Towards a greener life
Let the Sun Pay your Bills
You probably know that the plants get their energy from Sun through their leaves in a process called photosynthesis. We humans don’t have leaves, but we can get energy from Sun in a different way i.e. solar power.
Simply put, Solar Power is a power generation method that convert energy from the Sun into electricity. It uses solar panels that are often arranged on a building or concentrated in solar farms to facilitate a reaction that converts sun’s light radiation into electricity.
How do solar panels work?
Solar panels are made out of photovoltaic cells that convert the sun’s energy into electricity. These cells are sandwiched between layers of semi-conducting materials such as Silicone. Each layer has different electronic properties that energise when hit by photons from sunlight, creating an electric field. This is known as the photoelectric effect – and it’s this that creates the current needed to produce electricity.
Solar panels generate a direct current of electricity. This is then passed through an inverter to convert it into an alternating current, which can then be funnelled into the National Grid or used by the home or business the solar panels are attached to.
The Advantages
Solar power is the key to renewable, clean energy future. Solar power is also scalable. This means that it can be deployed on an industrial scale, or it can be used to power a single household. Extra electricity can be stored in a battery or fed back into the electricity grid. Overall, the sun gives off far more energy than we’ll ever need. The only limitation is our ability to convert it to electricity in a cost-effective way.
