With the demand for cleaner and renewable energy increasing, many businesses begin to take solar energy into consideration. Solar energy is the cleanest and most abundant renewable energy source available. It is captured by solar panels. The two mostly used solar panels are
polycrystalline silicon cell and
monocrystalline silicon cell. Which one is better?
Space Efficiency
Monocrystalline is generally more space efficient than polycrystalline.
One square meter of
monocrysatlline solar cells will generate around 190W.
One square meter of
polycrysatlline solar cells will generate around 180W.
Temperature Tolerance
Polycrystalline solar cells generally have a lower temperature coefficient than monocrystalline solar cells.
Lets say you have a 1kW of monocrystalline solar array on the same roof and side by side with a 1kW of polycrystalline array.
The monocrystalline array will be slightly smaller compared to the polycrystalline array as it is more space efficient.
However, the 1kW polycrystalline array will generally generate more electricity over the year when compared to the 1kW monocrystalline solar array because of its better temperature tolerance.
Cost
A monocrytalline solar cell usually costs more than a polycrystalline solar cell, however when assembled into a solar panel, the cost of the mono panel is roughly the same as the poly panel in $/Watt.
Aesthetics
A monocrysalline solar panel generally makes a nicer looking solar panel as it is black in color where polycrystalline is dark blue in color.
However, the color of polycrystalline cells has darkened significantly the past few years and it is now looking a lot darker than it used to.
By now you should have known how to choose your ideal solar cells. Then how to form the solar cell into the desired shape?
SINOPOLY TECHNOLGY provides a great solution. The diamond multi-wire saw manufactured by us can cut the solar cells efficiently and at much lower cost. If you have any question regarding the diamond multi-wire saw, please give us a call at (86)1065535731 or email our sales at lyn@sinopolytech.com
