Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun''s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of
But if you''ve already installed solar panels and want to add storage, you can: The battery will cost anywhere from $12,000 to $22,000. Ask your solar installer if they can add a battery to your system. If you purchase a battery on its own or a solar-plus-storage system, you will be eligible for federal tax credits.
