SOLAR ENERGY
INTRODUCTION SOLAR ENERGY Solar energy is one of the renewable energy sources. Solar energy is the energy produced by the sun, whose main source is taking place in the core of the sun thermonuclear reactions, consisting in the conversion of hydrogen nuclei (H) in the nucleus of helium (He).
The Earth's surface does not reach the entire solar radiation. Part of radiation is reflected by the atmosphere (30%), and part of it is absorbed (20%). The remaining 50% can be used for energy production.
HISTORY OF USE SOLAR ENRGY The world's first solar plate. Pasadena, California 1901.
PROTOTYPE OF SOLAR COLLECTOR Clarence Kemp, Baltimore, 1896.
MODERN SOLAR COLLECTORS Devices for converting solar radiation into heat. Solar energy reaching the collector is converted into thermal energy of the heat carrier, which may be a liquid (glycol, water) or gas (eg. Air).
Modern solar power stations.
METHODS OF CONVERTING SOLAR ENERGY IN ELECTRICITY
SCHEME OF CONSTRUCTION CELL PHOTOVOLTAIC CELL SCHEME OF CONSTRUCTION CELL
TYPES OF SOLAR COLLECTORS SCHEME OF FLAT COLLECTOR
SCHEME VACUUM COLLECTOR
ADVANTAGES AND DISADVANTAGES OF USING SOLAR ENERGY free safe high efficiency no emissions of air pollutants and greenhouse gases ecological easy upkeep / maintenance of equipment the possibility of using the farms away from other sources of energy Disadvantages: difficulty in the use of this energy source difficult for storage high costs of building installations photovoltaic cells are built using harmful substances set cells take up a lot of surface area
Using of solar energy in the world.
LARGEST SOLAR FARM TOPAZ in numbers: built in 2014, TOPAZ in numbers: built in 2014, It generates power up to 550MW, It covers an area of 15,2km², It costs 2.5 bilion dollars, was created two years, satisfies the needs of 160 thousand households, reduces CO2 emissions by 377 thousand, tonnes per year.

POWER TOWER, MOJAVE DESERT, USA 13 km square placed almost 350 000 computer-controlled mirrors. They direct the sun's rays in the direction of water heaters placed on three 140-meter towers The boilers heated the water that drives the turbines Active generate nearly 400 megawatts of power, enough to supply 140 000 households It costs $ 2.2 billion It is owned by NRG Energy, Google and BrightSource POWER TOWER, MOJAVE DESERT, USA

Nevada Solar One - the third largest solar power plant in the world. It is located in Boulder City, Nevada. It generates power of 64 MW. It’s construction was completed in June 2007 It occupies an area of 400 acres. Nevada Solar One Nevada Solar One
THE WORLD’S LARGEST FLOATING SOLAR FARM surface area 180 thousand m2, more than 50 thousand photovoltaic panels, the largest floating solar power plant in the world, power of 13.7 MW, 78W in 2018 should be enough to supply nearly 5 thousand households.

USE OF SOLAR ENERGY IN POLAND The potential of the country: Poland in terms of sun exposure has similar conditions as such Germany and France. The largest supply of energy is achieved in the south of Lublin province. The weakest conditions are in Śląsk - in the area located at the crossroads of the Czech Republic, Germany and Poland It is also poorly sunlit coast (except the western part).
THE LARGEST PHOTOVOLTAIC FARM IN POLAND Photovoltaic farm in Ostrzeszów
SOLAR ENERGY OF PROVINCE PODKARPACIE Division prepared on the basis of the average annual total irradiation and insolation Region I - very good conditions for solar Region II - good conditions for solar Region III - Medium solar conditions Region IV - changing solar conditions
