Description
technical field [0001] The invention relates to the field of solar power generation, in particular to a photovoltaic photothermal heat power cogeneration system and a heat power cogeneration method. Background technique [0002] All material activities of human beings are inseparable from the support of energy. At present, the energy consumed in the world is mainly fossil energy. While fossil energy has brought civilization to mankind, it has also brought many problems, the most important of which are environmental pollution and climate change. At the same time, problems such as energy shortage, resource competition, and environmental pollution caused by excessive use of energy are threatening the survival and development of human beings. Exploring new energy is a way for human beings to face the coming energy dilemma and seek sustainable development. [0003] As an important part of the new energy industry, solar energy is both primary energy and renewable energy. It is ...
