which until I know what he's installing is hard to judge on whether it's a good deal, but I know the prices have dropped quite a bit recently so it's possibly on the pricey side.
In an ideal world it would be nice to fill out the whole east, west and south roof sections as I could fit around 5kw on the east side and another 2.5kw on the south / west sections. But costs, planning permission, dealing with grid seems a hassle.
