Solar energy

Renewable energy in Solar City at the museum of Energy
  • How much electricity does a solar panel make? What does it look like and how many kinds of panels exist?
  • Is that a fact? When the speed of wind is doubled, eight times as much energy is generated.
  • Does a solar unit really heat the water?

Explore and discover such facts in Solar City.

Cabin of energy and hydrogen

In Solar City you may find the cabin of energy that get energy from solar panels on the roof, heat from solar air heater and hot water from a solar heating unit. On cloudy days two little wind turbines supply electricity for the cabin.
Energy is stored in two different ways, either the old fashioned way by storage batteries which supply electricity for some of the lamps or as hydrogen with technology of the future. In the solar panels rays of the sun are turned to electricity, this can be used for the light of the lamps or can be furthered into an electrolytic machine. In this machine electricity is used to split water into oxygen and hydrogen. The hydrogen is stored. When the sun is not shining either because of clouds or because it is night, hydrogen and oxygen will be forwarded into a fuel cell, which will turn id into electricity. Clean water is the only thing left.
There is no pollution from electricity and heat generated directly from the sun.

Three types of solar panels

Outside the cabin you can explore different type of solar panels yourself, turn them around to face the sun, make shadows.

Each day the Sun provides the Earth with 7000 time as much energy as we, the human race, consumes.

There is plenty. We just need to find the right way to catch the energy from the Sun.

230 voltage of alternating current directly from the Sun

A facility for demonstrations shows how sunlight can produce alternating current of 230 voltage that can be distributed by the ordinary grid.

Solar Chariot 3

Solar Chariot 3 belongs to the museums collection. It was constructed by students at the Highschool of Engineering in Sønderborg in 1991. It drove 3000 kilometres across Australia only using solar energy.
