Solar Charge Controllers. Solar charge controllers are designed to do two primary things within a solar power system: optimize the charging of your deep cycle batteries by the solar panels and prevent electricity from the batteries from going through the solar panels when there is no sun.
The solar cell works in several steps: 1  Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon. 2  Electrons are excited from their current molecular/atomic orbital. 3  An array of solar cells converts solar energy into a usable amount of direct current (DC) electricity. An inverter can convert the power to alternating current (AC). The most commonly known solar cell is configured as a large-area pân junction made from silicon.
