Types of PV Solar Panels – Difference Between Poly and Mono Solar Panels
What Type of Solar Panels are Best ? Type of solar cell or PV (Photovoltaic) by Photo means light and Voltaic means voltage, the overall means of solar cells are divided into 2 major groups. There are the group of type silicon semiconductor type and non-silicon type. The details are as follows.
Silicon Semiconductor Type
This section is divided into two types.
1.1 Amorphous Silicon Solar Cells (Non-Crystalline Silicon Solar Cells)
Look like the thin film for example calculator and watch, Amorphous Silicon Solar Cell efficiency rated 6-10%. Usually less powerful than Poly Crystalline Silicon Solar Cells by power will be between the range 60-70 watts per square meter.
1.2 Crystalline Silicon Solar Cells (Crystal Silicon Solar Cells)
With the longer lifetime than the amorphous variety, there are two types.
Difference Between Mono and Poly Solar Panels
This is comparison of difference between poly and mono solar panels, details are as follows below.
1.2.1 Mono Crystalline Silicon Solar Cells (Single Crystal)
This efficiency of monocrystalline solar panels between range 18-25% rating. Generally have highest efficiency, the ratio of energy per unit area will be in the rang 135-170 watts per square meter.
1.2.2 Poly Crystalline Silicon Solar Cells
This type is purity less than Mono Crystalline Silicon Solar Cells but more than Amorphous Silicon Solar Cells. The sheets will be mixed with silver. Since there are also other minerals. this type of efficiency 12-15%. Usually have a good performance. The power will be in the range of 120-130 watts per square meter.
Non-silicon Semiconductor Solar Cells Type
More than 25% efficiency, this type to expensive and to used satellite and the other non-semiconductor type with doped silicon the various stages such as GaAs (Gallium Arsenide 35% of efficiency) and CdTe (Cadmium-Telluride 6-8% of efficiency, the current debate on the issue of harm to the environment). Efficiency 35% and expensive than other types.
Selection of Solar Panel
Mono Crystalline Silicon Solar Cells that have been most popular on the market. Reasons to choosing because the price and most cost-effective with very durable and lifetime of 25 years. But the current, Poly Crystalline Silicon Solar Cells has been developed to improve performance is the choice of implementation.
The invention of this power in the first phase investment is relatively high cost. But the profits and value in the future, within the next 5-7 years. Solar energy is free, clean and renewable energy to be used in our homes.
