HOW DO SOLAR PANELS WORK
How do Solar Panels Work?
Silicon is mounted beneath non-reflective glass to produce photovoltaic panels. These panels collect photons from the sun, converting them into DC electrical power. The power created then flows into an inverter. The inverter transforms the power into basic voltage and AC electrical power.
That is a very brief explanation, but some may prefer a more in depth answer the question, “How do solar panels work?” Here is the more detailed response, though it still remains fairly basic.
The Sun
Just the tiny fraction of the Sun’s energy that hits the Earth (around a hundredth of a millionth of a percent) is enough to meet all our power needs many times over.
In fact, every minute, enough energy arrives at the Earth to meet our demands for a whole year – if only we could harness it properly.
Solar energy—power from the sun—is a vast and inexhaustible resource. Furthermore, it represents a clean alternative to the fossil fuels that currently pollute our air and water, threaten our public health, and contribute to global warming. Given the abundance and the appeal of solar energy, this resource is poised to play a prominent role in our energy future.
What are Solar Panels? And how they made?
Simply it is a source of green electricity for you for next 25-30 years.
Solar panel electricity systems (PV), capture the sun’s energy using photovoltaic cells. These cells don’t need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.
PV cells are made from layers of semi-conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced. Groups of cells are mounted together in panels or modules that can either be mounted on your roof or on the ground.
How do Solar Panels work?
- The sun gives off light, even on cloudy days
- PV cells on the panels turn the light into DC electricity
- The current flows into an inverter, which converts it to AC electricity ready to use
- The current is fed through a meter and then into your home’s consumer unit
- Plug in and switch on. Your system will automatically use the free electricity you’ve generated, then switch back to the grid as needed
- Any electricity you don’t use is exported to the grid for others to use.
Energy revolution
Renewable energy revolution happens the same way as other tech breakthroughs. As personal computers appeared in every house, since 1990th same way the solar PV systems soon will be installed on every roof.
