Less than USD 25 per megawatt-hour of solar power — these kinds of prices are not uncommon any more in sunny regions. Thanks to its continuously falling costs, photovoltaics is on the right track to becoming the world’s most cost-effective source of energy. It thus totally makes environmental and financial sense to build new PV systems rather than continue to rely on conventional power plants.
More than 70 percent of all PV systems connected to the grid now have a battery-storage system. Why? Because more and more cost-effective batteries ensure that solar power is also available after sundown. Anywhere in the world. Even in your home?
