In most places in the world power from new renewables is now cheaper than power from new fossil fuels. The fundamental driver of this change is that renewable energy technologies follow learning curves, which means that with each doubling of the cumulative installed capacity their price declines by the same fraction.

Currently, solar is converted to electricity in solar cells, which cannot store the energy long-term, and separate battery storage systems are inconvenient and expensive. To solve this problem, researchers are trying to find ways to combine the power conversion and storage capacity needs of solar energy into one device.

Systems Integration Basics. Solar-Plus-Storage 101. Solar panels have one job: They collect sunlight and transform it into electricity. But they can make that energy only when the sun is shining. That''s why the ability to store solar energy for later use is important: It helps to keep the balance between electricity generation and demand.
