Solar panels.
The solar panels we favour for a 'standard ' panel are:
LonGi
JinKo
Canadian Solar
Leapton
Seraphim
Easy to source in Perth (not all panels are easy to get over here).
All the same quality, almost identical in every way.
World's largest brands (Tier 1 rated by BNEF).
100% reliable. Zero failures to date with any of them.
Free. The Government subsidy (STCs) zeros out the panel cost.
Warranty 12-15 years, but 99.9% likely to last 25+ years.
For a panel with a guarantee (warranty) of lasting 25 years.

All of the descriptions for standard panels apply for these premium models except the price.
Allow an extra $2,000 to $3,000 for an installation of these in your budget
Below are the most frequent questions people ask about 'Premium' priced panels.
Do premium panels make any more power?
A 6.6kW installation of Premium panels with 'N' type cells typically makes 50kWh extra a year, which is worth $2 to $15 a year depending on how you use that extra power.
Making more power isn't why people purchase premium panels, unless they don't know any better !
Do they look nicer?
Sometimes.
They often have an 'all black' look, where regular panels usually have just a black frame.
Do they handle shade better?
Some do it a bit better, but if you have shade, the solution isn't to be found inside a solar panel design.
Are they more corrosion resistant?
Not any more. The standard panels have raised their corrosion resistance to the same 'Level 6' protection.
Does Solar4Ever install many of these premium panels?
We install a fair amount but 80% to 90% of our installs are regular panels.

Solar Inverters
The solar inverter models we favour for a 'solar only ' inverter are:
Growatt X. Good quality and nice looks, for such a low cost inverter.
Goodwe MS. For 3 x roof orientations.
Delta H5A-222. Built-in consumption meter.
Huawei L1 & M1. Even if you don't want a battery, these are the best inverters.
The solar inverter models we favour for a 'solar + battery ' inverter are:
Huawei L1 and M1. Single and three phase battery inverters of impeccable quality.
Goodwe XH. Remarkably cheap battery inverter, some minor limitations.
Fronius Symo GEN24+. Three phase only and incredibly expensive, but superb.

Battery storage
The solar batteries we favour for direct (DC Coupled) connection to an inverter are:
Huawei Luna 5-30kWh battery exclusive for Huawei inverters.
Growatt 6kWh battery exclusive for Growatt SPH and XH inverters.
For adding (AC Coupled) a battery to an existing solar installation:
Tesla Powerwall 2 (includes additional inverter).
Replace existing inverter with Huawei inverter and add Huawei Luna battery
