Solar panels have become a popular power generation option for homeowners. They help to reduce electricity bills and promote cleaner energy usage. However, have you ever wondered how solar roof panels work? In this article, we review the science behind solar panels and how they convert sunlight into electricity.
Solar Panel Composition
Before we dive into the details, let’s take a look at the basic composition of a solar panel.
Solar panels consist of photovoltaic (PV) cells, which are made up of a semiconductor material, usually silicon. PV cells transform sunlight into electricity with the aid of an electric field created by a pair of oppositely charged semiconductors.
How Do Solar Panels Work?
The sunlight photons contact the photovoltaic cells, and the material absorbs the light energy. The PV cells convert the absorbed sunlight into Direct Current Electricity (DC) via the electric field created by theo ppositely charged semiconductors. v
However, most homes use Alternating Current Electricity (AC). Thus, the DC current generated by solar panels gets converted into AC electricity through an inverter that converts DC into usable AC power for your home.
Factors That Influence Solar Panel Performance
Solar panel performance is influenced by various factors.
Firstly, Efficiency tells us how much sunlight energy the solar panels can convert into electrical energy. The more efficient the solar panels, the higher the electricity production.
Also, Solar panels are installed at specific angles to reduce the impact of shading from surrounding objects. Shading can lead to solar panels producing less electricity.
Temperature plays a significant role in solar panel performance too. Usually, solar panels perform better in cooler temperatures. High heat may damage solar panels, reducing their effectiveness.
Why Should You Consider Solar Panels?
Reduced utility bills are the primary advantage of solar panels. According to some estimates, solar panels can help you save about $1,500 each year in energy costs.
Other than reduced utility expenses, solar panels reduce our dependence on non-renewable energy sources and decrease CO2 emissions. Furthermore, solar panels increase the value of your property, making it more appealing to potential buyers.
