A brief history of SOLAR POWER
Why is solar power so good?
How is build?
Norbert Uss 211076
400 year B.C.
The ancient Greeks invented focusing lens. It helped them to kindle fire.
Also they were building their houses in front of south side.
1866 - Auguste Mouchout invented 1st generator of solar power.
Albert Einstein explained photovoltaic effect and use it in production of electicity.
Scientists from Bell Laboratories costructed 1st sollar cell which was made mostly from sillicon.
Energy crisis began intensive development in the field of renewable energy sources.
Solar energy in Europe
The Earth received
170 000 000 GW of incoming solar radiation at the Earth's surface.
It is two types of production
solar energy :
Energy structure in PL
Energy structure in EU
How it costs?
Innovation in Solar Power
nanoengineering in photovoltaic
3D solar cells
2D layers of graphene (and others)
layer thickness = 1nm
Solar Power is the energy of the present and the future
SP is safe and everywhere
SP may be used by ordinary people
Polish energy markets has great potencial for development
SP can replace fossil fuels and make Earth more clean
3D solar cells
Definitely better productivity than conventional solar cells.
Principle of operation
Converts the energy of light directly into electricity by the photovoltaic effect
Solar thermal collector
Principle of production
Collects heat by absorbing sunlight
The term "photovoltaic" comes from the Greek (phōs) meaning "light", and from "volt", the unit of electro-motive force, the volt, which in turn comes from the last name of the Italian physicist Alessandro Volta, inventor of the battery.
The term "solar collector" commonly refers to solar hot water panels, but may refer to installations such as solar parabolic troughs and solar towers; or basic installations such as solar air heaters.
How solar cell works?
How solar collector works?
A solar collector is basically a flat box and are composed of three main parts:
tubes which carry coolant
insulated back plate
This is independet type of energy.
Does not permission to start useing this.
10 000-15 000 zl
In the Netherlands, SolaRoad, the world’s first “solar road,” has defied expectations and has generated about 3,000 kWh of power, enough to provide a single-person household with electricity for a year. Considering it’s only a 70 meters long bike path, the potential for this technology could be big, kind of like photovoltaic technology itself.
This aircraft conducted its first test flight in December 2009, and first flew an entire diurnal solar cycle, including nearly nine hours of night flying, in a 26-hour flight on 7–8 July 2010.
