Solar panel is the most important components in solar system, which transfer the energy sunlight directly into DC electricity.
60 Full cells mono Panel
The solar cells Type is Mono and 60 pieces of Full cells is Used to string together.
120 half cut cells mono Panels
60 pieces of cells are cut to half for 120 pieces of half cut cells ,and the solar cell type is Mono, and string 60 pieces of cells tighter to make 2 strings on a panel.
The above 2 type of panel we generally class them to small size panel and mainly used for residential roof case in australia, and we can also use Multi solar cells to replace the mono cells in side, but currently that is not popular in Australia, so we won’t list it here.
144 half cut cells mono panels
72 pieces of mono solar cells are cut into 144 pieces and string 72 pieces of half cut cells together to group a string, as a result, in a single panels we will get 2 of 72-cell string.
72 Full cells Mono Solar panel
72 pieces of solar cell are string together to make a single solar panel.
The above 2 type of solar panel have bigger size and weight, generally we used them for commercial case, we can also use Multi cells to replace mono solar cells, but Multi cells currently are not popular in our industry, so I won’t list it here.
And in Australia you are possible to see singled panel (overlapped design) and other special solar panels which we won’t offer in the market, you can google more knowledge by “singled Solar panel” or “sunpower solar panel” or “LG Solar panel” or “Dual Glass Solar Panel” or “HTJ Solar panel” .
For every type of Solar panel from different Brand, you can get a documents named Data Sheet, in Australia some basic information is very important and you will be frequent asked by your customer, you need always to keep that in your mind.
ModelName： for example F2M330H7A is one of model name in this serials this is very important you need to use everyday.
Performance: for example 330 =330W this tell you this panel ‘s performance is 330W, you also need to use every day.
Dimension and Weight: every day you need to explain to you customer
Connector Type : so you can exactly know how to connect your panel with other component.
Warranty: how many year warranty, for example, from this data sheet we offer 12-year product warranty and 25-year performance warranty.
you know all these information, you can start to work, and I am sure 99% of your customer are only know these information.
Package information, and original production country, you also need pay attention.
You can always get data sheet from our website

Inverter is another very important component for the solar system, it is used for transfer DC generated by panel to AC, as a result, it can be used to power your home or just feed-in grid.
Generally we need pair the Solar panel performance and Inverter performance , for example if I install 5KW totally solar panel on my roof, I need a inverter of 5KW to mach solar panel output, but generally the output performance of solar system are not stable because sun light are always out of control of us, based our experience, generally Inverter performance *1.3 should mach solar panel out put performance. for example, in Australia, we generally mach a 5KW inverter by 6.6KW solar panels.
|Performance||How many kW you can get from model generally|
|Model Type||very important, you will be asked every day.|
|MPPT||2 MPPT mean you can put panel in 2 directions|
|String in one MPPT||2 String, mean you can install 2 string of panel in the same direction.|
|Phase||Single Phase for 220V residential solar system, and 3 phase for 380V commercial solar system|
|DC isolator include||if DC isolator doesn’t included, we need to suggest installer to install DC isolator by themselves , otherwise, don’t need to install DC isolator separately.|
|Warranty||Generally 5+5 stand for 5-year free replacement with labor and extra 5-year component free without Labor, and 10-year Full warranty.|
|Fronius||Premier, expensive, but lots of Australian want to use, Euro Brand.|
|Solar edge||Premier Expensive, Euro Brand|

|Solise||Massive Inverter, Cheep, acceptable in Australia, best 5 brand in China|
|SAJ||not popular, best 5 brands in China|
|Apsystems||Micro inverter(one -four panels used one inverter), premier but very expensive, not popular in Australia.|
battery is used for saving extra energy from solar system or from grid when the electricity rate is very low (specially in the mid night), to make sure battery can work together with your solar system, and grid net work, we need a Hybrid inverter, please see inverter paragraph for detail.
3 cases to use battery:
for us, please see website for battery.
Mounting system include Rails and Mounting Kits and other possible components, used to mount solar panel on roof
our target price will be challenged by customer for rail, you can use the difference of W/M and Anodisation process to challenge you customer make your professional.
Tin KIT is a collection of Mounting components that are popular for Tin roof.
Tin kit generally include : L-Feet, End Clamps, Mid-Clamps, Earth Cable Lug and Earth Clips. please check detail from website.
Tile Kit is collection of Mounting components for Tile roof like this picture,
include generally Tile-Hook, End Clamps, Mid Clamps,, earth cable lug, earth clips and others please check from our website for detail
Tilt Kit is collections so mounting components for roof we need an angle like the right picture.
include generally Tile Legs, End Clamps, Mid Clamps, Earth Cable Lug, Earth Clips and others, please visit website for detail.
for Mounting system, the above Rail and Kits are most popular for regular solar system, we generally offer rails and kits based on panel quantity and roof type:
2 Panes we need to offer 1 rail,
6 panels we Need to offer one 1.5KW KIT or one 6-panel kit
8 panels we need to offer one 2kw Kits or/one 8-panel KIT.
Generally the above mounting components are enough for a solar system, but occasionally your customers are possible to book more L-Feet, TILE Hook and Clip Locker 406/700 accordingly, please visit website for detail.
if you have been familiar with all these mounting staffs, you can finish 99% of residential cases by yourself, for other complicated case, i can train you case by case.
for a solar system, generally we need DC Isolator and Cover , AC isolator, AC Breaker, and Label kits, we can offer customer one by one, we can also group a kit if customer need regular solar system, for example 6.6KW.
Dc isolator is used to switch on / of DC for safe operation. generally for a string of solar panel, we need to install one near the panel string, and another one near inverter, and because the one near panel we need to install it on the roof, we need use a Cover on the isolator.
For 6.6KW system, generally we have 2 strings of solar panel, so we need 2 DC isolator and 2 cover on the roof. and 2 DC isolators near inverter(if inverter have no DC isolator inside)
For residential, generally we use 1000V DC isolator 1p, 2p, 3p, 4p is the same.
For commercial generally we use 1200V DC Isolator 1p, 2p, 3p, 4p, is the same.
AC Isolator and AC
AC Isolator is used to switch on/off AC for safe operation, we need to install one piece of AC Isolator on AC side of Inverter.
no matter how many string of DC for residential, after inverting, it will be integrated into one-way AC, so we only need 1 AC Isolator near the inverter.
for residential we need use 240V Isolator, and for comercial we need to use 380-440V isolator.
AC breaker in stalled in the electrical control box. one piece for one system.
for single phase, we generally use 1p 25A, 1p 32A, for 3 phase, we generally use 3 port 25A and 3p 32A.
We have other electrical products like DC cables 4D and 6D and switch locker or switch dog, that won’t be used in a solar system, and the customers are always electricians , I won’t list them here.
and for the above electrics, we are used to group them for a KIT for regular solar system as:
4 DC Isolators+2 DC isolator cover+1 AC isolator + 1 AC breaker+ 1 Label KIT.
