I’ve received a quote for 8 x Trina Vertex S+ 415w panels, 8 x Solar Edge optimisers and a Solar Edge 3.6kw inverter. I’ve priced these at Midsummer and it comes to £3000. The quote, excluding scaffolding, is £7400. Scaffolding quoted at £800. Additionally, the 10kw/h Solar Edge battery was...

Many inverters have an output for backup loads in the event of a power failure. How does this work? Is it literally a cable going from the inverter into the relevant consumer unit way - eg downstairs/upstairs lights? Ta all.

This is a diagram of what our ten panel will look like on the roof. The four panels on the right in blue are shaded till about 9.30am by the neighbours house. The sun moves right to left so panels 4 and 9 will clear first and then 5 and 10. The orange line shows shading from the chimney in...

Could somebody with more expertise than me look at this please. Attached shows the specs for both the GivEnergy 3.6 and their 5kw inverters. I was thinking that although our array will only be 4kw, should I go for the 5kw inverter rather than the 3.6, in order to make better use of the battery...

I knew our chimney might have affected one or two panels later in the day, but I thought I’d check. It seems by “one or two” I meant “five or six” 😂

So, just when I think I‘ve sussed everything about solar and battery storage, o hit another “ah but…” Assume battery has charged from solar during the day. Battery starts discharging as the sun goes down. At 8.30pm we start our Octopus Go Faster five hour cheaper electricity period. I realise...

As I think I’ve said on previous posts, we’re looking at a 10 panel system but 4 panels will be in shade from a neighbouring property till about 9.30am. The installer has suggested a GivEnergy inverter which has two MPPTs. My logic says (excluding optimisers for now) to put 6 panels into one...

Hmm. I checked the spec of our TV. It lists 0.5w in standby as you suggested. So plugged TV into TP!ink energy monitoring socket and switched the socket on, putting the TV into standby. Checked the TPlink app and sure enough it was reading 0.51w. So why did I think it was higher than this, I...

Thought I'd start a new thread as my last one was more about quotes. This is hurting my head. I know I really want solar but just not sure if I can make it work financially. We use about 9kw/h per day. Picking some arbitrary time blocks for a typical day it looks like this: 1.30am-9.00am -...

EDITED BECAUSE SINCE I FIRST POSTED THIS ANOTHER INSTALLER HAS GOT BACK TO ME First, thanks to all the experts who contribute to these discussions; I only found this site recently but already have learned loads. I'm considering solar and battery storage. We use on average about 9kw/h of...
