If you want to build your own solar panels and get the most out from it, then this article will guide you on the most important aspect of solar panels. Knowing this will greatly affect the power efficiency of your panels.
Well, building your own solar panels might not be difficult with the right tools and step by step guide but building solar energy panels that last long, durable and provide the best saving in long term will requires this vital knowledge. Okay, it's actually about choosing the right panels for your home.
There are generally 2 types of solar panels:
(1) Flat Plate Technology or Solar Thermal - This type of solar panel system uses sunrays to heat up water.
(2) PV Technology or Photovoltaic - This type uses sunlight to create electricity directly.
We are focusing on the latter where we want to use the sunlight to create electricity directly. The PV Technology or Photovoltaic can further be classified into 3 types. I will share with you their benefits and drawbacks to give you the best of information so that you can build your own solar panels that give the highest power efficiency.
Monocrystalline Panels - this is the most widely used solar panel worldwide and it is also the most efficient. Monocrystalline Solar Panels are extremely sensitive that it can still perform in cool condition. It also has the highest power to size ratio meaning that you can produce about 130 to 180 watts of energy per M2. Hence, you don't need large space for this to operate but still get the best electrical conversion efficiency. However, Monocrystalline Solar Panels is also the most expensive of all but you can expect long life span of these panels.
Polycrystalline Panels - this is the second runner up to Monocrystalline Solar Panel but sill able to produce remarkable power efficiency at about 120 to 130 Watts per M2. It is also very popular because it is less expensive and has the same quality and durability as Monocrystalline Solar Panel. However, you might need a larger space to get optimum results.
Amorphous Panels - these panels consist of molten silicon that looks like thin film and spread across over a large plate of stainless steel or similar material. The power efficiency is lower about 60 to 80 watts per M2 and therefore you might need larger space to produce higher watts. The benefits on the other hand are that Amorphous solar panels are the cheapest and that it can continues to operate even if part of the panel cells are in shadow which the above two will not.
