Most of the cost of solar is now the installation cost - ie. labour.
Roof solar uses a lot more labour, partly because roofs are inaccessible and need to seal, but also because roofs are smaller than fields.
A typical home solar install might take 3 guys a day to do - for maybe 6 kilowatts.
A typical field install can probably install 60 kilowatts with the same 3 guys in a day.
