When making a decision to install your own photovoltaic energy system, choosing the right photovoltaic solar panel for your home or business may seem like a daunting task. This is why Genergy has filtered through the many manufacturers in order to find the best photovoltaic panel from around the world in terms of Yield per Rand spent with the Yield under written by Chubb. What does this all mean?
There are three basic construction types of silicon cell photovoltaic panels: Monocrystalline, Polycrystalline, also known as Multicrystalline, and Amorphous. Monocrystalline photovoltaic cells are cut from a single silicon crystal, giving them a smooth appearance. They are rigid, requiring a rigid frame and glass to protect them. As the most efficient PV panel type, monocrystalline Photovoltaic panels are also the most expensive. While a mono crystalline Photovoltaic cell is a slice of a single silicon crystal, a polycrystalline, or Polystalline Photovoltaic cell is essentially a slice from a block of silicon containing many silicon crystals, exhibiting a speckled appearance. Still requiring a rigid frame, polycrystalline cells are less expensive, though also slightly less efficient, than monocrystalline cells. Amorphous photovoltaic cells employ non-crystalline, or amorphous, silicon in a thin film, coating one of many possible materials, including plastic and metal. It is the least expensive and least efficient of the three silicon photovoltaic solar panel options.
The most important aspect to consider when choosing your Photovoltaic panel options is between efficiency and cost per watt. The efficiency of a photovoltaic panel is based on the amount of energy produced in relation to the size of the panel. For example, if two Photovoltaic panels are the same size as each other, yet they produce different amounts of energy, the panel which produces more energy would be considered to have a higher efficiency rate than the panel with a lower energy output. Similarly, if two Photovoltaic panels are different sizes and produce the same amount of energy, the smaller panel would be more efficient than its larger counterpart, as the smaller panel does not require as much space or photovoltaic material.
Cost per watt should not be your most important decision based factor, the yield is what a buying decision should be based on.
