The Working Principle of a Solar Cell In this chapter we present a very simple model of a solar cell. Many notions presented in this chapter will be new but nonetheless the general idea of how a solar cell works should be clear. All the aspects presented in this chapter will be discussed in greater detail in the following chapters.
According to the Off grid solar system working principle, the off-grid solar system is not connected to the power grid; instead, the energy produced by the sun''s rays during the day is stored in batteries. This approach is effective for residences that do not have access to the grid''s electricity and are thus entirely self-sufficient.
