solar energy panels

Solar energy - or power produced by the sun - is a huge and inexhaustible resource. The fuel the sun produces, once converted by some system into energy, is free and isn't subject to the fluctuation of energy markets. Solar power produces no emissions, and so is a clean alternative to fossil fuels. Because solar energy is so abundant for most places on earth, it offers a unique opportunity to play a prominent role in our energy needs.

A solar cells is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. It is a form of photoelectric cell which, when exposed to light, can generate and support an electric current without being attached to any external voltage source.

Why a charge controllers is necessary

Since the brighter the sunlight, the more voltage the solar cells produce, the excessive voltage could damage the batteries. A charge controllers is used to maintain the proper charging voltage on the batteries. As the input voltage from the solar array rises, the charge controllers regulates the charge to the batteries preventing any over charging.

A power inverters , is an electrical power converter that changes direct current to alternating current the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.
