Solar4Ever Pricing Guide - Updated December 2019

Solar Prices (All prices shown include GST)

 

Solar panel prices

All costs shown are for ≈ 6.6kW of panels after deducting STCs.
e.g.
Jinko at the top of the table are $195 each, or $3900 for 20 (6.6kW)

Government discount is 100 STCs at current price of $36 = $3,600

Difference $3,900 - $3,600 = $300

So you pay $300 in total for 6.6kW of Jinkos if installed in 2020

Panels shown with a cost -($xxx) mean that the Goverment discount is greater than the cost of the panels.

Efficiency is directly related the the physical size of the solar panel.
All of the panels above are approximately 1.7m x 1m.
Longer panels (2m) are available but usually not recommended for residential installations unless it is possible to install additional support rails to avoid flexing in the wind that cause micro cracks in the panel cells.

ALL of the above panel models are made in China except REC (Singapore), LG (South Korea), Q.Cells DUO+ (South Korea), SolarWatt (Germany), and the SunPower Maxeon 2 (Malaysia).

All are mono celled panels using 'P' type cells except LG Neon2, REC NPeak and SunPower Maxeon 2 which have 'N' type mono cells. ('P' type cells typically degrade at 0.6% a year, 'N' type at 0.3%)

19 x 350W panels (TW Solar, Longi) = 6.65kW
20 x 330W panels (Jinko, Q.Cells, Risen, Leapton, LG, Seraphim) = 6.60kW

21 x 315W panels (REC, SolarWatt) = 6.615kW

22 x 300W panels (Canadian) = 6.60kW

20 x 320W panels (SunPower P19) = 6.40kW

18 x 360W panels (SunPower Maxeon 2) = 6.48kW

Click the blue Panel link to download datasheet/brochure.

REC NPeak and SunPower P19 are black on black, meaning they have a black frame and black backsheet. Seraphim datasheet does not show this, but they are.

Jinko, Q.Cells, Canadian, REC and LG have long established Australian office/warehouse/support operations.

Warranty shown is for manufacturing defects. Q.Cells, REC, LG and SunPower include labour to replace a faulty panel, the others do not. NREL report shows that failure rate on 30 year old panels is 1 in 1,000, so risk of failure is very low.

If you want to understand more about these panels and why you might choose one over another then please either call or email us (our details on Contact Us page) or else read our Products page.

Second hand/Used solar panels
As people upgrade their old systems we recover a lot of second hand panels.

We would prefer these end up doing some good in Africa and if used for that purpose then they are free, but if you just want to extend your existing system or need one or two for your, car, van, farm etc then they are $10. Click here

Phase
If your home has a three phase electricity meter, then you need a three phase inverter.

(or 2 x single phase, e.g. 2 x 2.5kW, or 3kW + 2kW). (SM) indicates this inverter supports a 'Smart Meter' for reporting on consumption as described further down this page

Warranty
5 year parts and labour, plus a bonus 5 years parts only is standard (that's what 5+5 above means). Huawei give 10 years parts AND labour as standard, with an extra 5 years parts and labour warranty for $300 or 20 years parts and labour for $600.

Hybrid (Battery)

Any of the above inverters marked 'No' in the Hybrid column cannot ever directly connect a battery for storage and night time use. They only manage the solar panels. A hybrid inverter does two jobs, managing the solar panels AND storing and releasing battery power. This is what is commonly called 'DC Coupling'.

If you buy a non hybrid inverter then you can buy a second inverter (sometimes hidden away inside the battery cabinet) that connects to your switchboard. This is called 'AC Coupling'.

If you buy a hybrid then you really have the best of both World's. You can choose to 'DC Couple' whichever batteries the hybrid is designed to work with now and in the future (new battery support is all achieved with firmware upgrades) , or else you can choose to 'AC Couple' something different like a Telsa Powerwall if that is a better fit for you, come the time.

Smart meters
In the list above those market with (SM) in the Phase column support an optional smart meter. These meters are installed in your switchboard typical with CTs clamped around your phase cable (s). They report in real-time the flow of electrical current in both directions so that the inverter can then produce a detailed analysis for you in the reporting software.

For example, in the picture below, in this case from a Huawei smart meter, we can see the red line is showing power bought from Synergy. The green line is the solar production and the blue line is self consumption of the solar in the house. The difference between the green and the blue is export. (Power sold back to Synergy for 7.135 cents per kWh FiT)

All prices are excluding installation and consumption (smart) meter, except Goodwe and Growatt who include the smart meter with their hybrids, and Tesla Powerwall 2 which includes their own inverter and smart meter.

Inverter "Smart Meters"

Measure and report on power consumption in the house, and with

hybrid inverters, are what the inverter uses to know when to store

surplus solar power in the batteries, or else release battery power.

They are also needed if 'export limiting' is required.
