How do you use energy from the Sun?

The two main ways to use energy from the sun are photovoltaics and solar thermal capture. Solar photovoltaic systems are common for smaller-scale electricity projects (like home solar panel installations ), while solar thermal capture is typically only used for electricity production on massive scales in utility solar installations.

Where does solar power come from?

Any point where sunlight hits the surface of the earth is a potential location to generate solar power. Renewable energy technologies generate electricity from infinite resources and since solar energy comes from the sun, it represents a limitless source of power.

What is solar energy & how does it work?

Solar energy is a clean, inexpensive, renewable power source that we can harness nearly everywhere in the world. Any point where sunlight hits the surface of the earth is a potential location to generate solar power.

How can MIT use sunlight to generate electricity?

An MIT team has developed a novel system for capturing and storing the sun’s heat so it can be used to generate electricity whenever it’s needed. The new system is simple, durable, and inexpensive. Mirrors mounted on a hillside reflect sunlight directly into a large tank of molten salt, which absorbs the heat throughout its depth.

Do solar panels generate electricity at night?

Solar panels generate no electricity at night time. Solar panels can't store energy, so you have to use the electricity they generate when the sun is shining. You need batteries to store the energy generated. These are expensive. – Solar cells convert the light from the sun into electricity.

Is the Sun a good energy source?

The sun is a very powerful source of energy, providing as much energy to Earth in less than 15 seconds as humans use in one day. Most of this energy reaches Earth in the form of light and heat. It's no wonder people have long considered how this energy can be harvested and put to good use.
