Description

Technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a solar energy combined heat and power system. Background technique [0002] Single solar cells cannot be used directly as power sources. As a power source, several single cells must be connected in series, in parallel and tightly sealed into photovoltaic modules. Photovoltaic modules (also called solar panels) are the core component of the solar power generation system and the most important part of the solar power generation system. Its function is to convert solar energy into electric energy, and send it to the storage battery for storage or drive the load to work. [0003] At present, there are two main ways to apply solar energy, one is photovoltaic power generation, and the other is solar thermal utilization. The efficiency of photovoltaic power generation is relatively low, only about 20%, and most of the remaining energy exists in the form of thermal energy. The high-t...
