Converting Sunlight to Electricity

How Solar Panel Works?

Solar panels work through what is called a photovoltaic process where radiation energy (photo) is absorbed and generates electricity (voltaic).

Radiation energy is absorbed by semi conductor cells, normally silicon and transformed from photo energy (light) into voltaic (electrical current).

When the sun's radiation hits a silicon atom, a photon of light energy is absorbed, knocking off an electron.

These released electrons create an electric current. The electric current then goes to an inverter, which converts the current from DC (direct current) to AC (alternating current). The system is then connected to the mains power or electricity grid.

Components & Equipments

Installation of solar panel involved construction of racks and various components. In ideal solar panel system, the whole system contains the following components

• Solar Panels & Inverter
• Switch Board & Electricity meter
• Electricity main grid (TNB)

Solar Power Cycle

Solar Electric System
Energy is converted into electricity from your building.

Net Metering
Energy you don't use is credited to you as it passes through your utility meter and into the utility grid.

Time of Use Metering
Time-of-use metering allows you to "sell" electricity at higher rate than you use.

A solar energy system

• Provides free energy and gain pay off from TNB
• Creates a hedge against electric cost inflation of nearly 7% per year
• Increases the value of your premise (home, factories, building, etc.)
• Is good for the environment by producing no pollution
