6 FAQs about [6th grade science what energy is solar energy converted to]
How do solar cells produce electricity?
Solar cells convert the energy of photons from the sun into electricity. When the photon hits the top of the cell, electrons will be attracted to the surface of the cell. This causes a voltage to form between the top and the bottom layers of the cell.
What is solar energy used for?
Solar energy is light, heat, and other forms of energy given off by the Sun. Solar energy can be collected and used to heat buildings and to make electricity. Most solar heating systems capture solar energy with a device called a flat-plate collector. The collector is a large plate of black metal covered with a sheet of glass.
What is solar power?
When most of us think of solar power, we think of the solar cells that turn rays of sunshine into electricity. Solar cells are also called photovoltaic cells. The word "photovoltaic" comes from the word "photons", which are particles that make up sunlight, as well as the word "volts", which is a measurement of electricity.
How long has the Sun been a source of energy?
The sun has produced energy for billions of years and is the ultimate source for all of the energy sources and fuels that we use today. People have used the sun's rays (solar radiation) for thousands of years for warmth and to dry meat, fruit, and grains.
How has solar energy evolved over time?
Over time, people developed technologies to collect solar energy for heat and to convert it into electricity. Radiant energy from the sun has powered life on earth for many millions of years. An example of an early solar energy collection device is the solar oven (a box for collecting and absorbing sunlight).
Is solar energy a viable energy alternative?
Scientists have made advances in the efficiency of the solar cell. Today solar cells are around 5 to 15% efficient, meaning a lot of the energy of the sunlight is wasted. They hope to achieve 30% or better in the future. This will make solar energy a much more economical and viable energy alternative. Are there any drawbacks to solar power?
