The solar panels monocrystalline and polycrystalline are both important.
Monocrystalline versus polychrystaline solar panel.
You would need a much larger array of polycrystalline panels to produce the same amount of energy than if you used monocrystalline which may not work for households with limited roof space.
Polycrystalline solar panels generally have lower efficiencies than monocrystalline options but their advantage is a lower price point.
Monocrystalline solar panel manufacturers will usually offer a 25 year warranty because of the longer lifespan of the product.
In addition polycrystalline solar panels tend to have a blue hue instead of the black hue of monocrystalline panels.
The price of a monocrystalline panel ranges from 200 to 300 which mainly depends on the quality and size of a solar panel.
This crystal structure makes the efficiency rate of polycrystalline panels lower than monocrystalline panels.
However polycrystalline solar panels are relatively cheaper than monocrystalline panels.
On this parameter of lifespan polycrystalline solar panels are not very different but the warranty period offered by the manufacturers may vary.
Polycrystalline solar panels are also made from silicon.
Monocrystalline solar panels comprise of silicon as a single crystal.
Polycrystalline panels have about 13 to 16 efficiency while monocrystalline panels have an efficiency rate of anywhere from 15 to 20.
On the other hand polycrystalline panels are included in many fragments of silicon melted together.
Depending on the size and quality of a solar panel the price of polycrystalline panels ranges from 60 to 90.
