Solar quotes vary significantly when pricing up the cost of going solar. This is because “solar panel cost” is too vague; it includes panels but also full system design (and yes, hardware around it), and then the complexity of fitting this piece onto your home safely.
1) Capacity point (kW) and coverage amount
Larger systems may have a greater upfront cost, but can also generate more power. That sweet spot will vary depending on your normal use case, whether you’re generally around during the day, and insulation levels in the house, if looking towards future demands.

2) Panel type and brand
The type of panels with different efficiencies, warranties, and low light performance should be kept in mind, especially when space is an issue, and only relative 20% of the cost per panel for premium panels with more power per panel may make sense.
3) Inverter choice
Solar panels are directly on the roof of your building, while an inverter transforms solar power into electricity that you can use. Prices differ based on whether you need:
A standard string inverter
Pricey microinverter (aids in shading)
A hybrid inverter (battery-ready)
4) Roof and installation complexity
If you have a steep, high roof that is difficult to get at or requires scaffolding, quotes can go up. If your roof has shading, multiple faces, or difficult cable paths, it might add to the labour time.
5) Battery storage (optional)
Granted, a battery isn’t cheap up front, but it’s yet another way to use more of your solar at home – particularly in the evenings.
6) Paperwork and compliance
It takes time to go through MCS certification, electrical testing, and setting up your exports into SEG eligibility (which is included within a pro quote).
Price is not the determining factor for finding a good quote, but rather getting one that fits your roof properly, in an itemised fashion to see where money goes, and even taking into account how you live!
