How Do Solar Panels Work

how do solar panels work

Simply, solar energy is the most plentiful energy source on the planet. At any given time, the Earth receives about 173,000 terawatts of solar energy, more than 10,000 times the world’s entire energy requirements.

Solar energy is a significant answer for tackling the present climate problem and reducing our reliance on fossil fuels by absorbing the sun’s energy and converting it to power for your home or company.

What Is The Working Principle Of Solar Energy?

Our sun is a nuclear reactor in the form of a natural object. It emits photons, which take roughly 8.5 minutes to travel 93 million miles from the sun to Earth. Enough photons hit our planet every hour to generate enough solar energy to meet the world’s energy demands for a year.

Photovoltaic power currently accounts for only 5% of total energy consumption in the United States. However, as solar technology advances and the cost of going solar falls, our ability to harness the sun’s vast energy reserves grows.

Solar Energy Transmission And Generation: The Fundamentals

1.  On the solar panels when the sun shines, an electric field is created.

2. The generated power flows to the panel’s edge, collected by a conductive wire.

3. The conductive cable transports the electricity to the inverter, which converts DC electricity into AC electricity used to power buildings.

4. The AC electricity is sent from the inverter to the property’s electric panel (also known as a breaker box), distributing the electricity as needed throughout the building.

5. Any electricity that is not consumed at the time of generation is channeled through the utility meter and into the electrical utility grid. The flow of electricity leads the meter to run backward, crediting your home for a surplus generation.

What Effects Does The Weather Have On Solar Power?

Weather conditions influence the amount of power produced by a solar system, but not in the way you may imagine.

A clear, sunny day is, of course, ideal for creating solar energy. However, like other electronics, solar panels are more efficient in the winter than in the summer. As a result, the board can produce more electricity in less time. The panel generates less voltage and produces less electricity as the temperature rises.

Although solar panels are more effective in cold weather, they do not necessarily produce more electricity in winter than in summer. During the summer, the weather is usually more pleasant. Aside from fewer clouds, the sun is frequently visible for a more extended period. So, even if your panels are less efficient in hot weather, they will almost certainly produce more electricity in the summer than in the winter.


While the science behind solar energy is complex, it doesn’t take a scientist to understand the advantages of solar energy to a business or property owner. An experienced solar developer can walk you through these advantages and assist you in determining whether a solar solution is appropriate for your company.
