Renewable resources – Solar Panels

Reading Time: 2 minutes

In today’s world, we already have five renewable resources biomass energy, hydropower, geothermal power, wind energy, and solar energy. I would like to focus on the one you can install even in your house: Solar Panels.

What are solar panels?

The simplest form of energy that can be obtained is solar energy. That is why solar panels were created. Photovoltaics is a process in which, thanks to its panels, we can obtain electricity from the sun. Solar panels are placed on the roof to collect energy from the sun and use it for free electricity.

How do they work?

The solar panels’ principle of working is that the photovoltaic cells that create the panels convert solar energy into electricity. A photon which is, the minimum unit of light falls on a silicon wafer that is a photovoltaic cell.

Why solar panels are good?

The most important thing about photovoltaics is that they are a renewable source of electricity and has no negative impact on the environment. Unlike fossil fuels, the sun creates much more energy than human needs.
Additionally, while using solar panels to generate electricity, no greenhouse gases emissions (carbon dioxide CO2) are released into the atmosphere.

The costs

Photovoltaic panels are costly. Of course, it all depends on how many panels you are planning to have, but they seem to decrease their price form year too another. However, once the solar panels are installed at someone’s property, they save a lot of money, because they do not use electricity from the powerhouse, but they are producing energy themselves. This means not paying electricity bills for the rest of your stay in this house.

To conclude, solar panels are desperately needed in our world. They are reducing CO2 emission and will not end anytime soon. They are expensive to install for a private person, but it gains profits after years, for not paying electricity bills. So I leave you with the question: Should we do solar panel installations in our homes our New Year’s resolution?
