Solar power is solar energy comes from the sun's light. It is because of the solar energy that there is life on Earth. Without the heat from the sun, the earth would be a cold place and it is solar energy that drives photosynthesis. Solar energy is originally from the energy recovered as biomass, hydropower, wind power and low geothermal energy. Solar energy is the largest part of the electricity and heat production in the earth. Solar energy is used directly by humans via several techniques to produce heat and electricity.

A solar cell is a device consisting of semiconductors functioning as diodes. When these LEDs lit as it becomes electric current in the diode reverse direction. Each individual cell gives a fairly low voltage. It is customary for the most part parallel connect the solar cells to increase the amperage. One can divide the solar panels into two groups, the solar panels with crystalline solar cells and thin film solar cells. Crystalline cells are used more than thin film cells that you can get more energy from crystalline solar panels. They are mostly used in places not reached by the grid instance. of satellites and lighthouses. Other examples are small lights for garden lighting, solar cells are used to avoid wiring. Photovoltaics is also quite common in low-power eg calculator) where cheap solar cells work very well. Around the values ​​then it is most Germany using solar cells and reduces it's Lithuania. Sweden is somewhere in the middle.

A solar collector receiving solar rays and the energy of solar insolation into heat. Heat can move from collector using an appropriate medium. The solar collectors circulates water heated by the sun. The heat is transferred directly to a heating system. What's difficult is to save the excess heat from the hot part of the year until winter, when you need the heat most .. This is done by storing the hot water in insulated tanks that are underground. There are various collectors e.g.. Flat-plate collectors, vacuum solar collectors and concentrating solar collectors, flat plate collectors are the most common. There are also solar panels for pool and helio-state facilities for the production of electricity (solar power plant).

Photosynthesis is the process by which living organisms take care of the energy from light and use it in chemical bonds. Photosynthesis produces energy-rich oxygen and carbohydrate molecules of carbon dioxide and water.

When it comes to allocating energy but so is the renewable energy sources best example. solar, wind or biofuels because they are less damaging to the environment. Oil and coal (fossil fuels) is not so good for the environment, there is a negative impact as it spreads harmful emissions during combustion that affect air and water.

If you use eg solar on his house so it can save many tusenlallar of years, you can have hot water which is heated up by means of pipes located under the solar panels, solar heat will cause the pipes get hot and the water is heated up then as they are transported further to swell insulated tanks which can be found under the house.

One can also get electricity from the solar panels, using the sun as formed the current in the collector and this stream is sent to a "battery" for the house. And the power you can use such as a lamp in your home or blender.

The energy that I use at home is that which comes from the power outlet, and it will swell from reaching water aches, wind pains or anything like that.

Question 1: Will you use solar panels on every house in the future?

Answer: Yes it will be the target up to 80% of all houses will have solar panels on the roof in 2025.

Question 2: Can I just use solar energy for example, an entire household?

Answer: No it can not because solpanelera takes up energy from solar radiations, and on cloudy days so will not radiations produced, so one must also have an ancestor energy source.
