2. Why the price moves around so much
Why it is so hard having a definitive price
There are so many factors in every single install, and most of them only become obvious once someone works through the site properly.
That is why variation in price is often driven by the actual install conditions, not just the hardware list on paper.
Common things that change the quote
Battery location in relation to the meterbox, meterbox upgrades, conduit needed, blackout protection work, materials used, roof layout and access, and trenching can all change the price materially.
The list goes on.
Some jobs can be worked up remotely, others cannot
It is easiest to have someone come to the job site and work out your needs and quote with you.
Some might offer to do it over the phone and email if you send a few essential photos across.
Typical variables to expect
These are some of the most common reasons final prices differ from one home to the next.
- • Battery location in relation to the meterbox
- • Meterbox upgrades to meet requirements
- • Conduit needed
- • Blackout protection work
- • Materials used
- • Roof layout and access
- • Trenching
Knowledge check
Why do two apparently similar homes still get different prices?
Because the site conditions, electrical work, access, materials, and battery layout can differ a lot once the install is planned properly.
Is a site visit always required?
Not always. Some installers can do a strong early pass by phone or email if you send enough useful photos, but many jobs still need a site check.
