Solar energy efficiency is one of the hot topics these days. There are many solar energy efficiency concerns in different segments of society like environmental issues, cost effectiveness and reliability. Energy efficiency plays a crucial role in any kind of technological advancement or project. It can either make us independent from the local utility company or it can reduce the cost of our monthly electricity bills.
How To Measure Solar Energy Efficiency?
There are three major ways in which solar energy efficiency is measured in a system like the solar energy efficiency measurement, the cost of electricity or the cost of installation. Solar energy efficiency is measured in kilowatt per hour (kWh) and this is used to measure the energy output by the solar power system. Solar energy is not easily available at night time, and thus solar energy storage is also an important topic in solar research. This is just one of the major research topics of this paper. Here I am going to discuss some of the major factors affecting solar energy efficiency.
Major Factors Affecting Solar Energy Efficiency
The first factor in solar energy efficiency is the heat energy that can be extracted from the photovoltaic cells using a special process called convective heating. There are many uses for heat energy in different sectors. This was first tested back in the 1960’s with the help of Gold nanoparticles.
The second factor is the efficiency of solar energy needs. The electrical current produced needs solar electricity, and heat energy is needed to convert this electrical current into thermal energy needed for illumination and warming up the room. These two energy needs need to be combined very well if we want to get the best results. There are many research projects at present all over the world trying to find ways to combine these two energy needs efficiently. Some of them are working very fine already.
Silicon Photovoltaic Cells
The third factor is silicon based solar efficiency. The silicon based PV cell actually uses the silicon in the photovoltaic cell. When silicon meets with light, its atoms will align, and then the electrons move freely and create electric current. In this case the light interacts with the electrons, which then creates an electric field. A good panel will have a module efficiency of around thirty percent.
Solar Heat Gain
The fourth factor, heat gain, is very important because it directly affects the electricity production cost. When the heat is taken out of the air by the solar energy collector, the cold air is then sent through the ventilation system into the room. When the hot air rises, it creates a huge amount of pressure in the pipes of the venting system. This creates a huge amount of power for the electricity production needs. High solar energy module efficiency of around twenty-five percent is required for the solar energy cost effectiveness.
These four factors are the most common and important criteria of solar energy cost. Other considerations, such as warranty, rebates, tax benefits, and the like, can also affect the final figure 1 cost. You should calculate your own based on the information above, but these are a few of the basics that you need to consider to make your own solar energy cost estimate. When you do you will be able to get an idea of how much power your home would produce for your needs.
In this day and age, using the sun’s energy for your renewable energy needs is a great way to save money. In addition, you are also doing your part for the environment. The fact is, the sun is here for everyone to utilize. With that being said, there is no better time than now to start using solar energy for your home’s electricity needs. Using a simple solar energy calculator is your first step in using solar energy. By finding the efficiency of solar energy, you will know if it is right for your home.
