Energy storage converts electrical energy into thermal energy
What is Solar Thermal Energy? A Beginner''s Guide
Solar thermal energy is a technology designed to capture the sun''s radiant heat and convert it into thermal energy (heat), differentiating it from photovoltaics, which generate electricity. Systems like parabolic mirrors or flat plate collectors concentrate sunlight onto a specific area, heating a fluid that transfers the energy to a storage unit.
