What do you associate Energy with? When you think of it, you might be thinking about coal or oil or natural gas. These energies originate from the earth which we refer to them as fossil fuels. These fuels have existed for decades to fuel, our homes, cars and much more. However, did you know that there is a far better way to obtain energy that does not harm our planet? That special type of energy is known as solar energy, and simply put it comes from the sun!
The sun is a truly incredible and powerful energy source. It emits light and heat that we can harness. This energy can best be utilized in the form of solar cells. Composed of special materials that convert sunlight to electrical energy, solar cells are the basic building blocks of the technology. Solar panels are made by combining a lot of solar cells. They can be used to power our homes, buildings and even vehicles so they play a significant role in clean energy generation.
The performance of solar cells depends heavily on the materials from which they are made. The majority of solar cells are produced from a substance known as silicon. And silicon is a semiconductor. This means that semiconductors can conduct electricity in some cases, but not others. This property is what makes them ideal for solar energy capture because they can convert light into electrical power, all without emission to the environment. Solar energy can assist us to keep our air unpolluted and our planet healthy.
After collecting solar energy from the sun, solar cells convert them to usable electricity in houses and buildings. Going through a process called inversion helps achieve this. Inversion the process of converting the direct current (DC) electricity generated by the solar cells into alternating current (AC) power. AC power — the electricity that powers our daily lives when we flip a light switch or plug in an appliance.
For this conversion, a dedicated device is used called an inverter. The inverter converts the DC electricity from your solar panels into AC electricity This alternating current electricity can then be used to run anything from lights to refrigerators in our home. This is an important process as it enables the solar panels to utilize the energy produced immediately or store it in batteries for use later, when sunlight is not available.
So researchers have been working around the clock in search of new methods for increasing solar cells productivity. The idea includes using some novel materials that can accumulate more sunlight with a wider spectrum than standard photovoltaic device can deliver. Some people have done it with solar cell styles that absorb much more deep in the infrared and work under much worse light, such as during cloudy days or winter. This suggests that it can make us utilize solar energy in a better way.
And for homeowners, solar panels can also save money energy bills. Homeowners who generate some of their own power use less grid electricity, avoiding pricey kWh costs. For some, this can be real $$$ in the long run! Beyond that, attractive solar panels will raise the value of a home and therefore make you smart for the future. Homeowners installing solar panels can reap the rewards of cheaper electricity bills and increased property values.
