I sent out a few quotes and have had a number of calls infroming me that I am out by around R50 - R70 000.

One customer submitted my quote for the bank to apply to finace the installation. The bank offered an approved installers quote (R180 000.00) at R70 000 cheaper than my quote.

The quote is to supply and install Sunsynk 8 kva, 2 5.1 kwh Sunsynk batteries and 10 x 545 watt panels. AC bypass panels, DC combiner box for 2 strings.

including indentifying all the circuits and marking them, the COC and the cost to split the DB, the return visits and monitoring to optimise the system, if required.

Excluding SSEG registration and original COC for the existing electrical installation.

The rule of thumb at the moment is if you quote is less than R250 000, there is a good chance you going to be paying extra for item not listed in the quote
