Understanding of Solar
Solar electric systems are composed of four critical components; Solar Panels, Charge Controllers, Batteries and Inverters. These components are necessary to have a Solar Electric (PV) system that functions efficiently.
Solar Panels
Solar panels are the main components of the system. The solar panels charge the batteries. Several solar panels wired together create what is called a solar array. The overall size of the solar array will determine...[more]
Charge Controllers
Although charge controllers come in many different sizes and types, they all perform a similar function. Charge controllers prevent the solar panel or array from overcharging the battery(s).

Batteries store energy for solar electric systems. Batteries play the role of storing the energy your solar panels produce during the day. Batteries will provide you with the energy you need at night...[more]
The last major component is the Inverter. The inverter converts the DC energy stored in your batteries and turns it into the AC power you use in your home. Inverters are rated by wattage and the quality of their output...[more]
A Little History
The word solar is derived from the Roman word Sol (the god of the sun), therefore, the word solar refers to the sun meaning solar power is power from the sun. When we say something is solar powered, we mean that the energy it uses was converted directly from solar...[more]
Photoelectric Effect and Quantum Mechanics
The photoelectric effect and quantum mechanics resulting in present day photovoltaic and solar cells were first studied by Albert Einstein in the early 20th century. Einstein observed that when light hit a metal surface an electric current could be observed.

The world's first solar power collector was built by Horace de Saussare, a Swiss scientist.
Solar cells were developed in the 1950 and 1960 for the space program as an ideal power source for satellites, but were too costly for general use...[more]
