Solar energy basics

What are the 3 types of solar energy?

There are three main types of residential solar electric power systems: grid inter-tied; grid inter-tied with battery backup; and off-grid. These three broad types vary in how closely connected they are to the traditional power utility infrastructure, known as the grid.

What are the 4 basic components of a photovoltaic solar power plant?

These include:

  • PV modules (groups of PV cells), which are commonly called PV panels;
  • One or more batteries;
  • A charge regulator or controller for a stand-alone system;
  • An inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required;
  • Wiring; and.
