Solar panels - or solar roof ?

[bmj1]

Roof measures 10m x 14.5m, but lots of rooflights + dormers + angled bits.

 

Flat roof area measures 4.7m x 9.3m (subtract 1.5m x 1.5m and 1m x 1m rooflights) = ~40m² flat roof

 

Location: London

 

We have a 3-phase power supply to the house.

 

1. Should I be looking at solar panels ? If so - I suspect we want to use the flat roof only (for best visuals), and so want quite an efficient product, any recommendations ? Should we fit the panels now (while scaffolding is up), or better to wait a year, is the tech improving/costs coming down ?
2. Or solar roof? E.g. Solecco ?

 

I'm guestimating our electricity usage to be 7000kwh - 8000kwh / year.

 

Our roof structure should start to go up in around 8-10 weeks time.

 

Any advice or considerations gratefully received, thank you in advance.
