Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many, smaller units called photovoltaic cells. … To work, photovoltaic cells need to establish an electric field.
What does solar energy need to work?
You’re likely most familiar with PV, which is utilized in solar panels. When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.
What are the conditions to generate solar energy?
Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom.

What are the functions of solar system?
The main thing to know about solar panels is that they absorb the sunlight and convert it into power that can be used for many different applications (street lighting, heating systems, machine installations, charging of phones, cameras, signage and many other energy driven devices).
Why is solar energy important?
Solar energy is energy derived from sunlight. Whether you realize it or not, the sun already powers our planet, providing the necessary energy to keep our environment and population growing. … Solar energy can be used to provide heat, light, and other electricity-dependent needs in homes and buildings.
How does solar energy help the environment?
The environmental benefit of solar energy
Solar energy creates clean, renewable power from the sun and benefits the environment. Alternatives to fossil fuels reduce carbon footprint at home and abroad, reducing greenhouse gases around the globe. Solar is known to have a favorable impact on the environment.
How effective is solar energy?
Most figures say that solar panels are roughly between 15% and 18% efficient, meaning that 15% to 18% of the sunlight they absorb is converted into electricity while the rest hits the solar panel and warms the surface like it would anything else.
Why solar is the best energy solution?
Solar energy is a good alternative to replace fossil fuel as the major energy source because solar power is renewable at absolutely no cost to supply energy with zero maintenance. Therefore, solar energy that is harmless to the environment will be the major energy source for future – starting today.

Who uses solar energy and for what purposes?
The most commonly used solar technologies for homes and businesses are solar photovoltaics for electricity, passive solar design for space heating and cooling, and solar water heating. Businesses and industry use solar technologies to diversify their energy sources, improve efficiency, and save money.
How does solar energy work for kids?
The sun shines on the solar panels, generating “DC” (Direct Current) electricity. The electricity is fed into a solar inverter that converts into “AC” (Alternating Current) electricity. The AC electricity powers appliances in your home.
