Is Solar Worth It in Black Mountain?
Black Mountain gets 5.2 peak sun hours per day — above the national average. A 6.6 kW system here would produce roughly 10,021 kWh per year, saving an estimated $1,378 annually and paying itself off in 3.5 years.
At $4,885 after rebates, the upfront cost represents 7% of Black Mountain's median household income ($74,672/year). Most households finance this over 3–5 years, with loan repayments typically offset by immediate savings.
Around 41% of dwellings in Black Mountain have solar, below the Queensland average of 42%. This means there's significant room for more installations — and early adopters tend to benefit most from current rebate levels before they taper off.
With a payback under 4 years and 20+ years of remaining system life, solar in Black Mountain is one of the stronger return-on-investment cases in Queensland. The question isn’t really whether solar is worth it here — it’s what size system to get.

How Solar Installation Works
Site Assessment and Quote
An installer visits your property, assesses your roof, checks shading, and provides a detailed quote based on your energy usage.
System Design and Approval
Your system is designed to maximise output. Council approval may be needed for heritage properties, but most residential installs are exempt.
Installation
A residential solar installation typically takes one day. The team mounts panels, installs the inverter, and connects the wiring.
Grid Connection and Meter
Your installer lodges paperwork with your distributor. Once approved, your meter is upgraded to a bi-directional meter and you start exporting.
