Ideal for remote locations and independent energy needs, they offer durability and long-term performance. Easy to install and maintain, these panels provide a sustainable and cost-effective solution for renewable energy.
Product Features:
1) High photoelectric conversion efficiency:
The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, with the highest reaching 24%, which is currently the highest photoelectric conversion efficiency among all types of solar cells.
2)Low production cost:
The production cost of monocrystalline silicon solar cells is relatively low, and the technology is already very mature, so it has been widely used.
3)Long service life:
The service life of monocrystalline silicon solar cells is relatively long, generally reaching around 20 years, with the highest reaching 25 years.
4)Good low light performance:
Monocrystalline silicon solar cells can also perform well under low light conditions, making them suitable for use in solar lamps, solar lawn lamps, etc.
5)Strong radiation resistance:
Monocrystalline silicon solar cells have strong radiation resistance, which can resist radiation such as ultraviolet and infrared rays.
