I explained in my previous post “Why the efficiency of the solar panel is limited?”. It is true that solar cell responds to certain wavelengths of light that is from red to the violet region (visible region) of the electromagnetic spectrum of the light.
Sun is the greatest source of energy for the earth. During day, it is emanating enormous amount of energy in to our solar system. But we receive very small quantity of that energy on the surface of the earth, it is either reflected back or absorbed by the atmosphere while reaching to the surface of the earth.
The term efficiency tells the proportion of output to that of input. The more the proportion, the higher is the output. The opposite of efficiency is the term “inefficiency”, meaning comparatively less output than desired to that of input.
Going solar is one of the good decisions of your life and you will always want to foresee your lifestyle after going solar. The implementation of the solar system by you will not only help financially but also help in reducing the carbon footprints in the environment.
You must have noticed that the color of the solar panels is generally blue. The function of the solar panel is to absorb the sunlight and convert it into the electric current. The more it absorbs the sunlight, the more it produces the electric current.
We all use the electrical appliances like fans, lights, a/c etc in our homes, offices, and the public places as per our convenience. It is summer time in India and May-June are too hot to live without air coolers or the air conditioners.
We learned about the wiring of the solar panels in the series combination. It explained that in the series combination, the nominal voltage adds up while the current in the system remains the same. Now, we will see the effect on voltage and current when panels are connected in parallel.
You are sitting in your room and planning to fulfill your energy needs through solar power. After finding the solar roof feasibility, you decide to size the solar panels by calculating the daily electricity demand of your house and come to know that it is, say 3 KW per day. But there is no single panel in the
Our country India is located in the Northern hemisphere closer to the equator. In order to get maximum sunshine or the solar insolation, the solar panels should be placed southwards. For countries located in the Southern Hemisphere like Australia, the solar panels should face in the north direction in order to get the optimum sunshine.
