There are three categories for Tier 1 rooftop solar panels.
Polycrystalline (Polys), typically 265W to 290W at $0.80 per watt
Monocrystalline (Monos), typically 300W to 330W at $0.95 per watt
"Premium" Monos, typically 360W+ starting at $1.30 per watt

Therefore if you were looking at getting 6.6kW of panels that would be...
6600W * $0.80/watt = $5,280 for Polys
6600W * $0.95/watt = $6,270 for Monos
and $8,580 + for Premium Monos

Then deduct the 'rebate' from the panel cost
If the STC price is $36 and you are installing 6.6kW of panels that is...
118 STCs @ $36 = $4248 of rebate in WA, QLD, SA, NSW
or
101 STCs @ $36 = $3636 of rebate in VIC and TAS

Tier 1 Polys
If you look up at other people's solar installations you will mostly see polys.
The frames are aluminium (silver) and the panels have a blueish colour.
Some of the most popular Tier 1 poly panels are...
Canadian, ET, GCL, Jinko,Talesun, & Trina
We would love to tell you that one is better than another, but the truth is that they are all absolutely identical. All very reliable, all long warranties, all same performance in heat, shade, same efficiency, same price...same same same.

Tier 1 Monos
Monos are black and often come with a black outer frame to enhance their good looks.
Monos perform slightly better in hotter conditions and therefore in Australia tend to produce slightly more power than polys. No more than a percent or two though. They are also more 'efficient' than polys, which simply means that they need less roof space to produce the same power.
e.g. You need 24 x 275W polys for 6,6kW, but only 22 x 300W monos. Q.Cells make a particularly good mono but it's pricey, next best and the World No.1 Mono manufacturer, Longi, are better value, and Trina make a good one too.

Solar Inverters

A "battery ready" inverter is a hybrid inverter, capable of handling both the solar panels as well as the battery. You know its a hybrid because you can see the battery input terminals on the underneath of the inverter. If it's not a hybrid, the inverter can not connect batteries...ever. However, that doesn't mean that your house cannot connect solar batteries, it just means you have to buy and install another inverter/converter that handles the batteries.

We explain battery readiness in more detail here.

Australia's most popular solar inverters.
Note. The price shown is as part of a new system. If just buying the inverter as a replacement, add on ~$250 for installation.

All the inverters listed below are 5kW models and include WIFI reporting to smartphone/browser. Click the blue links for Reviews/Datasheets.

* SolarEdge storage price includes 22 x P370 power optimisers
! There is also a hybrid version of Fronius Symo ($3900)
# This Sungrow model also has an additional 10A emergency circuit function

In the same price bracket as the Goodwe above are Sungrow, Zeversolar, Delta, Solax and Growatt and all are perfectly good inverters. Our preference leans more to Goodwe but any of these brands are fine. All of them, except Zeversolar provide some hybrid options in their range which you can read about on the review pages.

SMA have a similarly priced range to Fronius. They are all non hybrids as well.
Enphase manufacture an entirely different product, priced about the same as SolarEdge with inverters on the back of every panel and no central inverter.

Three phase

Most of Australia's energy companies allow you to connect a 5kW single phase inverter to a 3 phase home...in fact you can connect usually more than one giving you up to 15kW of inverter power (1 per phase). However, that's an expensive way of doing things compared to installing a three phase inverter, but it does allow you to have a hybrid. In WA the rules limit it to 3kW per phase maximum if using single phase inverters. So 3+2 or 3+3+3 is ok.

For those who scratch their heads trying to figure out how single phase inverters can be used successfully on 3 phase, please read this FAQ.

Power Optimisers

The main role of these $80 boxes connected to the back of a solar panel is to stop the lower current produced by a shaded panel from bringing down the much higher current of the rest of the string of up to 13 other panels it is connected to. We discuss this in detail here

SolarEdge require one of these to be fitted to EVERY panel, shaded or not, which is why the price for the SolarEdge inverter in the table above is so high. Huawei's optimisers can be selectively deployed where you need them, and Tigo optimisers can be fitted to panels running from any other brand of inverter.

 

Installation prices

Solar4Ever Electrical Contractor's Licence EC 13371

 

Installation prices vary across the country. In WA where we can zip across town pretty easily, costs are usually the lowest at about $100 a panel for a typical 24 panel job single storey single phase install. At the other end of the scale, Sydney installations are often closer to $160 a panel. Nationwide, an average of $130 per panel is pretty close.

 

It's not just location that makes a difference on cost, which is why you should ask us for an accurate quote. Here's why.

 

Let's say that your house is double storey, three phase and the panels are going on North, West and East and using optimisers on 10 of the panels to allow for the multiple roof orientations and shade. That's actually a pretty commonplace scenario.

 

All up, that scenario would add $700 to the install cost, and were aren't qouging ourselves a nice additional profit, that is simply a reflection of the additional labour and materials needed.

 

Solar Batteries

For any battery system to work, you need to have the inverter/battery system smart meter. This measures your power use in real time and informs the inverter as to whether to store surplus solar power in the batteries, or release it for use in the house. These meters should not be confused with a non hybrid smart meter (e.g. Fronius) whose only purpose is to provide data about your consumption but is redundant when you install a battery system.
Meters typically costs between $150 and $400 and $150 to install in the switchboard and wire back to the inverter.
