4kW System in Welwyn Garden City - Hertfordshire

[grybaz]

As some of you may remember I had 470W DIY system installed in summer as pilot project and planned to get MCS approved install in Spring 2012.

I had some quotes for FITs sytem august/september, so it came very useful when government announced new tariffs. I swiftly managed to book next available slot with one of the local installers, without having to pay any Premiums.
So here it is, full blown 4kW system on my roof... from 28th of November

Looks good.

Photo 18 has the dreaded aerial shadow.  You will need to sort this out.

Does the dormer give afternoon shading?

Excellent

Well done for nipping in under the wire. Looks like you'll have shading issues there from the dormer and aerials (depending on azimuth). Enecsys micro-inverters might be worth the money in that case (I realise this info may be a bit late in the day).

Hi Guys, thanks for your responses....
Aerials give some shading up until around 9 AM in early morning. I will be repositioning then in coming weeks when weather is better on weekend.
The dormer does not shade panels at all
