Solar PV panels are a major component of solar power systems. The ‘PV’ refers to the photovoltaic effect, a process that converts sunlight into electric energy. The panels capture sunlight and transform into usable electricity.
Currently, there are three types of solar PV panels. These are:
#1 Monocrystalline Solar Panels
Although an old technology, monocrystalline solar panels are considered as one of the best. They are expensive to manufacture however they offer the best efficiency. This type of solar panel is made from pure silicon crystals that are sliced up thinly into circular wafers. Wires that look like silver lines run through these wafers. When sunlight hits each wafer and it is transformed into electricity, it is transmitted via these silver lines.
#2 Polycrystalline/Multicrystalline Solar Panels
This type of solar panel is made from slightly impure silicon than what is used to manufacture monocrystalline panels. Instead of forming from a single crystal, they are thrown into blocks. These crystals therefore get randomly arranged and are individually visible. When the polycrystalline slab is cast, it is cut into single square blocks. This is sliced into square wafers and further processed to be transformed into individual solar cells.
Polycrystalline cells are similar in performance and efficiency to monocrystalline cells.
#3 Thin Film Solar Panels
Thin film panels are manufactured using very different manufacturing methods compared to its mono and polycrystalline counterparts. Instead of cutting up large pieces of silicon into solar cells, a silicon-containing spray is coated onto a surface to transform it into a solar panel. The production procedures used to create thin film solar PV panels is more energy-efficient. Thin film solar panels have a shelf life of 20 years.
Thin film solar panels are much heavier than mono or polycrystalline panels. You need to have a very strong roof and capable installers installing them!
Switching your home’s energy requirements to solar power is both a wise and environmentally friendly decision. Not only are you reducing your carbon footprint, but you’re also taking advantage of savings on your next energy bill.
