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.
