Specifying batteries, pv solar etc using ChatGPT
I thought I'd try to use ChatGPT to specify my requirements. Based on
- West facing extension flat roof. 8.5m x 5.5m
- Shaded by main building no other shading
- 9kw ashp
- EV provision via zappi
- PV solar + batteries
- EPS preferably whole home, automated changeover.
- Zappi not part of EPS setup.
- Integration with Octopus tariffs
Pretty good initial suggestions I feel:

Comparison Table: https://chatgpt.com/s/t_68b7345032188191901a20142eb8177c
Any thoughts/comments? Briefing requirements OK?
Listed Grade 2 building with large modern extension.
LG Therma V 16kw ASHP
Underfloor heating + Rads
8.7kw pv solar
3 x 8.2kw GivEnergy batteries
1 x GivEnergy Gen1 hybrid 5.0kw inverter
Manual changeover EPS
MG4 EV
I have been positively surprised when I asked it to specify a PV system for a flat roof and mentioned I was interested to do something so it does not get dirt from birds sitting at the top! It started giving some suggestions of systems, asking if there is a parapet or not in the roof.
A lot of the base information of pv cells and inverters seems to have been updated by manufacturers, specifiers, etc and so chatgpt does a very good job at working out what is most suitable.
The info about birds and other aspects like chimneys etc, it probably figured out from what people generally ask in forums or questions from websites where people input their queries..
