Crystalline (C-Si) solar modules are the mainstream products throughout the world, due to the stability of material supplies and maturity of production technologies. Solar cells are one of the most critical elements across the value chain because they convert sunlight into electricity. RITEK Corporation sources crystalline solar cells made in Taiwan only for our solar modules, in order to ensure the best quality. Our crystalline solar modules boast high efficiency, high reliability, high durability and low conversion lost. Meanwhile, we offer customized services to cater to a variety of customers’ needs.


 - High-quality components to ensure the best conversion efficiency 
 - High-level protection for tough environment
 - Warranty of minimal power output 90% at STC for 10 years
 - Warranty of minimal power output 80% at STC for 25 years


Solar Module Structure:

How Solar Power Works:

Solar cells utilize silicon as a semiconductor material. The cells are then assembled into a solar module that converts sunlight directly into electricity. When sunlight is absorbed by the silicon material, solar energy knocks the electrons free in the silicon crystal structure, allowing the electrons to flow through the silicon material to generate electricity. Converting light (photon) into electricity (voltage) is called the photovoltaic effect. Solar modules produce DC current that is converted into AC current when the solar system is connected to a house through a grid connection.
