Abstract

The invention provides an agricultural light complementary photovoltaic module which consists of six sets of battery strings. Three sets are formed by connecting 10 battery pieces in series. The otherthree sets are formed by connecting 6 battery pieces in series. Two different types of battery strings are arranged in series at intervals and are arranged to form the module. 12 light-transmitting areas are left on the module, so that sunlight can pass through the module to become a crop growth lighting window or channel. A flow channel is arranged on the back of the photovoltaic module. The flow channel is used for low temperature working medium circulation to reduce the temperature of the module and improve the operation stability of the module. The output power is ensured. The conversionefficiency of a photovoltaic system is high.

Description

[0001] The invention belongs to the technical field of production and application of agricultural greenhouses, and in particular relates to an agricultural-light complementary photovoltaic module and its application method in agricultural greenhouses. Background technique [0002] "Photovoltaic complementarity" is a technology that combines agricultural planting or aquaculture with solar photovoltaic power generation. It is called "agricultural photovoltaic complementarity" or "fishery photovoltaic complementarity". Economy. Utilizing the characteristics of no pollution and zero emission of solar photovoltaic power generation, combined with agricultural planting or aquaculture structure, part or all of photovoltaic modules are laid on the sunny side of the greenhouse, so as to realize the purpose of photovoltaic power generation without occupying land and promote the growth of crops , creating better economic and social benefits. [0003] However, the current standard photovo...
