PV Solar quote /5500kw annual consumption

A diy price from last week for comparison...5.7kwp, 4kw battery, 6kw hybrid inverter for 8.5k + a small bit for an electrician to do the forms.
 
A vote for mysolar, no connection.

Agree your quote seems high, BUT, I dont know if the market has taken the opportunity to up prices due to COVID inflation
