Solar panel fitters were professional, however can't say that about the electrician who fitted the invertor as he was rude when he was told where we wanted it fitted. Didn't even clean up after he left. In addition, scaffold installation was outsourced to another company who did a terrible job. They erected the scaffold right up against the window which prevented us opening the window during the heatwave and the scaffold pole was right against the gutter down pipe which caused it to be out of shape. When I complained and sent photos to LMF about this, they took no action.
