Monocrystalline solar panels have the highest efficiency rates, and also have high life time vlaue.
Monocrystalline Solar Panels are made from a single continuous crystal structure a silicon crystal ‘seed’ is placed in a vat of molten silicon. The seed is then slowly drawn up with the molten silicon forming a solid crystal structure around the seed known as an ingot. The ingot of solid crystal silicon that is formed is then finely sliced ingot what is known as a silicon wafer. This is then made into a cell.
Monocrystalline Solar panels have Efficiency-Rate of up to 22% they are optimised for commercial use and have high life-time value.
Polycrystalline Solar panels have Efficiency-Rate of up to 19%.
Polycrystalline also start as a silicon crystal ‘seed’ placed in a vat of molten silicon. However, rather than draw the silicon crystal seed up as with Monocrystalline the vat of silicon is simply allowed to cool. This is what forms the distinctive edges and grains in the solar cell.
Polycrystalline cells were previously thought to be inferior to Monocrystalline because they were slightly less efficient, however, because of the cheaper method by which they can be produced coupled with only slightly lower efficiencies they have become the dominant technology on the residential solar panels market.
Polycrystalline Solar panels have Efficiency-Rate of up to 19%. Thay have Very affordable price with more demand in the market they are now the main streamed solar panels.
