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.
Monocrystalline versus polychrystaline solar panel.
Monocrystalline solar panels comprise of silicon as a single crystal.
Polycrystalline solar panels are also made from silicon.
Polycrystalline panels have about 13 to 16 efficiency while monocrystalline panels have an efficiency rate of anywhere from 15 to 20.
In addition polycrystalline solar panels tend to have a blue hue instead of the black hue of monocrystalline panels.
The multiple silicon crystals in each solar cell makes it harder for electrons to flow.
Polycrystalline solar panels generally have lower efficiencies than monocrystalline options but their advantage is a lower price point.
On this parameter of lifespan polycrystalline solar panels are not very different but the warranty period offered by the manufacturers may vary.
The solar panels monocrystalline and polycrystalline are both important.
Polycrystalline panel efficiency ratings will typically range from 15 to 17.
Monocrystalline solar panel manufacturers will usually offer a 25 year warranty because of the longer lifespan of the product.
The price of a monocrystalline panel ranges from 200 to 300 which mainly depends on the quality and size of a solar panel.
However it is for you to decide on a good brand.
On the other hand polycrystalline panels are included in many fragments of silicon melted together.
