Do Solar Panels Store Energy?

Solar panels themselves do not store energy; they are designed to convert sunlight into electricity through the photovoltaic effect. When sunlight hits the solar panels, they generate direct current (DC) electricity. This electricity can then be used immediately, converted to alternating current (AC) for use in homes and businesses, or sent back to the electrical grid.
 
To store the energy generated by solar panels for later use, you need a separate energy storage system, typically in the form of batteries. These batteries can store excess electricity produced during sunny periods and release it when there is no sunlight, such as at night or during cloudy days. Common types of batteries used for solar energy storage include lithium-ion batteries and lead-acid batteries.
 
So, while solar panels produce electricity, an additional battery system is required to store that energy for future use.
