3 main types of solar cells

There are 3 main types of solar cells.

Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Monocrystalline solar panels are also the most expensive.

Polycrystalline (or multi-crystalline) silicon produces the next most efficient type of solar cell and is the most popular choice as it provides an excellent balance of performance and economy. Recent improvements in polycrystalline panel technology are bringing these modules closer to monocrystalline in size, efficiency and heat tolerance characteristics. The European market has now adopted polycrystalline as the standard.

Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so.


In most situations, we recommend the use of quality polycrystalline solar panels for home solar power systems.
