Solar power is also clean power that doesn t generate a lot of pollution.
A diagram showing how solar energy works.
How does solar energy work.
Solar energy works by capturing the sun s energy and turning it into electricity for your home or business.
In off the grid locations solar panels are used as a self contained system to provide electrical power.

Sometimes solar power for heating can be passive.
A standard solar panel also known as a solar module consists of a layer of silicon cells a metal frame a glass casing and various wiring to allow current to flow from the silicon cells silicon atomic 14 on the periodic table is a nonmetal with conductive properties that allow it to absorb and convert sunlight into electricity.
Solar power had a slow start until 2012 when it started to capture a more significant share of the clean energy net generation it rose to its highest ever level to date in 2018 with 66 6 billion kilowatt hours and there is no end in sight with a staggering 49 9 percent annual growth in the united states between 2013 and 2018.
Solar power for heat solar power can be used for heating up homes and other buildings.
A brief video showing how concentrating solar power works using a parabolic trough system as an example is available from the department of energy solar energy technologies web site.
The plants consist of two parts.
Solar energy is even used to keep spacecraft powered.
When we use solar power we don t use any of the earth s resources like coal or oil.
Solar energy diagram 5 concentrated solar power csp concentrated solar power or csp works by using an array of lenses or mirrors to focus a large area of sunlight solar thermal energy onto a small area.
But homes that are already wired to the electrical grid actually share energy back and forth with the grid so that that there is sufficient power for the home at times when the solar panels aren t producing enough energy at night for example or on.
Powering the home with solar energy.
This makes solar power a renewable energy source.
It releases tiny packets of energy called photons which travel the 93 million miles from the sun to earth in about 8 5 minutes.
Our sun is a natural nuclear reactor.
When sunlight hits a solar cell energy is absorbed by the cell s semiconductor material usually silicon.
Let s see how exactly we harness the sunlight for our electricity needs.
As a result we saw a significant growth in solar panels on the rooftops of houses and buildings.
How do solar panels work to generate electricity.
What we see is that solar cells are the building blocks of a solar module also known as a solar panel and when you put more than one solar panel together you get a solar array.
