What is solar thermal energy

Solar Farms

Solar thermal energy is the use of solar energy to produce heat. This is an affect you're ever gotten into your car after it has been parked in the sun on a hot summer day

When larger amounts of electricity are needed, solar farms are used. Solar farms have rows of of solar cells on large, flat panels that are tilted towards the sun. The electricity produce on a solar farm is not stored in batteries. It is passed through a special machine that changes it into the type of electricity er use in our homes. It is then sent through overhead power lined to nearby towns and city

How is it used?

This solar farm has nearly 7000 solar panels. It is as big as five football fields and provides enough electricity for 6000 homes.

Solar thermal technology uses the suns energy, rather than fossil fuels, to generate low-cost environmentally friendly thermal energy. This energy is used to heat water or other fluids, and can also power solar cooling systems.Used for house heating, pool heating etc...

Is this form of energy widely used?

solar thermal energy is widely used for so many things such as:

-heating pools

-Space

-generating heat

-Solar hot water systems are used to heat domestic hot water

Solar thermal collectors are panels that can heat your swimming pool all because of the pipes under the surface and when the panel becomes hot, so do the pipes, and warmed water then be used to take a shower or swim.

Photovoltaic Cell

Photograph And Graph

Photovoltaic cells look similar to solar panels but they work in different way. Solar panels are use to produce panels convert the sunlight directly into electricity. A typical example of a device powered by photovoltaic cells calculator only needs a small amount of electricity power to work and can even used from light bulbs from the ceilings.

What are the costs?

Reduced Utility Bills: Businesses that require large quantities of hot water or other fluids must pay for the fuel required to heat those fluids. Solar thermal systems use solar energy to heat and roughly 80,000 pounds of CO2 per year.

Positive aspects

Diagrams And Charts

Renewable. No fuels required

Non-polluting.

Quite. Few or no moving parts

Electricity

Solar energy will last as long as the source, at least for the next 10 billion years. There are two main ways that the suns energy can be used photovoltaic (PV) cells to collect sunlight and transform it into electricity. With the second method large solar power station use mirrors contracted the suns heat to produce steam to turn a turbine.

Can solar energy be stored?

Waste by-products

Many people with solar panels installed in their home don’t realize that the thermal energy collected by the panels can be stored for later use. There are several ways to store solar energy. It can be stored in a heat-of-fusion storage unit or even in water.

Facts

A manufacturing process called photovoltaic in other words the PV cell manufacturing process. This includes a number of hazardous materials. Most of them are used to clean a purify the semiconductor surface. These chemical, includes hydrochloric acid, sulfuric acid nitric acid hydrogen fluoride, and acetone. The amount and type of chemicals depend on the type of all the amount of cleaning that i needed and the size of silicon water. The PV manufacturing must follow U.S laws to make sure no workers are harmed.

The first solar water heater was built in 1767 by a Swiss scientist named Horace Benedict de Saussure. It was a simple wooden box with a glass cover and a black base.When it was placed in the sun, it made the water very hot.

In 1874, the world's largest solar still was built in Chile, South America. It could produce 22 700 liters (6000 gallons) of drinking water everyday. It did so far 40 years.

The world's first solar-powered aircraft flew 260 kilometers (11 000 feet). It was powered by 16 000 solar cells attached to its wings and tail.

How is the energy generated or created?

Chile's Largest Solar

Solar thermal energy is the use of solar energy to produce heat. Solar thermal heat generated is put to practical use heat water or space heating.

Does not produce electricity

Construction/installation costs can be high

Installers not available everywhere

Produce low grade energy (heat vs electricity
