Because monocrystalline solar cells are made of a single crystal of silicon, electrons are able to easily flow throughout the cell, increasing overall efficiency.
Monocrystalline solar panels have their manufacturing process to thank for being so efficient. The higher efficiency rating of monocrystalline panels makes them ideal for homes with limited roof space, as you’ll need fewer panels to generate the electricity you need. Solar panel type by performance Highest performance: MonocrystallineĮfficiency ratings of monocrystalline solar panels range from 17% to 22%, earning them the title of the most efficient solar panel type. Each of these materials creates a different ‘type’ of solar panel, however, they all fall under the thin film solar cell umbrella.ĭuring the manufacturing process, the photovoltaic substance forms a thin lightweight sheet that is, in some cases, flexible. Some of these photovoltaic substances include Amorphous silicon (a-Si), copper indium gallium selenide (CIGS), and cadmium telluride (CdTe). Thin film solar panels are made by depositing a thin layer of a photovoltaic substance onto a solid surface, like glass. Thin film solar cells are mostly used in large-scale utility and industrial solar installations because of their lower efficiency ratings. Polycrystalline panels used on residential homes usually contain 60 solar cells. However, the cooling process is different, which causes multiple crystals to form, as opposed to one. Similar to monocrystalline panels, polycrystalline panels are made of silicon solar cells.

Polycrystalline panels, sometimes referred to as ‘multicrystalline panels’, are popular among homeowners looking to install solar panels on a budget. PERC cells go through a different manufacturing and assembly process that increases the amount of electricity the cells can produce.īifacial solar panels, another monocrystalline technology, can generate electricity on both the front and back side of a module, and are gaining traction in commercial ground-mounted applications. Passivated Emitter and Rear Contact cells, more commonly referred to as PERC cells, are becoming an increasingly popular monocrystalline option. Nowadays, there are several varieties of monocrystalline solar panels on the market to choose from.
Fun fact! There is more than one type of monocrystalline solar panel This process forms a single silicon crystal, called an ingot, that is sliced into thin silicon wafers which are then used in the solar modules. Monocrystalline silicon solar cells are manufactured using something called the Czochralski method, in which a ‘seed’ crystal of silicon is placed into a molten vat of pure silicon at a high temperature. Monocrystalline solar panels are the most popular solar panels used in rooftop solar panel installations today. Three types of solar panels Monocrystalline
