the major part of that system is going to be “solar PV (photovoltaic) panels” (“solar panels”) that convert sunlight into electricity using a phenomenon called the photovoltaic effect.
There are 3 major types of solar PV technology:
Some think of monocrystalline solar panels as the ‘Rolls Royce’ of solar PV technology and the best choice. Monocrystalline is one of the oldest technologies, and more expensive to make, but this type have the highest efficiency.These solar panels can typically achieve 15-22% conversion efficiency in the real world, i.e. convert 16-21% of the sunlight that hits them into electricity. They are made from wine-bottle sized single crystals of ultra-pure silicon and sliced up like salami to make individual wafers.
These circular wafers have their sides cut square, and are then converted into a monocrystalline “solar cell” .
The silver lines are wires that collect the electricity that is created when light hits the cell. The solar panel is made up of a matrix of these monocrystalline solar cells laid flat – like tiles on your bathroom floor
Monocrystalline solar cells are generally high performance, but because they waste a bit of space between the cells when they are encapsulated in a solar PV panel (the little white diamonds in the picture above) they perform quite higher(in efficiency and power terms) as polycrystalline.
Polycrystalline solar panels are also made from silicon, but the type of silicon used is slightly less pure and they are cast into blocks rather than sawn from a single crystal. The fact that the crystals are randomly arranged means that they are visible individually.
Once the polycrystalline ingot is cast, it is sawn into square blocks and then sliced into square wafers that are processed to convert them into solar cells.
Here’s a close up of a polycrystalline solar cell – you can see that it looks very different to the sleek, uniform appearance of its monocrystalline rival:
The easy way to spot mono solar panels on a roof is to look for the tell tale white diamonds between the cells.
Polycrystalline solar cells are very similar to monocrystalline in performance and degradation, except in multicrystalline, the resulting cells are typically slightly less efficient. However, as you can see here, there is no wasted space between the corners of the perfectly square cells:
This means that when they are encapsulated in solar PV panels, there is slightly more area available to absorb sunlight. The result is that a polycrystalline solar panel’s performance is just a notchlower to monocrystalline solar panels due to their efficiency being a bit lower. Here’s what they’ll look like on your roof:
Whereas mono and polycrystalline solar panels are made in very similar ways, thin film solar panels use a completely different method of manufacturing. Instead of creating solar cells by sawing up large blocks of silicon, a film containing silicon is “sprayed” on to the surface that is to become a solar panel.
As mentioned above, thin film panels are basically obsolete in Australia, due to mono and poly panels far outstripping them in price and performance
When choosing between monocrystalline vs polycrystalline solar panels, despite what many salespeople will tell you, there is nothing really to distinguish between the types – except their looks!
However, as mentioned thin film panels are no longer available for the Australian residential solar market – so this technology choice is one you won’t have to make.
Only the first two technologies – monocrystalline and polycrystalline – are available in Australia these days. Thin film is no longer used here for residential solar panel installations.
