Obtained this quote from a local installer. We have a modest three bedroomed single storey house with 3 X 12,000 btu and 2 X 18,000 btu dual inverter air conditioners. No electric vehicle. Panels to be installed upon carport roof. Meter will require moving to the next power pole and the mains will then enter the house from the opposite end. This is included in the quote. Looks good to me but if anyone can spot any errors or omissions I'd be obliged. Thank you most kindly!

Personally, with five air conditioners I would go considerably bigger. Probably around 18 panels, roughly 11 kW of solar, a 10 kW inverter and at least 16 kWh of battery. From there the sky is the limit, depending on how much independence from the grid you actually want.

I would also look closely at everything around the system, not only panels, inverter and battery. Proper breakers and safety breakers, surge protection, battery protection, correct cable sizes, and an overhaul of the existing electrical system in the house if needed.

The quote already includes quite a lot of this, including the distribution box, leakage and short circuit protection, battery breaker equipment, surge protection and grounding, which is good.

It is strange, once you first get a solar system you always seem to wish you had more. I oversized pretty much everything myself from the start, except the battery capacity, which I added to later on.

I cannot really comment on the price itself, because that depends a lot on the company doing the installation, factory guarantees, the quality of the components, and what the installer promises in terms of aftersales service.

I also think you need a bigger inverter etc.

You don't mention any brand names for inverter and battery.

Make sure you order reputable inverter and battery/ies.

For the submission of the documents, I heard (can't remember where, think it was my electrician) that for a 5kW system it was B5000, 10kW system B10000, 20kW system B20000. Not sure of any reason behind this, so your charge for this item seems high.
