Q? WHAT IS SOLAR ENERGY?
A. The Sun, like all stars, is able to create energy because it is essentially a massive fusion reaction. Scientists believe that this began when a huge cloud of gas and particles (i.e. a nebula) collapsed under the force of its own gravity – which is known as Nebula Theory. This not only created the big ball of light at the center of our Solar System, it also triggered a process whereby hydrogen began fusing to create energy. The process of nuclear fusion releases an incredible amount of energy in the form of light and heat, which is called as solar energy.
Q? WHAT ARE THE BENEFITS OF SOLAR POWER?
A. There are numerous benefits of solar power. Solar energy is not only sustainable, it is renewable and this means that we will never run out of it. It is about as natural a source of power as it is possible to generate electricity. The creation of solar energy requires little maintenance.
Q? HOW DOES A SOLAR CELL GENERATE ELECTRICITY?
Solar cells are generally made up of semiconductor materials. These materials have poor conductivity than metals, but they can still conduct electricity. When a semiconductor gets enough energy from an external source, it’s electrons get excited and jump to the conduction band, from where they are swept away.
Q? WHAT ARE THE TYPES OF SOLAR POWER PLANTS?
A. If we talk in terms of their functionality. Broadly speaking, they can be categorize into the following types:
- On-grid / Grid connected
- Direct load application.
Q? SUPPOSE IT’S A CLOUDY DAY OR A RAINY DAY. WOULD THE SOLAR POWER PLANT STILL GENERATE ELECTRICITY?
A. YES! It’s a common myth among people that solar power plant does not work in cloudy or rainy days. Whenever there is sun in the sky, the solar plant is going to produce electricity. Since all of the sun won’t be available for the solar power plant, it’s performance will be compromised by a small fraction.
