How Solar Panels Are Used To Generate Electricity

Eventually fossil fuels a non renewable energy source will be depleted and the world will have to turn toward renewable energy.

How solar panels are used to generate electricity.

So a solar panel will make many times more energy than it takes to make it. An inverter is. Even ten years ago this study said it takes about 2 years of energy generation to pay back the energy used to make the solar panel. To generate solar energy the photons radiated from the sun to earth must be collected converted into a usable format and then delivered to an electronic device or the electric grid.

Many solar panels use silicon one of the planet s most common elements. This electricity can then be used to supply renewable energy to your home or. To find out how solar panels work you need to understand how they re made. Solar panels use photovoltaic cells to produce electricity according to the united states department of energy.

Here s the process demystified. With solar panels there s a pretty wide range of efficiency from around 16 up to 23. So how do solar panels actually generate electricity. Solar energy is one of the most affordable renewable energy sources available today.

This flow travels in a circuit of wires that connect groups of solar panels called arrays. Solar panels contain cells of semiconductive material usually silicon usually encased in a metallic frame and tempered glass. In such cells a small electric voltage is generated when light strikes the junction between a metal and a semiconductor such as silicon or the junction between two different semiconductors. Arrays of photovoltaic cells are normally used to collect the energy from the sun and convert it into electricity.

That s almost a 50 difference so switching from cheap panels to the highest efficiency ones on the market can dramatically reduce the number of panels you need. Unlike fossil fuels solar energy is an infinitely renewable energy source. When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect. Wattage is calculated by multiplying volts x amps where volts represents the amount of force of the electricity and amperes amps refers to the aggregate amount of energy used.

Use the highest efficiency solar panels you can. Solar energy solar energy electricity generation. Then it makes energy with no energy cost at all for the rest of its life. Solar energy is a renewable energy resource that is more affordable now than ever before and is used to produce electricity for a wide variety of residential and commercial uses.

Solar radiation may be converted directly into electricity by solar cells photovoltaic cells.
