* To use solar energy instead of normal electricity.


How the sun does provide energy? Earthreceives the sun rays at 174 petawatts (total powe received by the energy from the sun)
Inconming on solar radiation at the upper atmosphere 30 % is reflected in the space, and the other is in the ocean,lands and living things, the sun energy provides the different cycles in which nature can work at perdection.
ELECTRICAL GENERATION WITH SOLAR POWER
Solar power is the conversion of sunlight intoelectricity, either directly using photovoltaics had its precedence from photovoltaics.
ENERGY STORAGE METHODS
Solar energy is not available at night, and energy storage is an important issue becausemodern energy system usually assume continuous availability of energy.
Some methods that are commonly use are thermal energy, molten salts and the use of solar panels.

1. We connect the solarpanel to the voltage converter
2. Connect our battery of 12 volts to the voltage converter
3. Connect the source of voltage supplied to the converter

Solar energy can substitute energyproduced by fossil fuels. We demonstrated that the solar energy is clean energy and we can use this energy forever. Is advantageous for the ecosystem because it do not release any type of gases or ourplanet.
Is a good alternative for us too, because there are not any emissions that can influence our health.
Now the installation of the solar panel isn’t cheap but it helps us make energy, andover the year we can recover our money because we do not use the electrical energy.
