How does the sun make solar energy?
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. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.
What is solar energy and how is it used?
What is solar energy used for? Solar energy uses captured sunlight to create photovoltaic power (PV) or concentrated solar power (CSP) for solar heating. This energy conversion allows solar to be used to power auto motives, lights, pools, heaters and gadgets.
What are the 3 types of solar energy?
There are three main types of residential solar electric power systems: grid inter-tied; grid inter-tied with battery backup; and off-grid. These three broad types vary in how closely connected they are to the traditional power utility infrastructure, known as the grid.
Why is solar power the best renewable resource?
Solar energy is a renewable free source of energy that is sustainable and totally inexhaustible, unlike fossil fuels that are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity. … Using solar power means reducing your energy bills and saving money.
Does the sun make noise?
The surface of the Sun produces sound waves because the surface is convecting and this produces pressure waves that travel into the inner corona. … But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles!

How Solar power is being used today?
Solar energy is used today in a number of ways: As heat for making hot water, heating buildings and cooking. To generate electricity with solar cells or heat engines. To take the salt away from sea water.
What are the benefits of solar cooker?
Solar cookers benefit the environment by:
- Using clean, renewable, and readily available solar energy as fuel.
- Preserving natural resources by not requiring the use of wood or other biomass fuels to cook.
- Not producing dangerous emissions which pollute local environments and contribute to climate change.
How long can a solar panel last?
25 to 30 years
What is best solar panel?

What’s best solar panel type?
Monocrystalline and polycrystalline solar panels
Of all panel types, monocrystalline typically have the highest efficiencies and power capacity. Monocrystalline solar panels can reach efficiencies higher than 20 percent, while polycrystalline solar panels usually have efficiencies between 15 to 17 percent.
Is Solar Power Really Green?
Although solar energy is a clean alternative to fossil fuels, making the panels themselves can have a negative environmental impact.
Is solar renewable or nonrenewable?
Solar energy is a renewable resource, meaning it won’t ever run out or be in short supply. We simply need to build enough solar panels to capture it. Solar energy reaches us via the sun’s rays, while fossil fuels come from ancient carbon-rich remains on earth.
