Morning all.

I finally got another quote ………… somebody actually came round to look at my house this time 😊

 

He gave me 2 quotes, one with and one without battery (so I can export the lot and use the grid as my battery)

 

14 x trina solar vertex s 400w panels

Givernergy hybrid inverter

8.2 kwh givenergy battery

 

With the battery was £10,500 …….. without the battery was £7,000

 

I do not know if this incudes scaffolding.

 

Thank you for any advice given

If it includes scaffolding then the price is about right.
My criticism would be why is it an 8.2kWh battery and not the new gen2 9.5kWh battery. In addition is it a gen1 or gen2 inverter?

I'm not sure if I shared this in your previous post but Trina panels are budget Chinese brand. My supplier installs 10X Sharp 400W panels + SolarEdge Optimizers + Inverter w/ 25 year warranty for under £6K.

This is the spec I recommend for most no matter who you decide on. No battery - just save the money upfront and sell excess to the grid. 

Here's a pic of a family member's home done in this spec just this week.

I'm just waiting for your supplier to contact me

Aren't they too close to the ridge sorry, hip? Wind loading from behind could exceed the rated strength of the panels and/or fixings?

I think  I am going to get upset with you QrizB. :-:smile: 

You beat me to post  a  very similar comment!...again.

I wondered why not further  across and higher  up the roof.

Maybe a reason we are not aware of.......

Positioned a bit low? If they were higher up the roof they could have been set further from the ridge.

Is the pic is taken in the evening with sun in the west? Panels fixed that low might get shading in winter from the roof to the right during the earlier part of the day

Panels have optimizers for the morning partial shading (from the roof to the right) during the winter months. The panels on the left will not be affected by any shade and will more than cover 8-11am consumption.

Sadly, the roof layout would not allow for higher positioning - that is concealed from view in the image.
