Solar power is generated when energy from the sun is converted into electricity via solar cells. It is an excellent source
of renewable energy for people who do not have access to power from a grid system. It is most appropriate for countries located in the "Sunbelt", that is, countries that are within thirty degrees north or south of the equator, where there is high direct solar radiation all year round. In Northern latitudes, there is little solar radiation in winter time.

Electricity in the Winter with Solar Power
Female: Hands on stories about solar water and wind energy have provoked huge interest from our audiences looking for green solutions to meet energy needs. Our last story from Western Europe looks at another idea which may be suitable for people who don’t have access to power from a national grid. The technology is being developed by a company in Finland. They are already selling solar cells to surprising customers but are now looking for other ideas to meet demand and case that oil does run out.
The company plats its research plants in solar cells. And it’s here that Jyrki Leppanen is planning to revolutionize energy use.
Jyrki Leppanen: This is a solar cell and this is the main component of solar cells for producing that electricity from light. Light hits the surface here and electricity comes out. It looks nice and simple and it is. It’s clean.
Female: When solar cells produce electricity the power they produce can split water into hydrogen and oxygen. The hydrogen can then be stood and use to make electricity stay in the middle of winter.
Jyrki Leppanen: We have two main components of the systems. In this part we have water which goes inside the electromizer and here we get the product gases out hydrogen and oxygen.
Female: So there are two devices for two different seasons and electric power electromizer which splits the water in summer and the fuel cell in winter which does the opposite by reforming water and generating electricity.
Jyrki Leppanen: Here you can see the main components. This is enough to pull membrane which has on both sides. And you put on both sides the gas flow fields.
Female: All very well in the laboratory but does all these sophisticated machinery work outside? As you might expect Jyrki has been thinking about that too.
Jyrki Leppanen: In this unit we can use electricity all year round whether the sun is shining or not.
