One of the most exciting possibilities for future solar energy technology is that of solar cells that can be sprayed or printed on to surfaces like the windows of skyscrapers, the roofs of sports utility vehicles, or the walls of houses. And the expectation is that such technology would be far cheaper than today’s silicon-based solar panels.
Installing solar arrays on the surface of bodies of water is an idea that is catching on around the world. Such installations are especially attractive in places like Japan, where land resources are scarce. In the UK, there are a couple of these so-called “floatovoltaic” projects underway – one outside of London and one near Manchester.
